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 eight foot cord. A gold-flashed 3.5mm (1/8") plug, L-shaped to minimize cord stress is included.The UR40 will delight listeners seeking heavyweight sound in a comfortable lightweight package. Home and portable audio take on fresh life with quality headphones, and Koss's lightweight, closed-ear UR40 is designed to keep outside noises out and headphone sound in--perfect for use in busses and libraries alike. With its extended frequency range of 15 to 22,000 Hz, you'll never miss a single bass note or want for high-frequency splash or shimmer. The UR40's titanium driver elements ensure taut low end and clear treble, while its collapsible headband design further lends it to portable applications and protects the headphone when not in use. The headphone comes with a four-foot, dual-entry cord and a .25-inch stereo adapter for use with hi-fi components.What's in the Box Headphones, adapter plug, user's manual, warranty information.

    • How Do You Hear?
Product Packaging: Standard Packaging
There is a wide range of hearing acuity for humans. I am very critical because I am a musician and want precise audio detail and have also started to loose my high frequency hearing ability. I returned Sennheisers which were inferior to these and twice the price. I am returning Koss QZ99 headphones which were inadequately described in the sales ad. The box states they are for scanners and metal detectors (not stated in the ad) and the low frequencies are almost non-existent. These UR40 headphones are just barely good enough for me to keep. The VERY BEST Koss product is the KSC21 Sport Clip followed in second place by the KSC75 which have a wider frequency range but a less dynamic presence than their less expensive counterpart. I have used a hot knife to stabilize the ear clips from moving on my KSC21s so they are always comfortable and fit my ears precisely every time. I have also removed the pads on them for ease of fitting and the fidelity is just magnificent. The KSC75s are larger with a nicer ear clip which you can bend to adjust but they do not perform as precisely as the KSC21s. The only reason I am keeping the UR40s is that they are much quicker to get on and off when working with sound qualities and performance with various units and musical examples for study and learning. Overall, Koss is the best out there in my opinion. ... show more

    • Great Intro to Open-Back Headphones
Product Packaging: Standard Packaging
Bottom Line - These are much more durable than they appear, are easy to drive (can be run on any device, without an amp) and give you an excellent introductory listen into how Open-Back headphones sound. ------- Long Story - I've owned these headphones for 2.5 years now I started looking into open-back headphones for gaming, because I needed to be able to hear directional detail (imaging and soundstage) in my game while ALSO being able to hear my buddies talking to me in the same room. I wanted to get Sennheiser HD 598, but it was an awful steep price to pay for something I wasn't sure would solve my problem, and I also wasn't sure how loud the sound would be from the headphones for others around me. So, I looked for a cheaper open-back headphone to try. These KOSS UR40 headphones were the cheapest option I could find with reasonable reviews (at the time), so I bought them. The first day, I was convinced that Open-Back headphones would solve my problem - they're basically transparent, I can hear everyone talking to me nearby (when ingame noises aren't overpowering), but the noise leakage isn't THAT bad (especially if my buddies also have headphones on). Bullets wizzing by certainly leak very loudly... but that's not bad information to have leaking in my scenario anyways. So, I immediately turned around and bought those Sennheiser HD 598, and brought my KOSS UR40's to work (so I could have headphones on w/o ignoring my coworkers). For the past 2.5 years, I have used these headphones all day, every day, 5 days a week at a (mostly) desk job. I very frequently take them off and fold them (clicking the little plastic-lever headphone lock) - probably take them off and on again 20+ times a day. The use case is VERY heavy, extremely regular and consistent, but not abusive. I can say that they have held up wonderfully - the only thing that has broken is one of the 4 rubber rings that hold the head-strap on, and that appears to be replaceable, but the headphone and strap work fine with just the remaining 3, so I haven't bothered. There's not much to be said about the sound quality that others haven't also mentioned (probably, I haven't read the reviews). The bass is lacking next to the V-shaped closed-back bass cannons most people are used to, but the quality of sound is good and detailed for the price. They work as headphones, and are very transparent, so if you're wanting to dip your toe into the world of Open-backs, I highly recommend! To be honest, I don't know if I will replace these when they break with new UR40's or not... because I used them as a jump-off point for Sennheisers, I think I've spoiled myself. I have a collection going for HiFi headphones now (like HiFiMAN, more Sennheiser, Beyerdynamic, etc...)... but those are a bit expensive to leave on my desk at work, so I will certainly consider these UR40's again, but will be weighing them against other sub-$100 sets. (NOTE: I was asked to "Rate features" and one of them was "Noise cancellation" - Firstly, these are the opposite of noise cancelling... they are transparent... and that was the point for me - Secondly, I wish "Noise Transparency" was the real question, because when I do replace these at work, the Number 1 question I will be wondering is, if those other cheap open-backs are as transparent or not... seems I won't know until I buy them...) ... show more

    • First Open Backs Review
Product Packaging: Standard Packaging
Review Image by Ariana Phouangkeo Ariana Phouangkeo
Disclaimer: I am not an audiophile by any means, I just enjoy sound and music. I ordered these headphones on a whim because they were Open Backs at a very good price for entry ($33-$40). The appeal was for a very wide soundscape, fantastic for Large Scoped Movies or Immersive Games. Sound: (Let's be honest, sound is pretty subjective, but I'll try to be as objective as possible) Starting with the most important aspect, the sound reproduction is above average based on the price range. Base sound, it leans a bit on the lows however, the mids and highs are definitely not extenuated enough, so it doesn't sparkle when you listen for it. I fixed this though by tweaking the equalizer to have a little more highs and it sounds a million times better for it. "But what about that "soundscape" you ask? Well, It does a phenomenal job at doing it. First thing I had to try was Modern Warfare 2019, and Ground War sounds amazing in general with expanding the scope of the sounds. Vehicles, distant explosions, overhead helicopters and gunshots, it all was fantastic. Then I watched The Raid 2 with its very brutal but detailed sound effects with little music to distract it all. Also fantastic. Like a home theater for your ears. It really is a lot different than closed back headphones, or IEMs that I have tried. It really is something you have to try yourself if you haven't because for an entry, it has me wondering how it can get better from here if I just paid a little bit more. Build: The whole frame is very flimsy admittedly. Its all plastic, no metal components except the drivers. They are not stiff though so they can easily form on your head. It feels very light and almost like its not even there which is a plus. Ear pads are not good though, almost gives the impression that its on-ears and not over ears as advertised. Alternatives do exist though online. The wire is also pretty bad, like dollar earbud wires. They also aren't removable to note. They connect to both ear pieces instead of just one ending in a standard gold connector. Other notes: Just to say, since they are open backs, they are meant to bleed out sound as by design, and any sound in the background will come in. So have a quiet place to listen to the sound. I'd say for how much they are, they are definitely on the better end of this price range. ... show more
