Overview
A pocket-sized Bluetooth speaker from JBL rated IP67 for waterproofing and dust resistance, with up to 7 hours of battery life plus a 2-hour Playtime Boost mode. It is built in part from recycled plastic and packaged in FSC-certified paper.
The IP67 rating is what sets this apart from a basic budget speaker: it can handle a pool deck or a rinse under a tap, not just light rain. Auracast support lets it pair with other Auracast-enabled JBL speakers for wider sound or stereo pairing with a second Go 4, though that depends on having compatible speakers on hand.
- Up to 7 hours battery, 9 with Playtime Boost
- IP67 waterproof and dustproof
- Auracast multi-speaker pairing
- Made with recycled plastic and FSC packaging
Who it's for
Suits anyone who wants a small, tough speaker for outdoor use, a beach bag, a shower shelf or a campsite, over sound quality or bass depth. Listeners wanting room-filling volume or deep bass should look at a larger JBL model.
Strengths and trade-offs
Drawn from this product's published specifications.
- IP67 rated for water and dust exposure
- Compact enough to carry in a bag or clip on
- Auracast pairing for stereo or multi-speaker setups
- Small driver limits bass depth and max volume
- Auracast pairing needs other compatible speakers
Performance notes
JBL Pro Sound tuning gives the small driver a fuller low end than its size suggests, and the IP67 rating covers both submersion and dust, so it can survive a splash or a sandy beach bag equally well. Playtime Boost trades some volume and mic features for roughly 2 extra hours of battery when needed.
