Bose's SoundLink Plus is in the upper-middle of its SoundLink lineup, and to me, it's the perfect size. This speaker features four passive radiators, which help it produce a huge bass response, which is exactly what you need for an outdoor soiree. If you're by the pool, the SoundLink Plus can handle accidental drops in water thanks to its IP67 rating, which makes it dust- and waterproof.

Though it can survive brief immersion in water, the SoundLink Plus floats for easy retrieval. Additionally, the SoundLink Plus promises 20 hours of playtime and features a USB-C port for reverse charging, so you can plug your phone in to charge if you need some extra juice.

JBL's Charge 6 speaker is packed with features, including Auracast, USB-C reverse charging, lossless audio via a wired connection, and 28 hours of playtime. The Charge 8 has an IP68 durability rating, making it capable of surviving drops in water for an extended period. This feature is especially useful for outdoor use, so you won't have to worry about spills or accidental water exposure.

This Sony Bluetooth speaker is on the smaller side, which is great if you want something that's easy to lug around. Despite its small frame, it delivers big sound and promises 12 hours of playtime. You can orient the Ult Field 1 vertically or horizontally, and its IP67 durability rating makes it waterproof, surviving submersion up to 3 feet for up to 30 minutes.

Beats' latest Bluetooth speaker delivers big bass in a small and stylish frame. With 24 hours of playtime and an IP67 durability rating, the Beats Pill can play all night without you needing to worry about accidentally spilling a drink on it.

The Beats Pill also features native Find My for iOS and Android, and pairing two speakers together enables Amplify or Stereo mode for a bigger, louder audio experience.

It doesn't hurt to have a larger Bluetooth speaker lying around, and this one features party lights, 24 hours of playtime, and a handle for carrying. The Soundcore Boom 2 has an IPX7 rating, meaning it can withstand submersion in up to 3 feet of water for 30 minutes. The good thing is that the Boom 2 floats when dropped in water, so it's easy to retrieve.
