Description

Bluetooth transmission is technically divided into v1.1 and v1.2 specifications, which are also different

when applied to Bluetooth headsets. v1.2 not only supports more stereo sound effects, but also has better

performance in terms of stability and effects, and is backward compatible with the v1.1 version. In addition,

Bluetooth-enabled mobile phones and headsets support two connection modes, "Handsfree" and "Headset".

Different models of headsets and mobile phones will not be successful.

Maintaining comfort is very important. After all, headphones that are too bulky can easily become a burden,

so sports headphones are generally as lightweight as possible, and they are also ergonomically designed to wear.

In summer, even if you exercise at night, it is easy to sweat profusely, and sweat can easily flow into

your ears, which will also affect the life of the headset. So sports headphones will do basic sweat and

waterproof measures.

If you don't wear it firmly, the earphones will easily fall off, which will only make exercise an unpleasant process.

Sports earphones are mostly designed with hanging ears, which can ensure that the earphones will not fall off

during intense exercise.
