Ok, so I've had these headphones for about a week and im actually using them while writing this reveiw 😅. I'm going to assume you already know what comes in the box.My first impression was "meh". The sound quality is clear enough but they have a very odd frequency response. Me being a sound geek, thought i could fix this with a little EQing.I went into my phone's sound settings and messed with the equalizer until i was satisfied. Now they sound a lot better, the picture i put with this review is a screenshot of those settings if you want to copy them. Keep in mind i listen to a lot of EDM so i like a flatter, truer, how-the-artist-intended sound. You might want to EQ yours differently based on the genre you listen to most often (more treble for pop music, more bass for rap/hip-hop). You can also do this with computers but you have to download a software for it. I bought these headphones for on-the-go use though, so this is fine for me.One of the reasons i bought these headphones is because i heard how comfortable they were. I was a little sceptical but after i tested them out... DAMN these cans are comfy, a little on the warm side but that's not too big a problem. They're actually so comfortable that i accidentally went to sleep with them on. The earpads are made out a really nice material that isn't sticky like leather. It's kinda like suede.Another reason i bought these is because all the headphones i have already, focus on the sound quality over how they look, if you know what i mean. These are perfect style-wise for me. I love the sleek, black, matte finish with silver and white detailing. One problem i have with the style of most headphones is that the headband fits really snug to the head, making the earcups stick out oddly (the AKG K167 for example). The Sennheisers dont do this. These are the first over-ear headphones that i feel comfortable wearing in public.They're relatively easy to transport, the detachable cable helps but the earcups don't rotate. They fit in my bag just fine though. I've seen in a few reviews that people think the phone cable is too short. Honestly i wouldn't want it any longer, the cable doesn't really need to be any longer than the distance between the headphones and the furthest point i can extend my arm to. Only thing different i would've done is make it a braided cable instead of rubber but that's just me.As far as build quality goes, theyre pretty sturdy and they feel high-end. They're somewhat flexible, enough to where they won't break easily but are still comfortable.Anywho, here's the quick ratings for the people that couldn't care less about my rambling.Sound out of box: 6/10Sound after EQing: 9/10Comfort: 42/10Style (personal preference): 9/10Ease of transportation: 6/10Build quality: 8/10Overall 8/10Overall, these are really nice headphones, but need a little tweaking sound-wise before i would consider them amazing. They are increadibly comfortable however, so that makes them worth it imo. Hope i helped.Kthanksbye.
