Koss T55959
Neodymium drivers deliver an 18Hz-24kHz frequency response, 16-ohm impedance, and 97dB sensitivity, producing clear treble and deep bass from a lightweight 50g frame. The flexible sling headband allows single-sided monitoring and withstands daily wear, while the 8-foot cord suits home stereo or DJ booth setups. Best for budget-minded DJs and casual listeners needing a durable, long-cord wired headphone, but poor isolation limits it for calls and gaming.

Resumen
The 30-Second Version
The Koss UR20 is a $19 over-ear headphone with top-tier comfort and a lifetime warranty. Sound is decent with EQ but weak in the mids and treble out of the box. Worth buying as a budget backup, but skip it if you need a mic or tend to break things.

Performance
The 18Hz-24kHz frequency response looks impressive on paper, but real-world sound is more modest. Bass has decent presence and the closed leather cushions help with isolation, but the mid-range and treble are weak out of the box. Several owners mention that a little EQ work brings out noticeably clearer sound. The 16Ω impedance means these run easily off just about anything, and the 97dB sensitivity keeps volume levels reasonable. The 3-meter cable is a nice touch for desktop use, though some users report it kinks over time.

vs Competition
The TOZO HT3 and Bose Bass BH1 NC both offer active noise cancellation and better overall sound, but they cost significantly more. The Truefree HF-10 and TALIX H30 are closer in spirit to the UR20, budget options with similar trade-offs. Where the Koss wins is comfort and that lifetime warranty. Where it loses is build quality and mic performance. The SoundPEATS Cove Pro offers better sound for not much more money, but you give up the Koss warranty and the proven comfort.

Value & Pricing
At $19, this is a no-brainer if you need a spare pair of over-ears for the office or a kid's first headphone. The lifetime warranty alone makes it worth the gamble. But the EUR 42-46 pricing in Europe changes the math completely. At that price, you're competing with headphones that have better build quality and sound. If you can get these for under $25, it's a solid deal. Above that, look elsewhere.
Price History

Overview
The Koss UR20 is a budget over-ear headphone that costs about as much as a large pizza. For that price, you get a surprisingly comfortable fit, decent sound isolation, and a lifetime warranty from Koss. It's not going to blow anyone away, but it's not trying to.
Our database puts comfort at the 88th percentile, which is the real story here. These things are light at 50g and the flexible sling headband does its job. Sound quality sits around the middle of the pack, which is honestly fine for a $19 headphone.
Common Questions
Q: Do these headphones need an amplifier?
No. At 16Ω impedance and 97dB sensitivity, they run fine straight from a phone, laptop, or any standard 3.5mm jack.
Q: Are these good for gaming or calls?
Not really. The mic scores in the 16th percentile of our database, so calls will sound rough. For gaming, the weak mid-range and treble mean footsteps and dialogue won't be as clear without EQ.
Q: How durable are these headphones?
The build quality is mixed. The overall construction is solid for the price, but the adjustment clip mechanism is a known weak point that several owners have broken. The lifetime warranty helps offset this risk.
Who Should Skip This
Skip these if you need a headset for calls or gaming, because the mic is one of the worst we've seen at the 16th percentile. Also skip them if you're hard on your gear, since the adjustment clips are fragile and will likely snap. And if you're paying European prices of EUR 42-46, you should look at competitors like the SoundPEATS Cove Pro instead.
Verdict
Buy these if you want a cheap, comfortable pair of wired over-ears for music listening at a desk. The lifetime warranty and solid comfort make them a great backup pair. Skip them if you need a mic for calls, since that's the weakest area at 18.2/100. They're also not ideal if you're rough on gear, because that adjustment clip will snap on you.
