Hello, I decided after many compare to the Sony SBH20. The part is the sound really great. The headset has already been described and praised by many, so one thing that has not been so singled out: The great thing about this headset is also the remote control: you can at the control unit, which is attached to the clothing with a clip, the music up - and jump down. I have a Nokia Lumia 920 and the connection worked right away. Ps .: I can confirm the good assessments fully.
