Ultimate Ears has unveiled its triple.fi 10 Pro in-canal earbuds for portable music audiophiles. The earphones are based on the company's custom-fit UE 10 design used for concert and studio reference listening, and share the same triple-driver output that separates high and low frequencies from each other. Two of these drivers are dedicated to bass reproduction -- important for the low amplification inherent to iPods and other portable players -- while treble is handled by the remaining driver and merged into the final output by a passive crossover, according to Electronista. The triple.fi is expected to ship in late October for $399, and the first 1,000 units will come with two special metallic travel cases; models sold afterward will include only a single hard cover case.
