> What's the problem of Logitech with Bluetooth?

From what I've seen, Logitech devices seem to have the transmit power set very high. Like use-it-from-multiple-rooms-away high. I have no idea why they do this, but it tends to make my PCs take a bit longer to detect other Bluetooth devices in the area. But not to the point that they won't connect or function. This includes pretty janky stuff like my hand-built keyboard that uses nice!nano boards.

It seems that combining this with the AirPods' existing issues in 2.4GHz-heavy environments and you've got a recipe for connectivity problems.

I see. But there is a maximum tx power that Bluetooth devices can transmit legally, is it just high tx power or something else?

Regardless, my issue can be solved via software: it's not "always connecting because of high tx power". I have other Bluetooth devices paired and none of them try to connect to other peers when I forcibly disconnect them until I explicitly hit connect or do a power cycle. On the other hand, the Logitech one does, which is literally the single reason for me to ditch it and never recommend a Logitech device to anyone again.

There's a maximum transmit power for the 2.4GHz band (without an operator license). If that maximum isn't exceeded, I don't necessarily see a problem here, unless Logitech is doing something really really sketchy on the EM spectrum. Implementing broken Bluetooth without calling it Bluetooth isn't forbidden as far as I know, for example, though it'd be quite a shitty thing to do.

If this notice is specially written for Airpods and not just any Bluetooth headset then it might as well be an Airpods problem.

I've never had issues with the dongles that come with Logitech on any of my devices. Bluetooth is terrible for high-frequency input and audio streaming anyway, so the in my experience the dongles are a much better solution.

All bluetooth audio dongles work like that, from all manufacturers. They'll automatically connect to the first open audio devices they see, so you shouldn't leave the dongle plugged when not used. It is very infuriating when you have a neighbor that plugs their dongle all the time and it constantly connect to your bluetooth headphone the moment you put it to pairing mode.

Just why? I get it if it connects when first powered on or the other device is first detected within range, yet why does it immediately reconnect when I disconnect?

My headphones don't have this behavior, my home Bluetooth speakers (not dongle, speakers themselves have BT) don't do it, my Bluetooth audio enabled TV doesn't do it, then why does the dongle do?

I don't see any logical explanation.
