The Galaxy S8 and the Galaxy S8+, which were announced earlier today, are the first commercial smartphones in the world to feature Bluetooth 5.0 connectivity. It's a huge connectivity upgrade over Galaxy S7 and S7 edge's Bluetooth 4.2 connectivity. Bluetooth 5.0 offers substantial gains in speed, range, and music quality.
The new version of Bluetooth theoretically offers twice the speed and four times the range. However, that's not the only new thing in the Galaxy S8 and S8+. These smartphones can also stream audio wirelessly to two Bluetooth speakers or headphones simultaneously, also allowing users to control volume on both the headphones separately.
