6 f1 q4 V! W2 tEtymotic ER6i is a in-the-ear type stereo headset. It provides a isolation of over 25dB against the noise outside. Below is the measurement done this morning in AE lab, CDC.

The frequency response of ER6i conforms to the Type4.3 ear simulator well, which is shown as below.

Response of Bass-Rich ear bud (Brand Senmai)
Compared with the response given above, the ER6i’s response below 1 KHz is quite flat, within ±2dB. Instead, the Bass-Rich ear bud has a peak around 500Hz, which will result in plenty of bass elements while listening music. And that’s why ER6i is designed to classic music without too much bass.
