According to our Bluetooth speaker expert
Thanks to the 360-degree sound, you hear the music clearly from anywhere in the room.
The Outdoor Boost allows you to hear powerful sound and you clearly hear the voices in Podcast Mode.
You can easily use the speaker at the beach, thanks to the IP67 certification.
You can't charge your smartphone to the speaker, because it doesn't have a power bank.
