I can only compare these to the headphones I've spent a significant amount of time with, namely the Audio Technica ATH-M50, Koss Sportapros (still my go-to workout headphones), Koss KSC75, and the RHA-M750i, but my first impression of the 58x is that they're lively, clear, flatter than I'm used to (but not clinically so), and they have a musical richness that brings the source material to life in a way I've never experienced before. While the M50's bring a bit more low end muscle, the 58x has more bass than I was expecting, and these kept up fine for every genre I've tested thus far, including classic rock, post-punk, thrash, death metal, lo-fi black metal, funeral doom, synthpop, rap, prog... everything I could think of to try, basically, and these things performed admirably. I gather these might benefit from a dedicated headphone amp, but I had no trouble driving them from my iPhone X. Depending on the source, I could listen reasonably loud with the volume set anywhere from 6 to 8 or so, and I could always go quite a bit louder than my personal threshold. Fit and finish seems very good overall: nothing astray or askew, design is clean, and the dark grey grill is beautiful in person. I'm not really a fan of the glossy black headband, but I wouldn't say it looks particularly "cheap" as some other commenters have; I'd just prefer a nice matte finish to minimize fingerprints. Comfort is subjective: I think these are quite comfortable overall but agree that the clamping force is fairly high, though it was easy to stretch the band a wee bit and make them fit more comfortably. The velour pads feel like a warm hug, but not unbearably so. I'd say these are wonderful headphones at just about any price... but at $150? These are an absolute steal. If you're considering these, I doubt you'll be disappointed.
