## Description

EVERBOOM Cobalt Blue

Review: I should be giving desertcart one less star for their lies on ship windows, but UE doesn’t deserve the knock, because this company consistently brings it and improves. They take customer input seriously and alter products for it. This Everboom was a response to critiques of “not enough bass” for their boom and megaboom speakers, which are honestly great. Even the tiny wonderboom speaker is great. If you can catch these on sale, they are an incredible value. I got this one for 214.00 $55 bucks off, making it about the megaboom price. This new generation of UE speakers is great. No, it doesn’t play for 20 hours at max volume, but it does play for longer than 20 hours below the half volume, so use your brain when considering that an actual critique. The bluetooth connection on UE speakers is FLAWLESS. The speaker connects and pairs easily, and there are zero gaps or delays in the playback/stream. This speaker is great for that extra bass for a richer ambient music/party experience. I got this for a boat day coming up, and the durability was why I went with UE yet again. The design is minimalist and fun, they are truly waterproof and float, and they are compact enought to strap to a bag or cooler or hook easily. This one is a little heavier but still slight for what it provides. There was a time where you just couldn't achieve this kinda sound on a portable speaker, let alone a wirelessly connected one. This speaker sounds superior to the old JBL smooth surfaced base and satellite speakers you had hardwire connections and a giant power source to plug in. Technology is a trip. Buy this speaker. Even better if you buy on sale. The app is nothing special, but does the things it says: EQ and party pairing hundreds of these together. I intend to buy another immediately given how amazing this sound was. For audiophiles, I can’t account for the terrible reviews, other than to say your expectations should be in the portable speaker category, not the home theatre or movie theatre sound, or even the sound that comes from nose cancelling bose headphones. But that’s not what this product is for. This is a social lubricant speaker: it is intended for group events, parties, cookouts, boat days, and for that purpose they are nearly perfect products. Also- UE hasn’t passed on overhead or materials costs spikes on to their customers. The wonderboom, boom, and megaboom have held steady price points for a decade. That’s enough for me to be a loyal customer. Well done, UE! Also, the colors are great, I just wish we could get the same megaboom colors for the Everboom and Epicboom series. *UPDATE*** Had this speaker all summer and fall. Amazing. Strategic placement will also draw out a better sound, just fyi. Found a new use for it: white noise speaker for whatever app you have on your phone. I listen to audiobooks around the house with this on as well. Dropped a number of times being clumsy on a hardwood floor. Zero damage. Even cheaper than I bought it during summer now.
Review: Easily the best portable speaker UE has made yet. It’s louder than the Megaboom and much more portable than the Epicboom. It's fully waterproof (IP67), floats, and the 360 sound means there are no "dead spots" in the room. The Cobalt Blue is a great deep shade. If you want something rugged that still sounds like a high-end home speaker, get this.

*by N***R on 17 July 2025*

Extremely disappointed with the lack of volume and sound quality as well as the battery life. When I had the Everboom at full volume in a small space I was still able to have a conversation with someone at normal speaking level. I honestly thought that my phone's volume was acting up or I needed to restart it, thinking that maybe my phone was the culprit of the low volume. But no, this speaker is just that quiet We use a Mega Boom at my work to listen to music and I keep the volume at a little over half which is perfect for the 10,000 sqft building I work out of. When I compared the Everboom to the almost 10 year old Mega Boom, the Everboom was noticably quieter than the Megaboom at the same volume level and has a buzzing noise when the volume was increased to match the megaboom's ability. The battery life is beyond bad, I played this speaker at its quiet "full volume" for 45mins and it dropped from full charge to 70%. My wonderbooms are almost louder and better sounding than the Everboom. I've returned the Everboom and will be on the look out for the Mega Boom. Skip this speaker, it's overpriced and frankly the lower priced models are better in both volume and sound quality and that's coming from someone who isn't that picky about sound quality.
