The JBL Go 4 is the latest version of JBL’s smallest portable Bluetooth speaker, sized to fit in a pocket or clip onto a backpack strap. It’s rated IP67 for full dust and water protection, so it keeps working at the beach, the pool, the shower, or anywhere else where the average portable speaker would short out. Battery life is about 7 hours per charge, with USB-C charging and Bluetooth 5.3 handling the wireless side.

A waterproof speaker perfect for all your escapades and then some
The IP67 rating is the biggest reason to pick the Go 4 over a non-waterproof Bluetooth speaker. That handles shower steam, getting splashed at a pool, or dropping it into a kayak taking on water, all of which would kill most non-rated Bluetooth speakers. Even after a session at the beach, you can rinse the Go 4 under a tap to get sand and saltwater off without damaging anything inside.
The Go 4 sounds about as good as a speaker this size can. JBL tuned it to push the mid-bass and treble forward, keeping vocals and percussion clear rather than drowning them out the way they would on a cheaper speaker. The volume is enough to fill a bathroom or a porch, but not really a backyard party, which fits with what a single-driver portable speaker should do. JBL’s Portable app lets you tweak the EQ if the default tuning isn’t your taste, and it also pushes firmware updates.
