Etymotic Isolator Earphones ER-6 - headphones

The ER-6 Isolator earphones provide outstanding sound quality and isolation in a lightweight, compact package. And at less than half the price of ER-4 earphones, they're an incredible value. Because these earphones were designed to match the acoustic response of the open ear, their response accuracy surpasses that of all other earphones and earbuds in their class. With their 15-20 dB of isolation, the ER-6's offer more external noise reduction than any other noise-reduction earphone. Why is isolation important? By blocking out ambient sounds, you can hear the full range of today's digital recordings without having to play them at unnaturally high and potentially unsafe levels. Since you don't have to boost the volume to overcome external noise, ear-overload distortion is minimized. The ER-6 Isolator earphone system includes: 5' cord with 3.5 mm stereo phone plug; 2 double-flanged silicone eartips; 2 foam eartips; 2 replacement filters; Filter-changing tool; Shirt clip; Pouch.
