Could be louder
Color: Squad
I picked this up because I wanted something small and easy to throw in a bag, and it does a lot right for its size. Sound quality is actually pretty good, and the bass is better than I expected from something this small. It works well for listening around the house, in the garage, or outside when you’re close to it. Battery life has been solid, and I like not having to worry about it getting splashed or dusty. It feels well made and easy to use, and pairing was quick. The only real downside for me is the volume. It just doesn’t get loud enough for bigger spaces or when there’s a lot of background noise. For a small room or personal use it’s fine, but it struggles if you’re trying to fill an area or use it with a group. Still a good little speaker, just keep expectations realistic when it comes to volume. That’s why I’m giving it 4 stars instead of 5.

Great sound for the size, durable build, and easy Bluetooth pairing
Color: Black
Impressive sound for such a small speaker, with better bass than I expected. Good option if you want something portable without giving up too much audio quality. I’ve been using this mainly for casual listening around the house and outside, and while camping, and it connects to Bluetooth quickly and reliably every time—no pairing issues so far. Sound quality is solid for the size. It gets reasonably loud and has decent bass compared to other ultra-compact speakers. It’s not going to replace a larger speaker, but it performs well within its size class. Build quality also stands out. The unit feels durable, and the waterproof/dustproof design makes it a good choice for outdoor use. The integrated strap is a nice touch for carrying or hanging it. Battery life has been good, and it charges quickly, which makes it easy to grab and go without worrying about downtime. Id say its a good value for the price. The buttons also are easy to use and give nice feedback when pressing them. Cons: Limited bass compared to larger speakers (expected for the size) Bottom line: If you want a small, durable Bluetooth speaker that sounds good and works reliably, this is a solid choice. Definitely better than most of the cheaper knockoff options in this size range.
