In the end great great shoe again from keen Till then. Pobres en matices si se les comparan, por ejemplo, con los ATH-M50x, pero claro, estos otros ya compiten en otro segmento. The noise cancellation is the best I have heard. I only mention the above, some things I didnt specifically like about the BTR5 (rather than the things I did) to contrast with the Shanling UP4. OMG this is great. I installed the u-brackets from the top and screwed the wing-nuts from the bottom. They also come with a lovely case and fold away pretty small. It was one of the first things that I noticed when I used these for the first time when playing games. I stumbled across these and it was a GREAT purchase.
