Logitech Ultimate Ears 700
Logitech's high-end earphone label Ultimate Ears this morning launched a higher-end set of personal in-canal models. The Ultimate Ears 700s have dual drivers like more complex earbuds, separating higher and lower frequencies, but are most notable for their frequency range. Sounds range from a low 10Hz up through to 16.5kHz.
As with other earphones of their kind, the 700s provide passive noise cancellation up to 26dB and have multiple ear tips to suit different ear sizes. Logitech plans to have the 700s in stores later this month for $230.
