Pros: seal, cables
I like these more than my Monster Turbines. Less good than the Shure e4c, different price point I know. They're more difficult to insert than the average IEM. Other users seem to find them comfortable enough but not me, not at all. Extended listening gives me a bit of pain. The ear tips are fantastic, it's the phones themselves & how they angle into my ear plus the cable. Initially I wanted to replace my broke e4cs with a current $300ish Shure IEM, I'm glad I picked these up so I know not to go with the current Shure designs on the pricier models. The sound is good but I've never "loved" these headphones like I have others in the past.
Being disappointed with three well reviewed $100ish IEMs (Turbines, SE215 & Bose IE2), I might save for pricier IEMs and stick with "out-ear" when there's only $100 in my pocket.
