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
