Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 113 boombox speakers by sound quality (rated 4.3/5); the Teufel Boomster 4 ranks #50 (rated 3.4/5).
The JBL Partybox Encore Essential 2 is the better-sounding pick. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. The catch: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The Teufel Boomster 4 is the longer-running, lighter pick. A stereo boombox with DAB+ and FM radio, a long battery, splash resistance and a remote with treble control. It is rated for 23 hours of battery against 15 for the JBL Partybox Encore Essential 2. At 8.3 lbs (3.75 kg) it weighs much less than the JBL Partybox Encore Essential 2 at 13.7 lbs (6.2 kg). It supports aptX HD Bluetooth, which the JBL Partybox Encore Essential 2 lacks. Watch for: Side by side with the Teufel Boomster 2021 the sound barely changed, and it has a little less deep bass.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality than the Teufel Boomster 4.
