Bluetooth In-Call Volume

[SpecialAgentSicari]

I had one of those and it sounded really tinny, so I gave it to my dad. I am convinced that it is the phone. I used to use a Jabta bt350 and my Uncle has the same headset hooked up to a Sanyo phone. And that thing is super loud, I can hear what people are saying with it stuck in his ear. On the other hand I had a really hard time hearing out of mine.
