I was going to update my first post but thought it would be better to start new with a more refined request.
I have been doing some research but I'm away from home and have limited bandwidth.
I'm looking for a headphone which has a large sound stage, clear with accurate bass but not base heavy.
They cannot be more than 250ohms since I will use them with gs4. They need to be closed/semi closed or sound isolating since I need to drown out London noise.
My budget is upto £300
