I've bought one of these on the basis of your video. I got the SB40, dynamic, as I already had the adapter for my Behringer boom mic. Works really well with plenty of good audio reports. Thanks Tim
I have the Icom 7300 . I can say that theirs DC on the audio lead . Se depending on the head set you may need a cap on audio lead to block the DC. Non polar type. The Heil adapter does have that cap in it . Some headsets need that DC on audio to work. The Icom 9700 is same mic . I have a Heil head set but a different one. The communications one with 1 earpiece and boom mic is the one I have. Works great . I do not use VOX so I have the Heil foot pedal I use. allows me to type with both hands and talk on radio . I did make a hand PTT with a push button switch. I used it once. I just perfear a foot PTT . My audio settings are like you listed. I have had a mixing board on to my 7300 . It is 2 CH . so 1 for mic and 2 for RX speaker. I don't do any video or recordings . just trying things out. The outher good way to get audio report over the air is make contact with someone live streaming like Callum and just log into youtube replay and give a listen. In fact Callum gives a timestamp place so you can find the contact. Cheers from NY !
Great video. I also use the Icom supplied hand mic as well as the Koss SB-45 with my 7300. I have received "great audio" comments while using both. The SB-45 does the job well!
I've had the KOSS SB/45 for x number of years, and many hams told me that I have an excellent audio, and asked me what microphone I use. When I tell them that I use the Koss SB/45, a simple 45$ gaming headset, they are very surprised.
Great video, Tim. I've been using cheap (less than $50USD) PC gamer headsets on my IC-7300 and Yaesu FT-857D from Amazon. I typically get unsolicited good on-air audio reports and guys are surprised when I tell them I'm using a cheap PC gamer electret headset. I built my own interface cables for the Icom and Yaesu radios which work well. So far, no reports of RF getting into the mic. I like the headsets with memory foam ear pieces. The problem I have with most headsets is the edge of me ear rubs against the speaker housing which can be quite fatiguing after a few hours of operating. Thanks for the video. 73 de N6EF.
Hi Jack, I have FTDx10 and 891 as well and I'm thinking about headset... you thing the Koss SB-40 are ok for our radios...? What is it with the connection to these radios ...? Many tnx for your reply ! Dany OK2BAD
Nice video Tim, I also first fell for a then still Heil Eilite 6 and could not produce decent audio performance in SSB. Whether dynamic or electret. Now I've ended up with a good 50 Euro gaming headset, the Lioncast 55, which works perfectly with the Heil adapter, both the microphone and the headphones. Nice sound and actually always good rapports. I have a relatively low voice "bass lowered by -2 and the treble raised by +2. best regards Jan-Peter - DL3KVT-
Very interesting and surprising you should pick up RF on such a high-end headset. Even if your new headset falls apart, you can afford to replace it another 3 times for the same money! I'm just about to buy an IC 7300, so was particularly interested in your comments. Best 73 .
Interesting video Tim. I use a set of Byerdynamic DT220 headphones and a studio microphone, but been thinking about getting some DT108s with the built in microphone. £150 for professional bit of kit and I find them very comfortable to wear.
Looks good value for money Tim but I think I would wear that model out in no time. ps It is quite hard to make an IC-7300 sound bad, although one or two have succeeded LOL
An electret mic need a bias voltage, which is why one pin on the IC7300 mic socket is at 8V, I had big problems with RF when trying to use a condenser mic with my 7300, tried everything to cure it, so I then tried a dynamic mic, and this was problematic because the radios mic gain would not cope with it. Solution, a small one transistor amplifier and a good old SM58 microphone
Nice video Tim as always. I have a Pro 7 headset and to be honest it is way over priced, heavy but does the job overall. Having done music a lot in the past, and still have a little studio, I was used to spending reasonable cash on headphones - but then I was looking at detecting subtle changes of frequency in music compositions. But with the tiny bandwidth of SSB I think the Pro 7 is perhaps way over the top!? What I would say I do get nice audio reports with hardly any audio processing, so I think the mic does the job. Anyway, keep these videos coming Tim, very enjoyable. Mark, 2E0MSR.
Nice video & review. Just got a 7300 here and have been fiddling with getting it hooked up to all the other junk in the shack. Have an old abused mic that runs to the IC718 and the IC7300. But I'm thinking a headset might be nice once I get all inspired to contest with it. Especially with conditions improving as they are. So your suggestions are very helpful. Spent enough on the radio; figure I'll cheap on the headset ;-) 73 de W8IJN
Hi Tim, Thanks for that review. Luckily my Proset headset does not have any issues on the FT-450. Still need more time on the FT-891 to determine if it does or doesn't have any issues. I checked on the SB-45 and it mentions using a dynamic element. Wouldn't that work on Yaesu radios? Stay safe. 73 WJ3U
Hi Tim, according to the specs the hb45 has an electret mic does this mean it's incompatible with my yaesu ft991a which uses a dynamic mic? Koss also have the sb40 that seems to have a dynamic mic but is a fair bit dearer.
PS - your audio quality is very good on videos - yes a "tiny" bit of echo, but you said the ceiling was quite high. What mic and position are you using to record the video ? Mark, 2E0MSR
Hi Tim, well presented video again. Must be the teacher coming out in you, that makes me sit up straight in my chair when I watch your video hi. Iam still trying to find a headset for my ts480hx, ringing and emailing people and companies all over the planet, no one has any info for me. Couple of things mate, headaches wearing headphones, grow your hair a bit more hi, but probably the main problem is your using ssb not cw hi, cw forever hi.keep up the good work. Ps : 40m and 20m open to uk around 6- 7 am your local time, and how dare I say this now, but worked g4air last night on 40m ssb hi, no headset though hi. Take care mate, enjoy your weekend, 73 zl3xdj.
Any chance we could contact one another so I could ask your advice? Can’t do it by radio unfortunately but if there is some way I can get my details to you I’d appreciate it.
Heil is overrated, mine was and is a disaster. The connection where it plugs into the Yaesu RJ mike jack broke the first time it was used. The cable between the headset and radio must go kluged through first, an 8 pin mike plug and jack and then to the RJ plug on end of cable. The one time it did work it was very uncomfortable. In my opinion high priced and overrated.
Well let's start off with the fact that these are not the same headset as the CM500s. The SB45s have a much smaller ear cup, which is fine if you have smaller ears, but if you're a larger person like me then you might find them uncomfortable. The CM500 ear cups will cover your entire ear, whereas the SB45 sit on top of your ears and press down on them. oh and for God's sakes don't put tape over the microphone element, this is a noise canceling microphone, the element facing away from you is part of the phase noise canceling circuitry It's what measures the ambient noise and is used to phase cancel cancel background noise. It's not as good as an aviation Clark headset but it works well enough and If you put tape over The front sensor then you defeat the noise canceling abilities of the microphone. You would think ham radio operators who are supposed to be technologically literate with regards to communications equipment would understand how a noise canceling microphone works, but to read on E-Ham that hams are telling you to put tape over the microphone just demonstrates an humiliating level of ignorance with radio electronics.. I guess it all boils down to the dumbing down of the amateur radio tests, at one time you had to be able to read schematics and design electronic circuits to get a ham radio ticket, nowadays you just need to memorize a few questions to a test. Oh and by the way good job on the video.
.I have the SB-40 for my Kenwood radio and the SB-45 for my PC. My ears stick out, so are not as streamlined as yours, Tim! Consequently I find that the SB-45 is harder wear for long periods, while the SB-40 is fine. There must be a slight difference between the two headsets, like ear cushion depth, perhaps? 73 Gareth GW4JPC

