Good tangent. Speaker loud. Sound without wheezes and impurities. There is something to compare with. The first tangent bought a cheap one, thought it would come out, but ....

Everything is fine. The sound is excellent, everything is heard, without foreign noise. It approached the "domestic" walkie-talkie Altavia 301 m.

On the speaker from below there is a jack for connecting the earphone. Closed rubber plug. In the pictures, the size is not very visible.

The headset came to Kirov for a week! Quality is normal! In the rain has not yet checked!))) bought for quangsheng UV 2 Plus! Recommend!

Tangent is good, done qualitatively. The sound is good, the only negative is that the button works on one channel.
