I'm thrilled!
I have both the headphones with my phone (Nexus 5) and coupled with my notebook. Connect to two devices at the same time is possible. Over the phone I listen to music on the laptop I run Skype. Once a call on Skype comes, goes the Music Player on the phone paused and the call from Skype comes into the headset.
For listening to music on the notebook's Bluetooth adapter is too old in the notebook. The music comes from there not in HiFi. For this I need a BT set 4 USB Adapter me probably.
The conversation on Skype was very pleasant, the ambient noise in the office was almost completely hidden at least for me. Whether my interlocutor was disturbed about it, I have not asked.
When I got the headphones after talking declined, I was amazed at how loud it was in office.
The headphones may perhaps be a little too expensive for this use, but how much is worth a rest?
