The Aiva's were bought new, then burned in for 60 hours using fellow member PelPix's "44.1kHz 16-bit" pink noise WAV file. Then I listened to them for about an hour or less, and decided the highs were a little too sibilant for my taste (I think it's likely my weak dac/amp, since they otherwise sound amazing).
All original accessories, cables, and boxing are included. I'm also including a sealed, new set of spare pads (the newer ones, not the older versions). I thought the original pads that came with the headphones were asymmetrical left-right wise, so MusicTeck sent me a new pair, which I haven't opened yet.
