The ER-6 Isolator Earphones reduce environmental sound levels
15~20 dB, allowing you to hear the full range of todays digital
recordings without having to play them at unnaturally high and
unsafe levels. Since you do not have to boost the volume to
overcome external noise, ear overload distortion is minimized.
True high fidelity sound reproduction requires the reproduced sound
to be as close as possible to the sound of a live performance. ER-6
Isolator Earphones are designed to match the acoustic response of
the open ear.
Includes ER-6C Isolator earphones, 5 ft. cord with 3.5 mm stereo plug,
1 pair 2-flange eartips, 1 pair foam eartips, 2 replacement filters,
Filter changing tool, Shirt clip and Pouch.
* ER-6 Isolator Earphones are small and easily portable. No external
amplifier required. No battery needed.
* ER-6 Isolator Earphones slide into your ears like earplugs, isolating you
from all surrounding noise.
* Noise isolation (34-36 dB) far surpasses that of active noise-canceling
earphones.
* For Travel and Personal Listening
- Airline travel -- plugs directly into most airline audio systems.
- Use with CD, DVD, MP3, MiniDisc players, and Laptop computers.
- In-ear monitoring and mixing
- Can be used with custom Musicians Earplugs.
