MODEL- ER-6C               VENDOR- ETYMOTIC RESEARCH
     
FEATURES- ER 6C Isolator Earphones- Black finish
       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.
