Amazon Spring sale is almost over — 7 last-minute Bluetooth speaker deals from $49

The Clip 4 is a wicked little speaker that clips to your bag so that you can take it anywhere you want. There's 10 hours of battery life so it'll last you through any hike you might take it on. We found some great sound for its size in our JBL Clip 4 review as well, with a surprising amount of bass. I also happen to really like the way that it looks, with its giant keyring styling going a long way in setting it apart from other small Bluetooth speakers.

The Wonderboom 4 is built for the outdoors with a rugged design and sturdy build. We really liked the speaker in our UE Wonderboom 4 review, especially the surprisingly bassy sound that you might expect from a larger speaker. 16 hours of battery life means you'll be able to get through most of the day on a charge.

This deal brings a long-awaited discount to the Beats Pill. We had a Beats Pill hands-on, and found a speaker that has (as you might expect) some massive bass and a slick look. Battery life is respectable at 24 hours, and its waterproofing makes it perfect for pool parties and outdoor use.

Sony's ULT line is big, bassy and loads of fun. The ULT Field 1 is a great entry into the family, and when we went hands on with the ULT Field 1 we found a powerful little speaker with some big sound. Battery life is solid as well at 12 hours. This deal puts the speaker at its lowest price ever.

The UE Boom 4 speaker is a waterproof speaker than can deliver 360-degree sound with deep, accurate bass. It's battery can last for up to 15 hours and we like that it's rated IPX7 waterproof and it's drop-proof up to 15 feet. Did we mention it can also float? The Red model is just $9 shy of its all-time price low.

The Bose SoundLink Flex 2 is a compact and powerful Bluetooth speaker with a durable design. This 1.2-pound speaker is water and dust proof and delivered great sound quality in our SoundLink Flex gen 2 review. I love how easy it is to use the custom EQ, so I can really dial it in to a sound profile that I love. Add in 12 hours of battery life and you have a great deal.

This is more than just a Bluetooth speaker. Bose has packed in some extra smarts, letting the SoundLink Revolve+ II connect to helpful voice assistants like Alexa. It also pumps out some seriously good audio, with loads of big, deep bass. You can stream higher-quality audio thanks to its Wi-Fi connection, but there's still Bluetooth mode for using with your phone. It has good battery life too, with 17 hours on tap. This $100 discount is an epic deal on a very good Bluetooth speaker.
