I tried to find a place where I could try the SR80e, but unsuccessfully. The stores that are selling them around here are online only.
I found a place where I can try the Beyerdynamics, the SoundMAGIC HP150 and the Ultrasone Performance 820. So I think I will just go there to try them first, before deciding anything.
I dunno where you live but in many countries Alessandros are offered as opposed to Grados....both are made by Grado,and offer very similar sound.
For your price I suggest looking for a Alessandro Ms1
