Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 91 boombox speakers by sound quality (rated 4.4/5) at $349.95 and is still sold new; the Teufel Boomster 2021 ranks #46 (rated 3.4/5) and is discontinued, so it is only an option used.
The JBL PartyBox On-The-Go 2 Plus is the better-sounding pick. Well balanced with strong vocals, and its front-firing bass ports give it cleaner, smoother bass than other PartyBoxes, so even the Punchy bass boost setting never overpowers the vocals. It links with other speakers (Auracast), which the Teufel Boomster 2021 cannot. It has an adjustable EQ, which the Teufel Boomster 2021 lacks. Watch for: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder.
The Teufel Boomster 2021 is the lighter, tougher choice. At 8.3 lbs (3.75 kg) it weighs much less than the JBL PartyBox On-The-Go 2 Plus at 14.2 lbs (6.45 kg). It is rated IPX7 against IPX4 for the JBL PartyBox On-The-Go 2 Plus.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality; the Teufel Boomster 2021 is no longer sold new.

The Two Speakers In Full
JBL PartyBox On-The-Go 2 Plus: $349.95 Amazon eBay
Older model: the JBL Partybox On the Go (ranked lower, rated 3/5).
Pros: Well balanced with strong vocals, and its front-firing bass ports give it cleaner, smoother bass than other PartyBoxes, so even the Punchy bass boost setting never overpowers the vocals. It gets a touch louder than the PartyBox Encore 2. EasySing AI vocal removal strips vocals from any song on the speaker itself, with 25%, 50% or 100% removal, and the included rechargeable wireless mic has a tight pickup pattern that rejects handling noise. A removable 34Wh battery shared with the Encore 2 and PartyBox 120, a claimed 15 hours, a padded shoulder strap, USB-C playback and charging, a 3.5mm aux input, Auracast and a light show.
Cons: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder. There is no wired microphone or guitar input, so more mics means buying JBL’s EasySing mics separately, and AI vocal removal is disabled while the speaker is linked to other speakers over Auracast. Real world battery life is closer to 7 hours at 80% volume with lights and bass boost on. IPX4 only covers splashes, the grille dents easily, and the battery must be installed for it to run even when plugged in.
