Review on Bluetooth Receiver JoohcUngir Amplifier Wireless by David Gibbs

These are well made bluetooth modules with good soldering, good solder mask and good headphone and power jacks. All you have to do is plug in headphones or a 3.5mm cable to connect it as line-in to your amp/speakers/TV/etc. to connect, and then plug in your phone charger to power it. The module turns on in pairing mode. Grab your streaming device of choice (mobile phone, etc.) and start searching for Bluetooth devices. This module will appear as "BT5.0 Audio". When your device finds it, simply touch the found device and the pairing process will complete effortlessly. I've paired it with both a 2019 Samsung phone (Bluetooth 5.0) and a regular 2013 Tracfone (Bluetooth 4.1) which I still keep. as a cheap MP3 player and was able to connect to both devices without any problems. It took about 30 seconds for the bluetooth 4 device to finally show the bluetooth module. The Bluetooth 5 device listed the module within a few seconds. After pairing, both devices will connect within 5-10 seconds. I ran this module continuously for over 5 hours to power a pair of headphones and nothing on the circuit board ever got hot and the audio never dropped. Sound quality through a pair of high quality wired headphones was good (I couldn't tell the difference between this module and a direct connection to my phone). socket, they also have solder pads. The power jack has (+) and (-) pins and the headphone jack has LGR (Left, Ground, Right) pins.
