No issues with install or the Bios recognizing the full memory count. After reading others reviews, I opted to order a half size up. If you want this to hang a lot of heavy coats I would NOT suggest this. I got the plain wooden version but I believe theres also a stained wood version available as well. It slightly helps. -The infinite button is for connecting other JBL speakers. Both microphones are fine but to simply plug this little mic and just start reading is incredible. On well-produced records that are in good condition, this combination produced acceptable results - for approximately the first 2/3 of such a record, then I started experiencing rather noticeable inner-groove distortion. The noise cancellation feature is not completely guaranteed, which one would expect at this price level, but there is very little background noise that emanates through. Ive only worn them a couple times, one day for a few hours shopping and theyre very comfortable right away.
