Only dislike is the bottom containers dont sit flush across the horizontal frame, so they sit at an angle; which looks a little annoying. When situated properly, the 16mm drivers do their thing. Once broken in they’re comfortable as hell and I love them. This product is miracle. ** Update : I tried with my bluetooth earphones, and the whole problem is gone. It arrived and only includes 2 x 24" rails. Years of dealing with Displaylink drivers on those docks taught me it isnt woth the time. Im wondering at this $33. these are too high in the heel of the shoe. Lieferung erfolgte sogar schneller als geplant.
