Ultimate Ears announced Tuesday a new noise-isolating earphone called Ultimate Ears 700. The earphones feature a, "custom-tuned dual-armature layout that separates the broad frequency response - 10 Hz to 16.5 kHz - into two high-fidelity channels per ear."

To translate that: The earphones have two hi-fidelity speakers in each ear piece, but the company has worked to keep them quite small (each piece is smaller than a U.S. dime)

The earphones come with an assortment of earpieces to accommodate different ears (small, medium, and large), as well as the option of a Comply foam cushion. Ultimate Ears said that the design of these ear pieces provides for a better fit, and a better seal.

The company said this better fit and seal provides passive noise-isolation of up to 26 dB. A hard case to carry your earphones is also included.

Noise-isolation is different from noise-cancellation. With isolation, the earphone is intended to simply keep out external noise through the fit and seal of the device, while noise-cancellation uses soundwaves to literally cancel out noise. Each approach has its own merits, uses, applications, and fans.

The Ultimate Ears 700 noise-isolating earphones are expected to be available in the U.S. and Europe beginning in April for a suggested retail price of $229.99 (U.S.).
