TWS headphones: features and an overview of the best models

The very term "TWS headphones" can confuse many people. But in fact, such devices are quite practical and convenient. You need to know all their features and take into account the overview of the best models before making the final choice.

Bluetooth technology for wireless sound receiving devices began to be used many years ago, but the term TWS-headphones appeared much later - only at the turn of 2016-2017. The fact is that it was at this moment that a real breakthrough was made. Then consumers have already appreciated the opportunity to get rid of the eternally confusing, torn, deforming wires.

The Bluetooth protocol is used to broadcast to both speakers “over the air”. But in the same way as usual, the master and slave headphones stand out.

Large companies quickly appreciated the advantages of such equipment and began mass production of it. Now the TWS method is used even in budget devices. Their technical characteristics are also very different; use is noticeably simplified compared to traditional models.

First, it is necessary to say about the difference between wired and wireless headphones in general. Until recently, many music lovers remained committed to wired solutions. They referred to the fact that the arrival of a signal through the wire eliminates the characteristic airborne interference. The connection will be continuous and smooth. In addition, the cable eliminates the need to worry about recharging.

But even this last point doesn't spoil the reputation of wireless TWS earbuds too much. They give a feeling of freedom, which is unattainable even with a very long wire of impeccable quality. As already mentioned, there is no need to fear that something will get tangled or torn. In addition, wires are simply dangerous for small children and pets. It is even more pleasant to know that you can go or even run anywhere.

In this case, the phone (laptop, speaker) does not "fly away" from the table. And the sound continues to be heard in the ears all the same clearly. The old fears of interference have long been dispelled. High-quality TWS technology allows you to achieve the same efficient broadcasting as over the wire. It remains now to find out the details of its functioning.

Sound transmission in the TWS system, as already mentioned, occurs via the Bluetooth protocol. Data exchange is carried out using radio waves. The signal is encrypted. It is theoretically possible to intercept it. In practice, however, an attacker has to spend too much effort to do this. Therefore, ordinary people (not politicians, not big businessmen or intelligence officers) can be completely calm.

The security is especially high in the latest versions of the Bluetooth protocol. But TWS technology is even more advanced. The two component parts dock with each other (as professionals and experts say, "mate"). Only after that they communicate with the main sound source, and then it sends two independent signals; the source should be as close to the receiver as possible.

Overhead headsets with microphones are often used. This is what is considered a classic version. Such headphones differ from ordinary computer headphones only in that they do not have a wire. Among them there are large professional devices equipped with large ear pads. But in the same way, there are smaller headphones, and even foldable devices that are convenient to take on long trips.

In terms of mobility, "plugs" are much better. In such a system, a thin plastic bow is placed between the headphones. Plugs are inserted inside the ear, which almost excludes the penetration of extraneous noise, but it is this advantage that turns into serious disadvantages. Thus, the introduction of a sound source into the auditory canal has a harmful effect on health. In addition, the danger of not being noticed increases.

There is another option - earbuds. Such headphones first appeared in a set with Apple AirPods. The name itself suggests that the "earbuds" are not inserted inside, but are placed in the auricle. In this case, you can freely control external sounds. The downside is that you won't be able to completely immerse yourself in music or radio broadcasts. However, the clarity of speech transmission over the phone is much higher than that of in-ear devices.

There is also the so-called "arc" type of headphones. We are talking about devices with a "headband". "Hook", it is a clip or ear clip, is much more reliable. However, such a system tires the ears, and for wearers of glasses it is simply inconvenient. The compromise is the occipital arch; it distributes the main load to the back of the head, but part of the impact is still on the ears.

The standard, it is also the basic, sound class unites all models costing up to 3000-4000 rubles. Such devices are suitable for music lovers who are not inclined to significant delights. For 5-10 thousand rubles, you can buy really decent headphones. The highest quality solutions are isodynamic and electrostatic. But they are even more expensive, and besides, it is necessary to focus on the products of the same brand that produced acoustic equipment.

The form factor of the headphones is closely related to their mounting. So, in-channel devices are most often called "droplets". Such a solution does not interfere with wearing glasses, earrings and the like. Overhead devices are safer for your hearing and can accommodate many more controls. But models with a neck block have a purely design value; Technically, this type of wireless headphone is not well developed.

The undisputed leadership in various ratings has Model Xiaomi Mi True Wireless Earphones... The manufacturer promises uncompromising sound quality and intuitive control using sensors. The earbuds sit comfortably and securely in place. Connection and switching on are done automatically. Switching to the telephone conversation mode is also automated: you only need to take out one earphone.

The sound spectrum is not only wide, but also full. All frequencies are demonstrated equally well. Frequency balancing is performed as efficiently as possible, since a neodymium magnet with a cross section of 7 mm is used, inside which a titanium coil is placed. It is also worth noting that Xiaomi Mi True work effectively with the AAC codec.

AirPods 2019 - headphones, which, according to some experts, are overrated. Exactly identical quality can be found in models assembled in distant Asia. But for those who have the money, this opportunity to stand out will be quite enjoyable.

For those who just want great results, the CaseGuru CGPods... This model is quite cheap, while it works in in-channel mode. There are even cheaper designs. But their quality is unlikely to satisfy any discerning consumer. And even those who cannot call themselves a music lover will still feel that "something is wrong."

