Was there the activation code for lifetime waranty somewhere that I have missed? Because I cannot find it now. Or does it not apply when the item was bought via Massdrop?

The cable tore at the junction after three months of use. After reading some reviews it seems the cable is a common source of issues.
Wow, in looking at the discussion mine also arrived with the Earphones and case looked used. Good news is that Massdrop did refund me but I wanted these for a trip I was planning on and looking forward to using and unfortunately no replacement was offered. :( I had to waste my time in getting these returned. Quality control has been an ongoing issue with Earhones / Head phones... with Massdrop. Hopefully things with start to turn around.
I bought these when they first came out almost a decade ago... Fit wise, you need a large and wide anti-helix so they can get down into the bowl of your ear deep enough and yes, fit the smaller piece inside of your ear canal.

It would be cool to see this active again and maybe grab a pair for old times sake. I sold mine after getting a TripleFi10 that sounded clearer.
i really want to jump for these drop but the price is really intriguing its not expensive what i mean

but the price in my country indonesia anything above 100 usd will get tax about 30% from the price

this koss 99.99 with 2.86 dollar shipping that make this priced

can i ask for invoice to be below 100 usd ? like 99-98 usd /? pls ??

so i don't get hit by huge tax please !!! any massdrop or koss employee can help me ?
One of the best sounding open compact earphones you can buy!
If they fit to your ears, of course)
Indispensable for travel, when traveling only with hand luggage and tired of IEM or would like to hear what's happening around:
- Knock-knock, it’s a made, here is your Glenlivet!
The Koss earphones arrive without the earphones.

i hope you got refund
I have given up on trying to get these to fit and stay in place while walking or working out at the gym. I've tried all the ear pieces and adjusted the height......to no avail. Terrible design. Sound is great is a 10 and fit/comfort/ease of use MINUS 10.
Wtf? Was this only available for a week?
After all the reviews I wish the price would have gone lower, then I could've considered to join in, but I think I'll have to pass on these as most people seems to be avoiding it. :( Only if the price were around 60-70ish.
I'm dumbfounded by people here saying they don't like these. I have pretty high standards: the WORST headphones I use on a daily basis are HE500s, and that's only when I'm tired of my Alpha Primes and my Stax Lambda Pros. I don't think very highly of dynamic drivers in general, but the KDE250 here is one of only two dynamic driver sets I actually like (the other is a Sennheiser MX985).

These 250s legitimately compare with the TOTL Audeze iSINE20. They don't sound as good as the 20--does anything this size?--but they come impressively close. I actually sold off my 20s because the 250s are close enough in terms of overall SQ, and are actually BETTER for portable use. The iSines are really unforgiving of bad sources, they will show you all the flaws in a recording, but they scale up with better equipment beautifully. The KDEs, OTOH, sound great even from a smartphone's headphone jack. The Koss won't scale nearly as high as the Audeze can, but they do still improve pretty significantly on my desktop rig.

For reference, my desktop rig is a Schiit Mimby/Magni stack. When I'm not at home I sometimes listen just out of the headphone jack on my V20, other times I'll carry a Hifiman HM601 or an ODAC/Fiio e11 stack with me (which actually rivals my desktop stacj in SQ). I listen to EDM, hip-hop, and occasionally rock.

Honestly I question whether people like jamtato below me have actually heard a KDE250 before. I can certainly understand disliking them based on fit or comfort or aesthetics, or maybe they aren't a good match for your specific use-cases. The 250s can be sensitive about where exactly they fit on your ears, because there is a definite "sweet spot" where they sound their best, and they sometimes require frequent adjustment to keep them there. I understand all that, and those are valid concerns. They aren't appropriate at all for runners, for example.

But people are complaining about the SOUND??? It's one thing if they simply don't match the sound signature you prefer, which I suspect may be happening, where idiots confuse subjective opinions with objective performance, or contrive the latter to make themselves feel better about feeling the former. I think the HD650 sounds like complete shit, personally, but I don't go around telling people that it sucks or that it sounds tinny, because it fucking doesn't. And neither does the KDE250.

I can't help but notice that NOT A SINGLE ONE OF THEM actually recommended an alternative that they consider better.
I remeber when I first tried mine with the medium earhooks They DID have rather forward lower mids, it was almost too annoying. But after a while I dicieded to try the small hooks and in addition to a more secure fit the mids got considerably more in line with the rest of the range and I now find the KDE250 highly enjoyable, It's definitely a very unique earclip/earbud type of headphones.
There are better for less money. Some Koss phones are great but this type of phone has come a long ways and Koss has not kept up.
If you have one for sale - let me know here or at email - mr-king@bk. ru

They are for sale right here, what are you talking about
They might not ship to Russia, where he lives.
These have been burning in for 20 hours, and so far I hate the sound. They are very comfortable. Very (for me). But the highs are horribly harsh. Overdone, tinny, almost like they are being projected through a long horn.
Does it get better? Please tell me it's going to get better. Or that I'm wearing them wrong.
I've seen the advice here to not push them deep into the ears, and that helps, but no matter where I place the drivers (a millimeter of change at a time), the sound may change, but it's never audiophile-grade.
I hope it gets better...
After a few days, it's getting better. The highs are more natural, transparent and very clear. Voices still sound a bit hollow, but I'm hopeful that will clear up as well. Ear placement is very finicky still. To adjust the sound, try rotating the emitter angle up and down, as well as using the hinge to angle it in and out of your ear.
A couple months later, voices still sound a bit like they are being sung through an old-fashioned paper megaphone. The bass is good — especially good for such an open design. All the highs are there, but a bit harsh. There's a lot of detail if they are perfectly positioned in your ears, and they are very efficient — I have to turn the volume down vs my on- or over-the-ear headphones. The vocal zone is still harsh and has that "through a horn" quality that makes long listening sessions tiring (though physical comfort is fine). But I claim to have golden ears and I'm VERY picky. You may not be bothered by this. I am tending to choose other headsets over these for both casual and critical listening. They are nice in the summer, however, since there's nothing to get all sweaty.
