Re: totally turn off bluetooth function
Base on Bose's reply , theoretically it is possible that Sleepbuds already disabled the bluetooth function after falling into phone free mode.
Using EMF/RF meter to test is just for confirmming. On logic we only can say it make sense Sleepbuds totally disable bluetooth function under phone free mode in current design. But the test result from meter is base on fact . The result is what I care about finally. The reply from Bose is to make all things sounds resonable.
If you trust Bose a lot , I think you could just forget this issue and enjoy your Sleepbuds. If you are cautious , mabye you could buy a meter to double check. The meters can test all electronic product .I think it is worth investing.
Just for your reference.
