Etymotic Research 3C Insert Earphones (10 Ohm)

Product Code: ER3C-10

  • 10 ohm 
  • Incorporates “touch-proof” electrical connection for safety
  • Duplicates ER•3A smooth frequency response
  • Provides 30+ dB external noise exclusion - equivalent to a single-wall booth when used with deeply-sealed foam eartips
  • Provides 70+ dB isolation (interaural attenuation) between ears; reduces the need for masking
  • Reduces test/retest variability compared to supra-aural earphones
  • Eliminates test errors due to collapsed ear canals
  • Simplifies RECD (Real-Ear-to-Coupler-Difference) measurements
  • May be calibrated in a 2-cc coupler, occluded ear simulator, or 0.4-cc coupler
  • Uses E-A-RLink insert eartips
  • Also available in 50 ohm
  •  See alternative Insert Earphone option, item #OT-02-100
