Review: 6 Month Review - I absolutely love these headphones. I picked up the Koss KPH40 Utility On-Ear Headphones and they’ve completely won me over. I did upgrade them with the official Koss oversized replacement cushion ear pads, and that made a huge difference in comfort—highly recommend doing that. I mainly use them with Apple Music on my Mac Mini, while at my desk, and the sound quality is just fantastic for the price. They’re clear, detailed, and have a really enjoyable, natural tuning that makes everything from vocals to instruments shine. They don’t try too hard—they just sound right. They’re also incredibly lightweight, which makes them perfect for long listening sessions. With the upgraded pads, I can wear them for hours without any discomfort. What really surprised me is how much I keep reaching for these over more expensive headphones. There’s just something about the sound and simplicity that makes them so enjoyable. Koss really nailed it with these. Amazing value, great sound, and super comfortable (especially with the upgraded pads). Highly recommend!
Review: More comfortable and a little softer-sounding than the KPH30. - 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.

### ⭐⭐⭐⭐ Crazy Soundstage
*by N***E on October 6, 2023*

When I first got these I got them out of the box and started listening to music, and music for these is pretty good for the price range. Not much sub-bass to speak of, but it's a small driver open back unit. The bass that is there is pretty strong. There's a little bit of bloat in the upper bass range that can be distracting for me right at first, but I find that as I listen longer my ears/brain adjust and it's not too much of a problem. Kick drums and floor toms have a lot of impact, but I don't hear much resonance in them like you might through better headphones. Mids and highs are smooth enough that I don't notice any distracting peaks in tone. Resolution gets better than what these offer, but again, they are 40 dollars. All in all, not a bad sounding unit at all and they are definitely good enough to just relax on the couch, drink a drink, turn your brain off and enjoy music. They are also great if you need to wear something while you are working, doing chores, running errands, or whatever because they aren't so detailed you start to get overly analytical with the music and get distracted. They are also crazy open in terms of sound isolation, so you won't miss out on anything happening in the real world. Sound leak is real though, so I would avoid wearing them anywhere where you might be bothering someone else if they could hear them (libraries, planes, etc.). The soundstage on these, though? *chef's kiss* I was listening to a song where the volume starts low and slowly increases over the first part of the track and I took them off for a second because I thought I had forgotten to switch my source from my living-room speakers to the headphones. It didn't sound like the music was being pumped straight into my ears, it sounded like the music was in the room with me. At full volume, this effect is less noticeable, but the soundstage and imaging are pretty great for headphones at this price range. I'm always hearing sounds that have me looking around the room. You really feel surrounded by what you are listening to. I don't know how many people are going to use these for watching movies, but they are crazy good. I like to use headphones to watch movies at night so I can turn them up loud without disturbing my duplex neighbor. I just watched Resident Evil: Welcome to Raccoon City with these (first movie I've used them with), while running the headphones off of a Fiio BTR5 (bluetooth adapter) connected to my media computer. I took the headphones off probably 4 or 5 times during the movie thinking that I heard something in the room with me, or something happening outside my house. Little faint noises don't just sound quiet, they sound like they are actually around you spatially. The effect is honestly pretty striking. I have other gear that technically sounds better if I really want to get analytical with my listening session, but these really do deliver at this price point. If you're an audiophile you probably have gear better than this, but I would still recommend them just for the reminder that you don't have to spend a fortune to enjoy what you are listening to. For anyone else, or anyone new to the hobby, this is an awesome place to start. For 40 bucks, how can you lose?
