Bluetooth audio receiver (supports optical digital and RCA output), bundled with a USB Bluetooth transmitter. I am selling this because I no longer need it after reviewing the overall setup of my home audio equipment. You can connect it to audio equipment that doesn't have Bluetooth and listen to music from your smartphone through your audio system. As a bonus, I'm also including a USB Bluetooth transmitter, so you can connect a PC without Bluetooth to your audio system (I used it that way, so I'm selling them as a set). The items are the same as when purchased, including the box. ・Main unit ・MicroUSB cable for power (Type A) ・RCA to 3.5mm audio cable ・3.5mm audio cable ・Microfiber bag ・Box Plus, a USB Bluetooth transmitter as a bonus (I will send it even if you don't need it). http://www.tsdrena.com/audio/hem-hc-btratx/ ↑This is the manufacturer's website. Retail price: 12,800 yen, I bought it for 8880 yen. As you can see in the photos, there is some paint peeling on the edges. Please check the photos. It doesn't affect the use at all. I plan to ship it by wrapping the original box in bubble wrap and putting it in a paper bag. Thank you for your consideration. *Please note that I am not offering any discounts.
