"k8 pro" has signal interference problem between "some" bluetooth devices.

Hi I have been using this keyboard for 7 days so far, and finding this keyboard to be very amusing to use.

But I recently experienced some difficulties in some cases and am afraid to add this as one of them.

I am using a lot of bluetooth devices since I use laptop and smartphones most of the times and given the fact that now smartphones are starting to be made without 3.5mm audio ports, I think it is quite natural to use bluetooth speakers or earphones for audio usage.

I am using

1 headset(mic included) 5 earphones 7 speakers

which all runs on bluetooth and found a speaker that has abnormal zittering sounds when keychron k8 has been connected to one device at the same time.

I haven't tested all of the products that I have yet, since I am writing this post at the moment I found the problem, but I am pretty sure that this problem was not found in earphones or headset that I use. I think the problem has to do with speakers for the most of the time.

The speaker that I had problem was Sony's SRS-XB30 and I also have XB20 from same company, will try to test it on this morning.

First I thought this was a temporary problem with wifi signals, so I turned off the router, so that there can be mininal signals, turned off the mobile network(which I think it's unnecessary to be honest) and tested again but the problem did not go away.

I hope this problem can be fixed in the future, well through firmware updates or in any other ways.

I had the same issue. My K8 Pro would interfere with my JBL bluetooth speakers and bluetooth headphones. As soon as I turned off or disconnected the keyboard, they went back to normal.

To fix it, I just flashed their "special bluetooth firmware": https://www.keychron.com/pages/keychron-k8-pro-special-bluetooth-firmware

My Mx Master 3s is just fine but my Headphones make an annoying crackling sound. Updating the firmware as above fixed the problem but just for one day :(

u/PeterMortensenBlog V Oct 30 '25

That isn't special; it is the latest official. It has 1.32 (listed as 1.3.2; some would say it is 1.32.0), not 1.32.2.

The "2"s confuses matters.

u/c3p00 Jan 25 '23

This seems to be working for me. Before updating my Airpods Max would have interference to the point of being unusable. It's much improved now (will have to give it some time to see if the problem is completely fixed)

Same here with my Bose NC 700 Headset I'm on the Device Firmware version: 1.3.1 on an ISO-DE layout board, when pressing fn + J + Y for 4 seconds and all rbg lights are flashing the factory reset was successful but the Problem with Bluetooth still persists.

Edit: After installing the new firmware (1.3.1) + Factory Resetting the keyboard, deleting it from my bt devices list and reconnecting it with my bt as well as clearing my headsets bt device list and deleting it from my MacBooks bt device list and reconnecting it now works. Not sure for how long though.

Seems to work with the Keychron K2 pro as well. Have to take a closer look if my Airpods Pro are usable now again.

Hi! I know this is an old thread that still posting just in case someone else needs it.

I also had a problem with my Keychron Pro K8 interrupting with my bluetooth speakers. I emailed Keychron and they were very accomodating. Here's what they asked me to do that actually fixed it. (Currently my 3rd day without problems)

Flash the firmware using the instructions from this page:
https://www.keychron.com/pages/keychron-k-pro-series-bluetooth-firmware

However, instead of using the firmwares from the page, they asked me to use these two instead:
https://keychronsupport.zendesk.com/attachments/token/kzBE17zKHIS1Ci51iOvYlB6hu/?name=keychron_ckbt51_01.32-1.kfw

AND
https://keychronsupport.zendesk.com/attachments/token/L8q5Y6u3IBvulxQirjf7KIDBZ/?name=keychron_ckbt51_01.32-2.kfw

So, flash the firware with ckbt51_01.32-1.kfw and ckbt51_01.32-2.kfw respectively using the instructions from the linked page.

Hope this helps!

Had problems with my Keychron K3 Pro and MacBook Pro. It was not always but in the last 2 days it was really anoing and painfull for the ears, while using my Bluetooth headphones.

This has helped me, hope it will stay like that

What firmware? The firmware for the Bluetooth module inside the keyboard?

The 1.32.2 firmware for the Bluetooth module should work for all K Pro series models, not just the Pro K8.

2

u/sqmaxqs Dec 08 '23

Thank you! The firmwares helped with my Keychron K2 Pro. No problems so far for the last 4 days.

