Short answer: the JBL Boombox 3 Wifi for output, the Teufel Boomster 2021 for balance. The Wifi is the loudest speaker in the category and has a slightly better frequency response than the non-wifi version, but its bass is boosted with a dip at 160Hz. The Teufel sounds pretty balanced and slightly warm, yet its bass is not as deep, with boosted mid bass compensating for the lack of extension.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality; the Teufel Boomster 2021 is no longer sold new.
