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.  W, N7 Z5 \1 L# k8 J+ L

Due 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.

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.2 f$ N' A. @# p% ~" C

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.
