BM800 Microphone and Icom SM-50 Comparison – Recorded Audio

I am on either the Icom 7610 or Icom 7300 daily and I spend a lot of time on SSB. A while back I got an Icom SM-50 off of e-Bay for a low price. It does happen occasionally, hi hi. I compared it to my BM800. The BM800 Microphone ($20) really does sound good. You won’t be disappointed. Lots of Hams ask how the BM800 is connected to the Icom radios. I use a Y cable that came off E-Bay (HS-01C), a foot switch and a Samson mic boom.

BM800 Microphone and Cables

BM800 XLR Cable

The BM800 Microphone comes with a XLR to 3.5mm cable.

To connect to my Icom radios I have used this Y Cable I got off of E-bay (HS-01C). It’s in my camper with the 7300 right now.

I use this foot switch. Be sure to get the correct plug for whatever Y cable you are using.

Currently, in the ham shack with the Icom 7610, I am using a Heil AD-1-iC cable. I like this one, but it does require a small stereo female jack to mono plug adapter for the microphone input. Not a big deal.

No need for phantom power. This mic gets power from the Icom radio. I have it on a Samson mic boom.

This microphone works great using VOX.

Icom SM-50

I got this one pretty cheap off of E-bay, but I was prepared to buy it eventually at full price. It’s a nice desktop microphone and well built. It seems bigger in person than in the pictures I’ve seen. I like this sturdy microphone.

The lock comes in handy and I can tell a difference between low and low cut. Listen below.

Audio Recordings of BM800 and Icom SM-50

Curious to know what your TX audio sounds like? Use a online SDR.

These audio recordings were saved from a SDR receiver in Utah. There are many variables, including band conditions. So many mic settings to choose from.

Note: SM-50 can be used with mic bias on or off. I have it on.

BM800 Microphone – Comp 3, Bass -2, Treble +4, TBW, Wide 200-2900 Hz.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I just connected a Heil ICM mic, and was surprised to learn that I now must set mic gain to 10% with comp on, or
18% with comp off. Your BM 800 sounds good.

Hi Rich
For some reason my laptop cannot play your files.
Either unsupported format or wrong path.

BM800 gets my vote, but both sound good to me.

Hi Rich,
For me the BM800 Microphone sounds much better than the SM-50.
However, I am 73 years old and I know that this might not be true under hard conditions.

Hi Rich,

Have you tried either microphone with your Drake TR-7?

Hi Rich,
From my OLD ears, there is not a lot of difference from the BM-800 and the Icom SM-50 set to the “Low” position. However, I prefer the audio from the BM-800, it may have a little wider audio response and a little more presence.
Thanks, Ed KD5EH

Hi Rich,

Hi Rich,

I have the 7300. Call me a ninny, but can you show how you connect the BM800 to the 8 Pin Mic Headset Adapter HS 01 C? The 8 pin has 2 connections and the BM800 (as far as I can see) has one.

I just want to make sure I am getting the right parts for the project.

I’m not to savvy with the microphones.

HI Rich,

Do you think there is any difference in these two mics, although they are the same?

Between the Zingyou and Voilamart, that is.

Thanks for any help.

Just got all of my parts for this exact same setup. We’ll have to catch up soon! Thanks Rich!

Hi Rich,

I just got the HS-01CD adapter along with the BM-800, but the Mic isn’t working.
The PTT works fine.

I received a HS-01CD. Do you think that the HS-01CD is different from the HS-01C?

When I clicked on your link, the CD was the suggested.

The seller is out of town for a couple weeks, so my inquiry will be delayed.

Any suggestions are greatly appreciated.

Hi Rich,

I was afraid of that. For some reason I thought dynamic was the one that would have worked.

I did email the seller, but he is out of town right now, so I will let you know in about three weeks.

If I dared to, can’t I just rewire the one I have?

I guess I don’t understand the difference between the two.

I searched eBay and came up with no matches.

Thank you for all your help.

As I said, I will keep in the loop.

Your recordings are kind of confusing to me, the BM-800 is listed at the top up away from the recordings then the SM-50 are there twice. Makes it kind of hard to determine which is which and then there is 3 recordings and only 2 mics. Would be much better leaving all the settings the same and just make one recording for each mic.

Hi Rich

Having Just listened to the recording, the BM800 does appear a little less in overall Level and a little more Bass response. Maybe this is because the overall output level to my ears sounds fractionally less. I wonder if the Audio scope on the 7610 showed the same level on each Mic. ?
I’m awaiting delivery of my SM-50 so I’m quite looking forward to testing it.
I always like the sound of Boom microphones but the extra hassle of leads everywhere and footswitches puts me off it’s not like we don’t have enough wires in the shack as it is. So for me the quality and simple solution of a Desk Mic suits me great ( I Hope ) lol

Thank you for this review. I was considering both microphones, but I have to say having more calbes/etc to make the BM800 ‘work’ put me off. The audio quality of your recordings sounds about the same.
That and the positive reviews on eHam i went with the SM-50, it looks a quality bit of kit.
Thanks again, and hope to catch you on the air sometime.
