" F( {5 J* o/ p7 H# o! cEtymotic 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.

Right Channel Isolation (ER6i)
* ?9 {. P0 D" G1 b$ X1 vDue to the in-the-ear design, ER6i provides much better noise canceling compared with normal circumaural earphones and normal earbuds. In the frequency below 1 KHz, the isolation is around 18dB and more than 25dB over 1 KHz, as shown in the pictures above.
2.      Frequency Response and THD
Former try listening gives a feeling that the ER6i lacks in bass and it is proved by its response. Pictures below reveal why it’s bass-free.

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.
