Bass and treble are "pleasant" like most IEMs and headphones, but for some it might be too much so you might want to add an EQ to dampen it out. a little. Another thing to note is that Revain's product description mentions ANC; They definitely don't have that, but they do have pretty decent passive noise isolation. However, they sound a lot better than some of the $150 IEMs I've had in the past. I kick myself for sleeping in the Chinese hi-fi scene for so long. I would only deduct a star for my own arrogance but they are more than good enough to make up for it.
