“ I bought these a few weeks ago, and like the other reviewer mentioned, they don't do anything too special. They are fairly detailed for an IEM at this level, and provide globs of bass. The inline iphone remote is especially nice. There is quite of bit of microphonics. I will be keeping these as IEMs to use at the gym. ” --Bloodstriker
“ After my CX300II's broke it became a frantic search of a replacement that'll provide me the same kind of quality and bass that I loved from my previous pair. I ended up deciding between antoher pair and the Sennheiser IE60. I havent regretted my choice. Setup: I used my COWON J3 with no amp. I use a custom equalizer (found here on head-fi). The music I listen to is pretty...” --Luchico638
“ Sennheiser is the first “legit” headphone company most people hear of and are generally praised unabashedly by people that lack experience. Well at least that’s what I’ve gotten from in my years in the internet. I’d never been the biggest fan of Sennheiser, mostly because I’d never tried anything in their line above the HD25.

“Build, look and comfort: These iems look very nice, has unique design. The earpieces seem built sturdily, the cable seems durable. These are so comfortable that you mayn't feel they're on your ears after wearing them for some times. I would appreciate flat cable like mh1c or xb series from Sony.

“ Like many other people, I got my cx300's as they were widely available on the high street with not much competition at the time. They are mostly known for their bass which is very abundant. The problem with that much emphasis on bass is the rest of the range suffers. Treble, in particular, suffers quite badly and is drowned out. Add to this very little clarity in the bass which doesn't have...” --Marcus_C
“ I first purchased these because I wanted something good to use. Everyday travelling to and from school/work would take me about 3 hours (round trip); so having good quality IEMs that isolated me from the noisy bus and other distractions was something I wanted to have. I saw these in-store and thought I might as well try them. I've heard of Sennheiser before but was the quality as good as its...” --Luchico638
