Arrived on time , one word awesome !

From now on, I'm a rebel with a Koss. I bought these because I hate the clunky modern headset style that bled out from gaming headsets onto everything else. These were cheap and, I'll be honest, I heard the brand name on Mad Men so I figured Koss is a good brand to be in business for so long. I love how light they are and I was left baffled by the frequency on the headphones. Most new headsets tend to have muddy and boosted bass which I find to be disingenuous but the Koss headset has good balance: the highs won't hurt your ears while the lows are very satisfying giving a clean and punchy bass. I haven't tried the microphone myself but I've read lots of reviews mentioning similar excellence in regards to the microphone's dynamic range. Overall for the price I'll be hard pressed to buy ANY OTHER headset for the foreseeable future. I'm in fact tempted to buy these in bulk and stock them for use in the rest of my earthly life. I never want to use another headset.

Pour dépanner le son est insatisfaisant et le micro sature facilement le bras en plastique est de plus plutôt fragile

Got it for online school. It is good for the price. At first, they were tight and hurting my ears but in time they loosened up. Now they are a bit loose but still ok and stay on my ears. I do like this headset because if the padding on the ears. The mic is good, it is just what I wanted but it is not the best that you can get. If you have a low budget this will do .

Great product. Works well. Excellent mix. Ears get a bit sore after many hours of use but that is to be expected.

I bought my first Koss Communications USB Headset with Microphone (CS100-USB) out of desperation. I have a lovely computer my brother bought for me when my previous one went down a few years back. The only problem with that computer is that it came with a terrible sound system, and no way to expand it. It's a work-based computer, but due to its high processing power and good array of RAM, it works great as a medium-grade gaming computer.In order to utilize it the way I need to, I had to come up with a way to make the USB system provide decent sound from both my system and my voice, in order to record videos for my Grandma's Gone Gaming YouTube channel.I tried half a dozen or so USB headsets, that didn't adequately provide much of anything, PLUS they added an overlay of electronics noise, through the USB connection...VERY aggravating. Another problem with many of the other headsets I tried, is that they were very heavy and tight, therefore troublesome to me in several ways, physically.So I started trying the lightweight ones. Each one had pros and cons, but then I landed on this one. It has a good noise cancellation system that works. It's not perfect, but it's way better than some of the others I tried. As long as I adjust the mic correctly before I begin recording, I have no problems with that part of the equation.The quality of the recorded sound is EXCELLENT. I get no feedback, except for an occasional hum or breath-burst if I have bumped the mic somehow, getting it too close to my mouth. A simple adjustment takes care of that. Many people have commented that my sound has been recorded quite clearly and crisply, which pleases me.The set doesn't have a built-in on/off and volume control fixture. All volume control is accomplished through the system's built-in control, and it works seamlessly. If I want to record more loudly or softly, I adjust the volume on my computer...done.The headset is snug enough to be firmly placed on my head, but not tight and restrictive to either my head or ears. I can wear it for long periods of time, without discomfort. The earpads are ON-ear, not OVER-the-ear, so they don't stop ALL the noise around from filtering in, which is fine, because I like to include some interaction with others in the room at times, plus I NEED to be aware of what's happening around me.On the other hand, the pads fit snugly enough on my ears to keep out most of any sharp or invasive sounds, and for other voices to be recorded enough to be easily heard by my watchers/listeners, the others in the room have to be standing right next to me, and speaking fairly clearly. It all "works for me."There are only two things I'd love to see improved for this headset:(1) The adjustment sliders above the headphones, to which the head brace is attached, aren't well-designed. In order to keep the adjusters moved out at about 3/8" on both sides, I've learned to resort to a small piece of clear packing tape on either side, because otherwise I'm always having to re-adjust the sliders, which gets annoying really quickly. Since I've used these headsets for quite some time, now, it's just something I do immediately, upon receiving a new set.(2) As wonderful as the sound quality and ease of use has been, the headset isn't the most durable set I've ever seen or used. It's not the most fragile, either, but it has a definite effective usage time for me, that seems to be about six months. Then the earpad swivels begin to wear out, and the earpads themselves get worn to the point that they aren't as soft and cushiony as they were in the beginning, and they begin to irritate my ears.Since this headset is quite inexpensive, that's not been a huge problem. I pass on the headsets to my seven grandkids (out of our almost 22) who live here with us, with their mom (our youngest daughter) and dad. Everyone, then, gets to benefit from the headsets, over time. Then, when (after a year or so), the additional (hard) use has broken some other parts of the sets, they are thrown away, just in time for a newer pair to be passed down.Again...it works for me. :-D

Its microphone grabs the attention of my listeners with clear and crisp sound...

I ordered this headset to use with my Dragon Naturally Speaking speech recognition program. I also use it with another speech recognition program that I use online.I've been using it for a good while now off and on. This headset makes it easy for me to complete my writing projects quickly because I can dictate the information verbally instead of typing it.PROS: You can dictate many writing projects. For example,you can dictate your post for your blogs and websites, for your social media sites, and you can dictate articles if you are so inclined.The headset is lightweight but sturdy, and it is easy to use. It is adjustable so it will fit any size head from large to small.The microphone is adjustable. It bends inward or outward so you can easily get it in just the right position from your mouth.The sound quality is good. I only use it for dictating my writing and for listening to music. I find the sound quality to be perfect for me, although I am NOT a professional of any kind.My daughter, a communications specialist on her job, has used my headset. She routinely records videos for presentations as part of her job. She reports that the sound quality is very good. She was impressed that I had such a nice set of headphones.The extra long cord is a plus, in my opinion. The long cord makes it easy to move about the room as you dictate your work. You are not locked into one position where you have to sit still and stay put.CONS: The earpieces do not cover your ears completely, so they are not as "noise-blocking" as my daughter finds necessary while recording videos.Also, the two plugs are confusing for those like me who are not tech-savvy. The plugs are called Dual mini-jacks. One of them is for sound and the other one is for the microphone. It took quite a bit of experimenting on my part to find out which plug goes where.In my opinion, this headset is worth the price. It is a good buy for the money if you are not looking for professional studio quality equipment.Personally, I recommend this headphone set because it is sturdy, it is adjustable, it delivers good sound, and it is great for writing using speech recognition programs.

super headset, sitzt weich und gut auf den ohren, drückt nicht auf den ohren nach mehreren stunden, der klang ist gut, nur das microphon ist etwas lang, und durch das atmen springt es im ts immer an, aber einfach das mic einknicken nach hinten und es hat den perfekten abstand seitlich zum mund und man atmet nicht ins mic hinein! und vom preis her nicht zu schlagen für den komfort!
