Ultimate Ears has introduced its new UE-4 Pro Custom earphones, which are handcrafted for a custom in-ear fit, and feature a proprietary dual-armature, dual-bore design, a passive crossover, the ability to reduce ambient noise 26 to 28 decibels, and an included personalized protective carrying case. What makes the UE-4 Pro more special is that it can be outfitted with an optional ambient feature designed for musicians who need to hear both the monitor and the noise of the crowd. You can prchase the Ultimate Ears UE-4 Pro Custom earphones for $400, or $450 with the optional ambient feature. [iLounge]

Ultimate Ears has recently introduced two new MetroFi earbuds at CES 2009 in Las Vegas. Both headphones offer 16 decibels of noise isolation and provide the single-driver, in-ear design. The Ultimate Ears 170 and 220 will be available in vi models featuring an integrated microphone for calls and remote button for call management and basic playback control. You can purchase them in February for $50 and $80, respectively. Meanwhile, the vi models will sell for $10 more. [iLounge]

The super.fi 5 — not to be confused with the super.fi 5 Pro or EB models — fills a gap in UE’s lineup between the super.fi 4 and the 5 Pro, hitting the $170 price point. The super.fi 5 has only a single driver per earpiece; it manages to produces good sound, but not at the level of the dual-driver super.fi 5 Pro. UE’s cables feel sturdy, and their rigidity and cable slider keep them from tangling too easily. For an extra $20, you can get the super.fi 5vi, which has an inline module that sends/ends calls and controls music and video on some cell phones, including the iPhone. [DigitalTrends]
