Best Wireless Earbuds Under 50 Euros For Heart Touching Sound

With the official presentation of the new iPhone without a 3.5mm connector, the debate is on the table: is it time to retire the cables? The smartphone has become one of the core center for listening to music, anywhere, anytime. But do all cordless handsets meet minimum requirements and sound qualities?

2016 has become a turning point: more wireless headsets are already sold than wired. Beats, the world’s leading manufacturer acquired by Apple, long ago forgot cables for the best models in its fleet. In any case, the trend seems to be towards the new USB-C Digital Audio protocol, more efficient and with more future possibilities.

A major technological leap

Wireless headphones have always invited the distrust. Coding technology, until recently, was not up to the task. From radiofrequency we go to bluetooth and NFC (near field communication), which has not been a little path of roses.

Best Wireless Earbuds

What we should be clear is that with the bandwidth of the new Bluetooth and WiFi protocols, the question about quality is no longer valid. No more extreme compression or delay in audio . Moreover, switching to wireless models in most cases implies the jump to models that include their own DAC . The DAC is the hardware in charge of transforming the digital information to analog. Put another way: take all those zeros and ones and make them something audible that our hearing instruments interpret. So if the DAC is up to it, in the case of digital music, the quality can be 1: 1 with respect to the source. In theory, at least.

A for the PERFECT hearing aid

Beats, Bose, Jaybird, Skullcandy … everyone knows the most popular brands – not necessarily the best, as we will see. First we must focus our search. We could classify wireless hearing aids into three subcategories:

  • Sports: for any outdoor activity , with tolerance to rain and sweat, to withstand the mistreatment and abuse inside and outside the home. The keyword is waterproof .
  • Domestic: headphones designed to go from room to room , office in office. Of study or for retransmissions by Youtube, to play without obstacles or to be thrown in the bed reproducing the audio from the desk of another room.
  • HiFi: More technical earphones for the ears . High performance systems that are complemented by a High Definition DAC. And of course, with an emitting source to the height. Forget about Spotify.
 Regardless of the type of headset, the three values ​​that we must take into account when choosing a good wireless model are:

  • Autonomy : most oscillate between 5 and 10 o’clock. But here we also depend on our smartphone , tablet or system. We must look for a headset that does not sacrifice quality when the battery is running low or increases weight / size disproportionately.
  • Construction : Most wireless headphones include some type of head or ear support: neck, clip, elastic band, and so on. Comfort is absolutely key and should be able to operate in more hostile environments than just two meters from the sofa.
  • Features : pairing, compatibility with codecs , and so on. The ultimate goal of a handset should always be the quality of transmission and reproduction. Everything else is accessory.

    From 5 to 50 euros

    Coulax QY8 (€ 15.99)

    We start with a model that is a gift for the capabilities it has. For a little more than 15 euros we take a model compatible with the profiles HFP, A2DP, APTX + EDR (up to 96KHz), with Bluetooth standard 4.1, CVC 6.0 noise cancellation – which translates into intelligent filtering of environmental noise – and The possibility of pairing with two independent devices simultaneously. They are not very comfortable, although flexible, light (just 18 grams), an 80mAh battery that supports up to 7 hours of playback and a range of operation up to 10 meters away.

    Mpow Cheetah (€ 19.99)

    A model a bit outdated but quite stable and solvent performance. For about 20 euros we have a model of identical technical performance to the above mentioned, with two relevant notes: they are much more comfortable – the box includes 5 pairs of stabilizers ( earbuds ), three of them waterproof – and offer a more powerful sound, with greater packing. By contrast, they go up to almost 60 grams, its battery seldom reaches 6 hours and receives signal up to 9 meters . As for qualities you will not have much to worry about: it operates in the range of 2.4 GHz, standard Bluetooth 4.1 (in addition to the 4 official profiles) and include a RSE PLC chip with a very capable performance.


    Aukey EP Sport (€ 20.99)

    Also compatible with the A2DP, AVRCP and Bluetooth 4.1 protocols, this small is especially popular among some users for its ergonomics. Its battery -Li-Polymer rechargeable 120mAh- offers about 5 hours of music and a charging time of less than 2 hours . Its maximum range is 10 meters and, if we had to emphasize an element, would be its perfect sound coherence: steady bass, pleasant and not very sharp treble. For this price it’s hard to find anything better.

