tried commuting with my ex-90 with the electric tape with a hole .. it did perform well.. isolation was better, but still much better than stock.. didnt hear the bass at all..
but in quiet environments.. i really really love it.. it soinds soooo much better.. whats lacking is just a little eq-ing so the drums might sound better.. i ll try the cling wrap next.. maybe its a lot better than electric tapo.. ahihihihi...
