    • I received my Koss headphones w/mic a few days ago and they are working good as expected.
Size: apple Style: SB45-USB Pattern: Headphone
I bought my Koss headphones w/mic for the purpose of not disturbing the rest of the house while I listen to music from my PC (sometimes I crank up the volume). They are working as expected, and they are very light (primarily made of plastic), but I have not tried out the microphone yet. I hope the clarity is good from the microphone. The headphones sound very good to me. I'll say the sound is average but what can you expect from a set of plastic headphones that cost around $35. The soft leather that wraps around what ever is spongy inside the ear cups and head band are superb. I have trouble hearing some high notes, but the low and medium notes come in nice and clear, and the bass notes sound great when the music has them. They are not sound cancelling for noises such as voices, though when I play my music with them my girl friend does not hear the music at all while sitting next to me. It is money well spent, even if the sound is "average". Though the fit is fairly good, it took awhile to get comfortable with them, I had to re position the headphones around my ears. I don't have large ears, but the comfy ear cushions are snug enough. Once positioned nicely they could be worn for hours. I will say that after one or two hours my ears were beginning to sweat and itch. But that is just me, the ear cups are vented at the top. When using the headphones and not needing the mic, I swing the mic upwards in line with the head band were it is out of the way. The microphone needs to have a little bit more tension on the swing arm because while adjusting the ear cups to properly fit my head the mic drops down one or two clicks, either front or back. I hope this helps someone making a tough decision to buy these or another brand. ... show more

    • Excellent Headphones for the money. Microphone exceptionally good with voice recognition.
Size: apple Style: SB45-USB Pattern: Headphone
If the price were higher it would have been four star, but for the money, these headphones w microphone are excellent. I am very surprised with the quality of sound and accuracy of the mic. I bought them primarily for a computer based class with voice recognition and can report the mic is right on - far more accurate than the set that came with the course and an older set I had that cost twice as much. I've been listening now to music with them and find the sound very good. Nice sounds at all ranges from fairly low bases to higher notes. They are also very comfortable and the headband can be easily adjusted and I would think they would fit any size head. I really like the padding around the ear pieces - they fit snugly and very comfortably and eliminate all ambient sounds from the room so I just hear the voices or music I'm listening to. They worked perfectly the first time I plugged them into the USB port - I have a Win7 desktop. And since they are USB you can plug and unplug them numerous times, which I do, with no reloading of software. Koss really came through on this product! ... show more

    • Great sound, but a few quirks with comfort and design
Size: apple Style: SB45-USB Pattern: Headphone
Great sound, but a few quirks with comfort and design The Koss SB45 USB headset has been a solid performer in terms of sound quality. The audio is clean and clear, and for both music and voice it delivers a surprisingly rich experience for its price point. The included microphone works well enough for calls and online meetings, picking up speech without much distortion. The USB connection is convenient—plug and play without needing any extra setup or drivers. That said, there are a couple of things to keep in mind. The headset feels a little bulky, and the clamping pressure can become uncomfortable after longer use. The plastic build is sturdy but not premium, and the red color is bold—some will like it, others may find it a bit flashy. The ear cups also don’t breathe much, so in warm rooms you may feel heat build-up after extended sessions. Bottom line: If you’re looking for a budget-friendly USB headset with strong audio and decent mic performance, this is a solid pick. Just be aware that comfort over long periods may be an issue, and the design is on the bulkier side. ... show more

    • Fixed Skype
Size: apple Style: SB45-USB Pattern: Headphone
Sorta big. Microphone wire is sort of STIFF and stays where it wants to, a bit hard to shape it to where you want and it doesn't move after that. That said, I was having many issues with my laptop microphone and the internet speed provided in my basic package. (I was not going to pay $1100 for two years of 'enhanced speed' "under contract" to try to fix it). The sound quality is excellent, the microphone does pick up very well, and with the USB plug if I had a wonky audio plug that issue is now moot. I have tinntinitus so an objective on range of the ear speakers isn't really possible. I will say I can easily adjust this on my sound controls to seem balanced to my hearing; I can hear friends speak to me very well; and they can hear me plainly and clearly now. Skype calls are now back to being possible, clear on both sides and standable. Even in group calls. I will recommend these if you need to do or make a lot of Skype calls and are having problems. Earcups seem comfortable as well, and there is a bit of cord length. I can get up and grab something off a bookcase, not really move from the area of my computer chair, but, not tightly leashed either. I give it five stars because these seem to be an excellent solution to what looked like an expensive problem. (and taking my laptop apart to put a new audio card or set of audio plugs in it, plus replacing the cam/mike, wasn't exactly what I wanted to do either) ... show more

    • Koss sb45 usb headphones
Size: apple Style: SB45-USB Pattern: Headphone
I rate this product very low because they have not worked correctly from the time I took them out of the box. I bought these as a christmas present for my wife and we both were very disappointed in the quality. There is a loose wire in one side of the headphones and when you listen to music one side will cut in and out. I like the style and comfort of the product but not the sound quality. I have had Koss headphones in past years and I liked the sound quality, that is why I chose this product in the first place. If they worked correctly and the sound quality was up to par I would be very happy with them. I want them replaced. Do I work with you people or do I have to go directly to Koss? This experience makes me wonder if I will ever order from you again. Please respond. Thanks,Mike ... show more

    • Gets the job done
Size: apple Style: SB45-USB Pattern: Headphone
I decided to try Koss again after using some Radioshack-branded Koss headphones a few years ago. Not much has changed since then, even though headphones have advanced significantly since then. Pros: Decent performance for the price. Headphones fold over making it easier to travel with considering their size. USB interface makes for consistent digital microphone performance compared to analog. Decent cable length. Cons: Huge USB plug. I'm assuming the USB circuitry is immediately attached to the port before going into the headphones. This is probably more a problem for laptops than desktops. Headband is not adjustable to fit to my head. I sometimes wear the headband closer to my forehead to make more room. Decent bass performance for it's size, but nothing notable. Huge ear cups done get any ventilation. May need to remove headset periodically to get some ventilation going. No inline mute button. You'll need to mute from within the application. Overall, there might be some more impressive headsets and far more expensive headsets, but I didn't want spend hundreds of dollars to find out and only get mediocre performance, so ended up here. ... show more

    • Purchased January 28, 2016. As of today, the right side speaker has stopped functioning.
Size: apple Style: SB45-USB Pattern: Headphone
I use these every day at work. I take them on and off multiple times during the day. The joints are flexible and malleable. With some minor adjustments, I was able to find a good position to wear it on my head, but the foam pads are a little too shallow, allowing the tops of my ears to come in contact with the plastic interior of the ear cup, which causes a little ear pain necessitating that I adjust positioning every once in a while. As of today, the right side speaker has started to go out, depending on the position of the left side speaker. I can adjust to an extent and it will start working, but this heralds the end of this headset's era. From what I was able to perceive, the microphone seemed to work well. I never received any sound quality complaints when using it to make phone calls. I was hoping to get more time out of this headset. I think it was a mistake for the manufacturer to use what appears to be 20 gauge wire to go between the left and right side speaker. Further, the USB cable seems like it's supremely fragile. I honestly had expected the whole headset to go out first due to the number of times I'd run it over with my desk chair's wheels. C'est la vie. The whole time I'd used this, I have been running Ubuntu, which fully supports this headset. ... show more
