Review: Another Great Speaker from Ultimate Ears! - I’ve owned several UE Boom models over the past 10 years and have purchased them as gifts for others. The MegaBoom is my favorite with its rich 360 degree sound, long battery life, and the fact that it’s waterproof and floatable out at the pool. I’ve never actually plunked one in the pool (I’ve used it in the shower though), but I feel confident knowing if it got knocked in, it would be fine. Party Up through the app is amazing and getting even better over the years — I don’t recall the stereo option, but I now can either mirror the speakers so that each has all channels, or I can opt to put them in stereo mode which is pretty darn cool. I would still like UE speakers if they were only standalone devices, but the fact that I can link up to 150 devices and place them in various places for gatherings makes it an undeniably great product! I’ve even borrowed extras from family & friends for big parties. I just bought a new MegaBoom 4 and thought it would be fun to compare to my MegaBoom 3. Honestly, they’re both amazing, and while I could hear a little more depth of sound from the 4 (maybe), the sound was very very similar. If you own a 3, adding a new one is great, but I probably wouldn’t recommend spending on a new one simply to upgrade. I was a little disappointed that the 4 can’t use the Power Up base. It has a USB-C connection, but no ability to dock to a base. I suppose that really shouldn’t matter, but I’ve just found it much easier to ensure it’s always charged if I plop the speaker on its dock and not having to fish out a cord that has fallen behind a piece of furniture because I unplugged the speaker. Silly? Yeah, I know. It’s just a personal preference and I wish they had kept that feature. The MegaBoom device does not have a mic, so it cannnot be used for 2-way communication. The 4 does have the ability to speak into your phone and broadcast your voice through the speaker using the Ultimate Ears app. If you’re in the market for a new portable Bluetooth speaker, don’t hesitate — it’s absolutely worth it. Hint: they’re pretty much indestructible, so if you find one on desertcart Resale (formerly desertcart Warehouse), it’s a great way to get one at a terrific bargain and it’s likely in good shape. Floating in the pool is going to be even better this summer. Can’t wait!
Review: Nice speaker - Really nice speaker. Has great sound and can get to a high volume. I like that you are able to connect it to other Megaboom speakers and that it's waterproof. Really nice lookjing and not heavy. The only thing is I wish it came with a charger.
