First time post, so take it easy on the newbie.

Anyway, I bought my wife a Motorola H670 bluetooth headset for Christmas. The sound quality and functionality worked perfectly, however she has the tiniest ears known to man. Therefore, even the smallest of the three clips that came with the model would not fit tight enough on her ear. So... back to the store that one went.
Next, she went and bought an LG HBM-730, simply because it had this wire that would wrap around your ear and it is an in-ear design. She seems to love it, however when I talk to her (or anyone else does) when she uses the headset, I can hear the background noise so much louder than her that it is extremely annoying.

It's usually one of my two boys screaming about their brother hitting them or something of that nature.
So I guess my question is: Is there a bluetooth headset out there for around $50 or so that has good sound quality and would work for someone with an ear the size of a half dollar. Thanks.
