Product Features:

  • Very substantial headphone at this killer price
  • Low cost yet durable, ideal for many applications including personal audio and commercial uses
  • Closed-back earcup design isolates from external ambient noise
  • Awesome manufacturer's lifetime warranty from Koss!

What's In The Box:

  • 1/4" full-size stereo plug adapter


We really don't know exactly how Koss can manage to sell full-sized sealed headphones at this truly bargain price, much less ones that actually manage to sound decent... amazing! The Koss UR-20 is perhaps slightly bass-centric, which is why its a good candidate for bass lovers. If you've know someone who is looking for audiophile sound performance in budget full-size, sealed headphones, we suggest saving up for some of our other recommendations like the Sennheiser HD205-II. However, there's no question the Koss UR-20 remains a really incredible value-loaded buy for folks on an extra-tight budget or for commercial headphone applications like schools, computer labs, doctors offices, and museums. The Koss UR-20 larger sealed-back earcup effectively attenuates a good deal of ambient/environmental sounds while preventing headphone 'leakage' from disturbing others nearby. It's also a comfortable wear, which comes in handy for long listening at workplaces or computer stations.

The Koss UR-20 are a composite-plastic sealed [aka "closed"] headphones with a size-adjustable headband and comfortable pleather earpad cushions. Although a bit large and oversize, they remain quite lightweight and ergonomic on the head given their dimensions. The UR-20 have an 8-foot non-detachable cord with a single-sided cable exiting the left earcup (no messy "Y" cord tangles!) and the cord terminates to a stereo 1/8" (3.5mm) 'mini' plug. Consider the similar Koss UR-29 model if seeking an identical-performing headphone but with a convenient 'built-in' volume control adjuster on the cord. A full-size 1/4" plug adaptor is handily included in the Koss UR-20 package. The sweet LIFETIME Koss manufacturer's product warranty remains in full effect, so just hang onto the receipt for free repair or replacement if they break. That's a way-cool warranty policy and only Koss does it!

Pretty Good For The Money
Posted by LazBro123 from Montreal, QC on 2011-12-10

Recommend Product: Yes
Pros: Good Value, Comfortable, Surprisingly Loud For The Money
Cons: Durability, Sound Quality, Distortion, Construction

I have owned the Koss UR20 DJ Headphones for a little more than a month. For the money, these headphones are pretty good, but if money doesn't matter, these headphones are not too great. If you don't have a lot to spend, these are one of the better headphones you can buy in the $20-$30 range.

Sound Quality: I must say that the lows and the bass on these are decent. It's deep and fairly strong. For listening to rap or hip hop, these sound pretty good, but that's just about it. The mids and especially the highs sound muffled and muddy. You cannot hear so much detail on these headphones and they are not too clear. It sounds like the lows, the highs and the mids are blended together, which means that there is close to no instrument separation. The bass is decent, but it is overpowering and it decreases the audio quality. 5/10

Build Quality: These are made out of cheap plastic and does not feel high quality, but $24.99 is understandable why the build quality is poor. The plastic hinges would fall off if you are not careful when adjusting the height of the ear-cups. I must say that these headphones are very flexible and you can move them anywhere you want and you will not break them. Construction can be better, but I love how these headphones are so flexible :D. 5/10

Comfort: There is not much to say about this. The cushions are very comfortable and fit on the ear very nicely. You can wear these for long periods of time without them hurting your ears. The headband adjusts to your head, so they are more comfortable. That's all I really have to say. 7/10

Portability: First of all, these headphones have no case. Secondly, these are the biggest headphones I have EVER seen, even bigger than the Monster Beats Pro. If these headphones had a case, than it would be pretty portable. Koss should really add a case. 4/10

Value For Money: For the money ($24.99), these headphones are pretty good.

Even though these are not that good, I have to recommend them because of the great value.

