Can't go wrong with this purchase.

Sounds good for the size. Fills a mid-sized room easy. Remember this thing only has 40mm drivers so it won't compete with the bigger speakers. When paired with another speaker it sounds really good. If you can grab two of these for $50 a piece, do it. You won't regret it.

Solid speaker at great price

It's a nice compact Bluetooth speaker at a great price! You can choose outdoor mode or podcast mode for best sound, long battery life 14 hrs, convenient c charging port. I used a Wonderboom 3 for a long time, this one is even better.

Small but very capable

Very satisfied with the product quality and value for money. Small in size but surprisingly big on sound. Surround sound with wide range of frequencies producing great sound quality.
