Comparison Corsair Void RGB Elite Wireless vs Corsair Void Pro RGB Wireless

In this paragraph, first of all, the method of mount on the ears is specified; according to this parameter, modern headphones are divided into overhead, earbuds, in- ear, glasses and headbands. For on-ear models, the acoustic design (closed, semi-open, open) can also be specified here, as well as the presence of such features as a full-dimensions (over-ear) design (in the absence of this feature, such headphones are called “on-ear”, or simply on-ears), swivel earcups, auto-adjust headband, or even the mid-2021 trend, Cat Ears. And details such as a rigid headband, behind-the- ear mount, mount on the neck and the ability to fold can be combined with almost any method of placement on the ears (with a few exceptions - for example, on-ear models are not attached to the neck).

Here is a more detailed description of the different ear placement options:

- Overhead. Overhead headphones are called headphones that are located outside the auricles, covering the ear from the side (“regular” overhead models) or completely (full-sized Over-Ear - see below about them). In any case, such models are quit...e large in dimensions. This, on the one hand, simplifies the creation of headphones with advanced sound characteristics, and also allows you to apply some specific tricks without much difficulty - for example, several emitters or support for multi-channel surround sound. On the other hand, the dimensions of the "ears" complicate the transportation and use on the go. In addition, it is worth considering that most overhead models have a headband, which is why they are poorly compatible with complex hairstyles and some headdresses. Models with rigid temples and behind-the-ear fasteners do not have this disadvantage, but they also have their own specifics (see below).
On-ear headphones can have different acoustic design:

• Closed. Models with a high degree of sound insulation, protecting the user from extraneous sounds as much as possible. This design contributes to a rich sound (especially in the bass range) as well as a very powerful immersion effect, making it well suited for home use (including computer games) and noisy environments. But it is not recommended to use such “ears” on the street: complete isolation from surrounding sounds in such conditions can be unsafe. In addition, it is believed that a completely closed design slightly degrades the sound fidelity.
• Open. Headphones with a minimum level of sound isolation, allowing most of the external sounds to pass through. They are inferior to closed ones in terms of power and saturation of sound, as well as efficiency in noisy environments; in addition, the sound from such headphones is well audible to others. On the other hand, open models generally provide more authentic sound and are better suited for situations where you need to control your surroundings, such as outdoor applications.
• Semi-open. A kind of compromise between the options described above: headphones with better sound insulation than in open models, but still not up to closed “ears” in this indicator. For some users, this middle option may turn out to be more comfortable. In addition, semi-open headphones are also appreciated in professional work with sound: they retain the richness of the bass and at the same time do not create the distortion typical of a completely closed design.
• With rigid shackle. Rigid headband allows you to securely fix the ear pads on the ears. A close analogue of the rigid headband is the headband of full-dimensions headphones, but in contrast to it, the headband is worn on the back of the head, and not on the top of the head. For this reason, hard temples are made mostly without padding, from bare plastic/metal. Headphones with a rigid headband most often have a sports focus, because the headphones, located on the back of the head, will not fidget on the head even with intense running. On-ear headphones are pressed tightly against the auricles, but the speakers themselves are placed on the outside of the auditory canals.
• Cat Ear ("ears"). On-ear headphones in an interesting design - with an imitation of cat ears on the headband. Such an addition does not affect performance, however, the "ears" look unusual and can be a great addition to the bright, original style of the owner. Cat Ear headphones are especially popular among teenagers.

- Intrachannel. Tiny earphones that, when used, are inserted directly into the ear canals. For ease of wearing, rubber or silicone pads are provided, often several of these pads are included in the kit to adjust to a specific ear dimensions. This design combines compactness and advanced performance: earbuds “ears” are often comparable to overhead ones in terms of sound volume and bass saturation, and the degree of sound insulation is very high (many models can even be used as impromptu earplugs). On the other hand, complete isolation from external sounds can sometimes be a disadvantage - for example, when cycling or walking along a busy street.

- Intracanal with a rigid shackle. In-ear headphones are laid inside the auditory canals, which allows them to be fixed as securely as possible in the ear and not fall off. The presence of a rigid bow further increases the reliability of fixing the headphones. This type of headphone is well suited for sports. The rigid headband and earbuds design of the sound emitters keep the earbuds securely in place even during intense running.

