JC-AUDIO Bluetooth receiver. I was enjoying good sound easily by streaming music from my smartphone to this receiver via Bluetooth and connecting it to my audio system's amplifier. I had no complaints and the sound quality was excellent. I am selling it because I have purchased an amplifier with a built-in Bluetooth function. Operation has been confirmed. Recommended for those who want to enjoy good sound easily from their smartphone. - Brand: JC-AUDIO - Power adapter: Included - Antenna: Yes - Optical input - Output terminals: L/R line out Headphone jack - Power switch: Yes The main body case is made of metal and shielded, and it has a solid weight. The power adapter has a capacity of 5V6A, providing a reliable build. Thank you for viewing.
