Short answer: the Onn Medium Party Speaker Gen 2, if you are buying new. The Teufel Boomster 2021 ranks higher than it (#46 vs #59 of 91 boombox speakers, 3.4/5 vs 3.1/5) but is discontinued, so only consider it used; the Onn Medium Party Speaker Gen 2 is still sold new at $90.
The Teufel Boomster 2021 is the lighter choice. At 8.3 lbs (3.75 kg) it weighs noticeably less than the Onn Medium Party Speaker Gen 2 at 11 lbs (5 kg). It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2.
What the Onn Medium Party Speaker Gen 2 does well: Under $100 with LED lights synced to music. It links with other speakers (Party Sync Mode), which the Teufel Boomster 2021 cannot. The catch: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2 if you want one new; the Teufel Boomster 2021 is discontinued, so only look for it used.
