These instantly became my favorite headphones. They sound AMAZINGLY good! The bass is very deep yet not boomy, precise and tight. Highs are very smooth and everything is very well balanced. They are also super comfortable - I often forget I have them on. I don't think I'll ever buy closed back headphones for music listening - these are open back and sound "open and wide". Love these!

It's so stupid and crazy that this is probably one of the best quality-to-value headphones I've ever purchased. I have had dozens of headphones, my current round is a Shure 840A, Hifiman he400se, and the DT 990 pro (mostly for recording), and I've been stunned by how ridiculous good these KOSS headphones are compared to these 100 to 200 USD headphones. It's that ridiculous. I typically use a autoeq on my android phone or EQ on my desktop, but I still cannot say enough good things about this headphone. They're extremely comfortable, I've worn them for hours at a time. I've only adjusted the band ONE time, it fits perfectly and they do not fall of my head. I've used them for playing games on Playstation 4 via the controller's headphone plug in, I've cleaned my house with them on, I've plugged them into several USB DAC's without issue. I've never been so impressed by such a cheap pair of headphones. Tonality-wise, they compare with many IEM's, and I would prefer them over IEM's in most cases just because they're so simple to wear or use. IEM's hurt my ears so I'm unlucky in that respect, but these are a perfect alternative to those. If you can pay between 20 or 30 dollars to get a pair of headphones that punches this high? Just do it. They are that good for what you're paying. It must have something do with the design of the driver inside these headphone, because they look like they can't do anything when you first take them out of the package, but I've listened to loads of genres without issue. These sound warm, but it can handle bass on IDM or electronic music, the mid's are good, the treble is good, overall I really enjoy how versatile these are. They sort of remind me of those BLON B.L. 03's that came out in the IEM world years ago. Just a really fun pair of headphones. I bought my dad the KSC75 for father's day, but honestly I want a pair now too!

Excellent sounding headphones. A little mor fragile than I'd like but should hold up well enough if not treated too roughly.

This is the best. I haven’t experienced the headband issue but I will say if you put them on and off by grabbing using two hands and grabbing from the top half of the band or where the two connectors for the band meet you will pretty much prevent them from ever breaking.The cable and mic are great and work with both Android and iPhone.They are so comfortable I’ve fallen asleep with them on without breaking them ymmv.Not the most portable and I wish they came with a zippered hard case.Cord length is bit short for laptop use but just right for phone use.If you want to turn these into Bluetooth cheaply go buy fiio Bluetooth headphone adapter for 20 bucks.I got the blue kph30i for 25 bucks so it was definitely a steal bargain. And the Bluetooth adaptor form fiio made these cheaper then the official koss wireless kph30i. Totalling 45 bucks if you don’t mind the cable down your shirt.

Good sounding pair of headphones, a bit fragile on the plastic side and not as airy as the koss ksc75, but still the fit is good. they are a bit more bassy, but still you get a clear sound. The cable is made out silicon and seems to have a good quality.
