The SoundLink Max is Bose’s answer to the market’s request for a portable speaker with enough output to own a backyard. The passive radiators on each end extend low-frequency response lower than you’d expect from the cabinet size, and at maximum volume the speaker remains controlled without breaking up — a feat smaller portables fail at 70% volume. Bose Immersive Audio creates a stereo widening effect that makes the single-cabinet design feel like more than a point-source speaker.
IP67 rating means full immersion resistance up to 1 metre for 30 minutes, so pool-deck, beach, and boating use are covered without paranoia. The carrying strap mounts securely via stainless steel D-rings and doubles as a shoulder carry for commutes. USB-C charging keeps the cable count low; a USB-A port can top up a phone from the internal battery.
Twenty hours of battery life at moderate volumes and a handle-equipped carry system make this the outdoor speaker for a group trip. PartyMode pairs two SoundLink Max speakers for a true stereo pair. Voice control works via Alexa and Google Assistant without pressing a button, though the ambient sensitivity is less precise outdoors at distance than indoors.

Nathan Hughes –
Sounds much larger than it looks. The passive radiators on each end give real bass extension and the high-end stays clear at high volume. IP67 means I’ve used it at the beach and in the rain without concern. At 6.6 lbs it’s heavy for a “portable” speaker but the carry strap makes it manageable.
