Summary: Thought it would be like a portable Sennheiser HD600, reading all these positive reviews here. Unfortunately it wasn't. * I am not a BASS freak. I think Sennheisers have enough lows for any type of music, though a lot of people don't think so. So I safely ignored the comments on lack of lows on ER4P's. Well, I was wrong. I coudn't really hear anything I'd say below 100Hz. That is bad!
