Overview
Anker's Soundcore Boom 2 is an 80W outdoor Bluetooth speaker with IPX7 waterproofing, a floatable body, and a claimed 24 hour playtime, aimed at backyard and beach listening rather than indoor hi-fi use.
Two units can link for a stereo pair, which is a genuine differentiator at this price rather than a marketing add-on.
- 80W outdoor speaker with dedicated subwoofer and BassUp 2.0
- IPX7 waterproof, floats in water
- Up to 24 hours playtime plus phone power bank function
- Pairs two units for stereo sound via Partycast
Who it's for
Good for backyard, pool, or camp listening where volume and bass carry over open air, and for anyone replacing a smaller portable speaker that felt thin outdoors. Less suited to buyers wanting a compact pocket speaker, since this is built around a subwoofer for outdoor throw.
Pros and cons
- Bass rated above similarly priced JBL and Bose speakers
- Floats and survives full submersion, not just splash exposure
- Doubles as a phone power bank via built-in battery
- One reviewer found max volume lower than expected
- RGB lighting is a novelty most will rarely use
Performance notes
A dedicated subwoofer paired with BassUp 2.0 processing pushes low end that carries across open ground, while the app's Pro EQ lets owners dial the mids and highs back in. The IPX7 rating and floating hull mean it survives full submersion briefly rather than just splashes, and the built-in power bank can top up a phone when the speaker itself still has charge to spare.
