I have a Bose A20 headset that was hardly used in great condition. I'm asking $650 for it. They'll be a great deal for someone who needs an awesome headset.
This is a great headset model. I finally took the plunge after repeated offers from Bose. The engine sounded much quieter compared to my Lightspeed 3Gs (which also had ANR).
I know this Thread is old but I have I Used pair of Bose A20 and 4 Used pair of Bose X. They are all functional with bags. I am Open to all offers. They are just collecting dust.
