Although the unit makes a good impression optically, but also their interactions via
NFC works well. But the sound is simply washed out.
With the externally supplied headphones it sounds quite good -in SUM, but with Koss or other (not in-ear headphones)
sounds of sound washed out, via "catch" on a car radio or a stereo system and not at all well.
To want to leave the function left. One can use any key
paging settle. (Ex .: cries Mrs. XYZ at, etc.) you can just dial the last number.
In the old headset that went.
Value so rather not so good.
Conclusion: As pretty much all Bluetooth headsets. Poor sound quality.
Possibly Does that sound new Nokia headset better. Time try ...
