Glastonbury. Leeds. Your back garden? That's right, hold your own festival with this Sony wireless speaker. Whether you're lost in the newest anthem, or you've turned your home into a jazz club, the built-in subwoofer ramps up the bass to make every song sound its best. You can link it to other devices with Bluetooth, so you don't have to stay tied down when your hands should be in the air. The 25-hour battery will keep the music going long into the night, and if the weather takes a turn, its water-resistant design makes sure it'll stay safe from splashes. Better get this party started.
