Very disappointed 1 8

If the announced features are there, the quality did not:
- Volume of the lower speaker as his free hand on my HTC ONE (M7)
- Nasal microphone,
- Sizzling with each change of function
- If the FM channel is automatically found, the announcement of it (in French, other languages ​​not verified) is quite visionary: 102.9 for the announcement that is made is 10-2. 90 and voice is nasal, it surprises!

in positive, FM connection when it's a free and understood its frequency is of good quality.
For too few positive point for a device equivalent to a shot Jabra Cruiser2 a much higher quality.
I returned the unit and are asked refund. Avantree is reviewing its copy.
