Who Should Buy This#
The JBL Go 4 occupies the sweet spot between phone speakers that sound flat and larger speakers that won't fit in your pocket. It delivers JBL's signature Pro Sound in a package smaller than a deck of cards, with waterproofing that lets you take it literally anywhere. Competing pocket speakers at this price lack the IP67 rating, Bluetooth 5.3, or the brand's audio heritage.
Perfect for:
- Travelers and commuters who want a speaker that disappears into a bag pocket and survives airport TSA and rainy walks
- Shower and pool users who need IP67 waterproofing to play music safely around water every day
- Outdoor adventurers who want a lightweight speaker for hiking, camping, or picnics without worrying about drops and dust
- Desk workers who want better audio for video calls and background music without a bulky desktop speaker
Design & Build Quality#
The JBL Go 4 sports a compact rectangular shape wrapped in durable fabric with bold JBL branding and accent colors. At 3.71 x 2.98 x 1.66 inches and just 190 grams, it genuinely fits in a jacket pocket or the palm of your hand. The build feels solid despite the featherweight body, and the fabric exterior resists everyday scuffs and scratches.
The redesigned integrated carrying loop sits on the top corner, making it easy to clip onto a bag strap, carabiner, or lanyard. Side-mounted buttons for power, Bluetooth pairing, and volume are tactile and easy to locate by feel. The USB-C charging port sits behind a sealed flap to maintain the IP67 rating. JBL also made the Go 4 with recycled materials, reducing its environmental footprint without compromising build quality.
Key Features#
JBL Pro Sound with Punchy Bass#
The Go 4 packs a 45mm full-range driver with 4.2 watts of output power. For a speaker this small, the audio quality is genuinely impressive. Vocals are clear and detailed, mids are present without muddiness, and the bass response extends down to around 82Hz. It won't shake a room, but it fills a kitchen, bathroom, or campsite with surprisingly rich sound that leaves phone speakers in the dust.
The frequency response stretches from 90Hz to 20kHz, covering the full vocal range and most musical instruments with clarity. Crank it up and the Go 4 stays composed without the distortion that plagues cheaper pocket speakers.
IP67 Waterproof and Dustproof Protection#
IP67 means the Go 4 is completely sealed against dust and can survive submersion in up to 1 meter of water for 30 minutes. Take it in the shower, set it poolside, or bring it to the beach without a second thought. Sand, rain, splashes, and accidental drops into water are all shrugged off.
This is the same IP67 rating found on flagship smartphones, and it gives you freedom to use the Go 4 in environments where most electronics would fail. No protective case or waterproof bag needed.
Bluetooth 5.3 and Auracast Multi-Speaker Pairing#
Bluetooth 5.3 delivers a stable, energy-efficient wireless connection with improved range over older versions. Pairing is instant, the connection holds steady through walls, and the low-latency codec keeps audio in sync with video content on your phone or tablet.
The Go 4 also supports Auracast, a newer Bluetooth broadcast technology that lets you pair multiple compatible speakers together. Connect two Go 4 units for true wireless stereo, or link even more for a multi-room or party setup. The JBL Portable app provides EQ customization so you can tune the sound profile to your preference.
7-Hour Battery with USB-C Charging#
The built-in rechargeable battery delivers up to 7 hours of continuous playback on a single charge. A full recharge takes about 3 hours via the USB-C port, using any standard USB-C cable you already own. For a speaker this compact, 7 hours is more than enough for a full day at the beach, a weekend camping trip, or a week of desk-side listening at moderate volumes.
