Short answer: the Bogasing S8 Pro Max. Both are rated 4.2/5 for sound quality (#24 and #23 of 120 large speakers), and the Bogasing S8 Pro Max costs $169.99 against $199.99 for the Teufel Rockster Cross, with sound quality a draw, the lower price decides it.
The case for the Teufel Rockster Cross: 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 Bogasing S8 Pro Max lacks. Watch for: Outdoor mode can sound somewhat harsh due to the 4kHz peak.
The Bogasing S8 Pro Max is the longer-running, lighter option. A three way stereo speaker in an aluminum body with a wide soundstage, punchy detailed sound and clean output at full volume. It is rated for 30 hours of battery against 16 for the Teufel Rockster Cross. At 3.4 lbs (1.55 kg) it weighs noticeably less than the Teufel Rockster Cross at 5.3 lbs (2.4 kg). The tradeoff: Its tuning is bright: the 3D mode pushes the mids and treble hard, can sound sharp or tiring at higher volumes, and sometimes adds an echo effect to vocals.
Buy the Bogasing S8 Pro Max. Both are rated the same for sound quality, and it costs $30 less than the Teufel Rockster Cross.
