Very good 701 1

This is a great little headset.
The finish is good, and the sound is clean (no exaggeration bass or treble side)
The headphones are still small in size, so it might not be suitable in some (though the pads are comfortable).
Note that the sound is very "round", bass present. Next tastes, the equalizer has a good impact on the helmet,

The helmet insulates. Little outside noise is heard (type conversion).
In public transport, local area is attenuated.

Under Android device, the micro present work, the +/- keys, but also the center button to take the call

The price is very reasonable, and there is truly no competition at this price.
I would not say that this is an exceptional helmet has comparable tenors whose price is rather between 150 and 200. This last fact very good job, and is very well placed in its price range.
