positives:
- they sound absolutely amazing. flat frequency response, unbelievable amounts of bass for such a small package (bass is lower / better than on my HS80M), amazing mids and very clear trebbles. vocals sound very natural.
- but the real party trick is the sound stage / metering. it builds a stage in front of you that lets you precisely locate each instrument. separation is therefore amazing. the stage is not particularly wide, but it's incredibly "immersive".
two negatives:
- they give off a slight hiss that's not audible during music, but makes me switch them off when not in use. thus, not ideal as casual PC speakers.
- on bass-heavy tracks they can't play very loud before clipping (which is clearly audible as a weird additional noise, e.g. during kick drum kicks)
overall they're... well the sound is most likely the best you can get (a) at this price point and (b) in this size. but they're not perfect in other regards. they still wow me every time after a year of ownership.
