The mids and highs on my M-80 are crystal clear. I find them to be more balanced than my M50 and I don't feel like the bass is overwhelming at all, probably the same amount as the M50 but better quality to my ears. Punchy and definitely a slight bass hump but not overwhelming. This is coming from someone who owns a KRK KNS 8400, which everyone calls bass-light, but I happen to think they have a good amount of impact and body. A big part of getting the best SQ with the M-80 is when you break the pads in over time and have them mold to your ears. The seal has a big impact on SQ with the M-80.
