🔊 HiLetgo 3pcs M28 Wireless Bluetooth MP3 Audio Receiver Board BLT 4.2 - Lossless Decoder & Stereo Sound Module with Bluetooth 4.2 Connectivity Review

Considering the raw power consumption and the preamp it sounds great. A little awkward to connect. Usually you have to turn Bluetooth off and on again to turn it back on. It has a very weak sound as there is no built-in amplifier. Add a headphone preamp and a speaker preamp and amp.

They have done a great job adding bluetooth to my work and personal vehicles for music. You can't take calls due to the lack of a microphone, but for the price I can get by without one. The main problem with them is that you have to manually reconnect almost every time you use them, but you get used to it. For the price it's fantastic!

I've had this in my hand for a long time and finally decided to try it. I couldn't turn the preamp or bass volume up that much before this thing just stopped working. Turned the volume or base down and turned it back on. Tried the same with a different preamp. The Drok bluetooth sound card I bought works better but has a lot of background noise.

This little thing is great! Can't believe those expensive store bought ones only have this little thing. I forgot I had them and decided to try them long after the return window. I left the first one running for a few hours and it just stopped working, the second one I used for a few days and the other one I gave to a friend. Not everything is so bad for the price.

I've tried 3 boards and gotten just above a whisper with 40mm 4ohm 3watt bluetooth speakers. One board didn't work at all. I have done extensive research on the remedy and found no reason for this problem. Many argue that an amplifier is not necessary. I question this claim. I wouldn't have this problem if I hadn't spent months developing my product around the board only to figure out what I did. Okay, back to the drawing board. I give two stars for the beautiful blue light.

These little boards are great. Really good sound quality and my setup doesn't require a ground loop breaker between it and the amp. Fantastic value for money. Soldering can be a little tricky if your skills aren't very good (mine are significantly worse). However, this is possible with a little care. I used one of these to make a bluetooth speaker in a small package. I used a small board that allows you to power the bluetooth board with 5v and the amplifier board with 12v. pleasure works.

No buttons, no built-in amplifier, all the useless functions that other more expensive adapters have, there is a 3.5 jack and USB for power, a very simple module, exactly what i need. Using it in my car with a 2013 Nexus 7 in the dash. The Nexus 7's 3.5mm jack is very loud when nothing is being played. This thing fixed everything. Advantages - no buttons, coupling possible at any time. - 3.5mm output jack, many other adapters don't have it. - No built-in amplifier, does not need a large power…

First of all, they are incredibly cheap, so you should be skeptical when buying them. I bought them about 6 months ago. I'm mostly happy with them, but they have some weird quirks that annoy. 1) They MUST be turned off when not actively in use or they will go into a weird frozen state where they won't work until the power is turned off. 2) One in three died within a month. not that big of a problem because they're so cheap, but it's something to be aware of. 3) In the Bluetooth menu they are…
