- Perfect product for my use, ie for switching throughout the day between the mobile phone and Lync or Skype communications. A button allows you to switch quickly from one to the other - he finds the connection in record time. - In my case no movement away from my PC or my laptop so no comment on the scope or on autonomy, because I can easily connect it to recharge while continuing to use it. - The sound is excellent, both for me as my interlocutors according to their comments. - Installation / PC connection extremely fast and without any manipulation to do. Connecting to mobile by bluetooth classic procedure and without any worry. - Finally, the headset is quite comfortable.
