Comparison Edifier WH950NB vs Soundcore Space Q45

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-sha...ped 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).

How to connect the cable to the headphones.

— One- sided. In such models, the wire is connected to only one earphone. This option is more comfortable and less prone to tangling, but the headphones must have a headband or neck mount so that there is somewhere to hide the wire that goes to the second ear.

— Bilateral. In such models, a wire is connected to each “ear” separately (the cable for this is usually “forked” closer to the headphones, and sometimes at the plug itself). This is the only option technically available for headphones without a headband or neckband. At the same time, overhead "ears" with a headband can also be made bilateral — in particular, high-end hi-fi and hi-end models, where such a design is provided in order to reduce the influence of wires on each other.

Range of wireless-capable headphones (see "Connection type").

When evaluating the range, it should be taken into account that this parameter is rather conditional and the actual range may differ slightly from the claimed one (usually in a smaller direction). So, when connecting via a radio channel, the range is indicated for perfect conditions — without interference and obstacles in the signal path. For Bluetooth models, the range also depends on the power of the Bluetooth module in the device to which the “ears” are connected. And the effectiveness of the IR channel may be reduced in hot weather or in bright sunlight. So when choosing according to this indicator, it's ok to take a certain margin.

On the other hand, there are two points worth noting. Firstly, in general, the specified range accurately describes the capabilities of the headphones, and it is quite possible to evaluate and compare different models with each other. Secondly, even in the most modest wireless “ears”, the communication range is about 8–10 m, 11–20 m is considered an average, and a fairly large number of devices can operate at distances of tens and even hundreds of metres. So paying attention to the range makes sense mainly in cases where you plan to move away from the signal source at a considerable distance — from 5 m or more — or listen to sound through walls.

The type of cable provided in the design or package of the headphones. Note that this parameter is relevant both for wired or combined models (see "Type of connection"), and for some wireless models - in particular, earbuds and in-ear headphones without attachment, where the wire connects one earphone to another.

- Round. Classic round wire - straight, without braid and other additional devices. It is inexpensive and in most cases quite practical, which is why it is found in most modern headphones. The disadvantage is that with a small thickness, the round wire tends to tangle; therefore, this option is considered not very convenient for compact headphones, such as in-ear or in-ear headphones (see "Design"), which often have to be carried in a pocket or bag.

- Flat. The main advantage of a flat cable is that it is not as tangled as a round one, and in which case it is much easier to unravel. This is especially important for earbuds and in-ear headphones, which are often rolled up for storage or portability. However, larger overhead models can also be equipped with a flat wire.

- Drawstring around the neck. A wire adapted in one way or another to be worn around the neck - for example, having the form of a loop from which two separate headphones depart. The main advantage of this design is the convenience for constant wear: if necess...ary, you can remove the headphones and leave them hanging on a cord, and then quickly put them back on. It is worth noting here that this option is found mainly among liners and in-ear models, for which the mentioned advantage is especially relevant.

- Round, braided. Round wire, supplemented with an outer braid - usually fabric. See above for more details on round wire. And the presence of a braid gives such a cable a number of advantages over the classic, in "bare" insulation. So, the wire turns out to be more durable, reliable and resistant to kinks and pressures, less confused, has a solid appearance, and in some models the braid also provides shielding from external interference. The reverse side of these advantages is the increased price.

- Spiral. Round cable, coiled in the form of a spring. The main advantages of spiral wire are that it practically does not tangle and can be noticeably stretched relative to its original length. The latter is very convenient if in the course of using the "ears" you have to change the distance to the signal source. The disadvantages of a spiral cable are bulkiness and relatively high cost. Therefore, it is often used in headphones of medium and top levels (including professional models).

- Round, braided. Cable in the form of two wires twisted into a spiral. Do not confuse this option with a spiral wire - in this case we are not talking about a spring. Such a cable is notable primarily for its unusual appearance; for greater originality, the wiring can be made multi-colored. It is also slightly more tangle-resistant than the classic round, although much depends on the thickness here. At the same time, individual wires can be noticeably thinner than a solid round wire, which somewhat reduces reliability.

- Zipper. Reversible wire (see "Cable entry"), in which the individual wires are hidden inside the halves of the zipper. The fastener does not cover the entire length of the cable, but usually takes up half, or even more. The headphones themselves with a similar wire most often belong to miniature varieties - in-ear or in-ear. Such models are very convenient in “packing” and “unpacking” for storage and carrying: by zipping up, you can connect two wires into one, and when you need the headphones again, you can unzip them by separating them. At the same time, the fastened zipper is very resistant to tangling. Yes, and this accessory looks quite unusual.

- In the form of a lace. A wire that looks like a lace - like tech used in shoes or clothing. Do not confuse such a cable with a cord around your neck (see above) - in this case, we mean not the way the wire is worn, but a specific type of braid. Such a wire is comparable in width to a flat wire, due to which it resists tangling well. However, the main advantage of this option is still the original appearance: “laces” are often made in bright colors, can be painted in several colors, complemented by a pattern, etc.

A special game mode in wireless headphones that minimizes the delay in transmitting an audio track from a connected source. Low Input Lag) provides the ability to quickly respond to what is happening in virtual battles and prevents the picture from being out of sync with the sound. At the same time, when you activate the game mode, wireless headphones will be discharged faster.

Sound delay in wireless headphones is a natural process caused by the specifics of audio data transmission over Bluetooth. It can be either almost imperceptible or clearly interfere with comfortable gameplay or watching video content. This paragraph provides the declared sound delay time in milliseconds, which is written in the technical specifications for a particular headphone model.

Impedance refers to the headphone's nominal resistance to AC current, such as an audio signal.

Other things being equal, a higher impedance reduces distortion, but requires a more powerful amplifier — otherwise the headphones simply will not be able to produce sufficient volume. Thus, the choice of resistance depends primarily on which signal source you plan to connect the "ears". So, for a portable gadget (smartphone, pocket player), an indicator of 16 ohms or less is considered optimal, 17 – 32 ohms is not bad. Higher values — 33 – 64 ohms and 65 – 96 ohms — will require quite powerful amplifiers, like those used in computers and televisions. And models with a resistance of 96 – 250 ohms and above are designed mainly for Hi-End audio equipment and professional use; for such cases, detailed recommendations for selection can be found in special sources.

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 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 remo...ve low-frequency bubbling, sibilants and hissing.
