I just bought the Bose 700's and I had mostly good thoughts. Until I noticed while walking with the headphones I could hear a clanking noise with every step, and after inspection, I noticed that the headband would hit against the earcup making a really annoying rattling noise. This is is so incredibly infuriating. I paid $530 for these headphones plus protection plan and I can't even enjoy music while walking around.
