Short answer: the Teufel Rockster Cross. It ranks #23 of 126 large speakers by sound quality, rated 4.2/5, at $199.99. The Bumpboxx Thump ranks #81, rated 3.2/5, at $161, $38.99 cheaper, which does not close the gap in sound quality.
The Bumpboxx Thump is the longer-running choice. A compact, retro styled boombox with a very long rated battery, water resistance, RGB lights, and a carry strap. It is rated for 32 hours of battery against 16 for the Teufel Rockster Cross. The tradeoff: No independent measurements or tested reviews have been published, so its tonal balance, bass extension and real output can’t be compared with ranked speakers.
The Teufel Rockster Cross is the better-sounding, lighter pick. A splash resistant speaker with fairly neutral, vocal focused sound and punchy, controlled bass that suits rock and jazz. At 5.3 lbs (2.4 kg) it weighs noticeably less than the Bumpboxx Thump at 7.1 lbs (3.2 kg). Watch for: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
Buy the Teufel Rockster Cross. It is rated higher for sound quality, and saving $38.99 with the Bumpboxx Thump does not make up for the sound-quality gap.
