Pros: natural, spacious sound, detail, comfort
Cons: takes a while to burn in..But worth it!
I find these wonderful little Sennheisers to be a very natural sounding headphone. They take a while to burn in but once that is done they are the sort of headphones that one puts on and forgets the equipment and just enjoys the music. Very similar to my Stax headphones in sound I feel.
Well worth it I think and though as per normal with forums, once a year old it is almost forgotten it is still worthy of comparison to the best out there! These are my go to phones now!
