Short answer: the TOZO PE1. It ranks #21 of 62 small speakers by sound quality, rated 3.5/5, at $22.99; the JBL Go 4 ranks #30, rated 3.2/5, and costs $49.95, so there is little reason to consider the other one.
The TOZO PE1 is the deeper-bass, longer-running choice. A very cheap, light mini speaker with full waterproofing, a carabiner and app EQ. Its bass reaches about 68Hz before falling 10dB, against 82Hz for the JBL Go 4. It is rated for 12 hours of battery against 7 for the JBL Go 4. Watch for: Battery life is about 12 hours in use, far short of the claimed 32 hours.
The JBL Go 4 is the lighter pick. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. At 0.4 lbs (190 g) it weighs noticeably less than the TOZO PE1 at 0.5 lbs (248 g). It links with other speakers (Auracast), which the TOZO PE1 cannot. Watch for: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
Buy the TOZO PE1. It is rated higher for sound quality than the JBL Go 4 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
