Tiny but mighty

I absolutely love this portable speaker! It’s great and easy to travel with, it doesn’t take up space and the battery life is perfect on it. I have a 1B1B apartment and the sound fills up the entire space. I also use the speaker at the pool and beach it gives plenty of sound and bass!! It also comes with a charger so you don’t have to purchase one. Best purchase ever!

Great for laying in bed, listening to tunes.

I love this little device. I can pair it with my phone, tv, ipad with ease and listen to music or shows. It has a long battery life and sounds good. My only cons are it would be better if it said what percentage the battery life is at instead of just saying normal battery level. That and the normal sound mode has a little too much bass.

Compact and good sound
RobinP Posted
Easy to pair. Good sounds. Compact. Controls are easy to find. Mine do not come with a charging cord but I have a dozen so that was not an issue. I use this to boost my TV speakers while doing treadmill workouts. I place this in the water holder and it prevents blasting out the house.

Great speaker bad quality control by Best Buy
techHead Posted
The speaker works well, it is very powerful for its size and has good battery life. The surround sound was why I chose it, it really makes a difference for these small speakers. It is good for general music quality, if you want something with more bass then choose something else. The problem with the quality control by Best Buy was that the original box was smashed, literally crumbled up. The speaker was fine and the item is for me, but imagine if it was a gift, it would be unpresentable! The box had a sticker on it saying it was inspected and please pick first. There was no indication on the website that the item box was damaged, it said new.

Doing research before my purchase proved to be especially helpful in this case. You can't beat this for affordable, loud (but not distorted) sound. It also allows options for music, outdoor and podcast listening.

Great Sound, Poor Longevity
GabrielaG Posted
I bought this in December 2024. It had a really good sound system and was waterproof, but it suddenly stopped working. I’ve tried turning it off and on, disconnecting and reconnecting the Bluetooth, and even charging it overnight, but nothing worked. I had an older version before this one, and that one lasted me over 5 years.
