I already have the PFE012, which I use indoors for critical listening (as well as for movies and games). I was going to get another pair of PFE012 to use outdoors, but I use the Sansa Clip Zip, which doesn't fully exploit its true potential. I looked at various low-cost alternatives with similar sound-signature to the PFE012 and the NE700X seems to be the ideal choice. But in the UK it's priced at £65 (inc Del). So is it worth opting for the NE700X or should I spend £30 extra and get another PFE012 (or something entirely different). PS: I should point out that I walk a lot and spend ~2 hours in the gym (5 times a week). I don't want to ruin my primary phones hence why I need a second pair.
