Pros
- Ultra-portable design at just 192 grams—genuinely pocket-sized without feeling cheap or hollow
- Impressive bass response for its class, thanks to integrated bass boost and JBL's tuning expertise

Yes, the speaker can play audio while connected to power, though it takes roughly 2.5 hours for a full charge. The charging port doesn't interfere with the speaker grille.
JBL rates it for freshwater submersion. Saltwater and chlorine can degrade seals over time, so rinse with fresh water if exposed and allow complete drying before storage.
In open spaces, you get 30+ meters without obstacles. Walls and interference reduce this to 10-15 meters indoors. Bluetooth 5.3 is stable and rarely drops connection in normal use.
