Onn Pro X Large Boom Boombox vs Teufel Boomster 2021

Last updated: October 21, 2026

Short answer: the Onn Pro X Large Boom Boombox, if you are buying new. The Teufel Boomster 2021 measures as well as it (#51 vs #49 of 113 boombox speakers, 3.4/5 vs 3.4/5) but is discontinued, so only consider it used; the Onn Pro X Large Boom Boombox is still sold new at $199. The Teufel Boomster 2021’s replacement, the Teufel Boomster 4, is rated 3.4/5.

Onn Pro X Large Boom Boombox vs Teufel Boomster 2021

What the Onn Pro X Large Boom Boombox does well: A powerful, waterproof party boombox with a 20 hour battery and light modes at a low price. It links with other speakers (Auracast), which the Teufel Boomster 2021 cannot. It has an adjustable EQ, which the Teufel Boomster 2021 lacks. The catch: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.

The Teufel Boomster 2021 is the lighter pick. A waterproof stereo boombox with FM radio, a long battery and stereo pairing. At 8.3 lbs (3.75 kg) it weighs much less than the Onn Pro X Large Boom Boombox at 17.2 lbs (7.8 kg).

Buy the Onn Pro X Large Boom Boombox if you want one new; the Teufel Boomster 2021 is discontinued, so only look for it used.
