[CrackBerry Question]

I have bought a BlackBerry Classic 4 weeks ago. The first device was delivered with a broken screen. Two weeks ago I have arrived my replacement! I really love the phone and BB10 OS but there is one thing which is extremely bothering me: The sound quality while phone calls via headset! I tried to use it with the official headset which is delivered with the phone. When I am talking to someone I am hearing kind of an echo and everything sounds tinny. I can't even talk to someone because its so annoying! My first thought was that the headset is broken and if I use an other one the problem may be gone. Now I am using the headset of the iPhone 5 of my girlfriend. Now the sound is much way better but the microphone is still hypersensible! So some kind of echo remains and if the microphone of the headset just streaks my chest a little bit there is a incredible loud swoosh in my ears. I just want to know if someone else is experiencing the same problems or maybe there is somebody out there who knows a way to change settings for the microphone (but I don't believe there are settings like that in BB10 OS). Any ideas?

Exactly same problem here! Don't know if my phone is broken or its an software problem which can be fixed...
