AFAIK there are none.
The absolute best BT headsets for sound quality are:
Sony HBH-300 (an antique now, but had tremendous SQ)
Plantronics Voyager 510 (cheap, $40-50)
Sennheiser BW900 (big and expensive, but it works with wired phones too)
Others like the Blue Ant Z9, Motorola h15, Jawbone 1 and 2 all offer great SQ for their size, but sacrifice some sound quality for a small and compact size.
