Easy to add BT to my audio projects

At this price, come on... They all worked – cellphone ready to pair, plugged in power to the module, discovered “BT5.3-Audio” on phone, selected, paired, play music on cellphone, it got received by the unit – all good. After a Bluetooth scan, each unit showed as “BT5.3-Audio” there was no differentiation between the units.The range was about 15’ – fine for earphone or headphone, I looked, and the distributor did not state a range for this device, so be forewarned – or call it a security feature. If you can get over the horrible Chinese female voice and the range issue, you won’t be disappointed. This device’s power jack IS a C type connector. I would think with a modern C power connector, that the ready to pair and paired announcements would be superb and that the range would be impeccable, but they are way underwhelming. Two stars off for the obvious. Peace out.

range is about 6-8 ft. with no obstructions whatsoever. Sound quality is great at 3 ft. but at that rate ill just use a wired connection.

I have to return these. I tried 3 of the 5.I wasn't gonna separate the last 2 boards to test. They come conjoined, mine in pairs. You have to break them apart. Could this be part of the problem? I was careful with the one I separated.One came alone as there were five. That was the first one I tested. It died on me. This was after some testing which determined the range/reception was abhorrent! So I thought okay, maybe that's a bad one. It happens, no biggie. The range issue was the same with 2 of the others. I gave up.My advice is not to waste your money or time on these. Reading the reviews, I feel like I'm in bizarro world. I really wanted these to be good and looked forward to using them on a few projects. It's truly a shame; because the sound quality seemed very good! Nonetheless it's a FAIL!Range in a car maybe isn't an issue. But if you are physically integrating it into an existing radio or putting it behind a dashboard, I can't see these working at all. If my body was between the phone and the exposed board on the counter it lost the connection. If I was more than ten feet away the it dropped.To make sure the problem wasn't my phone I put my JBL Flip4 in the same spot and had no problem. As a mater of fact it was connected while I was researching and eventually going with another product (much more expensive BTW), I had walked into another room maybe 30 feet away when it dawned on me that, hey yeah, this is how Bluetooth Audio is supposed to WORK! lolSAVE YOURSELF, STAY AWAY!

I like how convenient it is. Just hook up to any aux input like computer speakers, usb-c power and it works. One star less, because it would be very convenient if it would be wrapped even in a shrink tube to protect it from short circuit.

Good product if you're looking to create a Bluetooth speaker and want to use your own amplifier. Great price, low input voltage and low power consumption (which means you can drive it from a battery for a few days), small form factor, and excellent quality of audio (as well as PCB quality). You can output the signal using the 3 small pads on the board (be careful to not short these pads!), and you can power it with USB C, which is a great feature!

At 5 for $10 it can't be beat. So far I have hooked up 3 of the boards and each has worked great, An old usb phone charger for power sent by a USB C cable gives a nice quiet power supply, The out put sent to a variety of preamps and amps all worked great. Listened to both MP3 and FLAC files. They both sounded great! I am going to order another set to give as gifts. Couldn't be more pleased. Great buy!
