“ I personally prefer the sound of the "Westone" series to the "UM" products. I use my IEM's for listening to pre-recorded music. The sound of the UM series is very good, but the WESTONE 4R is the closest I have come to the sound of my FOCAL speakers. While the sound was pleasing when using the COMPLY foam tips, the UM56 custom tips took everything up a level. ...” --psych_major
“ 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
“Switched to these from a TDK BA200 and the difference is phenomenal. I only paid about 80quid more for these than the BA200 with all the discounted sets appearing here and there. The first thing I noticed after getting a good fit was the immense soundstage. They are very detailed and clear in reproducing music, but are rather lenient on most lower quality mp3 recordings. This is a plus for me...” --efgwew
“ 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
“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

“ http://www.head-fi.org/forum/thread/552996/review-westone-ac2-dual-driver-custom-in-ear-monitor See above for my in depth review. In general, the Westone AC2 is a great addition to the somewhat crowded entry level custom IEM market. It has its own flavor that will surely please some people. What would be the point if Westone just released another UE4pro/LiveWires sounding custom,...” --project86
