Summary: This is my first earphone that I spent more than $200, and I am not pleased with this item. Although it feels very comfortable when listening music, my ear and neck starts to feel hurting after using more than an hour. I am think of exchanging this item to either pfe112 or er4 or shure535.
Pros: comfortable, awesome base, ok mid (little more vocal would be nice)
Cons: low high unless EQ, bad ear guide (too hard), ear and neck hurts after using more than an hour
Summary: My score seems negative but do not be put off. I have already sold my pair of westone 4s as I personally do not find them to be particularly enjoyable. However, up till now, they are still the best pair of universal iems I have used. The sound is pretty balanced, though not dead accurate. The mids are slighlty forward and warm, being very enjoyable. The treble is clear and extended yet smooth and the bass is well extended though not the most impactful.
Pros: "Sweet" sound with no seriously over empahsized frequencies
Cons: Overpriced, Poor Warranty, Sound could be better
