Short answer: the Teufel Rockster Cross. It ranks #23 of 115 large speakers by sound quality, rated 4.2/5, at $199.99. The Xdobo X8 Max ranks #83, rated 2.9/5, at $105.99, $94 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Xdobo X8 Max is the tougher option. A feature packed waterproof boombox with a huge battery, power bank output, and enough volume for outdoor background music. It is rated IPX7 against IPX5 for the Teufel Rockster Cross. The catch: The voicing is bass-heavy with thin, boosted highs that can turn harsh, and reviews report distortion rather than clean dynamics when pushed hard.
The Teufel Rockster Cross is the better-sounding pick. A splash resistant speaker with fairly neutral, vocal focused sound and punchy, controlled bass that suits rock and jazz. It supports aptX Bluetooth, which the Xdobo X8 Max lacks. The tradeoff: 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 $94 with the Xdobo X8 Max does not make up for the sound-quality gap.
