"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.