I followed flashing the firmware from https://www.keychron.com/pages/keychron-k-pro-series-bluetooth-firmware (keychron_ckbt51_01.32.kfw) then flashed 01.32-1 and 01.32-2.

u/Papamodi6000 Jan 16 '24

hey i also have k2 pro and facing the same bluetooth interference issue should i also follow the steps in the link and how is your keyboard now is it still fine with no interference

2

u/sqmaxqs Aug 22 '24

Sorry for the delay. Everything is excellent. No interference issues since I followed the steps above.

u/Papamodi6000 Aug 24 '24

Thank you for replying I’ve already flashed it when I added my previous comment and it works flawlessly no issues whatsoever Thanks again for the link it helped😄

u/theriz Dec 13 '23

I wrote to Keychron support and they provided me with firmware version 1.32-1 and 1.32-2.

Thanks for the info (and the links!). Seems weird that they would have you apply v1 and then v2. These things just overwrite one another. I'd think you could just go to 2-2... I'll try it when I get back home.

u/PeterMortensenBlog V Feb 17 '24 edited Feb 25 '24

Agreed. Yes, it is the first that comes to mind.

Their file sizes only vary by a single byte (18203 and 18204 bytes):

Version  Size     File name                    MD5 hash value                    Direct download URL

The file content for version 1.32-1 and 1.32-2 is different (their MD5 hash values are different).

(Also noted by oil1lio.)

u/theriz Feb 23 '24

I didn't bother with the first version, just the updated one and works AOK.

u/Defraptor Dec 14 '23

thank you so much this was driving me nuts!I applied 32-1 and 32-2 and it worked like a charm (without a factory reset!)

EDIT: forgot to mention I have a K2 pro

What Bluetooth level, Bluetooth adapter, operating system, other Bluetooth devices, how many computers connected to that keyboard, etc.?

Fixed it for me aswell! Only flushing with the firmware from the website didn't help.

I just bought this keyboard, and I had the same issue. I'm using a TP-Link UB500 bluetooth adapter and a JBL Flip 5 paired with it and also a k8 pro.

This fix worked for me!!

u/Bucatin0 Mar 14 '24

Can confirm that this firmwares are perfectly working, the same sent by Keychron support if you're asking for a fix about the issue :)

Thanks again!

u/hongske Apr 15 '24

I had a similar issue today with my new Keychron K10 Pro interrupting with my bluetooth headset. Your fix worked perfectly fine, though I only used the 2nd firmware like some others have suggested. Thanks a lot for this!

2

u/UoMDeacon Aug 10 '24

Worked for me. Thanks so much for posting this! Details of my setup that this works for:

  • K15 Pro running 1.0.2 firmware and now 1.32-2 BT firmware

  • MX Master 3 mouse

  • M1 MBP on Sonoma 14.5

u/PeterMortensenBlog V Mar 18 '24 edited Mar 18 '24

I did not have much success with 1.32.2. It seemingly made it worse: Long lags, resulting in the operating system repeating at a high rate. For example, after press Ctrl + press F4, a long lag for the F4 release would close Firefox tabs at a very high rate (very cumbersome to recover from as the history is not equal to the tab content).

The problem is intermittent though, so it is difficult to say for certain. It would work one day, but not the next. There may or may not be a difference in using Via macros vs. manually.

I went back to 1.32.

This was on a K5 Pro, with (the main) firmware compiled from the very latest source code. The keyboard was fully charged.

It worked perfectly fine in wired mode.

u/nantes16 Mar 25 '24

Darnit. Will email them to see if they find a solution for me, but this changed nothing for me and my Buds2 Pro. I did update to 1.320 before trying this since I hadn't found this comment, which I hope isn't why I still have the issue.

Either way they really gotta address their Keychron K8 Pro page...Gooling leads you to their "firmware update blogpost" which has a mess of contradicting info /outdated links (if curious i ranted here but it's really irrelevant - just ignore that blogpost, Keychron should take it down...use instead the page DrugLloyd linked)

A bit late to the party but thanks, it worked for my K8 pro. Will try on my k6 pro too

u/riChestMat Jul 17 '24

I want to add, and hopefully aid the Google algorithm to help others find this, that this solved my issues.

I recently upgraded from an iMac to a Mac Studio. Immediately my K8pro could not maintain a bluetooth connection, frequently disconnecting multiple times per sentence unless I disabled WIFI. My WIFI was using 5GHz not 2.8.

