Amazon is offering a major discount on Marshall’s Middleton portable Bluetooth speaker, bringing the rugged speaker down to $149.99 for Prime members.

That’s a 53% discount from Amazon’s listed $319.99 price, making this a particularly interesting deal if you’ve been looking for a larger portable speaker with Marshall’s signature design and 360-degree sound.

The Black and Brass Marshall Middleton is currently marked as an Early Prime Big Deal, with the $149.99 price available exclusively to Amazon Prime members. Amazon’s listing also shows an additional $10 instant discount for approved Amazon Store Card applicants, which could bring the price down to $139.99.

What you get for $150

The Marshall Middleton is designed as a portable speaker that can deliver substantially bigger sound than typical compact Bluetooth speakers. It uses Marshall’s True Stereophonic technology to produce multidirectional stereo sound, while physical bass and treble controls let you adjust the sound directly from the speaker.

The speaker is also built for outdoor use. It has an IP67 rating for dust and water resistance, so it can handle the kind of conditions you’d expect from a portable speaker used around a pool, at the beach or outdoors.

Battery life is rated at more than 20 hours, and Marshall includes a quick-charge feature that can provide additional playback time after a short charge. The USB-C connection can also be used to charge another device.

The Middleton is not a tiny travel speaker, either. It weighs around 4 pounds, giving it a more substantial footprint than many small portable Bluetooth speakers. That extra size is part of what makes it suitable for buyers who want fuller sound without moving to a stationary home speaker.

Is the Marshall Middleton worth buying at $150?

At its original price, the Middleton occupied a much higher-end part of the portable Bluetooth speaker market. At $149.99, the equation is very different.

You’re getting Marshall’s distinctive design, multidirectional stereo sound, physical tone controls, IP67 protection and more than 20 hours of battery life for about half of Amazon’s listed price.

There is one thing to keep in mind: the Middleton is an older model. Marshall has since introduced the newer Middleton II, which adds features including longer battery life and newer wireless connectivity. That makes the $150 price on the original Middleton particularly important: this deal makes the previous-generation speaker significantly cheaper rather than merely a little cheaper.

For someone who mainly wants a rugged, powerful portable speaker with Marshall styling, the original Middleton becomes much easier to recommend at $149.99.

And if you’re already an Amazon Prime member, there’s little reason to wait around if this is the speaker you’ve been considering. Deal pricing can change, and Amazon is currently labeling this one as an Early Prime Big Deal.
