## Description

From the manufacturer The Original Stereophone For some, music is a nice distraction. A thing to tap your toes to. For us, music isn’t a thing; it’s a place we go. We are the true believers. Koss has been bringing people closer to the music they love for more than 50 years. The first Stereophone (SP/3) in the world was created by John C. Koss and Martin Lange in 1958 and since then, Koss’ innovative products have gone from strength to strength with a range now including Full Size Stereophones, On-Ear Stereophones, In-Ear Stereophones, Ear-Clip Stereophones, Wireless Stereophones and Communication Headsets. Now, more than 50 years later….Koss’ creation has become a $2 billion industry, worldwide. Three principles serve as the foundation for the company’s success: The sound of Koss; focus on fit and breakthrough customer service. What do these principles mean? The sound of Koss: Musician, John C. Koss created “the sound of Koss” in 1958 and we have stayed true to it to this every day. The sound of Koss brings music back to life. Koss engineers are rigorous in their pursuit of the absolute best sound but it is the human listening experience that sets Koss apart. 10-20,000 Hz Straight, Dual Entry, 4ft 16 ohms 112 dB SPL/1mW Limited Lifetime Warranty The Koss Plug revolutionised the world of in-ear headphones. A first of its kind, these are stereo, noise isolating in-ear headphones that deliver the kind of accurate acoustical reproduction and isolation typically found in high-end, closed-style high fidelity headphones. A dynamic element positioned just outside the ear connects to a tubular port structure that inserts into a soft, expandable cushion. The soft, foam expands for a custom comfort fit with every listening experience. It also improves isolation, plugging out ambient sounds and enhances deep bass and treble clarity. In addition, there are four additional soft foam ear cushions included in the box. The straight, dual-entry 4 foot cord will allow you extensive freedom of movement to ensure that you can position the headphones for optimum listening, making them ideal for workouts, gaming and more and the lightweight design enables you to comfortably carry them safely around your neck or in your bag wherever you go. Featuring a super sensitive frequency range of 10 – 20000Hz, a sensitivity of 112 dB and an impedance of 16 Ohms, these Koss Plug Headphones guarantee you a high-quality audio experience that will leave you anything but disappointed! This is all backed up by the Koss Stereophones Limited Lifetime Warranty.

Review: The PLugs - These are my third or fourth set of "Plugs", and I still can't see me buying anything else for commuting with. The Good points: Light, cheap and superb for rock music, you just need bass boost as they have the best treble response around! Classical and spoken are both nice and smooth. I'm lucky enough to have the right shape ears for them, and I've never had a problem with them falling out. The main plus point here is that with the right shaped ears, these really do shut out all extraneous sounds. The bad points are the cable and connector. I've had these with both the straight and right angle connector, and neither are as durable as I'd like, usually lasting 9-12 months. The other thing I find really annoying is the feel of the cable. Originally is was silky smooth, but recent cables have been relatively sticky. Who care's, I hear you ask? The cable sticks to your clothes, and mine keep pulling the plugs out of my ears! In all, though, these sound so good I won't give them up. They make commuting in London almost bearable.
Review: Perfect for me - I wanted some earphones that I could wear when riding my motorcycle. I had tried quite a few and all had their issues. I have to say these are pretty much perfect. The sound quality is good, I can turn my iphone volume down to 30% and still hear good sound at motorway speeds. This results in precious battery life savings. They go right into your ears and expand to fit, just like earplugs I would normally wear under my helmet to reduce wind noise, this means they stay in place when you put your helmet on and stay in place when you are doing pretty much anything. Finally, they cost a tenner...unbelievably good value. A couple of minor negatives The expandable foam does not last forever, and to keep a snug fit, the foam buds need replacing every few months (I wear them daily) One set of replacement buds is provided. As with a lot of cheap headphones, the wire connections are a bit flimsy, and one set has failed where the wire joins the jackplug, but the vendor agreed to replace them with no arguments. *** Update to this review April 2013 *** The cable has failed again at the same point, where it joins the 3.5mm jack. This is obviously a design flaw.

### ⭐⭐⭐⭐⭐ Good bass
*by L***U on 2 August 2024*

This is the third pair of these Koss earphones that I’ve owned over a number of years. They are a really good overall sound with excellent bottom end. Sturdy and comfortable to wear. Would definitely recommend.

### ⭐⭐⭐ Good headphones...BUT!
*by M***T on 9 April 2010*

I've owned four or five pairs of these headphones and I swore I would never buy any others. I find them incredibly comfortable and for the price, the sound is excellent. The problem is that Koss have recently changed the design of the jack and the cable is a bit flimsy. The last two pairs I have owned have stopped working in one ear after about 6 months. I have realy taken care of them, even unplugging them when i'm not using my ipod, so they don't get kinked near the jack. It's a real shame but I won't be buying them again.