SB45 is great. Use them with Icom , 2 x Kenwood, Yaesu. All with Tecnofix adapters. I think I have 5 sets now! All with 3.5mm plugs.
Thanks Nick, they are very good value

Yes not all fit well for sure!
Managed to get one for £15 from Amazon warehouse this week. It's a bit lighter than my Heil, so will be great for portable.
Good deal!!
I have SB 40 and it works great with ft891 and ftdx10 abt $50 cdn great videos ve7gde
Glad it works well and thank you!

Interesting Gary, a few say the same thing
Great review i have 2 sets sb45 and I love mine,had all heil sets and got nothing but headache thanks
Thanks Paul, that’s my experience too.

Thanks for that. 👍
You’re welcome!
Thanks Tim, what do you use for PTT with this headset?
Best Wishes
David M7CZM
My question too. Dan N7DKE
Hi David I use a Heil footswitch 73
Thank you for the video. Can you tell me where to get a PTT button for the adaptor please?
It's OK I found it on the Technofix site. Sorry to trouble you Tim.
No worries. 73

Hi Don, my impression is that the sb40 is useable with yaesu radios but I’m prepared to be wrong on that. 73

Hi there - yes for the Yaesu you would need to use the 40 not the 45.
PS - your audio quality is very good on videos - yes a "tiny" bit of echo, but you said the ceiling was quite high. What mic and position are you using to record the video ? Mark, 2E0MSR

Great to hear the bands opening Brian. Appreciate the comments 73
Nice one. The microphone input of the icom ic7300 Impedance: 600 Ω and the Kos SB45 is 100 Ω. Do You use any type of audio transformer?
No just the technofix cable
Any chance we could contact one another so I could ask your advice? Can’t do it by radio unfortunately but if there is some way I can get my details to you I’d appreciate it.
Email me via my QRZ profile
Have you tried the Yamaha CM500
No I haven’t but I believe these koss headsets are very similar
This HS can be bought on Amazon cheaper than Currys if anyone interested
Yep I’m not surprised
Would their be a wiring how to for this headset/mic and the IC-7300 ?
I know the IC-7300 mic pin out but I would like to know the the pin out of the 2 plugs on the SB45
I just use the adapter plug mentioned
Heil is overrated, mine was and is a disaster. The connection where it plugs into the Yaesu RJ mike jack broke the first time it was used. The cable between the headset and radio must go kluged through first, an 8 pin mike plug and jack and then to the RJ plug on end of cable. The one time it did work it was very uncomfortable. In my opinion high priced and overrated.
Sorry you’ve had a bad experience .. not good
If it ain't broke don't fix it!
