What with the growing popularity of wireless headphones and wearable devices, Bluetooth is more common than ever. In fact, according to the Bluetooth Special Interest Group, which oversees the development of the technology, 13.9 billion Bluetooth-enabled devices will ship by 2020.
Good news then that the technology has just been improved. Bluetooth 5 is more powerful than ever, with enormous potential for the Internet of Things and wireless music listening alike.
So what can it do? And when can you get hold of it? Read on and find out.
What is Bluetooth 5?
Bluetooth 5 is the next iteration of Bluetooth, the wireless technology that's found in smartphones, smartwatches, tablets, wireless headphones and speakers, laptops, desktop computers and more.
Bluetooth lets your devices talk to each other wirelessly. When you receive a notification on your smartwatch, it's come from your phone over Bluetooth, for example.
It also lets you fire tunes to a wireless speaker, so you can listen to tunes at home, in the park, or on the beach.
This being the latest version of Bluetooth, it's a lot more powerful than its predecessors.

How powerful is Bluetooth 5?
Plenty powerful. Compared to its predecessor (Bluetooth 4.2 Low Energy), it's twice as fast, has four times as much range, and can transfer eight times as much data.
If you want hard stats, we're talking a bandwidth of 2Mbps. In practice, this means speedy and reliable over-the-air connectivity, leading to faster firmware updates and data uploading.
Thanks to the greater range of around 800 feet (or 240m), your wireless speakers and headphones will work much further away from the sound source than with Bluetooth 4.2 Low Energy. It also allows for whole-home coverage for Internet of Things devices like security cameras, smart fridges, smart thermostats and more.
And because of its more efficient use of broadcasting channels on the increasingly popular 2.4GHz band, it opens the way for "richer connectionless, beacon-based Bluetooth solutions", according to the SIG. In other words, expect more wireless connectivity wherever you go, from sports stadia to shopping centres.
You can connect more than one pair of wireless headphones to a single sound source over Bluetooth 5. If your device has the right functionality, like Samsung's Bluetooth Dual Audio feature, you can adjust the volume of each independently. Very handy for sharing and journeys by train or plane.
Bluetooth 5 can also detect interference at the edges of the 2.4GHz and neighbouring LTE band, and automatically prevent it. Which should make for clearer music listening from any wireless device.
Which devices are compatible with Bluetooth 5?
There aren't many Bluetooth 5 devices at the moment. The Samsung Galaxy S8 is the first phone to work with the technology, but at the moment, it's all on its lonesome. Without any Bluetooth 5 headphones or speakers around, you can't take advantage of the greater range or faster speeds as yet. But these should start arriving before the end of the year.
The good news is that you can use the Galaxy S8's Bluetooth Dual Audio feature with any Bluetooth speaker or headphones. Just pair them with the phone as you usually would, then select 'Dual Audio' from the menu in the top right of the screen.
Will Bluetooth 5 improve sound quality for wireless speakers and headphones?
Sadly not. The focus is on the Internet of Things and greater connectivity, but the SIG makes no mention of improved sound quality. That's not to say music fans won't get any benefits, however. Wireless headphones and speakers will work much further away from the sound source, and you can stream the same audio to more headphones/speakers simultaneously.
Bluetooth 5 could also improve battery life. Because it's more efficient, it'll use less energy, which should mean longer battery lives for wireless speakers and headphones. But we'll have to try them out for ourselves to confirm this.
