Can the UE 900’s keep pace with top-shelf custom-fit in-ear monitors? My finding was that the most obvious difference was that the UE 900 could not realistically provide quite the same levels of extreme noise isolation that custom-fit monitors offer. This is one area with custom-fit monitors enjoy—and likely always will enjoy—a clear-cut edge in performance. But, with that said, I would say that the UE 900 comes ever so close to matching the sound quality of the firm’s critically acclaimed In-Ear Reference Monitor (IERM), but at less than half the price. That alone is a remarkable achievement.
How good is the UE 900? My take is that it is one of the finest universal fit earphones on the market today. Relative to top-tier competitors such as the Sennheiser IE80, Shure SE535, or Westone 4, the UE 900’s offers compelling sound quality, a somewhat lower price, and well thought-out ergonomics. Enthusiastically recommended.