    Philips MyJam Fresh Tones BT (€ 40.99)

    By the hair is cast this model, the smallest of the SHB family . Good headset and best friend, offer drivers above 10mm (14.2 to be exact) which translates into thicker bass and greater sensitivity (107 dB) . Its finish is somewhat more careful than most of the mentioned: flat cable (Flexi-Grip), does not weigh 3 grams, “classic” design (intraural with vertical drop) and compatibility with version 4.1 of Bluetooth. Of course, the battery runs out in a heartbeat: only 4 hours.

    In this price spectrum, we should not forget some headphones with microphones: the Sony SBH20 and Philips SHB 5100 have been around for some time and are ideal for taking calls and, although they do not offer the sound package of other models, they are more versatile thanks To its Multipoint + NFC connectivity.

What Is USB DAC & How It Works?

DACs are fashionable. And it is perfectly understandable. The popularity that is being acquired through the Internet distribution of digital music encoded in high resolution formats has caused many users want to make us a DAC that allows us to enjoy it with the highest possible quality. This is the reason why in Xataka Smart Home we usually talk about them with relative frequency.

Several of our readers have suggested that we prepare a post in which we explain in a simple way what a DAC is and what exactly we can do with it. So, said and done; here it is. Although we have explained it before , I will try to develop it with the maximum possible rigor, but, at the same time, in a simple way, and, above all, contributing some new ideas to what we have counted until now. Of course, it is likely that after reading it, you begin to think seriously about becoming one.

Let’s go there……

Digital to Analog conversion


The first thing we have to keep in mind is that the music contained in our CDs, SACD, the hard disk of our computer or our mobile phone, for example, is coded in the digital domain. This is something that we are probably all clear of, and we also know that old cassette tapes and vinyl records contain music in analog format. Now that we have remembered that our music can be stored in digital or analog format (if we like vinyl records), we must remember that the speakers of our stereo need to receive a continuous electrical signal, and therefore analog, If we want them to sound. We can not send you the zeros directly and the ones we can extract from a digital media, such as a CD.

Cambridgesilver (1)

The work done by Digital to Analog Converter (DAC ) is to pass a signal from the digital domain to the analog . No more no less. There are also devices that perform the opposite process, and that, therefore, manage to transform an analog signal into a digital one, but these are not the ones that interest us at the moment. The way a CAD performs this conversion process is beyond the scope of this post because of its complexity, but we may approach it in another post later.

Most of the CD, DVD and Blu-ray Disc players we all have at home incorporates a DAC inside . But we can also find it on our mobile phones, computers, and, in general, any device that is capable of playing digital music and send it directly to speakers or headphones. If we already have it inside many of our devices, why do we want a dedicated DAC such as the McIntosh D150 we talked about yesterday ?

Let’s see.

Reasons to get a DAC

Essentially, we can have two reasons to become an external or dedicated DAC. The first is, simply, to process with more precision, and, therefore, quality, our digital music. Each converter can use a circuit topology and a very different conversion chips, and these differences precisely determine its final sound quality . If we have a CD or SACD reader and want to improve its sound, we can use one of its digital outputs (usually optical or coaxial) to send to a high quality external DAC the digital data stream it extracts from our disks.

Dc 901 Back E

The other reason for getting a dedicated DAC is that the latest models are compatible with a huge amount of high-resolution encoding formats, such as PCM up to 24/32 bits and 192/384 kHz, DSD or DXD. If we want to enjoy the great sound quality that these formats can offer us, and the integrated DAC in our stereo is not ready to process them, the best option happens to be us with a new converter .

If we keep in mind all that we have reviewed so far we can easily intuit what inputs and outputs we can find in a DAC. As we have seen, these devices receive digital signals, so they must necessarily incorporate inputs for digital signals, such as USB, optical (EIAJ / TosLink), coaxial (S / PDIF), etc. And its outputs will be of analog type. However, the latter can be, at the same time, two types: single ended or balanced (if you want to know them better you can have a look at this other post in which we talk about them ).

Before you buy, Investigate

Currently in the market we can find dozens of CAD with very different benefits and prices also very different. Converters designed to coexist with smartphones and tablets, reference DAC designed to work side by side with high quality transport mechanics, preamplifiers and CD players with built-in DAC that can be accessed externally … Of everything. For this reason, I suggest that you think carefully about which devices you need to use and which formats to decode , and that you choose the one that best suits your needs. It will not cost you to find it.

