Short answer: the JBL Partybox Encore 2. It ranks #4 of 113 boombox speakers by sound quality (rated 4.4/5); the Teufel Boomster 4 ranks #50 (rated 3.4/5).
The JBL Partybox Encore 2 is the better-sounding pick. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. Watch for: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The Teufel Boomster 4 is the longer-running, lighter option. 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 2. At 8.3 lbs (3.75 kg) it weighs much less than the JBL Partybox Encore 2 at 14.1 lbs (6.4 kg). It supports aptX HD Bluetooth, which the JBL Partybox Encore 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 2. It is rated higher for sound quality than the Teufel Boomster 4.
