## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth every penny! Amazing sound !
*by H***Y on May 2, 2020*

Amazing sound!!! I got two at the same time and it’s really worth the price! The directions are in pictures but follow them exactly and they will pair together. They are also so cute!!! Hint: put them in different parts of the room for surround sound

### ⭐⭐⭐⭐⭐ Namjin!
*by M***I on August 6, 2019*

I freaking love BTS but that's not the only reason to say how good this product is. The sound quality is amazing and it can't get any cuter than having to boop the nose to play/pause. The figurine that comes with it is about the same size and material than the one that comes with the bt21 keyring. It really is amazing and I'm really considering getting another one to use the duo stereo function. Highly recommended to all armys.

### ⭐⭐⭐⭐⭐ stream legends only
*by J***A on July 29, 2019*

I specifically got this to blast the best mixtape of all time, RM’s mono. He is cute, perfect, and his nose is boopable just like his father. 10/10 must buy