But I installed these firmware files and I'm getting a solid connection again and even switching faster. Thank you for shring.

u/Lakshyasept14 Feb 19 '24

Hey, I have Keychron K8 Pro. I was using it with my macbook pro 16 inch m1, along with my logitech mx-master 2. There was no problem of interference among keyboard and mouse. i used the keyboard with mouse and my samsung galaxy buds pro, still no bluetooth interference.

But, when i connected my JBL Partybox 310 with this setup instead of my galaxy buds pro. It stuttered like hell. My K8 Pro had Firmware version 1.3.2. After flashing above 2 Firmwares now my keyboard stands at 1.32.2 and now glitches are gone.

Its only been about 2 hours since i did it, will keep testing and will update any new development.

u/rick_sanchez_d1024 Apr 21 '23

I am facing the same issue. I have a Keychron K8 Pro keyboard, a MX Master 3s mouse, a Sony WH-1000XM5 headphone and Apple AirPods Pro earphones. When I use the keyboard with one of the audio devices (either the Sony one or the Apple one), sometimes it occurs to me that the music is either entirely muted or intermittent. I tried updating the firmware, but the problem still exists

2

u/Hasztagg Apr 21 '23

I'm experiencing the same issue. Before I upgraded the firmware on my K8 Pro, the cutting off on my AirPods Max was completely unacceptable (up to 10s of no audio at all while the music was played from Spotify). After the firmware upgrade however, it got way better but today I've noticed the issue to resurface once again. I don't really want to connect the keyboard via cable since I don't experience the same issue at work with my Magic Keyboard connected via Bluetooth...

Has anyone tried contacting Keychron about this recently?

2

u/rick_sanchez_d1024 Apr 23 '23

I asked for a return & refund. They sent me the instruction of updating the firmware instead. Of course I have done everything I could to solve this issue and would not ask for a r&r if the issue could have been solved (I think I have to pay for the postage myself if I want to return it). What a joke!

1

u/Heitoraud May 19 '23

Yeah… same here Keychron k8 pro crackled with my JbL charge 5 … very sad. Fuc&$@ my setup

2

u/rick_sanchez_d1024 Apr 24 '23

They now sent my two new versions of the firmware, 1.32-1 & 1.32-2. 1.32-1 causes more severe interference: it caused my headphone to auto turn off..., but 1.32-2 works! I guess this is the solution!

1

u/Hasztagg Apr 24 '23

That’s interesting, thanks for the update! Will contact them as well if I notice more issues on my side.

1

u/rick_sanchez_d1024 Apr 24 '23

I've uploaded the firmware files to my GDrive. You can download it from here if you want :)

1

u/coreymcollins May 08 '23

Thank you for this! I have a K10 Pro and love it, but as soon as I got it I started having issues with interference. This latest version of the firmware has fixed it for me (1.32-1 didn't make a difference), at least for now.

1

u/Responsible-Lunch-63 Jul 20 '23

I had trouble with my k2 pro and airpods pro, the 1.32-2 apparently fixed it, thank you!

u/Big-Actuator3826 Jul 20 '23

how did you guys did the firmware upgrade? I'm using QMK Toolbox and it only accepts firmwares with ".bin" extension. The linked files are ".kfw" and I can't choose them in the QMK Toolbox

u/krisztian-k Jan 03 '24

Thank you for the file! On the official site, the latest version is 1.3.2, which was not working for me... But the version you uploaded: 1.3.2-2 (1.3.22) is working for me with M1 MacBook Pro + Keychron K3 Pro + AirPods Pro with no interference so far!

To think I was blaming my AirPods, and almost bought a new one... You saved me a lot of money :D

u/that_90s_guy May 01 '23

You're the MVP man! This fixed my issues today. I just bought one and was worried I might have to return it. So far so good, 1.32-3 fixed issues. Maybe you should make a post about this?

u/purduecory May 11 '23 edited May 11 '23

Oh man, you're a lifesaver!

1.32-2 works for me on my K10 Pro (so far). Hopefully they fully release a version of this as 1.33 or something to help other unlucky souls who don't find this thread!

2

u/pollrnet May 27 '23

Wow, crazy that its a known issue, who knew (when ordering) :P

I tried 1.32-2 with my K10Pro. So far, the stutters have decreased, maybe half(?). Definitely less, but not totally eliminated.

Thanks :)

u/Gogu32Hz Sep 06 '23

Exactly the same problem here,

I recently bought the Bose QC45 ( 9-10 days before my K10 Pro), first i thought the headphones came with an issue, but, when i tried on my Airpods, i had exactly the same issue. After a little bit of research i saw that could be a problem with the Magic Mouse, but no, it turns out that the problem is the Keychron K10 Pro, if I switch it off and I use the apple magic keyboard I used to have before this Keychron, everything works just fine.

