If you like your portable audio gear to match your guitar rig, Marshall's new Bluetooth speaker fits the bill. The Kilburn not only handles music-playing duties via the aforementioned wireless connection, but its design resembles one of the company's guitar amps. From the speaker grill to the outer shell, gold-accented controls and guitar strap handle, the device looks just like a miniature version of what you'd see on stage. Sure, Marshall's been selling speakers for a while now, but this is its first portable option. Inside, a 4-inch woofer, a pair of 0.75-inch tweeters and three amps (two 5W and one 15W) handle those playlists for up to 20 hours before needing a charge. It won't arrive until next month, but when it does, the Kilburn will set you back $300.
