Short answer: the Tribit Stormbox Micro 3. It ranks #6 of 62 small speakers by sound quality (rated 4.2/5) at $49.98 and is still sold new; the Sony SRS-XB13 ranks #45 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SRS-XB13’s replacement, the Sony SRS-XB100, is rated 2.9/5 at $44.
The Tribit Stormbox Micro 3 is the better-sounding, deeper-bass option. PartyUp and Auracast party mode link multiple speakers. Its bass reaches about 62Hz before falling 10dB, against 88Hz for the Sony SRS-XB13. Alan Ross Reviews measured it at 93dB at full volume, against 88dB for the Sony SRS-XB13. It is rated for 24 hours of battery against 16 for the Sony SRS-XB13. The tradeoff: Bass is thuddy and distorted by default and needs EQ.
The Sony SRS-XB13 is the lighter option. A removable strap hangs it from a bag or bike. At 0.6 lbs (255 g) it weighs noticeably less than the Tribit Stormbox Micro 3 at 0.7 lbs (330 g). The catch: Not much bass, and the sound is muddy.
Buy the Tribit Stormbox Micro 3. It is rated higher for sound quality and still sold new, while the Sony SRS-XB13 is discontinued.
