Scala
On my second Scala set.
After the Teamset started to give problems I tried an Interfone set which caused me problems as the speakers and microphone were too large for my X-Lite 701. For that reason and the fact that the LH speaker didn't work and the Bluetooth unit kept falling from its holder meant that I returned it
Now on a Scala Q2 (I think) which is very good and much better than the Teamset as it switches on easier and is louder with a MP3 connection
I'm not too fussed about music quality as it is mainly used for communications with the wife and sat nav
