What is the best sounding wired cell phone headset that i can buy?

I am hoping to spend under $40.  I want something with a very high
quality mic and noise cancelation.  I need to use it in my car where
noise is an issue.

It is for a blackberry 7230, which uses a stnadard sub-mini walkman
type jack. i have been using the jabra softgell one which i find on
ebay for $6 or at stores for $25, but people say they can't hear me
well when i am driving.

Are there some reviews out there of high quality wired headsets?

Also, it would be a bonus (i would add a $5 tip) if you also add
reviews/a recommendation on a great bluetooth headset with noise
reduction.  it would have to have a basestation since my blackberry
7230 does not have bluetooth.

thanx in advnce,

I have always found Plantronics products to be excellent. They make a
wide range of wired phone headsets from basic, under-$20 units to some
that cost several hundred dollars. I use one that cost about $22 at
"Orifice Despot" and it is fine.

As they boast on their packaging, they made the headsets for the
Apollo program, or something like that.