How Noise Cancelling Headphones Work To Improve Sound Quality

One of the determining factors in the final sound quality we perceive through our hi-fi headphones is ambient noise , especially if we live in neighborhood noises and we do not have an acoustically isolated room, or we are in public places or just traveling In any means of transport.

There are several formulas to avoid annoying environmental noise, or at least to minimize it to the point that it is no longer perceptible to a large majority of users, which we can classify in active and passive technologies .

Passive techniques are commonly known as acoustic insulation systems and their mission is to prevent the external sound from entering our auditory system, which is why it is usual to interpose insulating material between the casing or outside of the earphone and the part that will go Stuck to our ear or ear.

Noise-Cancelling Headphones Work

It is the simplest, cheapest technology that is usually used in all headphones with more or less fortune. However, it has the disadvantage that it does not cancel the external noise, it only attenuates it (in values ​​that can go from 8 to 20 dB depending on the materials used, whether they surround all or part of the ear or if they are intrauricular) and depending on the insulation May not work well at low frequencies (below 100 Hz).

Active Noise Canceling: What it is and how it works

If we want to go a step further and eliminate outside noise as much as possible, we must opt ​​for those known as Active Noise Control ( ANC ) systems. What does it consist on? For they base their operation on the theory of waves interference.

Sound is a low-frequency wave (the human perception limit is below 20 or 22 kHz) which complies with the principle of superposition of wave theory, which could be summarized as that when two or more waves Find in the same point, the resulting total wave is the vector sum of the incident waves.

Thanks to this feature it is theoretically possible to create an artificial sound wave that added to the original wave results in the total or partial cancellation of a part of it, is what is known as destructive interference of waves.

Acoustic waves

Moved to the world of headphones, the original signal is the sum of the signal we want to hear, i.e the music, plus background ambient noise surrounding us. The artificial signal will be a sound wave created by an electronic circuit that will cancel this ambient noise.

As it does? First, through one or more microphones located in the body of the headset or the cable picks up the noise that comes to him and by processing it generates an equal but opposite phase signal that when reproduced next to the original signal will give as Resulting in destructive interference and a sound free of external noises. Or that at least says the theory, since active noise cancellation is not 100% perfect (although it usually manages to reduce noise by more than 25 or 30 dB) and its operation is limited by the main frequencies that conform The noise signal.

Active noise canceling headphones

So, for example, the usual thing is that it works very well if we have a low frequency noise and constant type like the one produced by the engine of an airplane, a car, even the hum of the fans of a computer equipment ( here you have a Example of this technique applied to actively reduce the noise of the typical fans of the computer). In fact, headphones incorporate preset listening modes for each of these situations, such as the ATH-ANC9 QuietPoint .

However, its effectiveness decreases with high frequency sounds, although fortunately this is where the efficiency of the aforementioned acoustic insulation improves, so that the total resulting insulation factor is usually very good.

Active Noise Canceling: Main Drawbacks

The first and most immediate disadvantage of active cancellation versus only passive systems is that they need external power to operate the noise detection system and wave generation in phase shift. This power is usually provided either by the USB connector of the headset (if using this system), or by small batteries (usually AAA type) or rechargeable batteries, a factor to consider if we think of taking the headset travel.

Another disadvantage is that the active cancellation system itself introduces modifications to the final signal , which in some cases degrades it due to the imperfections of the noise detection system, which can introduce annoying background hisses , which are generally more noticeable the more Cheap is the technology used.

The cost is its third main drawback, since incorporating the system into a headset causes its price to increase appreciably . Also, it should be noted that in some models (especially in the older ones), the fact of carrying an ANC system implied an increase in the volume and weight of the equipment, something that has fortunately been minimized with the passage of the weather.

Best 5 Microphones Under €300 To Record Quality Voice

This is the list of options you would consider if you could only spend € 300 on a Microphone primarily intended for Voice Recording. Know the different options and my final choice.

The idea of ​​this list is to select a Microphone that you can use, mainly, to record voices but that also you can use to record some Music Instruments. Basically it is that you can use it as an off-road Microphone: for everything.

