Bose SoundLink Max vs Marshall Kilburn III

The Marshall Kilburn III and the Bose SoundLink Max are both great portable options for Bluetooth speakers, but there are slight differences that can influence a buying decision. The Bose is sturdier, boasting an IP67 rating for submersion in water. It has a better app too, which allows you to simply pair other SoundLink Max speakers in stereo or party mode configurations without using Auracast. That said, the Marshall has better directivity and a longer battery life that stretches close to the 24-hour mark. Ultimately, both speakers have balanced frequency responses and excellent portability, so your decision could come down to any of the above, or even their very different aesthetics.
