OK everyone, I went shoping for a headphone just like you guys. Although there are differences in headphones, $100 and below will not contain much difference as the manufacturer would have you believe. The technology is there to make great phones cheap. Seems gimmicks are the stay of the day (remember those rare magnets in the 80's?), and now the pretty colors. Gona goo goo ga ga over colors and how you got the neat rare magnets?, or are you gonna listen to it? The most useful invention to date has been the behind the head headband! I always wanted to to that to my old phones! The specs are impressive at 15-25,000. The human ear can hear 20-20, but if your 31 like me, 25-15 is more like it, lol. The bass is stunning and defined and the highs are not shrill and nasty. The phones are comfortable and efficient. Unless you can spend $250 for Grados, then you will not notice the $ difference. I use them for my HIPZIP MP3 player and my port cd player. These things are just plain wonderful for $30. If you cant find them from a major dealer, RADIO SHACK markets these under the PRO45 model. The plug even says KOSS. They tend to be cheaper there also. Surely you have a RAT SHACK? Now get off your butt and take our advice, and save a load of cash for some wine or something, ok?

These pair of headphones are in there 5th year of use...and are still bumpin' strong. I bought The Porta Pro Jr. in 1996 for use on everyday CD players, and they have outlasted 3 CD players to date! To give u an idea of how tough these cans are...I Jog with them, SWEAT on them, SLEEP on them, steped and sat on them, Crushed them in school backpacks, lend them to friends, and traveled with them. Now tell me, how many headphones could withstand so much moisture, abuse, and time as these.
The only time i had problems was around the 4th year of use. The right driver started to crap out on me, the wires began to fray because i have a habit of chewing on them when studying, and the plug started to come off from years of tugging and pulling during my workouts. But not to worry. THE LIFETIME WARRENTY is rock solid, if you don't believe me go to their website and call up customer service. They will be glad to take them back no matter what you have done to them...and they will replace it for 5 measly dollars in exactly 3 weeks. I returned them once and it came back BRAND NEW. They said they couldn't repair it so they gave me a new one. UNBELIEVABLE!!!
Now about the sound...with any CD player, your listening standards will match those of studio quality and build. I listen to a variety ranging from Classical, to Jazz, to Gangster Rap, and Techno. The Bass is Well balanced, ROBUST, and tight with definition. The midrange is unbelievable crip and precise, especially with classical music. And the Treble is crystal clear and SMOOTH. The experience is like listening to a 3000 dollar home theater from Mirage speakers...i know cuz i have one! Usually headphones are heavy on bass and heavy on treble and lack midrange...This headphone does it all!!! Regular headphones usually lack definition and are sometimes made JUST TO MAKE NOISE.
OH! another feature that may interest you is it's ability to detach it's headphone drivers from its headband. I have repeatedly removed these drivers so that i may share them among my friends @ college and they are amazed at the sound by just one driver! They have never broke on my from this type of use either...so don't worru about taking this baby apart, it'll just snap back together!

Just like how Boston Acoustics specialize on speaker making and how BMW specialize on top notch sport sedans...THe Koss company ONLY specialized on protable audio equipment and mainly on headphones...so you know that this headphone is made for quality. Visit their site today! www.Koss.com

Folding is pretty cool

Too tight, too much bass, too heavy for me

Hi folks,

I got the PRO-45 from RS, which to my understanding is a Koss Porta Pro Jr. I've only had it for a few hours and I'm not very happy with it. I'm comparing it to a $10 KOSS KSC10 which sounds much better to me. The KSC10 is also a bit lighter and more comfortable, which is ironic because I bought the PRO-45 because I expected it to be more comfortable due to the adjustable band.

The main problem I have is that the PRO-45 sounds muffled when compared to my KSC10 which sounds much more breezy and has a nice crispness to it. Also the bass is just way too much for my taste, it's all I can hear throughout the song.. and becomes painful even with lower volume and bass settings. I'd be really happy with the KSC10 but for the fixed band which makes it difficult to rest your head on a pillow because it is too large, also the band's stiffness makes the pad's position hard to adjust for a good seal.

Not sure what I'm going to do, but I believe I will take the PRO-45 back. Maybe I'll just put some foam on the KSC10 to make it more comfortable. The more I play with these two, the more I appreciate the KSC10 which for $10 is a heck of a good pair. I think I'll try to twist the pads overnight and see if I can line them up better.

For the price this is a great headphone. I've purchased more expensive speakers that sound dull compared to the Koss Porta Pro Jr. Previous headphones only lasted me 6-12 months (jack and cord damage) but these babies have now lasted me over 6 years.

the koss porta pro are a great set of mini portable headphones. i have not heard any mini that could match the sonic fidelity of these phones. they are virtually the same as the porta pro's (the transducers are the same), the only difference being the lack of a comfort adjust feature (which isn't really worth the extra money). they are bass heavy, but not in a bad way. recommended.

Portablity, sound and price

appearance

When searching for replacement headphones for portable players, perhaps the biggest challenge is to find something that sounds good, retains the portability and doesn't cost a fortune. The Koss PortaPro Jr. delivers on all three of those criteria.
Number one, they cost just 30 bucks.
Number two, they are small and fold up to become even smaller.
Of course, 30 dollar headphones that fold up are worthless if they don't sound good, right? Well these babies DO sound good. In fact they sound better than anything should that costs 30 dollars.
The bass can sometimes be too boomy depending on your bass boost levels. But overall you get very good sound from these little headphones.
I've been looking for the perfect set to go with my minidisc for the last several months. I've tried everything from the Sony 888 earbuds(not bad for earbuds, but not great) to the Radio Shack Pro25(almost as good as the PortaPro Jr. but TOO uncomfortable).
The PortaPro Jr.s are the answer to your portable music prayers. They are extremely comfortable, sound damn good and cost $30. What more could you ask for? Oh I guess Koss could redesign them to make them more asthetically appealing but that's nitpicking.

These phones are the so-called Jr version of Koss's Porta Pro. However, the only differences between them are the absence of adjustable temple pads and a thin plastic carrying bag with the "Jr"; otherwise, the acoustic properties of the units are identical - and hardly worth the extra $10 for the (Senior?).Apart from this abject bit of marketing, these headphones are definitely superior "minis"; very good sound throughout and a bass response that is remarkable - possibly due to the oversized [for a portable phone]diaphragm and the thin foam pads making them sit very close to the ear canal. The efficiency is high too, so a portable cassette or disc player will have no problem in driving them to sufficiently loud levels.
