Wireless speakers

Just pair your phone and the music goes with you. Wireless JBL and Harman/Kardon speakers connect via Bluetooth, charge via USB-C and last all afternoon and evening on a single charge. Small models with a carabiner hang on a backpack, waterproof ones survive rain and a fall into the pool, clock radios wake you up in the morning with your favorite station, and party speakers with a light show fill the whole garden with sound. Multiple speakers of the same brand can be linked into one system.
