Know before you buy
Yes, the speaker is fully waterproof. It is designed to handle being submerged and will float if dropped in a pool or lake, making it safe for water-based activities.
The 360-degree design projects audio in every direction, which helps maintain consistent volume and clarity across a wider area compared to directional speakers. It is particularly effective for filling outdoor spaces like patios or campsites.
The 20-hour estimate is based on moderate volume levels. If you consistently play music at maximum volume, you should expect the battery life to be shorter than the advertised maximum.
While 147 feet is the maximum range in an open, unobstructed environment, physical barriers like walls or large objects will significantly reduce this distance. For the best connection, keep your device within a clear line of sight to the speaker.
The MEGABOOM 4 is built with a rugged exterior specifically for outdoor use. While it is designed to withstand bumps and drops, it is not indestructible and should still be handled with reasonable care.