Best Microphones For Quality Sound

That’s why all the options are Large Membrane Condenser Microphones and none of them works via USB. You will need an interface with Phantom Power to work with them and start setting up a more professional Work Environment.

1. AKG C3000 | € 195

Buy an AKG C3000 MicrophoneIn the lower price range of this entry we find one of the best professional brands and a comprehensive catalog of prices and benefits for a company respected by that relationship.

I find the right choice as the first Microphone to record Voices. Its -10 dBs Attenuation Pad will allow you to work with strong signals even though I miss a High Pass Filter to reduce the Proximity Effect and the bass resonances.

It has a unique Cardioid Polar Pattern that will serve to capture Voices frontally , but you will not enjoy the versatility necessary to record several Voices or some Instruments. Be that as it may, it is an excellent option below € 200.

2. SE ELECTRONICS 2200A IIC | € 229

Buy a Microphone SE Electronics 2200AThis Microphone replaces the old sE2200a from the same house that, as they both like to say, was Amy Winehouse’s main vocal microphone. Marketing aside, it’s worth noting the detail for that cheap is not synonymous with Poor Quality .

You enjoy the same attenuation pad of the C3000 although it adds the necessary High Pass Filter . In the same way, it has a single Cardioid Polar Pattern.

It supports Sound Pressure Levels up to 135 dBs which, translated into Spanish, means that it can handle the loudest Mc’s … although not as well as the next model.

3. AUDIO TECHNICA AT2050 | € 235

Buy an Audio Technica AT2050 MicrophoneClassic among the classics in this price range, the AT 2050 includes, this time, 3 selectable Polar Patterns : Cardioid (like the two previous models), Omnidirectional and Figure 8. This extra versatility will go from fable to record more than One Vocalist at a time and to experiment with some Instruments.

Its High Pass Filter at 80 Hz and the Attenuation Pad of -10 dBs are on the same wave as the SE we have seen although it supports up to 149 dBs SPL, well away from the 2200a II C. It also includes the AT8458 Suspension and a Soft Case .

This is one of the best options you can think of right now if you are thinking of buying a microphone.


Buy a Rode NT2-A MicrophoneThis Rode Pack is made up of the Rode NT2-A along with the Deluxe SM6 suspension with integrated Antipop, a 6 meter XLR cable, a soft case and a DVD tutorial in case you do not have enough with the Production HipHop

You can work with the same 3 Polar Patterns as the previous model but in this case you can set the High Pass Filter at 80 or 40 Hz and the Attenuation Pad at -10 or -5 dBs, allowing you more versatility and its 147 dBs SPL will support you whatever.

I find it interesting to include in the list a Combo of this type that will go to you if you do not have Equipment and you need to do with the whole Initial Pack at a reduced cost.

5. SE ELECTRONICS SE 2200T | € 298

Buy a SE Electronics 2200T MicrophoneCuriously, its characteristics are more limited than some more economical models. It only features a Cardioid Polar Pattern, a Switchable High Pass Filter at 100Hz, a -10 dBs Attenuation Pad, and a maximum SPL of 130 dBs. It is also the only one on the list that works with an external Power Supply (on the same wave as my beloved Studio Projects T3).

However it works on an own SE valve (unlike previous solid state models) and that changes the internal electronics of the microphone and its sound. If you compare the model 2200a II C with this you will notice a richer and more open Sound , especially in the Voices and Acoustic Guitars.

How to Choose a Bluetooth Wireless Speaker

Bluetooth Wireless SpeakerPrice, design and what else should we look at when choosing the best speaker for our needs ? Here are some of the features that you should keep in mind when deciding on one or the other Bluetooth speaker.

Philips Sbt75blk Connectivity

Listening to music wirelessly is comfortable and every day the sound quality is higher. Although there are exclusively WiFi speakers, these have their natural habitat very limited to home and offices. However models with Bluetooth connectivity span a wider market. Although it is the main connectivity that we are going to look for, it is not necessary to leave aside that the speaker that we are going to choose has more forms of connection.

The main one would be a jack input, usually 3.5 mm, in case you want it or need it, you can use the Bluetooth computer speakers as a cable with almost any sound source. The same happens with the USB port that some models include for direct playback of audio content or even in very specific cases, there is the option to play directly from memory cards.

