First of all, I want to mention that I have 6 pairs of Roland RH-200 headphones. Also, keep in mind that one of the most subjective things in audio esotericizm is choosing headphones for mixing / monitoring that'll suit you, i.e. how You want to hear Your favorite music. In my case, it's obvious that I'm a fan of Roland. Likewise, I hate overemphasized low frequencies. The RH-200's are super balanced, smooth and sharp enough at high frequencies, without irritatingly booming bass (there's nothing worse than overemphasized bass). I can listen to my favorite albums, trilogies, watch movies etc. for up to 6 hours, and then continue to mix music without over-frying my ears. I searched and tried (and bought) a lot of other brands and unjustifiably more expensive models (i.e. AKG, Ultrasone), including some of the other Roland models, but none came close to the sound quality of the RH-200. The closest to that sound impression that I managed to find, in my case, is the AudioTechnica ATH-M50x, which, together with RH-200, are probably similar / identical in design to the "cult" model Sony MDR-7506. The ATH-M50x, although slightly better than the RH-200 in terms of build quality, have overemphasized bass, are OK for headbanging, but impossible for mixing, thanks to the low-end mud. A few days ago, I decided to try the Roland RH-A30 myself. Although it is a relatively older model, it is improved in every respect in terms of build quality and tone compared to the RH-200. The open-air design is super comfortable and contributes to a better sound stage and positioning of instruments within the mix. The bass is stronger, but tamed enough (thank God), and the treble is sharper (maybe more fatiguing in the long run), compared to the RH-200. All in all, after half an hour I ordered a second pair of the same headphones, and I will most likely at some point also have 6 pairs. For backup LOL. After all said, it makes no sense to write about the shortcomings (the only thing that could be improved: there is no choice of coiled / uncoiled cable and there is no detachable cable). Sure, there are more expensive headphones out there for so-called ''audiophiles''. Happy hunt and good luck with that. On the other hand, it should be said that Roland RH-A30 is a serious precision tool for producing, mixing, mastering, and more importantly, enjoying the music. I've fallen in love with music again! My #1 headphones right now! Thanks Muziker!
