This review is from: DROK DC 5V-35V BT 4.2 Bluetooth Wireless Audio Receiver Module with Case. As always, drok has the best value for money. Plug into a micro USB port for power, or plug directly into a transformer or battery source! I love flexibility and I love modular freedom. The build quality is excellent, the soldering is ideal. I highly doubt this thing will wear out anytime soon. Audio available via 3.5mm stereo auxiliary cable. But I'm using this for an instant bluetooth receiver that connects to basically any bluetooth or wired connection. Purchasing this pre-assembled amp card saved me from spending half a day looking for tools, measuring, cutting, finding material, and sanding the case for the $3 bluetooth card. And to top it off, the price is spot on! The sound quality sounds great. At the same time, I noticed that music sometimes appears and disappears again. like a wave At first I thought it was poor Bluetooth reception. But to be honest, and in all honesty. My problem is not related to this block. I accidentally hooked it up as an input to feed a couple of large PA amps and then a speaker array that's still not big enough to handle the power of the PA amps. So my amps are turned down. Maybe the input to the amps is actually fine and it's my amps themselves that are muted so low that the music actually comes and goes. Further testing is required. I will update if necessary
