I was travelling on a plane (so I’m presuming 600 mph?) and, of course, Bluetooth earphones worked fine with my tablet. Though I guess we were in a vacuum.
If you were outside the plane travelling at that speed, would the earphones still be able to connect to the tablet?
Does relative speed affect the connection, or is the only important factor the distance between the two devices?
In addition, how far would it work in space? 😆

I’m confused how you thought you managed to stay alive in a vacuum.
I’m also confused what you’re actually asking, since Bluetooth only has a range of a few metres and connection takes a finite time, so you’d never notice if you could connect to a speaker you passed at 600 mph.
But assuming you had an ultra high power Bluetooth device that had a range of many miles, then realistically no it wouldn’t matter if you were moving relative to the thing you wanted to connect to. Light is really really really fast, fast enough to go round the earth 7 times in one second. A plane is essentially stationary as far as light / radio waves / etc are concerned. It makes no difference if there is air or the vacuum of space separating the devices, radio waves happily travel across both. If you had an ultra high power Bluetooth thing, and a magical spacecraft that could travel at half the speed of light or something and gunned it towards your speaker, then Bluetooth wouldn’t work as the signal would be Doppler shifted to a frequency range where the equipment doesn’t work any more. (Like how an ambulance siren or train changes pitch as it goes past, a similar thing happens to light when you get to speeds close to light speed)
