Apple's latest iPhone release has brought renewed attention to Bluetooth technology, with its unusual looking AirPod wireless earbuds dividing opinion.
Bluetooth is handy and easy to use - but where did it come from?
The technology came to life in 1998 as a way to connect devices the way wires do - just without the wires.
The first specification was released around a year later and in the coming years, "hands-free" started becoming a very real thing.
By 2012 annual Bluetooth product shipments had surpassed 2 billion.
Now, according to Apple, we don't even need a headphone jack.
But is it safe?
Bluetooth headsets do emit radiation, but not much - in fact, it's 1000 times less than what comes from your mobile phone.
And with Apple betting heavy on it, you can expect more products to get on board.
