Earbuds

What reviewers say

Reviewers agree the earphones are small, comfortable and well built, with an engaging sound and a well-judged midrange; Headfonia placed the tuning between the IE 900's reference sound and the livelier IE 300. SoundGuys found the price high, SoundGuys and Headfonia thought the textured finish may not appeal, and Headfonics found the silicone tips could bring out sibilance.
