Awesome Sound AMAZING Bass
by moonoverhaddath-21508621637107 on April 4, 2007
Pros: Handled Anything I Threw At It, Bass, Treble, Trance, Rock, Etc, AFFORDABLE.
Cons: None Just Yet, But I've Heard None.
Summary: I just bought these, and I must say I was just typing an e-mail... when all of a sudden I became aware of every SOUND, trough and crest of every ...
Summary: I just bought these, and I must say I was just typing an e-mail... when all of a sudden I became aware of every SOUND, trough and crest of every musical note in the song.
These headphones rock my socks and I want NO OTHER.
Very good. Very very good. Koss lives up to its name.

Biggest sleepers in headphones
by caponsacchi on November 26, 2007
Pros: Pristine sound in lightweight convenient package
Cons: Webbing breaks, cord too thin and short

Summary: These are my cheapest phones, but I use them more than any others, including a regular radio show on our NPR outlet. They're handy to fold up and toss into a bag and then to slip on, and as lightweight as they come, yet the sound has more "presence," bite, brightness and depth than Sennheisers, Sony's, and other Koss's costing 2-4 times the price. They're obviously designed as personal phones for the younger listener on the go. The head webbing will soon break loose, and the thin short cord be a concern, but they're a steal at anything below $40. They've spoiled me. The other phones are either too heavy with "distant" sound or too "fussy" (like folding the Sennheiser PC series--too time consuming).

Simply amazing headphones.
by Golden Helmet on April 1, 2007
Pros: INCREDIBLE sound, good price, most comfortable audio device I've ever used.
Cons: Bit of a hiss in the audio when the song is quiet, the cord is a bit short.

Summary: I used to have a cheap (but incredibly nice) pair of Cyber Acoustics headphones, and they served me well for many years. But then they broke, so I've been using earbuds for a long while now. Oh the pain.
These headphones completely dominate every other earbud or headphone set I've ever used. The sound quality is about as good as it gets, their comfortable, they fold up, they swallow up your ear, and they drown out almost all outside noise (with decent volume on your audio of course). The bass on these is amazing, though not overboard. Perfect balance.
My only complaints are that in parts of songs where it's quiet, there seems to be some hiss at moderate-high volumes, and the cable is short. Give is an extra 2-3 feet or so to the cable, and I'd be even more happy.
For MP3 players, portable DVD players, or even gaming (if your PC \ audio connectors are close), these can't be beat, especially for their price.

Great headphone for the price.
by MRubillo on April 25, 2006
Pros: Reasonable price, comfortable fit, crisp sound, good base.
Cons: My only complaint is the cord length. Needs to be at least 2 feet longer.

Summary: I did an extensive search for headphones and have found that there is a wide range to select from and that the type you chose should really be dependant on what you are looking to do with them. I am a consultant and do a lot of traveling. Therefore I needed a set of headphones I could use with my laptop, that could fold for traveling, and are good for music, games, and movies. The Koss has fit that bill perfectly. The sound is crisp with good bass. I have had them on for up to 4 hours straight and they never became heavy or uncomfortable. The head band works surprisingly well. After such a long period of time I did notice they were hot but I think any headphone would be. My only complaint is the cord length. Since I barely notice them when I have them on I have slide my chair back a few times with the headphone plugged in and yanked on the cord, computer, and my ears pretty hard. Give me at least 2 more feet and I would be giving these a 10 out of 10.

Very Good Sound Quality a Very Good Package
by MrEbert on July 21, 2009
Pros: Very comfortable on head, Lightweight, Collapsible for portability, Extremely good bass, Clear and defined sound, Low price
Cons: Construction feels a bit flimsy, Almost no sound deadening (incoming or outgoing), Easily shift around on head, Quite a large set of headphones
Summary: In terms of sound quality, these headphones are extremely well made. They provide an experience in which one doesn't really notice he is wearing headphones. The UR40's rest ...
Summary: In terms of sound quality, these headphones are extremely well made. They provide an experience in which one doesn't really notice he is wearing headphones. The UR40's rest comfortably and lightly on the wearers ears, hardly applying any pressure on the ears. However, this impressive comfort means that there is pretty much no sound deadening for outside noise. Ironically, there is no deadening in the other direction either, meaning anyone and everyone around you can hear exactly what you're listening to if the volume is turned up even a bit. This is not a huge problem whatsoever, but should still be mentioned. The sound quality is definitely the UR40s' strong point. Bass reproduction is fantastic, quality I've only heard before on professional studio monitor headphones. The rest of the range is also fantastic in terms of quality, with clear mid range along with crisp (but not overpowering) treble. In a nut shell, the Koss UR40 headphones offer excellent sound quality all around, in a lightweight and portable construction that rests gently on one's head, and provides a wonderful headphones experience.

