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

You get what you pay for


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)

Good Headset only one complaint


The headset is very good, would have made it 5 stars, but the time it took from date of order to the headsets being shipped. Not sure if this is a Walmart thing, or Koss shipping thing. The order sat in processing for close to two weeks, almost...

works great!


It's not as silver as it looks in the picture. Has more of a goldish tint to it. It works great. It's clear to listen through and others hear me clearly through the mic. I recommend!
