The Soundcore Boom 2 Plus is the tougher option. A fairly light stereo boombox, easy to carry to the beach or park. It is rated IPX7 against IPX5 for the Teufel Boomster 4. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
Why pick the Teufel Boomster 4: A stereo boombox with DAB+ and FM radio, a long battery, splash resistance and a remote with treble control. It supports aptX HD Bluetooth, which the Soundcore Boom 2 Plus lacks. The catch: Side by side with the Teufel Boomster 2021 the sound barely changed, and it has a little less deep bass.
