Logitech UE 900 In-Ear Monitors Page 2
What set UE's previous flagship apart from other multi-armature monsters of the era was its commitment to the fun factor and delivering sound the general consumer could easily enjoy. In the world of accuracy-focused BA monitors, the Triple.Fi 10 catered to fans of punch and power. The new UE 900 even more so attempts to please both audiophiles and casual listeners, with a better-balanced sound that still doesn't skimp on bass. With its dual bass drivers, the UE 900 provides bass that is deep, punchy, and articulate. The response is flatter compared to the TF10, with more linear sub-bass extension and less mid-bass boost for a tighter, more natural-sounding low end. The resulting tone is less warm compared to the TF10, though still warmer than sets such as the HiFiMan RE272.
The lower midrange of the UE 900 is more prominent compared to the infamously mid-recessed TF10, producing a sound signature with a much less obvious v-shape. Vocals are less distant and the midrange sounds fuller and richer. Upper mids are de-emphasized, however, resulting in slight veiling. Female vocals especially seem less intelligible compared to sets such as the HiFiMan RE272 and Shure SE530.
Treble response is quite inoffensive. The UE900 doesn't lack treble emphasis on the grand scale, providing a brighter sound with more treble presence than some popular triple-driver sets, such as the Shure SE530. Still, its treble is smoother compared to the TF10 and often does a better job of avoiding harshness and sibilance,
The presentation of the UE 900 remains wide but also manages impressive depth on-par with the pricier Phonak PFE232. Instrument separation and imaging are good for an in-ear, providing an immersive listening experience.
The Ultimate Ears UE 900 is a high-end earphone for the masses, presenting itself as a well thought-out replacement for the iconic TF10, both sonically and as an overall package. The improved ergonomics and functionality supplement the punchy sound that is forgiving of lower-bitrate tracks.
One thing the UE 900 is not is an ultra-revealing, flat-response monitor some audiophiles crave. The upper midrange, for one, can appear a bit veiled and the tone has a warm overall tilt despite the prominent treble. Still, the new UE flagship gets more right than it does wrong, and with the UE 900 as its replacement, the outgoing TF10 won't be missed by many.
