The Marshall Middleton is another portable Bluetooth speaker that retains the manufacturer's signature design. It's a tad larger than the Marshall Emberton or the Marshall Emberton II, likely because of its quad-speaker setup that's advertised to include two tweeters, two woofers, and two passive radiators. It can also reproduce a more extended low-bass than the Emberton lineup. Plus, its bass and treble adjustments give you a bit more control over its sound. Its USB-C input/output is a nice touch, especially if you want to charge other devices on the go, which you don't find with many speakers on the market
