“I wonder why UERM is often disregarded when picking from $1000 range. I'm guessing that it's due to "only" having 3 drivers, versus having 8 drivers per side. I can say with confidence that driver number does not equal sound quality(for the most part). Another reason I see why UERM might not be picked is its sound sig. It's perfectly flat. Personally, I love this. Reference sound with...” --kimvictor
“ This is my very first pair of custom IEMs after trying almost all of the high end universal IEMs -- SE530, UE Super Fi 10, Etymotics etc. The sound of these UE11 Pros is superior in every way to all of the universal ones I had, but even more important they stay in my ear and provide a proper seal. Since my ear canals get very narrow, I found it very difficult to get any of my universals to...” --alyanm
“ I had owned the UE-10's before this for about 3 years. So upgrading to these was a huge improvement in my opinion. Very nice full sound, with improved frequency response from 20 Hz to 18,000 Hz. Bass is much more present on these but not too overly stated. Gorgeous build quality. Very happy with these In ear monitors, I also own the JH-16's and still love listening to these all the time on...” --Richard Devine
“ To start, I purchased these for two reasons. I am a live audio engineer, so I use these for mixing monitors and as my personal monitors when I sing Tenor as part of my group. These have two speakers per ear. Low/Mid and High. 119db @1mw with an impendance of 21 ohms which means your iphone can drive these quite poorly. My initial View: I have been...” --hagosrush
“ 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
“ 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
“ i was excited over my first custom IEM's ever, I was also excited because i've been a sucker for the Ultimate Ears sound for a long time. Now I know that Logitech is now in charge of UE, but I still felt like these would be very musical CIEM's, as the Ultimate Ears commercial line is so well known for their musicality factor. After a month of waiting due to having to get impressions, and then...” --IEMagnet01
