Closed cans that sound good ?
From what I have auditioned so far, only closed can that I find I liked were the Focal Stellia. Quite simply because they were the least "closed back sounding" headphones I have every tried.
If you have a chance, would suggest giving it a listen at your local friendly headphone shop before committing. Different people's ears hear things differently, so what may be nice to me may not apply to you.
