    • High quality, durable, waterproof!
I recently purchased the Ultimate Ears MEGABOOM 3 Portable Bluetooth Wireless Speaker and I am blown away by its performance. This speaker is not only sleek and stylish, but it also delivers incredible sound quality that fills the room. One of the standout features of this speaker is its waterproof design, making it perfect for pool parties,beach days or kayaking. I love that I can take it anywhere without worrying about water damage. The battery life is also impressive, lasting for hours on end without needing a recharge. The Bluetooth connectivity is seamless and I have had no issues connecting my devices to the speaker. The sound is crisp and clear, with deep bass that really enhances the listening experience. Whether I'm listening to music, podcasts, or watching movies, the MEGABOOM 3 delivers immersive sound that truly impresses. Overall, I highly recommend the Ultimate Ears MEGABOOM 3 Portable Bluetooth Wireless Speaker to anyone in the market for a high-quality, durable speaker. You won't be disappointed with its performance and features. ... show more

I love this speaker and have two of these and one of the Boom 3s. I have had only positive experiences with these speakers. Highly recommend

    • Great sound!
I ordered three different sets of speakers to compare. I ordered these plus JBL and kicker bullfrogs. These were not as loud as the JBL or kickers but we’re plenty loud enough. Plus the sound is much more balanced. Bluetooth is a little finicky, but the stereo function works great. Definitely by two. I really like that they are lightweight and bulletproof. ... show more

    • Not loud enough and spotty Bluetooth connection
Honestly, for the price I feel like it’s not loud enough and the Bluetooth connection isn’t very good either. Signal cuts out if you get too far. Even under a tent at the beach if you sit a few feet away from the speaker it starts to cut off. I do like that you can connect multiple speakers together, but again, they can’t be too far away from each other. As a single speaker it isn’t worth it in my opinion. ... show more

    • Two tries for a “certified” refurbished. No luck for a good product.
Not sure how these are being certified and approved for resale. I just received my second Wonderboom 3. I’ve had one for years now. It still works beautiful. I’m trying to order a second to pair it with for outdoor wellness classes I teach. Thought I’d try the refurbished route to save some money and save the earth. First one I received, speaker is a bit blown. Bass crackles when you get to just a low - medium volume. And overall sound cuts in and out at higher volumes. So I processed an exchange. That process was great. Received a replacement in two days. Buuuuut, the replacement won’t charge or even turn on. Entirely useless. Won’t power up at all. What gives? ... show more

    • 6 stars
If I could leave 6 stars, I would. Not only did it look brand new, they included the charging dock which was originally sold separately. Also it sounds incredible when you pair 2 of these together. I already owned one so I knew I'd like the sound quality, the battery life isn't bad and for the price this is a steal considering you'd probably never break it with how durable and waterproof it is. ... show more
