Since these Bluetooth modules suffer from many issues such as poor output, noise etc. I purchased the below listed 3 Bluetooth boards from Robu to check which one is the best-
1. Blackboard VHM-314 Bluetooth 5.0 MP3 Decoder Board （Type C）for ₹ 99.00
2. MP3 Bluetooth 4.1 Decoder Board for ₹ 109.00
3. MH-M28 Wireless Bluetooth Audio Receiver Board Module BLT 4.2 mp3 lossless decode for ₹ 125.00
After personally testing these 3 boards, I can say with full confidence that the VHM 314 is the best BT audio receiver because-
1. It has a much better quality sound output than other boards. The STEREO (not MONO) output is clear and crisp.
2. There is no irritating lady voice. Only a low-volume audio clip is played when switched on, connected/disconnected, which is not irritating.
3. There is a USB C female jack which makes it easier to plug into your existing charger cable. Nevertheless, we can solder wires for battery power.
4. The output volume is higher compared to other two boards.
The audio quality is 90% of what I get from the 3.5mm jack of my laptop or mobile. I wish it were the same as 3.5mm output but anyways, the difference is not noticeable and you get very good stereo output.
You will get noise in output if you use the same power supply from your amplifier. Connect this board to a separate power supply to get rid of the noise. OR you can use a DC- DC isolator like b0505s-1w between power source and the module to remove the noise.

The sound quality is not that great and bass is lower than with direct headphone jack output..also there is a audible whine noise when nothing is playing but the led is blinking..not tje white noise which every Bluetooth device has..also as mentioned in the description the usable voltage range is from 3.7 to 5v..so when using with a battery directly the module shuts off when the battery reaches 3.75 volts.. so the battery isn’t fully used and has to be charged fully before using again.. note.. please don’t connect the module through a usb when a battery is connected to the module as there is no charging circuit in the module and if you connect the module through a usb while a battery is connected full 5v will go to the battery which might lead to an explosion..other than these the sound quality is pretty good for the price and also consumes low power while in use..

i was tested this product and surprisingly good at this price. Although i had received this with some minor defects like cheap solder patch which was fixable. Sound quality not best but with price its quite good, i genuinely recomend this.
