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, with better dynamics performance. Many of the features are 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. That said, the Bose can sound a bit boomy by default, but you can EQ it to taste. The Marshall might be preferable for its consistent sound at different listening angles, 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, but it compromises on headroom and battery life.
