can i go with a model like the beyerdynamic dt100 or are there better
ones around?

Something like http://remoteaudio.com/hn7506.htm will probably provide the best isolation but there is somewhat of a weight, heat, and cost penalty. Oh, and you have to like the Sony 7506 sound.


what about sennheiser models?

HD 280 Pro is what I use and I think for $80 or so it's a pretty amazing set of phones.



as i will be using it on
different installations, which impedance should i look for?

The HD280s are 64 Ohms and work well on everything I've connected them to. The 300 Ohm version is nonstandard and would give you trouble with most portable audio devices.