- Inserts. Also known colloquially as "pills". Similar to earbuds headphones, these headphones are small in dimensions and are placed in the auricle - however, not in the depth of the auditory canal, but at its very beginning, almost outside. This makes the earbuds somewhat simpler in design and cheaper, but it is more difficult to achieve rich sound and advanced acoustic characteristics in them. Such models give a rather low sound insulation, but this can be both a disadvantage and an advantage, depending on the situation. And some headphones of this type have an elongated shape, due to which they sit deeper in the ears and, in terms of their capabilities, can approach earbuds models.

Separately, it is worth noting that earbuds models and earbuds do not use headbands - the headphones are either completely separate or connected with a device such as a rigid headband or neck mount. So these headphones can be worn with almost any hairstyle or headdress without any problems.

— Inserts with a rigid headband. The earbuds are simply inserted into the passage of the auditory canal without penetrating deeply into it. This is not the most reliable way to fix the headphones, but due to the presence of a rigid headband, the earbuds gain a firm fit and a secure fit. The headphones themselves have an open sound path design, and therefore reproduce audio with a noticeable distortion of the original sound signal. But at the same time, the open acoustics scheme allows you to clearly hear what is happening in the surrounding space.

As for additional design features, they can be as follows:

- Full-dimensions Over-Ear. On-ear headphones (see above) in which each cup completely covers the ear and fits snugly to the head. The cups themselves in such models are made quite large and are equipped with characteristic soft "borders" around the perimeter of the inner side - these borders are adjacent to the head, so that the auricle is actually inside the cup. The main advantage of this design is that the headphones (with the right dimensions) practically do not touch the user's ears and do not put pressure on them - this is especially comfortable during prolonged use. In addition, it is easier to achieve high-quality sound insulation in Over-Ear models (although among them it is quite possible to find models with semi-open and even completely open acoustic design). The main disadvantage of such devices is bulkiness and inconvenience in transportation and use on the go. In addition, when wearing glasses, the Over-Ear cups usually press on the temples from the sides, which can cause discomfort.

- Auto headband adjustment. A headband that can automatically adjust to the dimensions of the user's head. Such a headband usually consists of two parts - a rigid, usually metal, base, and a soft inner part, which is adjacent directly to the head. It is the inner part that is able to stretch, and the user only needs to place the cups on the ears so that it is comfortable - and the headband itself will increase to the desired dimensions.

- Rigid bow. A shackle made of rigid material that connects both headphones and is located on the back of the head when worn; in some models it can also serve as a neck mount (see below). The advantage of such a device over the classic headband is that the bow can be used with almost any hairstyle and headgear. On the other hand, in earbuds models and earbuds (see above), this feature makes the headphones more bulky, and in over-ear models it makes sense to use it only with conventional models that are not related to full-dimensions Over Ear. Therefore, as well as for a number of other reasons, in our time the bow is not particularly popular.

- Ear mount. Attachment that allows you to fix each earpiece directly on the ear; as a rule, it has the appearance of a characteristic bow. This feature is found in all types of modern "ears", except for Over Ear (see above), and its specific meaning depends primarily on the main way the earpiece is placed on the ear. So, for earbuds models and earbuds, the behind-the-ear mount provides additional reliability of retention: the likelihood that the earpiece will fall out of the ear is reduced to almost zero due to such a retainer. In overhead "ears" this feature is much less common, and its main idea is to do without a headband or a rigid headband - in some cases, these design elements are redundant.

- Attachment to the neck. A feature that is found exclusively in wireless and combined models (see "Connection type") - and only earbuds and earbuds (see above). Both headphones in such models are connected to each other either with a regular wire with a thickened part, or with a special horseshoe-shaped hoop (a separate “ear” is connected to each end of such a hoop with a wire). In any case, when worn, such a wire or hoop is located at the back of the user's neck, which provides additional convenience: headphones removed from the ears (or dropped out) do not fall to the ground, but remain hanging on the mount. And in some models, special magnets are also provided, with which you can “stick” the headphones taken out of your ears to each other, turning the entire structure into a ring - this further reduces the risk of dropping the device.

