Excerpt: I have tried and own more than one brand of headset for my ham radio setup including the popular brand Y which also are very good, but I find the Koss SB-45 to be as good or better for almost half the price. Plus I like the noise cancelling aspect and they seem to me to be more comfortable and light in weight. I have three pair.
Summary: Owned these for probably 3 years. They're still going strong and can't be beaten for their price point.
Pros: -Comfortable for long periods of time -Cord doesn't tangle (Every headset I've owned prior to these have had this problem. It's refreshing that these don't have that issue, especially at their price point -Good audio and microphone quality
Cons: Only a slight annoyance is the mic is a little wobbly when in the upright position and tends to move around. Along with this, the quality of the microphone can be spotty if in the wrong position. But moving it slightly has always remedied the problem.
Summary: The sound is great and the mic come through clear, however the ear peices were not made for extended use and i would not suggest buying this if you plan on wearing it for more then an hour or two.
Summary: i bought these site too store, an i was notified by email 3 days sooner then the expected date they said it was going to be at the store. i have only used the headset a couple of times, it was used for training sessions i do online. the sound of the persons voice i was talking too was very clear and easy too understand, and my hearing is not the best. i asked the person i was talking too, if he could hear me clearly, and he said, i sounded very clear, no problems.
Summary: The KOSS SB-45 is a real bargain. The SB-45 sounds good and is comfortable to wear over extended operating periods. Microphone audio is good enough. While dropping or tossing this headset around the shack is contraindicated, this headset is well made and durable. What do you expect from a $40 headset? The electret condenser type microphone capsule is rather "hot" and presents a strong signal to the rig.
Summary: Purchased these to replace a popular gaming brand name set. The first set broke and was replaced via warranty, second set broke within months, warranty no good for 2nd set. Got these Koss because lifetime warranty, they seem better built and actually sound way better, mic works way better too. All this and half the cost of original set. Its the way to go, I've always been a fan of Koss.
Summary: The headset is comfortable, it doesn't feel heavy, and the cups don't press against my ears. The cups are adjustable up and down, and the microphone boom swivels up out of the way. I wish it would go another notch lower, but it seems to be all right in the lowest position. The headphones fold up flat so they're easier to stow in a suitcase or drawer. I didn't have a bit of trouble using this headset.
Summary: I've only had this set for about a week, but the field testing has turned out quite satisfactory. Mind you, this is a very inexpensive headset combo, but it works very well and feels very comfortable. I have worked several hams and their comments to a man were "don't change anything". Good crisp full range audio in the mic, and the phones reproduce the incoming audio as well as any I have previously used.
