Comparison Remax RB-T9 vs Remax RB-T7

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.

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.

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.

Replaceable silicone tips that come in a box with with the Bluetooth headset (see "Device").

Modern headsets are traditionally equipped with in-ear headphones or earbuds (see "Design"); both of them are held in the ear by a soft attachment, usually made of silicone. The size of such a tip may not be suitable for the user — in this case, the ability to change it to another, more convenient one, will be essential. Most often, there are three replaceable tip in the kit — large, regular and small.
