DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY

Needed a new aux cable for my car because my other one took out and this one works great and just as it should. It's the perfect length and doesn't get caught up in everything. Works just as I expected and very happy with it.

I’ve been using this Drok Bluetooth audio module for a few days now, and it’s been working great. It connects easily to my phone and the sound quality is solid for what it is. I installed it in a 10-year-old Makita jobsite stereo that originally had no Bluetooth. I wired the audio output directly to the radio’s internal AUX input by tapping into the 3.5mm jack PCB—worked perfectly and kept the install clean. For power, I tapped into the battery connection PCB and added a bulkhead rocker switch on the side of the radio to turn the module on and off independently. The stereo runs on a 20V Makita battery, and even though the module’s cut sheet says 12V (with the website claiming 27V max), it handles the 20V just fine. No issues with overheating or instability. I mounted the board inside the radio using hot glue. It’s been sitting out in the sun during use, and while the top of the radio gets warm, it doesn’t get hot. You can tell the module is inside doing its job, but it’s not stressed. The board itself feels like a higher-quality unit than many of the cheap Bluetooth modules out there. The PCB is clean, the build is solid, and it even comes with documentation—which is rare. It seems like buying a single unit results in better quality control. Honestly, if I had bought a two-pack, I’d half expect one to fail and just use the backup. But this one has been reliable from the start. Overall, I’d recommend this module if you’re upgrading an older stereo or building a basic portable Bluetooth system. There are much higher-end DACs out there for home audio, but for portable or jobsite use, this is a great solution that works well and sounds good.

Usé éste módulo para actualizar un amplificador Sony TA-A50 al hacer la interfase a una entrada que originalmente es destinada para un sintonizador de radio. Naturalmente la instalación requiere de soldadura y un vistazo al manual con los diagramas eléctricos para saber el lugar para instalar la conexión. Suena bien, cumple su función. Me agrada que el módulo tenga provisión para antena externa, pues instalar una ayudará a incrementar el rango de operación. Ampliamente recomendado.

This audio cable works perfectly for what I grabbed it for. I'm up stepping it to a 1/4 inch adapter to attach my bluetooth transceiver to my stereo. For this purpose, it's well suited and I did not get any 'cracks' 'pops' or 'sparks' when attaching it to my equipment. That said, I would prefer more of a 'smooth' surface rather than the slightly grabby 'tacky' surface that this has. Stereo equipment tends to collect dust and this style tends to attract more than the usual amount. Time will tell! That is neither here nor there though, as sound wise it sounds great and delivers the analog signal as good as one could expect.
