BESIGNBesign BK01 Bluetooth 4.1 Car Kit Hands-Free Wireless Talking & Music Streaming Receiver with Dual Port USB Car Charger and Ground Loop Noise Isolator for Car with 3.5mm AUX Input Port

Clearly and strong

I recently bought this for my Lexus is250 2009 since it doesn't come with Bluetooth for music. When I first tried it, it was horrible since there would be so much noise and please DO NOT USE the ISOLATOR it comes with, it is horrible it will just ruin the quality so you can have no noise but the music will have horrible quality. Without the isolator you get good quality sound but a lot of noise, what fixed this issue for me was instead of giving the product power through the cigarette USB port, I instead started giving it power via a power bank and boom that solved both issues. Perfect quality sound same as using an AUX cable and no noise whatsoever with Bluetooth capabilities (and again do NOT use the ISOLATOR it comes with). The only small hassle is to unplug the powerbank and plug it in everytime I exit the car and enter it but I believe it's worth it, + with the low amount of power it takes I have yet to charge my power bank. Just remember to take the powerbank out of your car if you park your car outside in daytime cause then it's a safety hazard else your all good. With the powerbank solution it's a 9/10 but without the powerbank solution it is a 2/10.

Good quality, easy to fix and surprisingly amazing sound quality when streaming music.

BK01 is a great product that provides a good sound quality.

This product works phenomenally. Easy set up and with the aux port in the glove box it tucks away nicely and auto connects everytime you get in your car.Zero fuss, strong Bluetooth connection and premium audio quality.Buy this and you will not be disappointed.

I think this is the perfect solution for installing Bluetooth on a car that doesn't have it, as long as you don't mind the wired connections of the receiver.My favorite thing: it disconnects and turns off automatically when the car is turned off! Other devices I tried before remain on when you turn off the car, which would cause my phone to remain connected even when in my house due to the large range, and would often connect without warning while in my house without my knowing and was a general nuisance. Also not sure about battery drain on the car if the car sat a long period of time. This device fixes those problems!Other positives:-long cables that facilitate any car setup you need, allowing me to use power from my rear power outlet and leaving the front seat outlet available.-The grounding device ensures there isn't any annoying static hissing noise through the speakers when it's not playing audio.-Mic works fine for calls and people have reported they can hear me fine while I'm driving. The connection is also quick and my phone automatically pairs with it when I start the car, unlike other devices I've tried that promised immediately connection but required a manual connection almost every time.-I'm a big music guy, not a full audiophile, but I can't detect any loss of quality compared to other Bluetooth connections.-buttons work well. Sticker mount included so you can stick the control device wherever you need.Only negative may be that the extra grounding dongle and excess cable length may be an issue if you are working with a very small space. It also requires cable connections, and I believe it also requires a constant power source. You may prefer the clean look of a dongle that plugs directly in the aux port and would need to be charged occasionally. I want to just be able to hop in the car and start playing, which this does perfectly, I never have to worry about the charging and I've hidden the excess cable.I had to scroll through several "top rated" or "best selling" devices to find this one, but I genuinely think it's way better than the other options on Amazon and it's well worth the extra ten bucks or so. It's completely transparent in how it operates, and it's as if the car just came from the factory with Bluetooth.

great device. sound very clearthe grounding help to eliminate the noise .

Funktioniert super! Freisprech und Bluetooth.Meine Anlage im Volvo ist super, jetzt auch mit Spotify!

Installé dans ma voiture (BMW série 3 Touring) depuis une semaine, il fonctionne parfaitement avec un son excellent et une installation hyper simple et rapide. Rien à redire. N’hésitez pas.
