Know before you buy
Yes, the speaker is rated IP67, meaning it is fully waterproof and dustproof. It is designed to float, so you don't have to worry if it accidentally falls into a pool or lake.
Podcast Mode adjusts the speaker's EQ settings to prioritize vocal frequencies. This makes spoken word content, like podcasts and audiobooks, sound much clearer and easier to understand.
The WONDERBOOM 4 has a wireless Bluetooth range of up to 131 feet (40 meters). This allows you to keep your phone in a safe, dry place while the speaker is out by the water or on a patio.
It is designed to deliver 360-degree sound, and you can engage the 'Outdoor Boost' feature to specifically tune the audio for open-air environments. This helps the sound carry better when you are away from walls that would normally reflect and amplify the bass.
No, the WONDERBOOM 4 does not feature a built-in microphone. It is designed strictly for high-quality audio playback rather than speakerphone functionality.
