Westone triple balanced armature driver 3-way passive crossover custom. 1 High, 1 Mid, and 1 Low drivers.
“ FitEar has gained a great amount of respect these days, thanks to the venerable FitEar To Go! 334 UIEM. After having owned a TG! 334 I decided to take the plunge into my first custom, the FitEar MH335DW. The first thing I have to mention is the whole process in obtaining these customs. FitEar is a very exclusive company, and apparently there are only two places where you can have...” --VisceriousZERO
“Check out my video review as well: http://www.youtube.com/watch?v=fiFd4lLINAk&feature=youtu.be The f111 is a beautiful IEM. Even with it's "typical" fit, the kind of fit you would normally use with this type of earphone, they sound great. They are warmer and less crisp than the etymotic er4s that is its cousin (they use the same driver). However, with a very...” --luisdent

“ Disclaimer I bought these about 3 years ago, used them a lot and got to "know" them well. The (sort of a) good thing is: They still perform as good as they did when I first tried them on. But that was not too good. Back then I felt disenchanted: they somehow sounded unimpressive, which left me confused. I mean, I based my decision to buy the most expensive earphones I had ever owned solely...” --Checkbox G
“ This a relatively solid case, well cushioned, good sized and very functional. Given that - I am at a complete loss as to why the closure is so poorly made. I bought 2 of these and within 60 days BOTH case latches developed a lateral crack running along the clasp left to right - in one instance it broke off completely. I had bought them from Sweetwater and they replaced both of them...” --Lifter59
“DISCLAIMER This review is based on the demo set at Jaben Singapore, which I have demoed extensively no less than 3 times. Though fit is pretty good, but as perfect fit is not achieved, I shall not be commenting much on the bass of C435. FitEar is a household name in Japan, though they fast gaining popularity in Singapore. TG334 has been a rather big revelation here...” --Joe-Siow
“ **Fitear To Go 334** It's very expensive, it doesn't fit the best due to its huge shell, yet I love it all the same. The sound is sublime. Normally I prefer dynamic IEMs for their weighty low end and texture that most BA earphones can't touch, but the tonal quality, transparency, and high level of detail retrieval bring the Fitear to the top of my list. The openness and...” --cn11

“I bought these as an upgrade from the W3, which while extremely fun, I soon became disappointed in, due to mid bass bleed into the midrange. This caused vocals to become too chesty and distortion rock guitar notes too rounded instead of hard edged. Enter the W4. Fit and Isolation: Westone 4 is extremely comfortable. I love their size and weight. They only...” --shotgunshane
