Growing on me  Time owned: 0 to 3 months
Have started to grow on me. Seemed a bit bright on receive, at first. I learned to turn the volume down to almost silent, where just the voices pop through. Mic is a bit lacking in bass, but very clear. Happy, for the cost. Radiosport sells ear cup socks that also fit these koss headphones, and will extend ear pad life. Would give a 4.5, if I could.

Not so impressive as I thought they would be  Time owned: 0 to 3 months
Kind of disappointed in these, mainly on receive. The mic sounds nice, but the receive accentuates the already sharp/noisy highs of my Icom 7300 too much. I get more hiss, and less midrange. I can't say I'm impressed, overall. For now, I'll be going back to the cheap Sony's I've been wearing. Sadly, they don't have a boom mic on them.

I want to add that the Koss headset is made of the same cheap earpad material that my Sony's are (this is my 2nd pair of Sony's). That cheap fake leather material is like thin paper, and after about 2 years, will begin to flake off and stick to your face. I was disappointed in seeing they come with that, also.

Very Under-rated  Time owned: 0 to 3 months
I'm fortunate in that money is not a real issue for me. I buy what I want and never worry about the price. I have extremely good hearing, but that makes me need to use NR/NB on my radio. That makes it a bit more difficult to hear the QSO. I was at a friend's house and we were playing some computer games. His wife was complaining to turn down the sound. So my friend let me try his SB-40. I couldn't believe how great the audio was. Especially for a $25 pair of headphones. I researched it for my rig, but I wanted to use it for my ICOM. So the Sb-40 wasn't good because of the dynamic mic. I needed an electret mic. I checked out the SB-45 which has the same headphones, just the mic is basically the only difference. I couldn't be happier. I don't use it on my Yaesu rigs because of the microphone, plus I have some excellent studio mics I use for the yaesu. But for the money; the SB-45 ($25 on amazon) performs as well, or if not better, than my $300 Rode mics. (At least according to QSO contacts). And the speakers in the SB-45, for my hearing and comfort, sound just as good as my Shure and AKG that I use for my Yaesu as well as I use to in my recording studio. There is no doubt, if you have an ICOM radio, and are looking for a headset, definitely buy the SB-45. For $25 you can't go wrong. Obviously you'll need an adapter for the 8 pin icom. You can buy one from from Heil (AD-1-IC) for about $25, or on ebay from K6VHF for $19.99 (Free S/H). Either way; this is a kick-a$$ mic/headset for the ICOM radio.

Good headset  Time owned: 0 to 3 months
Adequate headset. Only nits are cord from headset to radio is very thin and likely to break strands when stressed (not robust). Boom mic flops about, not rigid say like a Heil headset. For the price though, should prove a good unit to have around. If it were a bit "beefier", I would rate it a 5.0.

Can't be beat  Time owned: 0 to 3 months
High sensitivity on the headphones means that the volume can be turned down overall. Great adjustable headband too. I have owned many Koss headphones through the years and have been happy with all of them. Highly recommended.

GOOD BARGAIN HEADSET  Time owned: more than 12 months
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. You may want to employ an simple attenuator pad, such as is described on Page 64 of the November 2013 QST magazine, which attenuates mic output signal strength to approximate that of a typical performance style dynamic microphone. ICOM and Elecraft users will like it just as it comes as those rigs are designed to use electret condenser capsules.

I contend the SB-45 headset is every bit as good as the popular Yamaha CM-500. Both of these headsets have been used by a successful contest team I sometimes work with, and our operators consider them completely interchangeable.

Good value, solid performance, comfortable over long sessions. Cannot go wrong unless you demand a fancy, expensive broadcast quality headset.

Just My take.... / K8JHR /

Great value for the money  Time owned: 0 to 3 months
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. The mic is far more sensitive than the Yaesu MD-1 that I also have teamed up with the FTdx-1200. So far, I'm impressed. You can't ask much more than that.

good set of headphones  Time owned: more than 12 months
Big difference between these headphones and the Heil traveler dual. I'm using the Koss headset for the 10m contest, using the Kenwood 480 with CW filters and with the Heil I had the sound between 12 and 1, switched to the Koss and dropped it down to 9 and I was able to hear stations that I couldn't with the Heil. On voice I get reports of a hum on my audio with the Heil but when I switch to the stock hand mic it goes away.

Good  Time owned: 0 to 3 months
I bought this for my HF rig. The Microphone is a ELECTRET and needs a supply voltage for operation.
It works great with my 746pro Xcvr.
The reason for Good instead of Great is that the headphones squeeze my head. I will see if there is an adjustment [bending ?].
I get great audio reports using the TX EQ suggested by Heil.
