Bose SoundLink Max vs Marshall Middleton II

The Bose SoundLink Max is slightly better for most people than the Marshall Middleton II. The Bose has a longer continuous battery life, and it can get considerably louder at max than the Marshall. Many of the Marshall's features are also matched or bested by the Bose, such as build quality (though it's a bit susceptible to scratches), and wired and Bluetooth connectivity. Plus, you can add a second for a stereo pair, which the Marshall can't do. Still, the Marshall offers better directivity, meaning it sounds pretty consistent regardless of your listening angle, and it weighs about one pound less with a more compact frame. Like the Bose, you can EQ it and use it for phone calls.
