If you want to stream music or listen to phone conversations through your car’s speakers, but your vehicle didn’t come with Bluetooth, an add-on Bluetooth kit is an inexpensive and effective solution. After testing dozens of models, we think the Besign BK01 Bluetooth Car Kit—which plugs into a car’s auxiliary-audio input (aux-in) jack—offers the best combination of sound quality, phone usability, and features. Below, we also include picks for vehicles that don’t have an aux-in jack, or for people who primarily use their phones for calls, rather than for music.
