Etymotic 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.

& k+ J0 m1 ~/ j+ e, x: f, GDue 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.

Frequency Response and THD: Right Channel (ER6i)
The frequency response of ER6i conforms to the Type4.3 ear simulator well, which is shown as below.

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.
