Comparison HyperX Cloud Stinger 2 Core vs Razer Kraken X Lite

The design of the plug provided in the headphones. This parameter is relevant primarily for models with a mini-Jack interface (see "Connection") — the rest of the plugs are made straight in most cases, exceptions are extremely rare.

— Direct. The traditional, most simple and unpretentious option is plugs that do not have any bends. Usually, they are compatible without restrictions with stationary audio equipment, PCs, laptops, etc. But for smartphones and other portable gadgets, this option is not always optimal — it all depends on how the gadget is located in your pocket or case. In some cases — for example, when carrying a smartphone in a regular pants pocket — such a wire can be strongly bent around the plug, which quickly becomes unusable; in such cases it is worth paying attention to L-shaped or curved plugs (see below).

— L-shaped. Plugs angled at 90° in the shape of the letter L. Designed primarily for use with smartphones and other handheld devices: such devices, when worn, can be positioned in such a way that a bent plug is more convenient than a straight one. However, the L-shaped design may also be the best choice for stationary equipment, where the headphone wire approaches the connector at a right angle — for example, this situation is often found in computers and laptops.

— At an angle of 45°. A variation of the L-shaped plug...described above, bent not at a straight line, but at a smaller angle (not necessarily exactly 45 °). It is also designed primarily for pocket equipment, and with such an application, such plugs are considered even more convenient and reliable than traditional L-shaped ones. But for stationary devices, it hardly makes sense to specifically look for a model with a similar connector (although such an application is technically quite possible).

The length of the cable supplied with the headphones with the appropriate connectivity.

The optimal cable length depends on the planned format of the "ears". So, for pocket gadgets, 1 metre or less is often enough, for a computer it is already desirable to have a wire for 1 – 2 m, and preferably 2 – 3 m. And models with a longer cable length — 3 – 5 m or even more — are mainly designed for specific tasks, such as connecting to a TV or using in recording studios.

Recall that in some models the cable is removable (see below) and can be replaced if necessary with a longer or shorter one. Also note that there are extension cables that allow you to increase the length of the main wire; such a cable may even be included in the delivery, this point (and the length of the additional cable) is usually specified in the notes.

The audio format supported by the headphones.

— Stereo. Two-channel sound that allows you to create a surround sound effect to a certain extent (due to the difference in the right and left channels). The design of the headphones (two speakers, one for each ear) was originally “sharpened” specifically for stereo, so the vast majority of models support this particular sound format.

— Mono. Single-channel sound that does not create a surround effect. This marking means that this model is equipped with one earpiece ; At the same time, there are two types of such devices on the market. The first is headphones that initially have only one cup and are designed for situations where the second ear needs to be left open (for example, to work on the phone in the office). The second is true wireless devices (see Cable Type), sold singly to replace a lost earphone from the original pair.

— 5.1. Originally, 5.1 was designed to create surround sound that can come from any direction ("surround"). It assumes the presence of 5 main channels (centre, front left / right, rear left / right) and one bass. In headphones, the effect of this sound is achieved through the use of several speakers in each cup. Such models are very convenient when watching movies with multi-channel sound, as well as in games — they provide a powerful immersive effect. On the other hand, such headphones are not cheap, and besides, they require a specifi...c connection method (for example, via USB).

— 5.1 (virtual). Models with support for 5.1 surround sound (see above), in which the surround effect is achieved not due to the number of speakers, but due to special sound processing technologies. This somewhat reduces the accuracy compared to the "non-virtual" multi-channel, but it can significantly reduce the cost and weight of the headphones. However, there can also be several speakers in such models — for example, for separation by frequency.

— 7.1. The 7.1 format is the multi-channel 5.1 described above, supplemented by two more main channels. The localization of these channels depends on the specific variety of 7.1, but anyway they enhance the effect of volume. On the other hand, full support for this format significantly affects the dimensions, weight and price of the headphones, and content with 7.1 sound is produced much less than 5.1.

— 7.1 (virtual). A “virtual” version of the 7.1 format described above, in which the effect of surround sound is provided primarily through special signal processing, and not due to the presence of separate emitters for each channel. Similar to virtual 5.1, this format of operation somewhat reduces the reliability of the sound, but this difference is often imperceptible, and the headphones themselves turn out to be simpler and more inexpensive. Therefore, most modern 7.1 models support the virtual format of this sound.

— 9.1 (virtual). Further development of the idea of multi-channel sound: 5 channels, as in 5.1 (see above), supplemented by 4 more channels for more accurate localization of audible sound. As in other virtual formats, volume in this case is provided by special processing algorithms.

It is worth remembering that the actual sound will depend not only on the headphones, but also on the signal source: for example, a mono recording even in 9.1 “ears” will not become voluminous.

— 3D sound. Surround sound with the localization of sound sources in three-dimensional space allows you to deeply plunge into the atmosphere of films or immerse yourself in a virtual game world. The mechanics of spatial 3D-sound provides localization of sound sources around the listener and in the vertical scan plane. Algorithms for implementing 3D sound in headphones differ in terms of software and hardware support, but all of them are aimed at achieving the effect of realism of what is happening. Surround sound has long been the standard for movies, and in recent years, 3D sound has become increasingly common in games and music tracks.

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 coefficient of harmonic distortion produced by this model of headphones.

This parameter determines the amount of non-linear distortion introduced by the headphones into the reproduced sound. The lower it is, the less such distortions, the cleaner and closer to the original sound is. So, an indicator of 1% or more can be considered tolerable at best, from 0.5% to 1% — good, less than 0.5% — excellent (such indicators are acceptable even for monitor headphones), and less than 0.1% — almost perfect.

Note that a low harmonic coefficient in itself does not guarantee high-quality sound — a lot depends on other features of the headphones, primarily the frequency response.

The range of audio frequencies that the headphone's own microphone can normally "hear".

Theoretically, the wider this range, the more advanced and high-quality the microphone is, the closer the sound transmitted by it is to the real one. In fact, extensive frequency coverage is not always required. So, the working range of the human ear is about 16 – 22,000 Hz, and even then not everyone hears its upper part. And human speech usually covers frequencies from 500 Hz to 2 kHz, at least this range is considered quite sufficient for its transmission. So if you need a microphone for simple tasks like voice communication on the Internet or game chat, you can not pay much attention to the frequency range: even in the most modest models, it is more than sufficient for normal speech transmission.

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.
