Headphones come with all original packaging and accessories. These headphones were sent out to SoundID on day one to get them individually calibrated (back when they allowed you to ship your own headphones for individual calibration). So if you are a user of the SoundID software and want a flat frequency response specific to this headphone, then this will be very helpful and save money by not needing to calibrate it. All you would have to do is enter "AB529H" in the calibration profile in the SoundID software and it will be ready to go. This is very great for those who are mixing/mastering engineers.

NOTE: There are ZERO problems with the headphones itself (including the drivers)....HOWEVER, just like you see in the pictures, one set of cables on ONLY ONE SIDE has electric tape on it due to the cable having its outer rubber part torn by about 2 inches from a headphone holder I owned that had an end that was kind of sharp and the cable got caught on it between the holder and the wall. I put extra electric tape going down just to be safe so that the rubber doesn’t tear downward some more. The wire and internals of the cable are 100% fine though and there are ZERO issues with audio playback. This is the only set of cables I used for the headphones in its entirety and the other extra cables in the box have never been used. I did take this part into consideration for the pricing.
