Comparison Realme Buds T300 vs Xiaomi Redmi Buds 5

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.

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.

The search function will come in handy if the headphones are missing somewhere and you cannot find them. It is implemented, as a rule, through a smartphone application. In the programme interface, just press the search button and both headphones will immediately start emitting a loud signal. The second option for implementing the headphone search function is to track the last location of the headphones according to GPS satellites.

The capacity of the battery installed in the headphones of the corresponding design (see "Power").

Theoretically, a higher capacity allows to achieve greater battery life, but in fact, the operating time also depends on the power consumption of the headphones — and it can be very different, depending on the characteristics and design features. So this parameter is secondary, and when choosing it is worth paying attention not so much to the battery capacity, but to the directly claimed operating time (see below).

The capacity of the battery installed in the case (case) for headphones.

This parameter is relevant only for true wireless models (see "Cable type"). Recall that these headphones are charged from a case, which is usually equipped with its own battery and actually works in standalone power bank mode. Knowing the capacity of the battery in the case and in the headphones, you can estimate how many charges of the “ears” will last for one charge of the case. However, it should be taken into account that in the process of charging the headphones, part of the energy is inevitably spent on third-party losses, and the effective capacity of the case turns out to be somewhere 1.6 times less than the claimed one. This is the starting point for calculations: for example, a 300 mAh case will actually be able to transfer 300 / 1.6 = 187 mAh of energy to the headphones, and 30 mAh “ears” from such a battery can be fully charged about 6 times (187 / 30 ≈ 6).

The maximum battery life of headphones on one full charge of the battery or replaceable batteries in talk mode. A long working time will be relevant for those who expect to regularly conduct long telephone conversations. Note that in talk mode, autonomy may be lower than when listening to music, since the use of microphones and clear voice transmission algorithms puts an additional burden on the hardware of the headphones.

How long does the active noise canceling headphones (see above) last on a single battery charge (or a set of batteries) when noise canceling is not used.

This function is quite “gluttonous” in terms of battery consumption, up to half of the total energy consumed by the headphones can go to its work. Thus, models with noise reduction can indicate both overall battery life (see "Operating time"), and battery life with the noise reduction turned off.

The function reduces the charging time of the headphones compared to the duration of the standard procedure. For this, increased voltage and / or current strength is used, as well as a special "smart" process control. The capabilities and features of fast charging may vary depending on the specific implementation of the technology. Most often, accelerated charging implies the possibility of literally 5-10 minutes. extend the battery life of the headphones in the accompanying charging case by at least one hour of additional playback.

The headphones have special protection against moisture and dust; also, this clause may specify the level of such protection according to the IP standard.

Not all waterproof headphones allow complete immersion in water, but in this case this is usually not required — water protection is mainly intended for safe operation in the rain (or during sports activities when the user sweats a lot). But the specific degree of such protection in different models can vary markedly, and here it is most convenient to evaluate it by IP marking. This marking consists of the letters IP and two numbers; moisture resistance is described by the second, last digit, and in modern headphones you can find the following options:

— 2. Protection against vertical drops of water in the working position and when the device deviates up to 15 ° from this position. The minimum indicator that allows us to talk about resistance to rain (however, without strong winds).
— 3. Protection against splashes falling vertically or at an angle up to 60° from the vertical. Provides resistance to moderate rain and strong winds.
— 4. Splash proof from any direction. With such headphones, rain of medium intensity is not terrible, regardless of the strength of the wind.
— 5. Protected against water jets from any direction. Allows you to transfer already a combination of stro...ng wind with a downpour.
— 6. Protection against strong water jets. It is considered the minimum level that allows you to swim safely (with your head above the surface of the water) wearing headphones.
— 7. Possibility of short-term (less than half an hour) immersion under water to a shallow depth (less than 1 m); continuous operation in immersed mode is not expected. In such headphones, you can no longer only swim, but also dive under water to a shallow depth (plunge with your head), but they are not suitable for full-fledged diving.
— 8. The highest level of water protection actually found in modern headphones (although theoretically there is a higher level, level 9). Allows long-term (more than 30 minutes) immersion under water to a depth of 1 m or more, and even permanent work in a submerged position. And although the latter is not particularly relevant for headphones, however, this degree of protection makes it possible to swim and even dive safely. However, note that specific restrictions on use in such headphones may be different, they must be clarified according to the instructions.

As for protection against dust (it is indicated by the first digit in the IP marking), its level in modern “ears” is indicated mainly in cases where it corresponds to level 4 (protection against objects 1 mm thick or more), 5 (allowed a small amount of dust that does not affect the operation of the device) or 6 (complete protection against dust). Also note that this number can be replaced by the letter "X" — for example, IPX7; this means that no official dust certification has been carried out for this model. However, this resistance in many cases can be assessed by the degree of protection against moisture: for example, devices with a moisture resistance of 7 or 8, by definition, do not let water through — which means that they are also not afraid of dust.
