I bought these pads to replace the ATH-M50s pads. I was not certain these would hold up to any sort of hiking. El sonido y micrófonos eran buenos, pero fallaban al poco rato de uso. Love this stuff. This increases comfort slightly, but does make my foot slide around a little when walking downhill in socks. They?re so soft and easy slip on and off. The headsett was like I expected it to be. Im not paying $90 for spanx when there are $20 everywhere, but I may have to :( . Installation also wasn?t as easy as expected due to positioning of the screws. I bought a UE Megaboom 3, but I received a UE Megaboom 1.
