Great Headphones.... 
2008-10-01
I have had my Koss SB-45's now for about a month. I use them for college online classes. These are very comfortable, the over the head bar is well cushioned, the over the ear style blocks out a lot of the background noise. NOT all of it, mind you but, they are not noise canceling headphones. The boom mic swings out of the way when not needed and works well. For what I used them for the sound quality is excellent. Two thumbs up in my book. I also bought the inline volume control and the cushioned carrying case, both work as stated and made mice additions to my set up.
Great for Online Gaming 2008-09-13
I play many online games and use voice programs like Skype and Ventrillo. I also have my entire music collection digitized on my computer and often use my headphones to listen to my music using Windows Media Player. I had been using flimsy Logitech headsets for years and had gotten used to duct taping them together when the cheap plastic broke and putting up with the discomfort that came from wearing them for extended periods of time. I finally got fed up and tried Koss on a friend's recommendation and have been extremely happy with this headset. This headset has great audio and is extremely comfortable even after wearing them for periods greater than an hour. The are well constructed and extremely easy to use. I highly recommend these for gamers, audiophiles or simply someone who wants a good prodcut at a fair price.
Economical, Sturdy,Light, Very Comfortable 2008-09-03
First let me say I prefer headsets that enclose my ear completely.I am using these headphones for online gaming and chatting and find them to be an excellent value. The sound quality is very good , mic has great noise canceling and is crystal clear on Ventrilo. I would not use them to listen to stereo music but for online gaming they are perfect.
I have tried many headsets and most of them didn't make the comfort grade. I find these phones to be extremely comfortable for an enclosed ear headphone. I can wear them for a long time without any discomfort whatsoever. To the negative reviewer about they are too tight on his head I found that most headsets were too tight on my head but these are not.
The are very sturdy. I really like the mic arm which is hinged (as opposed to the bending type)and clicks into position and be moved away when not in use.
I can honestly say this headset is the best I have ever used. Congrats Koss !!
Best headset/microphone I have ever bought. Very clear sound, excellent for music listenning on your computer, mic is very clear 2008-08-31
Excellent headset/mic. Headset is very good for listenning to music on your computer. The mic is very clear for using in voice chat, and is loud. You have to adjust your mic volume on you computer, but this mic is great....
Great Headset 2008-07-22
Everything about the SB45 is pretty much amazing, the only trouble is sometimes the mic pick-up but it works.

Goog but tight on the ears

The sound on these is great but they hurt my ears as they are too tight on the head.
Koss...Still Going Strong after 50 Years! 2008-05-17
I bought my first pair of Koss Stereo Headphones almost 50 years ago (in 1959). I had just built a DynaKit Stereo System and I wanted a good set of stereo headphones to match it (stereo was quite a novelty in the late fifties). Koss headphones were rated highly even then and although I don't remember the model or price, I'm sure they were fairly expensive. Those headphones lasted me about 30 years until they finally gave up the ghost from a lot of use. Just recently I decided to buy a new pair of headphones for computer telephony and started to look through the large selection at Amazon. The Koss SB-45 phones caught my eye and in a fit of nostalgia, I ordered them. Since they were slightly over $25.00 I took advantage of Amazon's free shipping. They're just what I wanted. Nice and solid with excellent sound and microphonic qualities. I couldn't be happier with my purchase and I'm really glad to see Koss is still alive and well in the good ole USA. I highly recommend these inexpensive, quality headphone (with mic) to everyone.
Incredible price for incredible sound! 2008-04-28
I wanted a good gaming headset. Looked around, and this was recommended. Boy, am I glad I followed that advice.
I've dinked around with lots of headsets. Most expensive I tried was the Razer Barracuda headset, and while those got plenty loud (almost went deaf once when I turned off mute), the quality just wasn't there.
These are like 30% of the price I paid on those, and the sound quality is AMAZING. Great range, great volume, etc. The SB-45 is dirt cheap for what you're getting. And they're comfortable, too.
Gaming... music... everything is wonderful. I'd use these as regular music headphones with my MP3 player, too, but I'd feel weird wearing a big headset like this, plus a microphone.
Good value--two connectors! 
2008-04-05
The title might seem strange, but the hardest things to nail down about these headphones is whether there are two connectors--one of the mic and another for the earphones. Even the the Koss site suggests there is but one. As the picture I've posted testifies, yes, there are two!
Otherwise, I agree with the other reviewers. Good value. Lots (too much?) bass. I find the treble end a bit weak, but sound is always subjective. Large comfortable. The mic boom is on the left side. The headset can be reversed to put the mic on the right (the swivel allows it) but it would reverse right and left when listening in stereo. I wish the mic boom swiveled down just a bit lower, but the headphones can be tilted a bit to achieve the same effect.
If I did not need a microphone, these would not be my headphones of choice solely for listening. I'd spend a few more dollars for something better. If something were to happen to them, I'd probably try something else (less bulky, better fidelity and spending more money in the process), but I've no real regrets since so many inexpensive products are awful while this headset represents good value.
