Sennheiser PMX-100

I travel a lot on trains and now am using an iphone and I also have an ipod.

I use a pair of Sennheiser PMX-100 for portable use. Light-weight supra-aural headphones

with a impedance of 32 ohms these cans can easily be driven by the apple devices.

These are open-back headphones, so everyone around you can hear pretty much everything coming out of them.

The PMX-100 headphones provide very impressive sound quality, the bass is well defined and everything else is decent enough. I have no problems with these headphones. Have been using them for a couple of years and apart from replacing the foam pads they have survived and still going strong.