- Possibility of folding. The earphones can be folded compactly for storage and transport. Note that this feature is indicated only for overhead models (see above) - earbuds headphones and earbuds are quite portable in themselves, there is no need to provide a special folding design for them.

- Swivel bowls. A design feature found in over-ear headphones (see above). Rotary in this case means bowls that, in the working position, can be rotated at a certain angle around the vertical axis. This allows the headphones to further adapt to the dimensions and shape of the user's head - which, in turn, increases comfort, especially when worn for a long time. On the other hand, the swivel mount somewhat complicates the design of the headphones, increases its cost and somewhat reduces reliability.

- Glasses. Headphones in the form factor of glasses. The sound of such models is transmitted either by directional speakers built into the temples, or directly to the inner ear by conduction through the bones of the skull. In addition to music, bone conduction glasses provide audibility of what is happening around.

- Headband. Headbands with built-in earphones. In a similar format, children's's models of headbands with bright prints of cartoon characters and fairy-tale characters are produced, as well as headbands for fans of a sports lifestyle. Headphones in such models are usually made removable, which allows you to wash the headband.

The range of sound frequencies that headphones can reproduce.

The wider this range, the more fully the headphones reproduce the spectrum of sound frequencies, the lower the likelihood that too low or too high frequencies will be inaccessible. However, there are some nuances to consider here. First of all, let us remind you that the perceptual range of the human ear is on average from 16 Hz to 22 kHz, and for the complete picture it is enough for headphones to cover this range. However, modern models can significantly exceed these boundaries: in many devices the lower threshold does not exceed 15 Hz, or even 10 Hz, and the upper limit can reach 25 kHz, 30 kHz and even more. Such wide ranges in themselves do not provide practical advantages, but they usually indicate a high class of headphones, and are sometimes given only for advertising purposes.

The second important point is that a wide frequency range in itself is not a guarantee of good sound: sound quality also depends on a number of parameters, primarily the amplitude-frequency response of the headphones.

Rated headphone sensitivity. Technically, this is the volume at which they sound when a certain standard signal from the amplifier is connected to them. Thus, sensitivity is one of the parameters that determine the overall volume of the headphones: the higher it is, the louder the sound will be with the same input signal level and other things being equal. However, we must not forget that the volume level also depends on the resistance (impedance, see above); moreover, it is worth choosing “ears” for a specific device first by impedance, and only then by sensitivity. In this case, one parameter can be compensated for by another: for example, a model with high resistance and high sensitivity can work even on a relatively weak amplifier.

As for specific figures, headphones with indicators of 100 dB or less are designed mainly for use in a quiet environment (in some similar models, the sensitivity does not exceed 90 dB). For use on the street, in transport and other similar conditions, it is desirable to have more sensitive headphones — about 101 – 105 dB, or even 110 dB. And in some models, this figure can reach 116 – 120 dB. and even more.

It is also worth noting that this parameter is relevant only for a wired connection according to the analogue standard — for example, via a 3.5 mm mini-...jack. When using digital interfaces like USB and wireless channels like Bluetooth, the sound is processed in the built-in headphone converter, and if you plan to mainly use this kind of application, you can not pay much attention to sensitivity.

The sensitivity of the headphone's own microphone.

The more sensitive the microphone, the higher the signal level from it, at the same sound volume, and the better this model is suitable for picking up quiet sounds. Conversely, low sensitivity filters out background noise. At the same time, we note that these nuances are important mainly in professional work with sound. And for simple tasks like voice communication over the phone or via the Internet, sensitivity does not really matter: in headphones of this specialization, it is selected in such a way as to ensure that the microphone is guaranteed to work.

The presence of a noise reduction system in its own headphone microphone.

In accordance with the name, such a system is designed to eliminate extraneous noise - primarily during conversations. It is usually based on an electronic filter that passes the sound of a human voice and cuts off background sounds such as city noise, the rumble of wind in the microphone grille, etc. As a result, even in noisy environments, thanks to the noise reduction of the microphone, speech is clear and intelligible; True, the system inevitably introduces distortions into the final sound, but they are not critical in this case.