Most under-rated open, dynamic headphone.
by timlanders56 on September 21, 2013
Pros: These very inexpensive open-air style headphones (the design allows sound to enter and exit the ear cup, creating a more transparent listening environment) are the closest thing you'll find to an audiofile type Headphone experience for less than $50.
Cons: All plastic, somewhat flimsy design must be handled carefully, short cable connected to both left and right cups is a pain but not a deal-breaker.
Summary: If you have a hankering to experience an open-back headphone but don't want to shell out the big bucks for Sennheiser or Grado cans then you can't beat ...
Summary: If you have a hankering to experience an open-back headphone but don't want to shell out the big bucks for Sennheiser or Grado cans then you can't beat these inexpensive Koss UR40s. I bought mine a few years back while on tour after a pair of Sonys crapped out and was very much surprised at the audio quality of these cheapos. I find myself using them more often then my expensive closed-back sets (I own a recording studio). I even check my mixes with them! As a result of getting these, I'll probably invest in a higher quality open-back pair eventually like a Sennheiser or Grado, but for now these guys are sounding pretty darn good. Highly recommended for the price.
sounds good but it is broken
by cat7510 on November 19, 2010
Pros: good sound
Cons: 4 out of 3 little rubbers broke long time ago. They were holding mesh onto a body. It will cost over 1/4 of price to ship it to the manufacturer plus necessary trip to the post office and wait for 3 weeks. I would not get them again.
Sounds great----OWWW MY EARDRUMS!!!
by Deathyak on February 21, 2010
Pros: Amazingly crisp treble. Good bass. Light. Open feeling.
Cons: Feels like my eardrums got attacked with a cheese grater. They have no weight. They apply no force and slide around. If they're not centered, they don't sound right. They don't stay in place either. Sound leak?
Summary: These are really amazing headphones. They sound amazingly clean and are quite cheap. I got them free from a friend because they needed to be rewired (which I did with ...
Summary: These are really amazing headphones. They sound amazingly clean and are quite cheap. I got them free from a friend because they needed to be rewired (which I did with some dollar store headphones)sound leak isn't really an issue. You'd only hear it in normal situations if you're listening for it. Then again, I'm used to people playing ipod earbuds so loudly you can hear them from +5 feet away.
Rewiring them was easy. They're really light and feel like they should be really comfortable because they apply almost no pressure...but something's just not quite right.
These sound great, then after 2 minutes, I felt a little queasy. After 5 minutes, I had a headache. After 20 minutes, I threw them across the room, gave them back to my friend for free and yelled , "OH GOD THESE THINGS SUCK" really loudly on my bus.
They're really good headphones ruined by the fact that it takes under 2 minutes to get listening fatigued. This makes them HORRIBLE headphones. They have pretty good spacilization and clarity, but its TOO real. I took them off and felt deafened because I no longer felt the overly defined treble in my ears.
No. *grabs skullcrushers while multiple audiophiles cringe in fear*

These do sound pretty good around your neck though. Just turn them up all the way and you get pretty good stereo separation!

- Description: The UR40 delivers digital quality sound in an ultra-lightweight design for listeners on the go. The UR40 features dynamic elements for a wide frequency response from 15-22, 000 Hz. A 2 mil. titanium coating on its diaphragms increases the rigidity of the elements, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Computer-optimized neodymium iron boron rare earth magnet structures enable the UR40 to deliver greater volume, even with low-voltage portable devices. Oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. With its hybrid design, the UR40 combines the best of closed-style and open-style headphones. Closed leatherette earcushions form a light seal around the ears, enhancing bass frequencies. Screened earcups provide an open, hear-through sound that lets listeners stay in touch with the world around them. The result is a full frequency, clean sound that turns any recording into a "live" performance. At just over six ounces the UR40 wears comfortably even after hours of continuous listening. The airy mesh sling provides soft breathable support, ideal for those with touch-sensitive scalps. An adjustable headband accommodates all head shapes and sizes for maximum comfort. When not in use, the resilient, lightweight frame folds into a compact configuration that's protective, easy to carry and convenient to store. Perfect for travel, the UR40 includes a straight dual-entry four-foot cord. A gold-flashed 3.5mm (1/8") plug, L-shaped to minimize cord stress, and a gold-flashed 6.3 mm (¼") adapter are included.
