I really like these. I've owned the Sony XM5s and the Bose Q45s, not counting the Skull Crushers, Marshall's, Beats Solos, and Soundcore Q35s, because none of those compare to the first two. I will keep it real here, these are not the 5s or 45s in sound, or design quality, but they shouldn't be. I paid over $300 for those two and paid a 3rd of the price for these. I got these used for like $86.The Sound Quality on these Sonys are very good not great for the music I listen to. I listen to mostly Hip-hop, then r&b, Soul, and Gospel when in the mood. These for sure bump. The bass on these are clean, crisp, and just bang. The bass is actually better than any of the headphones listed above. I consider myself an audiophile, I've always been into music and quality sound. Searching for the best sound I can find. The mids and highs on these don't compare to the 5s or 45s at all but they also aren't bad. For the price, build quality, and battery life, you can't go wrong. If you love strictly vocals these don't super shine in that category. If you love bass and want a nice clean sharp sounding headphones, that should last a while, these are amazing for what I paid for them. If these go up to original price in the mid $200s I would just spend a little more for the 5s because those are the best headphones I've ever heard from the ones I've listened to. For sub $100, for the music I listen to, these can't be beat. My one and only complaint, which has been mentioned in the comments, is they don't get as loud as I'd like, which is sad because they for sure can handle it. At full blast they will give you a great experience and the noise canceling is very good. Again the 5s and 45s are better at noise canceling by a small margin, see a theme here? But on a plane, I zone out, and am in my own world.Bottom line you won't be disappointed unless you want to lose your hearing at a young or old age I guess, and need honestly speaking, too much volume. I wish I had more volume but not by much. These work just fine, and it's probably a good thing they don't get louder because I'd listen to them as loud as they would go, that's just me.