— ENC. ENC (Environment Noise Cancellation) technology significantly reduces ambient noise with directional microphones. It is used both in gaming devices so that gamers can easily communicate in voice chat, and in TWS earphone models so that you can comfortably talk on the phone in a noisy environment.

— cVc. Microphone noise reduction cVc (Clear Voice Capture) is an advanced technology that is found mainly in expensive headphone models. cVc algorithms effectively suppress echo and noise from the environment. Sound processing using this technology is carried out at several levels at once - the algorithm determines the reference signal-to-noise level, automatically adjusts speech to the desired volume level, applies adaptive equalizers to process the entire voice, as well as specialized filters to remove...low-frequency bubbling, sibilants and hissing.

The type of connector used to charge the built-in battery of the headphones, or more precisely, to connect an external charger. The role of such a device can be played by a network or car adapter, a power bank, or even a USB port of a PC or laptop (if there is an appropriate cable). At the same time, in true wireless models (there are with a leg, without a leg, with an ear mount and clips (Clip-on)), the "charger" cable is connected to a special docking station, where the "ears" are placed during charging (while the station itself usually has its own battery and can also work as an autonomous power bank). And in wireless and combined solutions of a more traditional design, the charging input is often located on the body of the headphones themselves. As for the connectors, the most common options are the following:

— microUSB. A smaller version of the USB connector, created for portable devices. It appeared quite a long time ago, but it has not lost its popularity in our time, and is used by the absolute majority of manufacturers.

— USB C. A miniature USB connector, positioned, among other things, as a potential successor to microUSB. Unlike its predecessor, it has a two-sided design, thanks to which the plug can be inserted into the socket from either...side. It is still relatively rare, but the situation is likely to change in the coming years.

— Lightning. Apple's proprietary connector. Like USB C, it has a two-sided design, and is somewhat more convenient and reliable, but the use of Lightning is limited to products from Apple itself and its Beats brand.

For full-size headphones, ear pads are often made of genuine leather, leatherette, textile, velor, leatherette, memory foam, as well as their combined variations. In the caste of in-ear headphones, completely different materials are used - the most common are silicone pads, which gently adapt to the individual structure of the auricle, and as an alternative to them, foam ear pads with a porous structure (so-called “sponges”) are offered. Here are some features of commonly used ear pad materials:

- Textiles. Fabric ear pads are usually found in budget headphone models, but sometimes they are also used in the premium segment. The tactile textile ear pads are pleasant to the touch, and they also allow air to pass through well. In terms of acoustic properties, these are completely neutral materials. Note that such ear pads can be made from various types of fabrics (for example, microfiber).

- Leatherette. Artificial leather substitutes are used in headphones of all price categories. In fact, the properties of this material depend on the specific type of leatherette: ear pads made of conventional eco-leather can have excellent “breathing” qualities, while low-grade leatherette often provokes increased sweating of the ears (especially in the hot season).

- Genuine Leather. Genuine leather is a premium product used in corresponding flagship-level...headphone models. Thick leather provides proper sound insulation and deep bass response. At the same time, your ears may sweat when using leather ear pads. To avoid increased sweating, the leather is often made perforated.

— Velor. The most delicate material to the touch with excellent sound-absorbing abilities. Velor ear pads provide good noise insulation, and headphones with them do not cause fatigue even after a long stay on the head. However, the material also has disadvantages: it gets dirty easily, attracts dust and pet hair, and wears out quickly.

- Alcantara. Ear pads made of artificial suede, which are as close as possible in properties and tactile sensations to velor products. However, Alcantara is easier to clean from dirt and lasts much longer. Alcantara ear pads are found in top-level headphones.

- Foam rubber. Foam ear pads are the prerogative of budget over-ear headphones. The fact is that this is a short-lived material that often requires replacement due to its low strength. Partially, special impregnations solve the problem, but foam rubber still retains its structure for a relatively short time.

- Fur. Quite a rare type of material for making ear pads. Headphones with characteristic fur ear pads perform a practical function - they warm the listener’s ears during the cold season.
