A year after the Sonys came out they made the NCH 700, which beat the sonys in microphone performance.

I could even chew or wash my hands or sit in a noisy cafe without the other people in the call hearing it.

The audio quality might be better with the Sonys, but at least they answered to the Sonys in a timely way. I had no bad experience with those yet and used them for almost a year already. No idea about customer support.

I know this thread is about the QC model, but I wanted to throw this in here. IMHO bose is not behind at all.
