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

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 supply. Can be powered by a battery. - Clear sound, better highs and lows than 3.5mm tablets, who would have thought it. - 3 for the price of one. Cons: Only one device can be connected at a time, but that's to be expected.
