Can someone recommend a bluetooth headset that
1) CAN BLOCK BACKGROUND NOISES
2) Clear conversation on both ends.
3) Long distant range from phone to BT headset.
Those are the 3 features I am looking for.
This is my first phone with bluetooth technology. So I read and read about the bluetooth headsets and decided to buy a
Plantronics Discovery 645, (refer as PD645 from now on) with the latest DSP technology that's suppose to block out background noises. I have to say that DSP is crap.
I've conducted the following tests:
1) Talking on PD645 with a fan blowing towards me with medium wind (distance is about 3 inches).
Result: Major loud wind static, on both ends (I can hear it and the other person can hear it).
2) Music turned on from my Logitech z2200 speakers at the level that I usually listen to. Compare with conversation through (a) PD645, (b) Speaker phone and (c) the handset itself.
Result: Talking on PD645 tends to have the loudest background noise, even more so than the speakerphone! That's crazy

! Of course the winner of this test was talking on the handset itself (least background noise).
3) See how far I can take my PD645 from the PPC6700.
Result: I get statics with just about 5 feet!! If you keep going it's be dead by the time you reach 10 feet. But it's weird how it gets statics with 5 feet range (no obstacle between phone and PD645), it becomes clear when I am about 15 feet away a wall is between the phone and PD645.
Overall, very unsatisfied. This being my first BT headset, and cost a lot of money, it sucks very very much.
But on the plus side, it is VERY comfortable and lightweight. Works great in quiet environment in terms of sound quality. It is also very loud to me. But the negatives definitely outweights the positives.
So hopefully someone can give me some suggests on the 3 features I am looking for above.
