I bought the headset for my phone Sony Ericsson Vivaz smartphone. It really is very stable, the clip keeps top of jackets and T-Shits. The connection quality at the mobile phone is awesome. Dropouts, I had none at all. The supplied headphones are to me personally but much too quiet. I mainly listen to audio books and car noise or other loud noises I can hardly understand what. Have them replaced by Sennheiser and now I have the volume even turn down. Operation is super simple, make calls the work class, a call comes in, the music is automatically interrupted and after the call the music is playing now on. The participant understands me clearly and I him. The battery life could be a little longer, I hear so often about 8 hours a day and not quite grabs it unfortunately.
Otherwise, I can only say a very great device for less money, I would buy myself again. 1 point I am giving deduction, because the headphones.
