Excellent! We have a collection of headphones including Audio Tech, Beats (yes, Beats :), Bose, Monster, Sennheiser, Sivga, Sony, Tate and Bauer and more. We used to buy Bluetooth receivers from Maceton (really good ones) but they've disappeared from Amazon :(So we decided to try this receiver which is a bit bigger than Maceton and so far so good. The extra bass boost option is really cool, we always use it on. If it doesn't break, burn out, stop working or something like that, we'll buy another of the same model. Update 17 August: still good, no problems at all. We've ordered another unit :) Airfrex Wireless Bluetooth Receiver Adapter for Bose QuietComfort 25 (QC25) Headphones, Bose QC25 (QuietComfort 25) Replacement Cable/Cable Adapter
