I had been loving my HTC One until I started a new job and had to use a bluetooth headset for calls...had Plantronics Backbeat Go, but people complained of the sound quality on the calls so I did some research and bought a Jawbone ERA. The Jawbone was super comfortable but the sound quality on both ends was terrible, so I returned it. Got the replacement...but still terrible. So my company bought me a Plantronics Voyager Legend UC. This thing is crystal clear used via the USB dongle with Lync, and crystal clear paired via Bluetooth to my old iPhone 4....but terrible with the HTC One. I've done a lot of forum post reading and there is some speculation that this will be solved when they roll out Android 4.3, but HTC says they have no plan to do this in Australia at present, so I'm stuck holding my phone to my head getting brain cancer all day.
What really annoyed me was the support person sitting in India for HTC told me to provide the "Bluetooth Profile" for the headset or she couldn't help me. When I asked her to be more specific (what is a bluetooth profile) she just kept saying to ask the manufacturer for the bluetooth profile, otherwise she couldn't solve my problem.
Suggestions?
