## Description

Product Description The Original StereophoneFor 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.Focus on fit: We are obsessed with creating the absolute perfect fit – without it; we can’t get the perfect sound. We strive to create products that offer custom settings for every music lover. Our products couple to the ear – it’s just you and your music.Breakthrough customer service: Koss was the first to offer Limited Lifetime Warranty in 1989. Our domestic customer support staff is ready to help any listener with any issue. The Koss US factory and warehouse is based in Milwaukee Wisconsin – logistically, Koss has created an onsite inventory system that makes “out-of-stocks” virtually impossible. With all this is mind, what specifically do Koss Sporta Pro On-Ear Headphones have to offer you?The Koss Sporta Pro On-Ear HeadphonesThe Koss Sporta Pro are the perfect headphones for an active listener who needs to move from the living room to boardroom to locker room without missing a beat. Combining the sound reproduction of the Koss Porta Pro with a unique design that allows over-the-head or behind-the-head wearing, the Sporta Pro won’t interfere with hats or hairstyles – a prime portable headphone.With Mylar elements ensuring the accurate sound reproduction and minimal mechanical distortion, Koss Sporta Pros are lightweight headphones that also feature computer-optimized rare-earth magnet structures (neodymium, iron and baron), which deliver uncommon sound clarity no matter what volume you listen at – even with low-voltage DVD and MP3 players.The Sporta Pro’s have numerous details for comfort; to name cushioned pads, foam ear cushions and multi-pivoting ear plates, all of which enable you to stay in touch with your surroundings. To add to that, the fantastic oxygen-free copper voice coils improve signal transmission for a clean, crisp sound, so you can listen to your music in its full glory.At a mere two ounces, Sporta Pros feel practically weightless, even after hours of high fidelity listening and the straight, single entry 5 foot cord 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. When not in use, simply collapse them down into a compact protective package and tuck them into your briefcase, gym bag or backpack on your way back to the office.This is all backed up by the Koss Stereophones Limited Lifetime Warranty.So whether you use the Sporta Pro On Ear Headphones at home, at the gym or elsewhere, you’ll always enjoy exceptional comfort, unparalleled durability and most importantly, a deeper connection to your music through the Sound of Koss. Manufacturer's Description The SportaPro is the perfect stereo headphone for music lovers who need to move from the boardroom to the locker room without ever missing a beat. Combining the same amazing sound reproduction capability of the Koss Porta Pro with a flexible headband design that permits the listener to wear it on top of or behind the head, the Sporta Pro is the perfect accessory for music lovers on the go.Dynamic elements deliver deep bass and a wide frequency response from 15-25,000 Hz. Extremely rigid mylar elements ensure accurate sound reproduction and minimize mechanical distortion. The SportaPro features computer-optimized neodymium iron boron rare earth magnet structures to deliver great volume so you can hear every detail in your favourite movie or tune even with low-voltage DVD and MP3 players. Oxygen free copper voice coils improve signal transmission and conduction for cleaner, clearer sound.Perfect for the active listener, the SportaPro's unique headband design pivots backward at its base, easily converting from over-the-head style to a behind-the-head style that won't interfere with hairstyles or headgear like helmets or baseball caps. Foam earcushions rest comfortably on the ear and provide an open, hear-through sound that keeps you in touch with your surroundings. Cushioned pads at the temporal bone diffuse pressure away from the ear for a uniquely comfortable fit. The adjustable headband with multi-pivoting earplates accommodates all head shapes and sizes and stays in place even during rigorous activities. At a mere 2 ounces, the Sporta Pro feels practically weightless even after hours of listening. When not in use, the Sporta Pro collapses into a compact protective package that tucks neatly in a briefcase, gym bag, or backpack. For maximum portability, a carrying case with drawstring is included. The Sporta Pro includes a straight single-entry four-foot cord. A gold-flashed 3.5mm (1/8") plug, L-shaped to minimize cord stress, is included.The Sporta Pro is ideal for active music lovers motivated by an excellent sound performance with deep, rich bass.

