Hey folks,

I'm new here but I visit the forums from time to time via Google.

I've got a pair of Sennheiser HD555's and I've just bought a cmoy amp based on a recommendation however at the same time I'm considering some new headphones for Christmas, I only use the headphones inside so portability is not essential. They must not leak much sound.

I've got my mind set on the Momentums, is it a worthwhile upgrade? Also is there any difference between them and the on ear version? I'd prefer on ear as its around £100 cheaper.

Thanks for any input.
