From an audio pioneer that’s been in the business since 1958, these earphones look like nothing else on the market, featuring a retrofuturistic metal design that’s entirely adjustable and entirely cool Read More

Weird, Wonderful but need work
These are probably the wackiest earphones I own, when you get these sitting right, it does image similar to having speakers close by and is an interesting sensation that i enjoy, the sound is simply nicely balanced and clean. But the biggest flaw with these is the driver piece that sits just inside your ear, I have average ears, and they are too large for me, after a while the edged start to cause pain from rubbing, so in my opinion these might need an adjustment in size or silicone sleeves maybe ? Don't get me wrong, I love Koss and own 4 pairs of headphones, but these do need work in the comfort department. If it weren't for the discomfort, this would probably be a 5 star, but I feel a large portion of the population would have similar issue to myself when listening to these earphones.

Not for everyone...Excellent for some
As many other reviewers have noted, these are WEIRD Earphones (Koss Fanboys like myself: "STEREOPHONES!"). I've been so curious about these that I've introduced these to my family members and dozens of friends. The verdict: they will NOT fit everyone properly...despite that you can clearly see Koss put a lot of R&D into designing multiple clip bars, adjustable screw-in depth, and adjustable clip-ear angles in their attempt to achieve a "one size fits most" product. Comfort: After about a week of wearing these (my work days: 2 hour commute on phone, 10 hours on PC/DAC, 2 more hours on Phone) and wondering if these would work for me, I decided to screw in the adjustable bars to their deepest position, and only then did I come to the realization that these earphones are designed to *suspend* from the top of your ear and swing into your ear canal, as opposed to using the bar clip to stabilize/support otherwise self-supporting IEMs. From that point on, I've found these relatively comfortable and great-sounding earphones. Note that just because these work on my head/ears does NOT mean they will work on yours; their fit is unique and nothing uncomfortable is worth owning and listening to, even if it sounds great (which thankfully, these do). Build: The housings are a combination of aluminum and good plastics, and the clip bars are proper metal. These sport an iteration of the infamous "Koss wire", which is unusually and sometimes worryingly thin, and in this case, relatively short; the shortness of the wire suggest portable use but the lack of an in-line microphone/remote limit their practicality for many commuters like myself. The wire ends in a nicely sprung plug. Sound: These carry what you might know/have heard as "The Sound of Koss" - that is to say a sound signature that carries vocals, highs, and most acoustic-heavy music nicely, are relatively forgiving, and have rolled off bass. The soundstage beats most closed IEMs, which is expected as these are VERY open and offer extremely little isolation. However, unlike most open-back on-ear cans, these hybrid earphones bleed very little, even on high volumes, to the point that none of my colleagues 4 feet from my desk (in the office of the pre-COVID world) ever noticed the atrociously loud music I used to drown out the rest of the office. Extras: If you have the patience to wind these up properly, the included pleather carrying case does its job, albeit while taking up a good chunk of space. You'll get three pairs of ear clip bars, which you SHOULDN'T SEND BACK TO KOSS FOR WARRANTY REPAIRS, just the earphones. Speaking of the legendary Koss Warranty, these are covered and came back to me relatively quickly. What happened to mine, you ask? After a 6 month period of not using these earphones, I pulled them out of their case to find that the glue of the plastic driver housings on BOTH sides has let loose - both driver housings were open. I suppose the wire shouldn't be a concern after all...I love you Koss, keep being weird & wonderful.

Weird, good, and also weird
I bought these solely based on the fact that i could not for the life of me figure out how they would be worn. The design is very strange and I fell in love as soon as I saw them. Once you figure out how these actually work, you can appreciate the dual-driver sound quality delivered by them. Bass response is nice and boomy, and those secondary inner "tweeter" drivers deliver crisp highs and relatively defined mids. If you're looking for a weird earbud style headphone with good quality, I highly recommend these. But if you're impatient and not willing to do a little trial and error with something like headphones, I'd say your best move is to pass these up.

Warm with punchy bass and a.smooth roll-off.
Adjustment required often if you plan to wear while moving around. Sit and enjoy a unique sound from an old school mfg. who went with the design to achieve turning your outer ear into a funtional band pass enclosure.

The only way I can make these sound good is by gently pushing them into my ear canal and holding them there, if I don't do this they loose all bass and the treble overpowers everything. Its a shame because they sound great if you can get them in the right spot. I kind of wish Koss would use these drivers in a more standard form factor like an IEM chassis, then they would be amazing. If you are looking at getting these I would recommend getting the KPH30I which you can buy 3 of for the price of the KDE250.

great sounds great concept except ergonomic fittings.
very good quality sounds in many aspect. But to get it fit on your ear may be going too cumbersome. I spend 4hours at first time to find a sweet spot and then you will loose it when you do some activities that moving muscle on your face!

Nice One
The sound quality is good but is not comfortable for wearing it. I think this earphone is suited for Kross lover.

Interesting and overall acceptable, but probably better ways to spend your money.
I like all my other Koss products, I saw these as a novel type of headphone that I wanted to try. The handing of the position of the headphones to get them comfortable and sounding ok take a little bit of time and experimenting, and the way they sit in your ear makes it so they don't isolate very much and characteristically the cable feels thin/flimsy. In terms of comfort and sound quality they are totally acceptable, especially when amped, but at this price there are probably better things to spend your money on.
