KOSS SB45 Circumaural Headset: Amazing Quality for a Low Price


If you've ever intensely shopped for the perfect headset you know how frustrating it can be. Read about my personal experience headset shopping and the excellent product I found for a super low price.

100 ohm


This is a 100 ohm headset. You need more than onboard motherboard sound to push these headphones. If you don't have a dedicated soundcard with a headphone amp, they'll sound thin and weak. Although, if you've got the power to push them, they sound...

Awesome for the price

Mic is average at best

Does the job


Worked right on plug-in. Sound is about what I expected for the price. Not the best headset I have owned but it will do the job. 8' cord is great

Does not sync to aftermarket Dolby Digital USB

Great sound


Great headphones for the money.

Fit is great. Sound is great for music and telephone. Excellent bass response

I wish it had an inline volume control, but I knew that it did not going in so really can't complain

works great ; cheap ; feels good

when trying to put them on my head the socket that holds the earphone to the headband broke and the other side went only a week after. I had it for a couple months before this happened

Died after two months


Was a solid headset while it worked, good mic and audio quality

None originally, apart from discomfort after prolonged use. Two months after buying however the mic died. Was working fine, unpligged the mic and plugged it back in again 10 minutes later and it didn't work

Worked for a while


They were a nice price and after reading many reviews I decided to get these over a pair of (another brand) which were fifteen dollars more. They worked very well for games, and ventrilo sounded crisp and clear. Others on vent said I came in clear as...

I'm not rough with these at all. The wire at the point it leads into the headphones has shorted out. Sounds are still clear unless the wire gets touched or wiggled. This happened about 3 days ago ; Also, after not being on ventrilo or skype for about 1...

Working since 5/16/2009


I've had several headphones die on me due to my gaming amount, but I've had these for 3 years now with no decrease in performance. Highly recommend

Great headset


The muffs on the ears do make your ears get a bit warm; but really that's typical from any headset with a similar design, and should expect that.

Fantastic headset, great audio quality, mic works well--able to use it on either the left or right side of your head, it swivels all the way around so it can work either way, whichever you're more comfortable with. One thing that should be noted,...

Good headphones, bad wire


They still work, and I will probably just cover the wires with tape or something for now, but I am still disappointed to have to do so this early on. 3 eggs because of the wire. Would have been 5 other than that.

Good quality sound. Maybe it's just because my last pair was pretty beat up and dying, but these are noticeably better ; Comfortable. I am both a transcriptionist and a gamer, and sometimes wear headphones for 8-12 hours a day. They have yet to give me...

The wire was damaged in less than a week, it's as though someone took three copper threads and spray-painted them black. I've gotten it caught on my shoe and scraped it a couple times by accident, but all my previous headphones took far more abuse and...