Best twenty dollars ever spent!
Posted by easyup81 from Chicago (Boystown), IL on 2010-03-20

Recommend Product: Yes
Pros: Damn good value, very comfy, twenty bucks for eighty-dollar sound.
Cons: A bit fiimsy feeling to *handle* (or adjust)

(So you know, I've had a pair of UR-20's for nearly a year. Used almost daily. So I've got alot to say.)

Honestly how much can you expect for$20 (plus shipping)? Well.....they're worth every penny. GIVE UP YOUR SPEAKERS. Your set of $400 5.1 speakers don't even compare. Plus you won't wake up your roomie. Got the full-ear for sound isolation. Honestly if your neighbor is loud as *@#! just move to a top-floor pad--full ear headphones won't really matter. But your roomates won't hear YOUR cheesy tunes with full closed ear phones like these. (Bonus)

These were my first new headphones in a while and, WOW! T-W-E-N-T-Y dollars. Still can't believe it. I had an OK 2.1 setup, but with the UR-20's I was able to pick our things I either couldn't hear or understand before. Probably the case with ANY headphone? Maybe. Read on (if you're not asleep).

Just get a pair. Hell, get two of them! SHARE THEM! (Before KOSS catches on and jacks up the price.) You won't regret it.Give as a gift--they say 'DJ' on the box. (ha!) They feel a little flimsy, but once you're wearing them who cares? The one-sided cable is to die for. They're big and soft.

No, they don't exude build quality--they *feel* like $20 headphones. Then you remember "that's what I paid for them!. Good range (for the price) and good volume. They won't squeeze your head off. Sound is a bit 'boomy' if you're picky about accuracy, but if you're going to be wearing them for hours on end and are on a budget they're a perfect fit They're almost a steal actually. Try them. Seriously.

If you don't go for it, don't return them--just try something else a bit better (and much more expensive) and keep the UR-20's as a good (bulky) backup. I prefer the slightly tighter sounding (and vice-grip fitting--ouch) Sennheiser HD 280's but gosh the UR-20's are comfy! Putting them on is like a relaxing trip to the spa.

Durable? Yes, actually. They're pretty tough--but they *feel* cheap. Break 'em? No biggie: TWENTY BUCKS, DEAR!

Portable? Not really--unless you like to look like a dork wearing giant headphones on the train. These are NOT DJ headphones (as the package boasts). Please!

Ugly? Yes. Ugly like you're dead uncle. These are probably the ugliest headphones ever made. Good news? You wear them AND YOU DON'T HAVE TO LOOK AT THEM.

They work nicely with non-amplified sources like iPODs or PCs (ie, more volume & less distortion) than most higher-end headphones without amplifiers. (Although the UR-20's do benefit from an amp for cleaner and louder sound.) They're a good buy at twice the price if you're not too discriminating on build quality. They're not *really* flimsy, they just *feel* like they are. If you want tight fit, better build and cleaner less 'showy' sound with an over-the-ear go for the Sennheiser HD 280 Pro's--at four times the price. (ouch). The UR-20's,in two words? "ULTIMATE VALUE."

Never owned 'non-bundled' headphones? BIG, ugly, soft, heavenly, punchy. Try these first. HIGHLY RECOMMENDED.

decent value but durabilty issues...lifetime warrenty not what you might think
Posted by anton from baltimore, MD on 2010-02-14

Recommend Product: Yes
Pros: cheap...decent sound...ok isolation
Cons: not very portable...cost as much to ship back to Koss as it is to buy a new pair

UR 20s are ok. They provide good sound quality for the money. But the pair i had literally fell apart from about 2 weeks of use. When I went to ship them back i realized it cost about 10 bucks to ship them back to koss + 6 buck for Koss to ship them back to you. That 16$ on a 20$ pair of headphones. I just too that money a bought a pair of Sennheiser HD 202 which are far more portable, give comparable isolation, better comfort, and give better sound quality (thought a bit more expensive depending on where you buy them).
