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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lives up to the hype. *by on Reviewed in India 16 August 2026* They sound great, lives up to the hype. At least for me. Comfortable on the ears, fits well. But not sure about the durability part. It could be an issue. Will have to wait and see. ### ⭐⭐⭐ Descent product without mic *by on Reviewed in India 10 February 2026* It has a decent sound quality..since I have used ksc35 which has better warm sound signature compared to Kph40..try buying it in headphone zone instead for 2000 Rs less price. It's costly here on Amazon ### ⭐⭐⭐⭐⭐ Beyond value for money - It’s a steal! *by on Reviewed in the United Kingdom 19 July 2026* I feel like I cheated Koss - genuinely. Price to performance comparison just doesn’t tally.Backstory to my purchase decision: My last DAP was well over two decades ago, I’ve been streaming music since then and cycled through most of the music streaming platforms pairing with popular comfort bluetooth headphones and earbuds. It was recently I thought I’d break the cycle of music subscription and actually own my music once again (and forever) and I invested in a DAP for that purpose.Since audiophile headphones brings out the best in Hi-Res DAPs, I wanted to ease myself in and use a reference headphone first instead of outrightly purchasing a headphone like the Sennheiser HD 490 Pro. I read reviews about this particular headphone and thought I’d give it a go. I’m no audiophile with technical sonic knowledge but like a lot of people, I enjoy decent music and strive to hear every single detail as they were recorded in the studio and intended to be heard. Wow! This small, unassuming weightless thing weighs a lot in raw output. it’s not perfect, neither is it in the same rank as a higher end audiophile headphones but at £41.99 price point? If the exact drivers in this headphones were to be in a premium housing and there’s a £150 - 200 price tag on it, I’d still think it’s a decent buy.Vocals are clear and crisp, detail retrieval is decent and sound stage is wide. In some live recordings, it actually feels like I’m in the midst of the performance. There’s no way I won’t own more than one of this unit. They’re passive as passive can get - no DAC, amp or DSP and will retain its value for a very long time for this reason. I’d even gift them to friends and family.The only niggle is - cable is short but for me personally? that's negligible and won't receive a star less because of that. You may forget this thing is on your head, it's that light in weight. You can do other activities, work-out etc with this on as it clamps on your head without compromising on comfort. Something to bear in mind is - it's an open-back headphone which means it relies on air for sound to travel freely, that means sounds from your surroundings will bleed into your music and people around you will hear your music, so it's not the type to use on public transport, on a plane or on a busy street.Finally, if you’re on the fence, just pick one up! Your ears will be happy and your wallet will approve. ## Frequently Bought Together - Koss KPH40 Utility On-Ear Headphones, Detachable Interchangeable Cord System, Retro Style, Ultra Lightweight Design (Stealth Black) - YAXI EARPADS for Koss PORTAPRO (Black) - Koss KSC75 Portable On-Ear Clip Headphones, Retro Style, Ultra Lightweight, Silver and Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/419343905-kph40-utility-on-ear-headphones-detachable-interchangeable-cord-system-ultra](https://www.desertcart.com.ar/products/419343905-kph40-utility-on-ear-headphones-detachable-interchangeable-cord-system-ultra) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-09*
