Nothing kills the vibe of a beach day faster than forgetting the music, which is why shoppers are snapping up this portable speaker while it’s 30% off ahead of Prime Day (June 23 through June 26).
The Ultimate Ears WONDERBOOM 4 was practically made for sand and surf. It’s IP67-rated, waterproof, dustproof and floatable, so nothing gets between you, a good playlist and a sunny summer day.
Don’t let the speaker’s compact size fool you. With a 4.5-star rating on Amazon, users love the audio quality. One user says, “I put it in the shower. Loud. I put it by the pool. Louder. I dropped it in the pool. It floated. Still yelling.”
The Ultimate Ears WONDERBOOM 4 is the small but mighty speaker perfect for everyday use. From solo shower songs to beach day bangers, this speaker is ultra-portable with 360-degree sound that follows you everywhere.
Equipped with multiple sound profiles and modes for all your listening needs, it can be tuned for outdoor environments, chill podcasts or paired with another WONDERBOOM for doubled-up sound.
The wireless Bluetooth speaker’s design ensures your soundtrack will never be interrupted. With up to 14 hours of playtime off of one charge and a 131-foot (40-meter) range, you’re free to roam, dance, and play all summer long.
Plus, it’s dirt-resistant — but if your beach days tend to get extra sandy, this protective Lebakort Storage Case adds another layer of defense. Regardless, you’ll love the sound this speaker gives off.
“This little speaker has power,” one happy reviewer wrote. “Read the reviews and they are not lying. Little bean (as we are calling it) bumps! Clear acoustics; bass isn’t choppy. Great purchase!”
If you’ve been looking for a small speaker with crisp, bassy sound to throw in your beach tote this summer, now may be the perfect time to cop one while it’s 30% off.
