Review on AKSONIC Bluetooth Receiver for Speakers - 5.0 Wireless Audio Adapter with 100 Feet Long Range, Built-in DAC, aptX HD, Low Latency, for Home Stereo, TV - Desktop RCA Optical 3.5mm AUX by Pranav Osman

This item was purchased to add a BT connection to your sound system. It worked well when I used it for the first time after receiving it. "This sound system has not been used in the last 7 months therefore Aksonic has not been used either as it was not connected to the network. tried to use it today (December 30th) and it seems to be blocked. (Turns on and off but doesn't go into pairing mode and the "hard reset" and forced pairing steps in the manual don't do anything - confirmed after 12 tries.) Note that there's a one-month return window and a six-month support window.
