The Ultimate Ears 700 earphones are said to feature a custom-tuned dual-armature micro design that delivers
highly accurate sound reproduction in a compact design. Each earphone is reportedly smaller than a dime.
The dual-armature layout is engineered to separates the broad frequency response — 10 Hz to 16.5 kHz — into two high-fidelity channels per ear. An assortment of ear cushions is included, along with Comply foam cushions, providing passive noise isolation of up to 26dB, said the company. A hard carrying case is also included for a $229 suggested retail. They are scheduled to be available this month.