Review: Great sound and comfort at a bargain basement price - I bought these after reading reviews of them and other Koss products. These are great headphones that are among the best I've used for a long time. Sound: Quite simply excellent, and for the price I have not heard better. The range of tone is brilliant, giving strong and clear bass without sounding muddy. Treble coming through bright and rich without any tinniness. This sound quality is something lacking on any other lightweight headphones I've used. Even when turned down to a low volume the sound is still bright and healthy. I'm no audiophile, but I've been seriously impressed by these headphones Comfort: On the ear type, foam covered earpieces. Nice and light with a secure fit. They can be worn as either over the head or behind due to the movable adjustable headband. As a sports style headphone they hold themselves on the head firmly, so no bother when you're getting a bit active. Construction: Seems good, I can't find anything in them that looks like a weak point. They can be curled up, folded in, and clipped together for stowing away. With a lifetime guarantee too, who's going to grumble about that. Look: Lets be honest now... there are more stylish options out there. But as I can't see them when they're on my head I don't mind much. Extras: 1\4" jack plug adapter and a stash bag. Overall: For less than £20, I have been really pleased. Strongly recommended.
Review: Light weight with good sound - great for workouts. - I purchased these after doing research on headphones suitable for sports and workouts, particulary running. My ear buds were not suitable for long runs as they would often shift in my ear and eventually fall out. This became especially bad as soon as I started sweating. I wanted headphones that would stay in place and were lightweight, and with decent sound. After doing 2, one hour long runs with these, I can happily give them top marks. They can be worn with the strap behind your head, or on top of your head, with equal comfort. This is because they are very light, and because the strap exerts some pressure to keep the ear pads on your ears. They stayed in place throughout the runs (thread the cable through the neck of your shirt and you won't even notice it is there!). Even though the foam pads do get wet once you start sweating, you really don't notice is as you are obviously wet first. They dry out quickly and seem to be holding up fine. As I am using these exclusively for sport, I was not looking for the best sounding headphones. That being said, these absolutely kill the sound out of the ipod ear buds I was using previously. The difference in the bass is significant, so you will have much better sound quality with these than standard ear buds. Are there better sounding headphones out there? Probably. But these do sound really good even if just chilling out listening to music at home. Finally, throw in the carrying case, the Koss lifetime guarantee (which I hope to never use, but have heard rave reviews about), and the low price, and you have a 5 star product!

## Questions & Answers

**Q: What is the hz range**
A: The range is 15 - 25,000 Hz.

**Q: I want to use this headphone in combination with an equestrian communication system. How long is the wire?**
A: I bought mine about 8 years ago and they have really lasted well, but the length of the lead may have changed with newer models. The total length of the cable is just about 48 inches. However about 36 inches from the plug, the cable splits in two to go to the two ear pieces - if you are with me. I used these in a gym and used to have the cable running over my shoulder to my ipod clipped to the back of my shorts, and the cable was just the right length. I would just add that in my view -these are fantastic headphones.

**Q: I want to use these to listen to audio books while in bed- is there much sound leakage?**
A: Shouldn't think that audio books would present much of a disturbance. The levels would be much lower than with certain types of music. But one must bear in mind that these headphones are open backed. I have a couple of pairs of these, one over fifteen years old. Possibly the best headphones you can get for the money.

**Q: I've heard Porta PRO and Sporta PRO are just different design choice but same speakers, can you approve that?**
A: Yep I've had both of these phones stripped them down (to relpace cables) & they use the same drive units just buy the cheapest version you can

### ⭐⭐⭐⭐ Better than photo looks
*by R***Y on 29 June 2016*

I like them,cant remember them costing as much last year, but they are well made and comfortable to wear , sound good too. They have a fold back feature which i like. I think they look better than the picture and darker. I would have them again at the right price, which rates them as a good buy, mind your hair, it can get caught at the to Sound good, worth a try, a bit different. Lasted over a year so far, so stronger than they look. Now, where did i put them.
