Our read on this product
Forget constantly searching for a charger. This speaker has an incredible 32-hour playtime, meaning your music can soundtrack everything from a weekend camping trip to a long day at the beach without interruption.
Beyond the marathon battery life, it delivers a powerful 40W stereo sound that brings outdoor gatherings and parties to life. Its IPX7 waterproof rating means you don't have to worry about splashes by the pool or unexpected rain showers, making it a worry-free companion for any adventure.
What makes it stand out
- Its 32-hour battery life significantly outlasts most portable Bluetooth speakers, reducing the need for frequent recharging during extended use.
- The IPX7 waterproof rating offers robust protection against immersion, making it more suitable for poolside or beach use than water-resistant alternatives.
When this isn't the right fit
- The 40W stereo sound is powerful, but may be overkill for casual listening in quiet indoor environments.
Real-world notes
- Sound quality is consistently praised, with many noting the impressive bass for its size.
- The rugged build and waterproofing give owners confidence to use it in a variety of outdoor settings without concern.
Take your music anywhere, rain or shine, for days on end.
