Very Good to Excellent Condition. I've had it for one year, bought on Amazon last January.
Lightly used at home and 4 plane trips. This is a great wireless (apt-x bluetooth) set of cans with vg noise cancellation. I haven't needed either feature as much as I expected and I'd rather get a better sounding set of cans and give up the noise cancelling / bluetooth for better sound w/o Sennheiser veil. I prefer a more forward - Grado-esque attack.
All original accesories intact including airplane adapter, 3.5 mm to 1/4" phone plug adapter, 3.5 mm to 2.5 mm to connect headphone, usb A to usb micro cord and carrying case.
Battery lasts 15-20 hours. These have not been abused.
Excellent bluetooth connection up to 2 devices, when paired and in range it connects to both devices quickly upon power on.
If you're listening to music from your computer and it's also connected to your phone, it will interrupt your music when you get a call, and depending on your phone's settings it can also tell you if you have text, email, etc.
Touch commands on right ear back work well.
I have no feedback so I prefer to trade with someone who does so I can send first without worry.
If you are interested I may take something else in trade, let me know what you have to offer.
