Princeton PTM-BTLLTR aptX Low Latency Bluetooth Transceiver Unit Brand: PRINCETON I purchased this at Edion earlier this year, but it doesn't suit my usage environment, so I'm selling it. It is an unopened item. Since it is an unopened item, I cannot accept cancellations or returns after purchase, so please purchase only if you agree. Regarding the product, there are no included accessories. Everything in the images is included. Please feel free to comment if you have any questions. Due to my irregular schedule, I may be late in responding to comments and shipping. Thank you for your understanding. I will also be listing this on other sites, so it may be removed without notice. Regarding packaging and shipping... I basically pack items compactly. I will also use recycled materials and processed cardboard boxes. I plan to ship using a Yu-Packet Plus dedicated box. I will pack it carefully using cushioning materials! Thank you. https://www.princeton.co.jp/product/multimedia/ptmbtlltr.html
