JBL Go 4 Portable Bluetooth Speaker
About this product
The JBL Go 4 Portable Bluetooth Speaker is an ultra-compact wireless speaker with a sealed, dust and water resistant body. It suits people who want a small portable Bluetooth speaker for travel, the shower, a picnic or a desk, and who value size over raw volume.
How much does the JBL Go 4 Portable Bluetooth Speaker cost?
When we last checked in October 2026, the JBL Go 4 Portable Bluetooth Speaker was typically selling for about $40 – $55 in the US. That is an approximate range, not a quote: the retailer changes prices often, and colour, size or storage options can move it up or down.

Key features
- Ultra-portable size: the speaker is small enough for a pocket or the side pouch of a backpack.
- IP67 rating: IP67 means it is dust-tight and rated for immersion in water up to one metre for 30 minutes, so beach and poolside use are covered.
- Up to 7 hours of playtime: the brand rates the battery at up to 7 hours on a single charge.
- Playtime Boost: a tap on this mode adds up to 2 more hours, according to the manufacturer.
- Stereo pairing and Auracast: two Go 4 speakers can be paired for stereo, or several Auracast-enabled speakers from the brand can be linked together.
- Recycled materials: the speaker uses post-consumer recycled plastic and fabric for the grille, and the packaging is FSC-certified paper printed with soy ink.
What we like
- Dust and water sealing that covers sand as well as splashes.
- Small enough to carry daily without thinking about it.
- Can grow into a stereo pair or a multi-speaker group.
- Recycled content in the body and simpler packaging.
What to consider
- Seven hours is modest; a long day out will need the boost mode or a recharge.
- Bass and maximum volume are limited by the small enclosure.
- Boost modes generally trade some sound fullness for extra time.
- There is no mention of a microphone for calls; check the listing if you need one.
Who should buy it
The JBL Go 4 Portable Bluetooth Speaker suits solo listeners and small groups who want music in places a bigger speaker would be a burden: a bike ride, a bathroom shelf, a tent. It is also a simple gift for a student.
Skip the JBL Go 4 Portable Bluetooth Speaker if you want to soundtrack a party, need more than nine hours between charges, or want heavy bass. A mid-size speaker with a larger battery will serve better.
How it compares
The smallest tier of portable speakers is where the JBL Go 4 Portable Bluetooth Speaker sits. Basic pocket speakers in this tier are often only splash resistant and cannot link to others, while this model has full dust and water protection and group play. Mid-size cylinder speakers cost more and weigh more but play louder and longer. Large outdoor speakers add much more power and battery. A newer generation in the same series exists with lighting and a higher protection rating, so compare the two before choosing.
What to check before you buy
- Charging cable type and whether a charger is included.
- Colour selected; this listing is black.
- That any speakers you want to link support Auracast.
- Dimensions and weight for your pocket or bag.
- Warranty for the JBL Go 4 Portable Bluetooth Speaker, and the retailer’s return policy.