The sound from CaseGuru CGPods is decent, the emphasis is placed on low frequencies. Moisture protection meets IPX6 level. The technical parameters are as follows:

• receiving radius - 10 m;
• Bluetooth 5.0;
• Li-Ion battery;
• duration of work on one charge - up to 240 minutes;
• a pair of microphones;
• full technological compatibility with the iPhone.

If you choose the i12 TWS, you can save even more. Miniature headphones also work with the Bluetooth protocol. They are equipped with a decent microphone. Externally, the device looks like AirPods. The similarities are evident in the technical "stuffing", including touch control and sound quality; it is also nice that there are several available colors at once.

Practical characteristics:

• signal reception radius - 10 m;
• electrical resistance - 10 ohms;
• range of broadcast frequencies from 20 to 20,000 Hz;
• efficient development of Bluetooth 5.0;
• acoustic sensitivity - 45 dB;
• guaranteed period of continuous work - at least 180 minutes;
• charging time - up to 40 minutes.

The next model is next - now SENOIX i11-TWS... These headphones are capable of delivering excellent stereo sound. The device, like the previous ones, works under the Bluetooth 5.0 protocol. The battery in the box has an electric capacity of 300 mAh. The battery of the headphones themselves produces no more than 30 mAh of current.

Ifans i9s can be considered as an alternative. The package bundle is quite decent. By default, the headphones are colored white. Their electrical resistance is 32 ohms. The device is compatible with both iOS and Android. Other options:

• DC 5V model input;
• accelerated broadcasting of sound via Bluetooth (version 4.2 EDR);
• microphone sensitivity - 42 dB;
• total recharge time - 60 minutes;
• signal reception radius - 10 m;
• the duration of the standby mode - 120 hours;
• talk mode operation - up to 240 minutes.

But it is not enough just to read the descriptions of the models. There are a number of subtleties that are often overlooked by consumers.

The sound quality and power consumption directly depend on this, and therefore the service life without recharging. In this case, it is important that the corresponding version of the protocol is supported by the device that distributes the sound.

If there is an opportunity to pay an additional amount for the ultimate sound quality, it is worth focusing on models with aptX. It is believed that such a codec is exactly what guarantees optimal performance. However, one must understand that not everyone recognizes the real difference. This is especially difficult if the gadget does not support aptX technology.

If you plan to use headphones “just at home and in the office”, then you should choose models with a radio transmitter. This module consumes more power than traditional Bluetooth. It is also unknown exactly how many TWS devices support this technology. But on the other hand, the signal will be more effective to overcome walls and other obstacles. For those who still cannot decide on the choice between wired and wireless headphones, there are models with an auxiliary cable connector.

It is also useful to pay attention to the presence of a microphone. (if only because this is a characteristic feature of some actual versions). Active noise cancellation works quite effectively. The bottom line is that external noises are captured through the microphone, which are then blocked in a special way. Which one exactly is already a trade secret of each development group.

The frequency range tells about the spectrum of the processed sounds. The optimum range is 0.02 to 20 kHz. This is the general range of perception for the human ear. Sensitivity is also loudness. Ideally, it should be at least 95 dB. But it is important to understand that it is not recommended to listen to music at high volume.

To connect TWS headphones to your phone, you need to activate them on your Bluetooth device.Only then you need to enable the same option on the phone. They give the command to look for suitable devices. Pairing is no different from virtual “docking” any other device.

When the headphones are in active mode, they allow you to receive incoming calls. You will only need to press the corresponding button once. If it is decided to reset the call, the button is simply held down for a couple of seconds. You can interrupt the conversation by pressing the same button right during the conversation. And the key also allows you to manipulate the music: usually, a light press means pause or unpause, and a quick double click - go to the next file.

Usually recharging is done via the USB port. Connection to PowerBank or to a regular power grid helps to speed up the process. In most models, the indicators turn red when charging, and turn blue after charging.

There are a few more subtleties:

• you should carefully choose a sound profile so that it meets the needs of the user;
• when connecting the headset to the computer, you must not allow it to initiate the connection (otherwise the settings will go wrong);
• devices operating at adjacent frequencies should not be allowed to interfere with the operation of the headphones;
• you need to carefully monitor the sound volume and avoid prolonged listening to even quiet songs.

Some devices allow you to simultaneously recharge headphones and a case (this is clearly stated in the instructions). Some headphones - for example the SENOIX i11-TWS - give English voice commands and beeps when connected. If there are no such signals, then the device is frozen. In this case, a restart of the headphones is required.

The TWS IPX7 has an impressive reputation. The package bundle is quite decent. The good news is that charging takes place directly from the computer, and in just 2 hours. The device is appreciated for its stylish look and pleasant tactile sensations. Turning on occurs automatically as soon as the headphones are removed from charging.

It should be noted that despite the lightness, the product keeps well in the ears. The sound is better than one would expect at this price point. The bass is quite saturated and deep, no one notices the unpleasant squeak at the "top". No less good news - the pause is set by switches from any ear. In general, it turned out to be a good modern product.

The i9s-TWS earbuds also receive positive ratings. Users note that the earbuds maintain a charge for 2-3 hours. The useful thing is that recharging is done right inside the case. But the cover for the case is too thin, easily torn. And it gets clogged even faster.

The sound is somewhat inferior to that produced by the original from Apple. However, the product justifies its price. The sound through the microphone is also inferior to that provided by the original product. But at the same time, the clarity is quite enough so that you can hear everything. The details are quite high quality, and the materials used leave an impression of good quality.
