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.

## Questions & Answers

**Q: Do these use same speakers as Porta Pros?**
A: Officially, I have never seen Koss admit that Kph40 and Porta Pros have the same driver.  But having both, I tested them on a Steely Dan song "Lunch with Gina" and I can't tell any difference in the sound.  So I think it comes to which head band you prefer, the folding Porta Pros or the single band 40.

**Q: Where can you buy a balanced cable for the KPH40 utility headphones?**
A: Just got mine KPH40 and checked the cable. It seems that 2.5mm TRRS socket is indeed balanced, but configured in 3.5mm standard (T: R+, R: L+, R: L-, S: R-). So it's NOT compatible with 2.5mm balanced output (like FIIO BTR5) using "straight" cable. You would have to use crossed cable for this setup (haven't found one yet), or use device with 3.5mm balanced standard.

**Q: Does anyone know when these will be back in stock? I would love to get a pair! :-)**
A: I Believe these are Quite available now (compared when 1st introduced !) either through Amazon- or Koss Factory Direct.

**Q: Koss should make a bluetooth ‘pendant’ for the utility series. that would be the icing. does any know of a bluetooth receiver with 2.5 mm termination?**
A: There are none. The problem here is you need to convert the 2.5mm trrs configuration with a wire. You can get any wire which fits hd598 either balanced or unbalanced. Then only connect to a Bluetooth pendant.

### ⭐⭐⭐⭐ The Only Thing Hurting Them is the Hype
*by J***S on December 4, 2025*

The Koss KPH40 headphones are really good for what they are — a lightweight, budget headphone. If you ended up here after watching a glowing review by a tech influencer stating that these compete with $200 cans, you will probably be disappointed. They just don't, especially if you appreciate strong bass. Detail in the mids and highs are outstanding; no notes. Crisp, sparkly, but not fatiguing. The low end lacks any 'oomph.' I suppose that is mostly to do with how open they are. There is none of the sound pressure you feel from over-the-ear sets. If you try to force them with EQ, you get a ton of distortion. Their comfort is amazing. That is what you get in the trade for the bass, and I think the compromise is a fair one in the right usage case. I forget that I'm wearing these. They're a dream. Getting them adjusted properly is a bit fidgety, but it can be done. They're so light, the clamp force is just right, and the ear pads are soft & breathable. No noise cancellation to speak of; you will be very aware of your surroundings. Whether that is a positive or negative is up to you. Avoid using at high volumes in quiet public places, sound bleeding is significant; don't be *that* person. These are great for casual listening. Teleconferencing. I think they would be amazing for gaming. I have headphones that sound better for not a lot more money, but they're big, hot, and uncomfortable. I reach for the Koss KPH40 far more often. They are not "the best headphones under $200!!!!," but they may be the best for you during most points of the day.
