I bought these headphones to use with my ICOM 7300. I haven't used the microphone yet but do use the headphones everyday. For the price I don't think you can find a better pair of headphones for the ICOM 7300. Sure you can buy a heil setup for a few hundred dollars but these are the best I think you can buy that will work with a newer ICOM radio. They are slightly tight on the head at first but after using them for a while they will loosen up and be more comfortable. The one thing I don't like is the 8' cord but I suppose that is a feature for other people. My radio is about 3 feet from me and I end up untangling the cord often. With an 8-pin adaptor the microphone is useable with newer ICOM radios and has good reviews on eham.

Love these phones for use with my ham radio. Great noise canceling and get many compliments on the audio quality. Can't beat them for the price!

I have an old 1960s set of Koss that I have loved for many years but, I needed to replace them (I do still have and use them). I chose Koss and I'm glad I did. The same fine consistant quality of headphones from years ago. Excellent customer service as well. I would buy Koss again and again. Made In America.

I like headphones. I have a lot of headphones (around a dozen pair). I want a headset that is fairly portable and good for both music and chat. I was looking for a more portable alternative to my Creative Fatality headset, so I was pleasantly surprised to find a set of folding cans with a microphone attached. I've liked my other Koss headphones so far, so I figured I would give these a try. I compared them against three sets of cans and the basic summary is this: every other pair of headphones I tested these against is more enjoyable to listen to than these. Another review said it pretty succinctly and I will paraphrase, listening to these headphones makes you feel like you are in a very small room. But, in addition to being in a small room, it can sound a lot like the music is muffled somehow. During one song in my test I would have gone so far as to say it sounded as though I was in a small room listening to music that was being played in a long tunnel. The worst of this is when I had cross-feed turned on. Most of the time it does not make for a very engaging listening experience. I still can't quite grasp how a set of headphones can simultaneously sound claustrophobic and distant. In fairness, there are some songs and types of music where the very 'in your face' presentation of these headphones makes them sound more engaging than more refined headphones, but I can't really recommend these overall. Finally, they tend to break down in sound quality when the music gets full. They have a very small sound-stage, but like most headphones, playing them louder tends to widen it a little. These headphones get noticeably better when you turn up the volume a little more, it helps enlarge that little room. In addition, despite having all the flaws of a set of closed headphones, they offer very little noise attenuation. I was hoping these would be fairly good at blocking out all the noise of airports and airplanes, but they do very little in that regard. In terms of tonal quality, these headphones are reasonably accurate. No major flaws come to mind. The upper bass (the attack of a bass drum) is rather weak, but lower bass is quite good. High end isn't incredibly impressive, but it's not terrible. The real problem is the acoustics (as described above). Here are the individual comparisons (all tests use my Sansa e280 as the source): Sennheiser HD201 The first test was the most extensive, because after that it was just more of the same. HD201s are cheap headphones, so I thought this would be the fairest test for the SB45. Here are my observations on several songs. Sheryl Crow - Leaving Las Vegas: SB-45 sound very enclosed, slightly bass heavy. Her voice doesn't sound very real. HD201 are physically less heavy. Much more open sound. Its much harder to pinpoint the drivers. Much more open (maybe even slightly thin) through the mid-range. Sheryl crow sounds clearer, but still not really real. Less satisfying bass thump. Schumann's Larghetto from Symphony No 1: The SB-45 manage to simultaneously make you feel farther from the performance but closer to the speaker. It almost sounds like you are listening in an overly cramped room or even through a tunnel. Fiocco's Allegro in G Maj: You start to forget about the compressed soundstage after listening to the SB-45s for a while. But there's a bit of artifact or echo following the violin, it just doesn't sound quite right. Once again, the HD201s bring much more clarity and open sound through the middle. Much easier to forget the earphones and enjoy the music. Beastie Boys - Sure Shot, Tough Guy, and Bboys Making with the Freak Freak: Turned off cross-feed. Closes down the soundstage and dynamics a little on HD201s. Bass response is still quite full. With cross-feed off, the SB-45s stopped having the odd tunnel sound, now they just sound like they're playing in the back of my head. Its actually better. This is the first pair of headphones I've owned that clearly sounded better with cross-feed off. On Tough Guy the SB-45s just sound muddled, but in comparison the HS201s sometimes sound a little less engaged in the music. SB45's feeling of being in a small room works pretty nicely on Bboys Making with the Freak Freak. Born Jamericans - Warning Sign: The SB45s produced less bass than I expected on this track. Voices sounded fine. I'm starting to feel like both headphones are like being in a room--don't forget, the HD201s are also cheap headphones--its just a question of the size of the room. Usually a large room is better than a small one. There's a big difference in the prominence of upper bass as well. I also compared these to my Sennheiser HD280s, which just isn't fair. These things sound awful in comparison. The HD280s are the best cans I own. Finally, I put them up against the Creative Fatalities that I was hoping to replace and the general feeling was pretty much the same as with the HD201s. I also used them for a fair bit of voice chat and found them to be quite acceptable in that regard. If you're hoping to listen to a lot of music I would recommend that you keep looking. If I had to choose between these and the Creatives, I would pay double the price for the Creatives, it is worth it.

The Koss SB/45 headset arrived in packaging tough enough to turn knives and perhaps even bullets. I recommend wire cutters at the edges to defeat it. The headset inside seems as tough as the packaging. the large, padded headband is adjustable and big enough to fit over skulls even as large as mine. It's 1¼" wide at the top of the band and tapers to no less than an inch at the sides. The earpieces are likewise padded and soundly constructed, fitting around the ears, muting but not completely cutting off outside sound. The boom can be rotated vertically from the position shown in the Amazon photo to a completely upright position. Oddly enough, the microphone boom is springy rather than bendable, so you can't position it horizontally closer to your mouth. This may actually be an advantage as people often position the mike too close, and the flexible boom may be more likely to survive dropping it on the floor. I've had no complaints from people I've called on Skype, nor has anyone had trouble hearing it in MMO games. My hearing isn't what it used to be but it sounds fine to me. The connection to the computer is the old-style twin 3.5mm headset and microphone plugs, which I prefer to USB headsets because they work off the existing sound hardware in the computer rather than introducing a new sound device. Switching between headset and speakers only requires unplugging the headphone jack rather than changing default sound devices in games or the operating system, and you save the USB port. The eight-foot wire gives you enough reach for most desktop computer arrangements. This wire is unadorned by any mute or volume control. Some have expressed doubt that the wire is thick enough to stand long abuse, but it's thicker than most wires I've seen on other similarly priced headsets. While the earpieces can be folded in and the microphone boom rotated to make it more compact, I think most people would find this headset unsuitable for use with laptops and smaller devices while traveling. Koss stands behind this headset with a limited lifetime warranty that basically states that they will replace a defective one (with one of equal value if the SB/45 is no longer available) for cost of returning it to them with a $6 US check, as long as you're the original purchaser and no one else uses it.
