This is a fraudulent product. It says it's a stereo 2.0 channel, but it's already mono with a 3.5mm jack. Also, there is a JTK-904-B002-V1.2 mono AMP board inside the speaker box, and the input is mono, and the output simply splits one mono AMP output into two.
This is a complete scam product. It's better to refrain from making a purchase. The manufacturer and this store are engaging in a dirty business of selling fraudulent products.
