Great detail. very well eq-able. Some people complain about lack of bass, but the bass is well detailed and tight. My LG V50 drives them perfectly. audiophile class iems. Can't believe they can make it and ship it for this money. The highs are clear and crisp. I would describe them as balanced leaning towards a bit trebled Iems. But still people need to understand that these are for critical listening. Having said that, they aren't dpot on, but still, for the money...
Mids are recessed and because they are real trebble spankers people should be careful as they can be quite harmful to ears. But I am rather critical.
Great headphone.
