The Marshall Action 3 speaker combines the looks of a traditional Marshall amplifier with the features of a high end wireless speaker. The top of the speaker has individual controls for volume, bass, and treble, as well as a tactile power switch. In addition to Bluetooth and Wi-Fi, the Marshall Action 3 features a 3.5mm auxiliary input to plug in an analog audio device, which makes it a versatile option for playing back audio from almost any source. It's also compatible with the Marshall Bluetooth App so you can customize your sound settings, group your compatible speakers, and play audio from all your streaming platforms with ease.