If you want to be able to play directly from a USB port, make sure that the one that includes the model you want to choose is not used exclusively for updates. In any case, if so, it is good news because it can extend the life of our device by updating it with new codecs, for example.

Philips Bt3500w

Another type of connectivity much appreciated in a Bluetooth speaker would be the NFC . Many of the most current models already integrate mainly to facilitate the pairing with smartphones. Simply approach the sound source and the loudspeaker and go, without having to search, enter menus, download configuration applications or enter pairing codes.

Type and Bluetooth profile of a speaker

Bluetooth Portable Speaker

What we are looking for is clear that it is a Bluetooth speaker , but if you look at the different models that are on the market, you will find different versions that have associated certain profiles of use of such base connectivity.

The Bluetooth version directly affects the bandwidth, and in the market we find models that do not fall as a rule and a 3.0 specification, although ideally they were already 4.0 to take advantage of lower consumption, key in a speaker Wireless. Also the Bluetooth class (1, 2 or 3) will determine the range.

If you are looking for a Bluetooth speaker with maximum sound quality, the APTx codec is now the best behavior
As for the profile, the one supported by our speaker is one or the other will determine from the functions of the same to the quality of sound that we can get. Although the Bluetooth connectivity indicates the wireless connection, the profiles determine the functions capable of performing both source and receiver . Both must be compatible with the same profiles in order to use them.

Also ReadBest Mobile For Less Than 100 Euros

If we focus exclusively on what is directly related to sound, the main Bluetooth profiles are:

A2DP . The most widespread is the main one used to transmit audio over BT connectivity.
AVRCP . Profile destined to the remote control of different functions of audio reproduction.
HFP . This profile, as we will see later, is necessary to be able to use a speakerphone as hands-free and make / receive calls from our smartphone.

HSP . It is the most used to receive audio content in headphones.

The maximum sound quality that we can receive via Bluetooth is marked by the profile and the supported codecs , which will usually compress the sound so as not to exceed the maximum bandwidth allocated to that profile.

Quality of portable Bluetooth speakers

The most widespread we have already said is the A2DP, which usually supports the SBC codec , although this profile supports others as MP3 or AAC whenever both source and speaker support. SBC leaves us an audio with bitrate of 320 kbps in stereo, more than enough for the services of streaming.

But if the content that we are going to send to our Bluetooth speakers exceeds that quality and we want to keep it with the lowest possible losses, it is convenient that we focus on the APTx codec , already available on high-end Bluetooth speakers and equipment. With this codec we obtain CD quality without sacrificing excessively the sound and also the latency is improved (although in this case the advantage is more for the audio that accompanies a video). Other solutions already come into Hi-Res audio (like LDAC) to which some brands are being uploaded.

In the connectivity of our future bluetooth audio system it is advisable to be attentive to how many devices it supports linked at the same time as the equipment of which it keeps the link. At home we can have several smarpthones, tablets or even laptops and desks from which we want to send audio to a Bluetooth speaker. If we already have them paired it is more direct to start sending audio when we want, without waiting.

Maybe some of you already knew about the existence of this mobile. If so, it would not be unusual for you to have discarded it because it was not compatible with the 800 MHz frequency band, which is used in Spain for 4G. However, it has launched an international version that does have 4G compatibility in the 800 MHz frequency band . And it costs less than 100 euros . We can buy it for about 90 euros. Of course some stores sell it somewhat more expensive.

The mobile has a 5-inch screen with an HD resolution of 1280 x 720 pixels . I have still used mobiles with this resolution and the truth is that I have not left the feeling that they are mobile with low resolution image. Logically, there is a difference with a mobile with Quad HD display.

The Xiaomi Redmi 4A processor is a Qualcomm Snapdragon 425 , a very current quad-core processor, which also supports Quick Charge technology. Its RAM is 2 GB , which seems quite enough for a mobile that does not exceed 100 euros in price, with an internal memory of 16 GB. Its main camera is 13 megapixels , while its front camera is 5 megapixels. But the best thing is that with these basic features, integrates a battery of 3,100 mAh, which will give us more than a day of autonomy.

Less than 100 euros for a mobile that offers almost the same as mobiles that cost two or three times more. Sometimes you even have to consider if buying a mid-range mobile has logic.
