This is the Bluetooth-compatible SU-6. I'm selling this item, which I collected as a hobby, because I don't listen to audio as much anymore. It hasn't been used much and I think it's in good condition. Equipped with the ES9038Q2M, it has a clean and crisp sound, making it suitable for any type of music. All terminals and remote control operation were working well. Thank you. - Brand: S.M.S.L - Model: SU-6 - Connectivity: USB, Optical Digital, Coaxial, Analog Output - Wireless Connectivity: Bluetooth compatible - Color: Silver - Included items: Original box, remote control, BT antenna, power cable, instruction manual (English).
