I have used this headset for a couple of months (paired with a Cingular 8125), and it has been a real disappointment.The 'multipoint technology' is a joke. Trying to switch between my PC Bluetooth adapter and my phone just locks up both connections.Many times when I answer the phone, the other party hears a sharp growling sound for a second or two. Several different callers have complained about this -- not a good first impression if you're using this headset for business.Sound quality is no better than average. Callers notice wind noise about like most other headsets.I find the headset more comfortable than most, because its wraparound style stays on the ear better than others.
