Connection

Mini-Jack (3.5 mm). Mini-Jack is one of the most popular wired connectors. However, it is not used in Bluetooth headsets, and it is extremely rare in other specialized accessories and predominantly is an auxiliary feature. So, in speakerphones, mini-Jack is usually responsible for connecting several devices to each other, and in car kits, for outputting sound to the radio or standard car acoustics. Note that in this case, the headphone jack is not considered a 3.5 mm jack, although it is most often performed in this format.

— USB A. The classic USB A computer connector, which is gradually being replaced by the USB-C connector. The meaning and application of this connection depends on the type of device. So, USB in speakerphones is a standard port for wired connection — both to computers and to specialized communication systems. And in Bluetooth headsets, this means that it is equipped with a USB adapter for connecting to a PC without a Bluetooth module.

— USB-C. A port similar in purpose to the one described above, but with a different, more modern, symmetrical shape that does not require specific connection, and correspondingly increased speeds.

Bluetooth. Nowadays, Bluetooth is actually the standard interface for wirelessly connecting headsets and other audio accessories to gadgets. This technology is not only well suited for...audio transmission, but can also be used for additional functions such as remote control. Features vary by version, the latest being Bluetooth v5. The communication range in this case can reach 10 m, and built-in Bluetooth modules are available in all modern smartphones, most phones, tablets and laptops, they can also be used in PCs and many other types of gadgets.

Battery capacity

The capacity of the battery installed in the device (see "Power").

Theoretically, a higher battery capacity allows you to work longer on one charge. At the same time, the actual battery life will also depend on the power consumption of the device, and it is determined by a number of technical specs. Therefore, it is better to evaluate battery life not by battery capacity, but by directly claimed operating time (see below). It makes sense to use this parameter if the operating time is not specified; at the same time, it makes sense to make conclusions only if devices similar in specs differ in capacity — for example, 60 and 110 mAh.

Battery life

Time of operation of the self-powered device (see "Power") on one battery charge.

Usually, the battery life in the talk mode is meant, when the device consumes the most energy. In headsets with high-capacity batteries, this battery life can be 9 hours or more. However, talking for several hours without pauses is almost impossible, so in fact the operating time is noticeably longer than in the specifications. So, a headset with an operating time of the same 9 hours is most likely quite enough for a 12-hour work shift, even if you have to constantly make calls through it; and if we are talking about only 5 – 6 calls per day, then the charge is guaranteed to last for several days, or even a week. At the same time, the difference in the claimed operating time is usually quite consistent with the difference in actual battery life, and it is quite possible to compare the real capabilities of different models by it.

Charging time

The time it takes to fully charge the battery in powered headsets.

In this case, we mean the time it takes to charge the battery from 0 to 100% when using a standard charger (or a third-party charger with identical specs). Accordingly, this indicator may differ from the stated one, depending on the specifics of the situation. However, it is quite possible to evaluate different models using it, compare them with each other and choose a headset with fast charging.

We also note that increasing the battery capacity inevitably implies an increase in charging time. To compensate for this point, special fast charging technologies can be used. However, they affect the cost and require the use of specialized chargers.
