BESIGN BK01 Bluetooth Car Kit, Wireless Receiver for Handsfree Talking and Music Streaming with Ground Loop Noise Isolator for Car with Aux Port

Update 5/16/20This has turned out to be a pretty cool device. It works as intended and passes the audio signal it receives just fine. In my first review, I complained about the audio quality. I recently acquired a new phone and it turns out the poor audio quality I experienced was due to my old phone. My new phone streams to it just fine and it sounds great playing through my car audio system. Making phone calls through the BK01 also works well. Having yet paired my phone to the car, I took recent calls through the BK01. I could converse with callers just fine. This is the bluetooth device I've been looking for. I'm glad I stuck with it and parted ways with a crappy LG phone. The audio is still loud and it doesn't weaken the bass. It all depends on what is connected to it.(original)I bought this as an inexpensive alternative to replacing the radio in my car. It functions as intended but with issues. This review is after using it for about three months.ProsInitial pairing is simple and quick. Connecting after the car starts is also quick.It is LOUD and I love it. I don't need to turn the car volume up high to hear what it streams and the bass frequencies through it are amazing. I've had to turn the bass down in my car.If the adapter is not paired/used, it powers off as to not be an unnecessary power drain.I enjoy the button controls. Helps me avoid handling my phone while driving and I can keep my eyes on the road.The main button is lit but not obnoxiously bright; it isn't a distraction during night driving.ConsThe back button randomly works. It's hard to tell if it's due to the adapter or app currently playing.While it is loud, the sound quality aside from the bass frequencies(which are great) is moderate to terrible. I'll explain. The quality of listening to podcasts and audio books is perfectly fine. Listening to music is not fine. This 4.1 adapter can't handle the dynamic ranges of any song. There is distortion in every song I listen to, no matter the app playing on my connected phone. I've tolerated this thus far but I will seek an upgrade in the near future.I can't judge the Mic or call quality because I don't use that function.

First off I didn't get this for free, like some others. I paid the full $24,99Didn't want to go with the FM transmitters since I did not want to deal with FM tuning and noise, hiss etc and because I have an aux+charger in the arm rest. IF you don't have aux input you cannot use this thing.Recently bought a used Subaru Outback 2010 with no BT. But it did have an aux and charger in the arm rest. I was looking at a lot of other models that are cheaper, more expensive. Bought this because one of the reoccurring complaints with many BT car kits in the Amazon and Youtube reviews is the noise that comes from the car motor and the need for a ground loop isolator. I looked at the loop isolators separately and they cost around $5-$7 so assuming I would have the same problem many others did I chose this item which had the best value as a combo that also had BT version 4.1. I just wanted to assume 4.1 would be better at handling 2 phones simultaneously connected to the unit.I will not give a detailed explanation on how to install since it is pretty straight forward but here are some notes from last weekend:1- Connects to 2 phones with ease and delivers calls from both and muting music if on one phone to allow other phone to ring through the BT. I needed this since I have a company phone and personal2- Call quality is good. Pestered my wife who swears she could hear me perfectly on my many trial calls. It was clear with both one and 2 phones connected.3- Music quality is GREAT. No motor sound even when music paused in my 2010 Outback.4- There were some complaints about other units not having an on/off button. Long press the phone icon and this thing turns off and long press again it turns on.5- All 12v ports on my car turn off when car is off. Upon first entry into my car and turning the ignition and waiting for the engine lights to turn off, the phone pairs automatically. But further turning on ignition to start the car turns off the Bluetooth unit. I was worried I would have to pull the charger out and place it back to restart every time I entered the car. No need. Just press the blue phone icon on the unit and it turns on and pairs. So essentially this means every time I drive I have to turn the unit on, but I don't have to pull it off the charger.6- My Moto X has a hands free "Hello Google" option that I turned on. Now I can tell the car to "navigate me to the nearest Dairy Queen". This works without long pressing the FW button which also turns this function (Siri I guess for iphones) on but sometimes it doesn't work without pressing and sometimes it doesn't work at all. I think this is more due to my phone being old, rather than the function on the unit.7- All the FF and RW buttons etc work fine.8- Also skyped parents and no complaints there either.9- Pretty long cables. After where aux and charger ends Y split on the cable the aux end (may be the charger end though) is even longer. I set the magnet a little higher than my knee level on the dash board and have more than half the cables in the arm rest unused. Be careful with some units that have very short cables.Apart from that a BT car unit is a pretty basic thing but with an important function, for me at least. I go on long business trips and sometimes drive for 10-15 hours and I need all of these to work. It looks like it will do the job. Only been 2-3 days so I don't know if the thing will last. We'll see. Will update if it craps out on me.

This is a great and inexpensive BT adapter fro your car that does not have BT streaming function. The noise suppression module is awesome and eliminates the spark plug buzz. They even include a cigarette lighter power adapter. It connects to the phone very quickly after having been paired and the sound quality is excellent for the automotive listening. Great device and simple to set up and use.
