Best I ever had
Pros: Superb sound, very detailed, strong bass, an awesome soundstage, no microphonic, good built quality
Cons: the sound tuning is useless, earhook, cable
I've been using Sennheiser IE8 for 2 years and its still awesome. sadly I lost it about 2 months ago.
The first time I use it, it sounded ordinary but after several days of burning in I finally found the true sound that is so amazing.
The sound is detailed, clean instrument separation, strong bass, and an awesome soundstage, and no microphonic...
but after using it for a year I have to buy a new cable because the cable broke up, and also I found the earhook is not practical to use. I got my perfect seal from the medium sized double flange tips after experimenting with all the ten tips provided. and It's so comfortable also. The carrying case is neat because it carries two reserve tips, cleaning tools, a microfiber cloth, and your IE8, but the design is complicated.
well its quite pricey and because this is an IEM people didn't see that this thing is expensive. And you know, it just so sad.

























overall I have not so much time to try it out...so...those are current feelings for the ie8
