Rating : - Probably incompatable with my phone
The vendor tried to make it right by sending another pair, so that is why the 3 stars. However I could not make these work with my Nokia 6555. I also tried an HS-42 which exhibited the same problem, nothing in the left ear. To satisfy myself it was not a bad phone, I tried an 2.5/3.5 adaptor and regular ear buds work fine.

As someone pointed out they kind of work if you put them in halfway and then the volume is low. I am next going to try the HS-40s. Some web sites variously list these headsets as compatable, some do not.

I don't know why the industry seems so incompetent in provding proper headsets. Maybe with the new hands free laws this will change. Jeeesh.
