I purchased this about a year ago. I'm selling it because I no longer use it. I believe it works without any problems. Model number: PTM-BTLLTR This device functions as both a transmitter and a receiver. It can be set up as either. Compatible standards: Bluetooth 5.0 | Communication distance: up to 50m | Supported codecs: SBC/AAC (receiver mode only) / QualcommⓇ aptX / QualcommⓇ aptX Low Latency. Dimensions: (W)64 x (D)22 x (H)52 (mm) | Weight: Approximately 40g. I believe there was a vertical stand, but it's not included, so please consider only what's in the photos. Also, please note that an AUX cable is not included. For my convenience, shipping will be via Sagawa Express. Also, I sincerely apologize, but those in Okinawa and other remote islands, please refrain from purchasing. Please consider this after understanding. Furthermore, the last shipping date this year will be December 24th, 2025 - December 25th, 2025, and shipments after that will be made on or after January 6th, 2026. Please be aware of this when considering your purchase.
