I bought the gold first, and I?ve just bought the silver. They fit (easy to attach too) perfectly on the earphones with no slippage off them. Plus, its not full proof noise cancellation. Buenos materiales. These are so amazing at first I didnt want to order them but I didnt want to pay $200 for another brand, I am so glad I ordered these, they fit in my ear with falling out or looking crazy plus the battery life on them are awesome. These look cheap and are very wide. Very confortable. The 25 model was fantastic, lasted me over a year and felt great from the moment I put them on until the moment I retired them. The thing this receiver does well is deliver a clear picture along with some good quality sound when you have things ready to go. The aluminum is sturdy and doesn?t seem like it would fold/bend without a deliberate attempt.
