  j6 o2 H! X/ O% h6 UDue 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.

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.
The huge difference of THD may derive from driver type. ER6i applies balanced armature while the other dynamic.
