Top 5 Positive Customer Reviews for 32 usb
Just like advertised. It really amplifies the sound and expands the soundstage with quality headphones. I should try a little more before I give the final verdict but so far impressive. Highly recommended seller.
Genuine Fiio k1. It was posted quickly, then the package was returned (for some reason) before leaving China but the seller promptly sent another one. I'm very satisfied with the service and the product.
