My Bose X is showing signs of wanting to retire. Had it since 2006 and it's been in for repairs on three occasions (twice out of warranty). But I think it's time to update.
I've used the A20 with my previous job quite a bit. Seems to be quite a good headset, other than one or two having the very uncomfortable squealing occasionally.
No experience with the Zulu brand. But from the reviews I've read, they seem to be more susceptible to the squealing.
Question is; Does anyone know of any rumors of Bose releasing a new Headset any time soon? The A20s have been around for a few years now. All be it, with a few updates along the way.
