Sound Quality BT Headset Expensive/Inexpensive?

[KDmospd]

I normally don't post but whatever... I didn't find a thread in the search and if there's one my bad.

I'm looking to purchase a Bluetooth headset today but I just don't want style/flashiness. I want the best headset that'll filter out the background noise, not just from my side but the other end of the call too. I've read that the Jawbone was pretty effective but I would also like to find out some inexpensive quality pieces too for my consideration. I'm sure everyone has their own preference but that's exactly what I'm trying to take into consideration. Any real suggestions are more than welcomed; any flaming or egangster acts will be ignored.

In addition, have anyone ever purchased a BT headset from Amazon.com? I saw the Motorola H710, H700 for like $26. I did a Google search and I haven't found anywhere that states if those pieces are good quality or not. I know some are used, some are listed as new for $26 and $43. Anyone know the deal with those, are they worth saving the extra money?
