Yes, many Marshall speakers are Bluetooth compatible. This means that you can connect your phone, tablet, or other Bluetooth-enabled device to the speaker wirelessly and play music through the speaker. To do this, you will need to put the speaker into pairing mode and then select it from the list of available Bluetooth devices on your device. Once connected, you should be able to control the volume and playback of your music from both your device and the speaker. It's worth noting that not all Marshall speakers are Bluetooth compatible, so you'll want to check the specifications of the specific model you're interested in to be sure.
