dTrend and The Pokemon Company have released an official Poke Ball Bluetooth Speaker on the official Pokemon Store website in South Korea.
The Bluetooth Speaker is able to play music from your very own smartphone. A single charge will last for 5 hours. Speakers are located on the back of the Poke Ball, a pretty smart design choice.
You can order the speaker from Pokemon Store Korea here for 29,900 won (USD28) (ships within South Korea only).
