Review: Beyond value for money - It’s a steal! - 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.
Review: Welcome back to the early 80's - Looks can be deceiving, but your ears will be believing. Great sound quality and arguably out perform many top recommended sets costing much, much more. Questionable build quality only minus

## 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.

### ⭐⭐⭐⭐ Sound Way More Expensive
*by J***N on 16 September 2025*

Superb sounding portable open backs.I have a pair of Sennheiser 599s which are not high end but are very good. The KPH40s are just as pleasurable to listen to.4.5 stars because the cable sucks.
