Short answer: the Teufel Boomster 2021. It ranks #33 of 73 boombox speakers by sound quality; the Sony SRS-XG500 ranks #45.
What the Teufel Boomster 2021 gets right: Pretty balanced sound, slightly warm. The catch: Not as deep of bass as above ranked speakers. Boosted mid bass compensating for the lack of bass extension.
On the Sony SRS-XG500 side: 30 hour battery life; 10-min quick-charge gives 3 hours. Battery care function stops charging at 90% to extend longevity. Watch for: Thuddy upper bass, not as deep bass as others. Speaker will not remain at max volume and will turn itself down automatically.
Buy the Teufel Boomster 2021 if sound quality matters more than the price. Buy the Sony SRS-XG500 if the price matters more than sound quality.
If battery life is a priority, the Sony SRS-XG500 is rated for 30 hours versus 18 hours for the Teufel Boomster 2021.
