So this is the Soundcore Select 4 Go speaker… its a 5 watt speaker that gets impressively loud for its size, it actually sounds really good at max volume and it has a battery life of up to 20 hours. If you’re looking for something small and portable to take on the go with you, or if you’re looking for something to use while in the shower, the Soundcore Select 4 Go is a solid pick up.
