Nwz-s760 vs nwz-e053 sound difference
 

Most say a, s, and e lines would sound the same. Just wanted some opinions from people that might had these.

They all sound the same,...they just might differ slightly in features.

I have the sony's ex300 iem's. Any recomendations on a active (sport, running) iem? I'm interested on the shure se215 and maybe the sony's xba2 or 3. The idea is to have a good sounding player but keeping it really compact and to pair it with good sounding iem's for an active life style while trying to maintain the best SQ.
