Short answer: the Turtlebox Ranger. It ranks #65 of 164 medium speakers by sound quality, rated 3.5/5, at $250. The Teufel Rockster Go 2 ranks #91, rated 3.2/5, at $129.99, $120.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Turtlebox Ranger: Smoother frequency response than the other Turtlebox speakers. The tradeoff: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers.
The Teufel Rockster Go 2 is the lighter option. At 1.6 lbs (0.74 kg), the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. At 1.6 lbs (735 g) it weighs noticeably less than the Turtlebox Ranger at 2.4 lbs (1.09 kg). It has an adjustable EQ, which the Turtlebox Ranger lacks. It plays in stereo from a single unit, unlike the Turtlebox Ranger. The catch: There is no companion app or 3.5 mm input.
Buy the Turtlebox Ranger. It is rated higher for sound quality, and the $120.01 saving on the Teufel Rockster Go 2 is not enough to make up the difference.

The Two Speakers In Full
Turtlebox Ranger: $250.00 Amazon eBay
Pros: Smoother frequency response than the other Turtlebox speakers. Has magnets for attaching it to things. Appears to be quite tough
Cons: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers. Overpriced. Heavy for the size, likely due to the toughness

Teufel Rockster Go 2: $129.99 Amazon eBay
Older model: the Teufel Rockster Go (ranked lower, rated 2.6/5).
Pros: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Independent listening found a balanced, clear midrange and tuneful bass at sensible levels.
Cons: There is no companion app or 3.5 mm input. Reviewers found it loses some definition at maximum volume, and the claimed battery figure is optimistic for loud outdoor playback.
