Comparison Jabra Motion UC vs Jabra Storm

The maximum distance from the headset to the signal source at which it can be used normally.

Note that this indicator is stated for optimal conditions; the actual communication range is often lower than the claimed one due to obstacles in the signal path and extraneous interference. However, the minimum range for Bluetooth accessories is actually 10 m, which in fact, usually, gives at least 5 – 6 m — and this is quite enough for comfortable use. There are also more "long-range" solutions, with a range of up to 50 m or even more. However, it is worth remembering that Bluetooth is a two-way communication, and the range claimed in the specs must be supported not only by the headset itself, but also by the device with which it is used.

Also note that a long range means not only the ability to communicate over a long distance, but also a good ability to work through obstacles such as thick walls. Therefore, a powerful Bluetooth device may be necessary even at a short distance — if there are obstacles at this distance.

The diameter of the speaker installed in the device. In this case, we can talk about both the actual speaker installed in the speakerphone, and the headphone emitter that the Bluetooth headset is equipped with (see "Device"). Accordingly, the meaning of this spec in both cases will be different.

In general, the large size of the speaker, on the one hand, allows you to achieve better volume and more reliable transmission of low frequencies; on the other hand, it requires more space for installation. This is especially true for headsets, since the types of headphones used in them (see "Design") have severe size restrictions: earbuds are made no larger than 15 mm, in-ear solutions have a diameter of less than 10 mm (only the headphones of the same type may be compared by size with each other). Note that an earpiece that is too large may be uncomfortable, or even not fit in the ear at all. So the perfect option is to try on the headset before buying.

In turn, speakerphones usually use speakers with a diameter of about 50 mm — this size is considered the best compromise between overall efficiency and compactness.

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.

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.
