Recommended by fellow gamer ; So far so good

No clip or inline volume / mute control but those are MINOR details as long as headset works good ; Sort of tight on my BIG FAT head

Koss CS100Supra-aural Communication Stereoheadphones


A comparable Logitech would of been a better choice IMHO

Shipped fast, they work

sound is poor, an on/off switch somewhere along the cable would have definitely raised the rating another egg or two

Solid product


Suund quality seems pretty good to me for music, but I am by no means an expert on speakers.

Excellent voice recording for programs such as Skype. I use this headset to talk to my folks with Skype and it works great. I also use it with BF2 VOIP--works excellent as well

Kind of hurts your ears after wearing them for extended periods of time

I was looking for a set of comfortable gaming headphones, and I got them with the Koss SB45. They were on the higher end of the spectrum when it came to cost, but the build and quality of the 'set makes it worthwhile. The sound quality is good...

comfortable ; good sound quality ; decent background noise filtering

long-ish cord (I rewrapped it with a twisty-tie)

I have been using this model for years. When one breaks I get another one. They do last a long time if you avoid stepping on them, vacuming the cord... Best sound quality for your buck.

Koss CS100 Communication Stereo Headset


I had found a review of headsets somewhere on the net that said this pair was a best value for the price. I went with it based on that and found it to be true. My voice over internet calls are much better now than with the more expensive pair I used...

I, like the previous reviewer, bought this based on a review I saw on the net, comparing headsets (probably the same review?). This was one of the best buys in that review. Although I have not used it often in the seven months since I bought it in...
