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. Review: WHAT IN TARNATION. BUY THESE AND A PAIR OF YAXXI PADS - IMPORTANT DETAIL - the stock earpads are fine, but an instant, OUTRAGEOUSLY GOOD upgrade for them is a pair of yaxxi pads. The ones designed for the Koss Porta Pro's are the ones you want. Get whatever color you want. Orange gives some proper starlord 80's retro cred. *update* I still adore them, but I have found a cheap way to add an in-line mic. Get a replacement cord for something like the bose 700 or QC25, anything with a 2.5 to 3.5mm plug will work. Much, much cheaper than the usb-c or apple cord Koss sells. Side-benefit is it also made the cord a bit longer, which I've found nice. These have no right to sound so legendary. I'm serious. This sound in a $300 pair of headphones would be justifiable. They sound amazing out of everything. Dedicated digital dac? yep. Tube amp? yep. headphone jack on my lame laptop? YEP. They don't have that cramped, squeezy feel of the KPH30's. They sound better than the 30's (which were already amazing) These little guys just disappear on your head. Even if you think you hate headphones that sit on your ears, these (with some yaxxi pads) just might as well not exist on your head. The sound is just fine from the stock earpads, but I bought some yaxxi pads (available here on desertcart) in orange for some more retro look and the comfort went up dramatically. Yaxxi's are like $10 and so luxuriously soft and ethereal. As for tuning, they're supremely chill. The same kind of vibe that my $300 Meze Classic 99's have. They're not the sparkly goddess sound that makes people love or hate Grado, but they're not overbearing anywhere in the sound signature, so mids are nice and rich, with deep, punchy sub-bass that you would NEVER expect (beastie boys intergalactic HITS) The treble is gentle and clean, and they're just supremely laid back, enjoyable things to listen to. I find the only area they don't trade punches with $300 headphones on is imaging. It's not bad by any means, but you don't get that "you can point at exactly where in front of you the sound is" level of detail that some Grado sr60's would give you. But the fact that the only place I can start to find a complaint is imaging, and using a pair of headphones that cost twice the money as an example should start to paint a picture that these are truly special. The party piece in the sound stage to me, is that they are tuned superbly for outdoor use too. No, they aren't going to isolate the world, but they don't get drowned out to nothing on the ferry like my Hifiman Hex4's do. I don't necessarily always need headphones outside that isolate the world, but I do need them to sound good if they don't. The only actual gripe I have is the cord doesn't include the nice little in-line microphone and single button control that the KPH30i's have. Since I do use these outdoors a lot (they're just so light and tiny that they can just be chucked in my bag) I would REALLY have liked to see a microphone. And maybe if there was a way to give the earcups a way to swivel and lay flat, I'd like that, as it'd make them even more pack-able. As it is, these are some truly god-tier beater headphones. But seriously, get some Porta Pro yaxxi pads. There's no work involved to swap them, just peel the old ones off and stretch the new ones on. ## Features - Open-Back, On-Ear Design, Retro Look - Ultra Lightweight, Stainless Steel Chassis - Audiophile Sound Performance - Soft, Foam Ear Cushions - 3.5mm Utility Cord Included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KZC94X1 | | Additional Features | Lightweight | | Age Range Description | Adult | | Antenna Location | Everyday Use, Traveling, Exercising, Recording | | Audio Driver Type | Dynamic Driver | | Best Sellers Rank | #7,353 in Electronics ( See Top 100 in Electronics ) #212 in On-Ear Headphones #573 in Earbud & In-Ear Headphones | | Brand | Koss | | Brand Name | Koss | | Built-In Media | Cable | | Cable Features | Detachable | | Color | Stealth Black | | Compatible Devices | Devices with 3.5mm audio jack, USB-C port, or Lightning port | | Connectivity Technology | Wired | | Control Method | Touch | | Control Type | Media Control | | Controller Type | Wired | | Customer Package Type | FFP | | Customer Reviews | 4.3 out of 5 stars 1,349 Reviews | | Ear Placement | On Ear | | Earpiece Shape | Rounded, flat or slightly curved surface | | Enclosure Material | Stainless Steel | | Form Factor | On Ear | | Frequency Range | 20 Hz - 20,000 Hz | | Frequency Response | 25000 hertz | | Headphone Folding Features | On Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | On Ear | | Impedance | 60 ohm | | Item Weight | 0.11 kg | | Manufacturer | Koss | | Model Name | KPH40 Utility Parent | | Model Number | KPH40 Utility Parent | | Noise Control | None | | Number of Items | 1 | | Sensitivity | 101 db | | Style Name | open-back | | Theme | Retro | | UPC | 021299197455 | | Unit Count | 1 Count | | Warranty Description | Limited Lifetime Warranty | | Water Resistance Level | Not Water Resistant | | Wireless Technology | Bluetooth | ## Product Details - **Brand:** Koss - **Color:** Stealth Black - **Ear Placement:** On Ear - **Form Factor:** On Ear - **Impedance:** 60 ohm ## Images ![Koss KPH40 Utility On-Ear Headphones, Stealth Grey, Interchangeable Cord - Image 1](https://m.media-amazon.com/images/I/51Sm7vzebiL.jpg) ![Koss KPH40 Utility On-Ear Headphones, Stealth Grey, Interchangeable Cord - Image 2](https://m.media-amazon.com/images/I/618uRgf0rVL.jpg) ![Koss KPH40 Utility On-Ear Headphones, Stealth Grey, Interchangeable Cord - Image 3](https://m.media-amazon.com/images/I/71QAmhgvskL.jpg) ![Koss KPH40 Utility On-Ear Headphones, Stealth Grey, Interchangeable Cord - Image 4](https://m.media-amazon.com/images/I/715mYVvf-QL.jpg) ![Koss KPH40 Utility On-Ear Headphones, Stealth Grey, Interchangeable Cord - Image 5](https://m.media-amazon.com/images/I/513KkfERbwL.jpg) ## Available Options This product comes in different **Color** options. ## 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 β€˜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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ More comfortable and a little softer-sounding than the KPH30. *by A***Y on April 5, 2023* I love the sound of the Koss KPH30.

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.
