I review Bluetooth speakers for a living, and these Prime Day deals are utterly unmissable — save up to $130 on JBL, Marshall, Soundcore, and more

I awarded the JBL Xtreme 4 a delicious 4 stars in my review last year. Yes, I reviewed this speaker a year ago, but I haven't stopped thinking about it. Everything about the Xtreme 4 is iconic: the bass, the party mode, the design. It's the gorpcore 40W bass speaker of my dreams. I'll say it now: the Xtreme 4 is the GOAT of portable speakers.

The JBL party doesn't stop there. JBL's awesome Boombox range is like the Xtreme line on steroids. In our 4-star review, we loved the booming bass and the Boombox 3's ability to fill a large outdoor area. Although it's a heavy speaker, the rugged design and all-day (24 hour) battery life means it'll keep the party going regardless. It'll play even in torrential rain — it's IP67 rated.

The Boom 2 was already an absolute steal, and now that it's $40 off? A speaker of this caliber at just $89 is unheard of — I get my hands on enough speakers to know that by now. The Boom 2 has a massive 80W power, meaning it will go loud. Like the much pricier JBL options, the Boom 2 has a 24 hour battery life and IP67 rating, so it'll be able to follow you anywhere.

Marshall consistently makes some of the best audio gear out there, and the Stanmore III is no different. This awesome amp-lookalike speaker has a 3.5mm jack input and RCA input, so you can hook it up for even higher-quality music. The speaker has designated bass and treble dials so you can turn up the bass all the way if you so desire.

Yes — another JBL speaker. Well, that's because JBL just doesn't miss with its Bluetooth speakers. Although the Flip 7 came out earlier this year, the Flip 6 shouldn't be forgotten about. Especially at this awesome price. It's now below $100, which is an awesome deal for this pocket-sized 30W speaker. It's IP67 and has a 12 hour battery life, meaning it's perfect to chuck in your backpack for all day outdoor listening.

(DJ Khaled voice) Another one! JBL is dominating this list. The JBL Go 3 achieved an impressive 4-star rating in our review, which praised its affordability, portability, and waterproofing. It's literally small enough to fit in a jeans pocket. It has a surprising battery life of 5 hours and is IP67 rated, meaning it's perfect to be a reliable little shower speaker.

No, this is not the same speaker as the Stanmore III mentioned above. Marshall just has a vibe, and all its speakers gotta match that vibe, alright? The Acton III, like its bigger sibling the Stanmore III, has individual bass and treble adjustment dials. The Acton III has an impressive 60W speaker output and is just 10 inches long.

This Bluetooth speaker has an impressive 20-hour battery life and an "Outdoor boost", which increases bass to fill outside areas. The IP67 rating combined with this "Outdoor boost" makes this the ideal speaker for living it up in the park or at the beach, and at this price, it's kind of a shoe-in.
