I finally did what I should have done in the first place and replace it with Sennheisers version. Im not sure if Im just getting old, or was too attached to my 4 year old Havaianas that took me travelling around the world, which sadly broke beyond repair. Assembly dowels did not seat properly causing them to perforate top shelf of unit. I have now been using them for about 1 month. Buyer beware, you only get a little, short bang for your hard earned buck shot with these. With that said, it doesnt look like it was used for long as it is a white controller and there are no noticeable stains from use. They are sturdy and have great sound. I had very realistic expectations and in which areas I expected to hear improvements. My thumbs slip right off these light, but obnoxiously large and smooth thumb ?pads. The sound stage is larger and the clarity is better (in my opinion).
