Reminds me of my friend who has bought a shit load of 1.5v AA lithium batteries. The buck converters in those little bastards wreak havoc with every speaker around. His TV remote disconnects my Bluetooth headphones every time.

Weird. Wonder if they chose 2.4ghz as their time division for the switching, because it’s a cheap and common frequency to source for.

They won't be switching at that frequency, but they're probably putting off harmonics up to very high frequencies due to very sharp switching.
