I've gone through a number of in-ears and cans in my life and these have got to be the best value of any of them. I used to use Shure E4cs, which were great but very "honest" and flat. These are much more listenable phones with fantastic separation. The low end is convincing in a way which I've not experienced before with in-ears. It used to be that if I was going somewhere and wanted good sound quality, I'd take my Sennheiser HD25 cans with me, and if I wanted portability I'd go with the Shures, accepting that I would not get anywhere near the same bass response. These 'phones have changed that - I only want to take these out and about with me. They're comfortable, they sound amazing, and they're cheap as chips. It's a no brainer really.