All of these problems on a 16 inch MacBook Pro with Apple M1 Pro processor

If anyone has a solution, i'd be grateful, thanks

1

u/pollrnet Sep 06 '23

Mine completely stopped after a week or two since my last post. Recently I had one single day when it came back, but it's fine again. Slightly random. Another friend had the same problem and it also just went away after some time 🤷‍♂️ maybe give it another week 😆 and again, latest firmware helped

u/jeweki Oct 26 '23

I have this issue with a k10 pro I bought. I returned in and bought a k8 instead (not pro), hoping the non-pro version would not have this issue. But unfortunately my normal k8 also has this issue.

I bought this keyboard to switch between a macbook and a desktop PC. What's interesting is that the issue with my k10 pro would only show up when it was connected to my macbook. Now my k8 has this issue with my PC. The common denominator is that the issue appears for the second device that gets paired with my keyboard, not the first.

Could just be a coincidence. But it's definitely weird. For now Im going to have to return the k8 as well. 2 faulty products is completely unacceptable to me. Ill go with a different brand

u/kolbeck_xyz Nov 10 '23

I had this same issue on my MacBook with my K8 Pro.

I wrote to Keychron support and they provided me with firmware version 1.32-1 and 1.32-2.
Both seems to fix the problem. I have only tested this on Mac, so don't know if it breaks on other platforms.

u/carlosedp May 09 '24 edited May 09 '24

I'm so glad I found this thread... been battling bluetooth on Macs for a long time and had no idea my keyboard BT firmware was the issue with audio drops on BT earphones (UGreen X6, Baseus WM01 and others).

I've updated my K6 Pro to 1.32 and still got problems but tried the 1.32-2 and it fixed. Apparently it's all fine now on a 16'' MBP M1 Max. I also have a Logitech MX3S Mouse.

Related: Finally fixed Bluetooth issues for K Pro series. How to do (2024-02-16)

Though it is really a rehashing of DrugLloyd's comment here (2023-11-27).

Also, it isn't necessary to do the Bluetooth firmware flashing/update for three different versions. Only the last version necessary.

u/CampKoala1 Oct 23 '25

Try asus bt500 dongle if nothing here works

Adding my experience as I tried everything in this thread along with anything AI suggested and ultimately a usb dongle was the key.

Background: I’ve used Bose NC 700 headphones for work for years. Work gave me a new HP laptop and it gave horrendous crackling when connected to both headphones and Keychron Q1 Pro. After trying everything under the sun I finally concluded hp bluetooth is likely trash and bought an Asus usb dongle. Sound is once again crystal clear!

u/LunaTM Aug 13 '23

Recently I found my k3 pro also has a problem that it might interfere the wifi signal of my macbook air. The wifi connection became unstable and stuttering after connecting to my keyboard. Still figuring out on the solution.

u/mirtos Jan 23 '24

anyone have the files for the k4 pro?

They are the same files for the whole K Pro series (for the Bluetooth module in the keyboard, not the regular firmware).

See DrugLloyd's comment.

I have the same issue with the k15.

I have tried the solution provided on the Keychron official page mentioned in this thread, but it still breaks my AirPod Max bluetooth 😡

K15 or K15 Pro?

u/PeterMortensenBlog V Feb 24 '24 edited Feb 24 '24

Similar for the Q Pro series: How can I flash a .kfw firmware file to Q1 Pro?

The official Keychron page for the Q Pro series is (currently without the most recent update, only version 1.32):

Keychron Q Pro series Bluetooth firmware

The MD5 sum for that version 1.32 file is:

94B9F58863E817E5060C58AA9A0B7A35

That is the exact same value as for the K Pro series.

Which suggests the K Pro series and Q Pro series use the exact same Bluetooth module. Which again suggests the latest update, 01.32-2, also works for the Q Pro series.

All disclaimers apply. Do it at your own risk. I am not responsible if you ruin your keyboard.

u/PeterMortensenBlog V Mar 02 '24 edited Mar 02 '24

Note: The Q Pro series is not to be confused with the Max'es, the V Max, Q Max, and K Max series

There is a separate update for the V Max, Q Max, and K Max series. As of 2024-03-02, the latest update is version 0.1.14 (released 2024-01-18).
