Koss KPH40 Utility On-Ear Headphones, Detachable Interchangeable Cord System, Retro Style, Ultra Lightweight Design (Stealth Black)

Honestly I'm shocked. These headphones sound amazing. Incredible resolution, instrument separation, and clarity. It's been a while since music has been this fun. I ordered some Yaxi pads to go with mine and slapped on an EQ from the AutoEQ project on Github. These are probably my favorite headphones I've ever owned. Incredibly light and comfortable while sounding phenomenal.

I couldn't believe the quality of sound I was getting out of these old-fashioned headphones.

nothing to write here,no need to think twice,grab em if you love music..

I had a pair my late grandad and Mum got me Koss headphones similar to these when I was very little for my portable cassette player. But over the years they went missing. But buying this has been the best decision I've made, they sound fantastic and even better than I remember, the bass is punchy and mids and highs are clear but not overpowering, simply better than any other headphones I've used in a long time. Comparing to my very expensive Sony's I very much improve the sound quality on these. You won't regret your purchase and if you want them wireless, get something similar to the FIIP BTR5's.

I had insanely high expectations for these and they surpassed them 10 fold. At such a low cost you literally have nothing to lose

These are a quality headphone that punches above there deceptive looks and price,recommended.

I love the sound of the Koss KPH30. An unexpected treat given their low price, they're airy and have great treble balance and clarity. They're not very comfortable for my big head for more than an hour or so, though, due to pressure on my ears. I figured these would have a similar sound but be more comfortable. For the most part, I was right. They are more comfortable in that they rest lighter on my ears (you can almost forget that you're wearing them). I also like that they barely use any plastic.. I could see the '30s plastic getting brittle and cracking over the years (time will tell, though). These look more elegant, and weigh almost nothing. Not using as much plastic also heightens the impression of quality/luxury (not that these are going to be mistaken for $400 Mezes..). The interchangeable cable is appreciated, as my new phone unfortunately doesn't have a 3.5mm. I haven't purchased the C-cord yet, but it's a nice option to have. Sound-wise, the treble is slightly softer and more rolled-off than the '30s. Still plenty of detail, and they're less fatiguing (not that I'd call the '30s fatiguing.. just that these are even less so). Perhaps a smidge less bassy/punchy, but still good for the class. I'd say these are even more spacious-sounding, though. These are the kind of headphones that you close your eyes and throw your head back to be enveloped in sound. That's a marvel at this price point, and something that Koss probably does the best, which is why despite having significantly more expensive headphones from multiple boutique brands in my collection, I still consider Koss one of my favorite brands and keep coming back to them. You get so much quality sound for the money, they embarrass most brands costing 2-4x as much; and when you do find headphones that are truly better, you look at how the Koss are a mere fraction of the price, and you kind of laugh to yourself about the law of diminishing returns.. So ultimately, while I do miss the extra bite of the treble of the Koss KPH30s, the added comfort and even more spacious sound mean these are still the ones I use most. Even for those of you that have much more expensive sets, I still recommend buying these, even if just to use when you travel. I originally bought these/the KPH30s as a cheap travel set, but I like them so much they're pretty much all I use anymore. It's kinda funny--15+ years ago it was the Koss PortaPro that first captivated me and made me obsessed with sound. I wouldn't have guessed that I'd be back to midrange Koss sets all these years later, but here I am. These feel and sound like a contemporary analog to the PortaPros. In a way, it feels like home to me.

So good are these, and for travelling they are just perfect
