Still curious about the BESIGN BK01 Bluetooth Car Kit? Here are some answers you might find interesting:

🎶

What is the sound quality like when using the BESIGN BK01 for music streaming?

If you're considering the BESIGN BK01 for music streaming in your car, the sound quality is generally pretty good according to our research. While feedback is mixed in some areas, most people seem to find it a nice option for cars that don't already have Bluetooth. The manufacturer highlights that it streams music through your car's stereo via Bluetooth 5.0. This tech is supposed to improve efficiency and work with lots of devices. As for how the music sounds, most folks seem to appreciate the rich and clear audio. Plus, it has a built-in ground loop noise isolator to help cut down on any annoying background noise, which is a nice touch. However, there are some hiccups on the hands-free calling side, especially with [iPhones](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhones%26tag%3Dssw.ans.tx-1-20). Some users mention issues like lower call volume or a random loud beep when you play or pause. Simple fixes like toggling Bluetooth or reconnecting the device sometimes help, but these might be tied to firmware that can't be updated. In terms of just streaming music, though, people are generally happy with it. They like how quickly it pairs and how smooth the audio is. It can even connect to two devices at once, which is handy if you like switching audio sources. So, if your main focus is music streaming, the BK01 might be a reliable and affordable upgrade for your car. Just keep in mind those potential calling quirks if that's something you'll use a lot.

How does the BESIGN BK01 Bluetooth Car Kit handle ground loop noise?

The BESIGN BK01 Bluetooth Car Kit is pretty handy when it comes to dealing with ground loop noise. You know that annoying humming or hissing that can sneak into your car speakers? Well, the BK01 comes with a ground loop noise isolator to tackle that issue. From what we've found, this isolator does a good job of cutting down on static and unwanted noise, which often gets left behind by other Bluetooth gadgets. So, you can expect clearer sound when you're on a call or jamming to your playlist. Another cool thing about the BK01 is its design for convenience. It has this neat feature where it automatically powers on and connects to your phone's Bluetooth once you start your car, as long as it was connected before. Folks generally love not having to reconnect each time they drive. If your vehicle's 12V outlet turns off with the car, though, you might need a quick button press to get it going again. When using the BK01 for hands-free calls and music streaming, it generally performs well, according to our data. The noise isolator really helps keep the sound quality solid. Occasionally, you might have to adjust call volumes or reconnect your phone after starting the car, but these are usually simple fixes. Plus, the BK01 can hook up to multiple phones at the same time, which is great if you switch between work and personal devices or share a car with others. While it primarily helps improve sound in older vehicles without native Bluetooth, you might hit a minor glitch here or there. Still, for cutting down on ground loop noise and improving in-car audio, it seems like a solid pick.

Can the BESIGN BK01 connect to multiple phones simultaneously?

Yep, the BESIGN BK01 Bluetooth Car Kit can connect to multiple phones at once, so it's pretty handy if you're juggling a personal and work phone. The manufacturer says it’s made for hands-free calls and streaming music, perfect for cars that have a 3.5mm AUX port—awesome for older models without built-in Bluetooth. Our research shows that it's easy to set up. Just plug it into your car's aux input, and it turns on automatically when the car starts. People like how it seamlessly reconnects without any hassle every time you fire up the engine. The kit uses Bluetooth V5.0, which helps with a stable connection and doesn't drain your phone’s battery as much. But, heads up—some folks have mentioned noise interference on calls, even though it comes with a noise isolator. This issue seems to affect calls more than music, as sound quality for streaming is usually pretty good. One thing to watch out for is the cable situation. The long cables can be a bit of a pain to manage, especially in smaller cars, so you might need to get creative to keep things neat. If your car has a 3.5mm AUX input and you’re on the lookout for an affordable way to add Bluetooth, the BESIGN BK01 might be a good match. It's generally received good feedback, but just keep the possible call noise and cable management issues in mind.
