What do you think about the Sennheiser OMX 52? Are they worth a purchase? At home, I'm listening to the PX 100, but for outdoor use I need smaller headphones that I can easily carry in a close Jeans pocket. The included bag looks protective enough. I just wonder if these headphones' sound quality can compete with their outer appearance.

The corresponding Sennheiser website consists of rather useless flash animations, so here's a link to the specifications file:

Or the OMX 70? Probably a similar product. I like the clip-ons for working out.
