This unit sounds really good, no background static or annoying voice that screams PAIRING, just a subtle beep

This product is good but somehow this technology is not very good at noise cancellation and while you can play your favorite music over the Frequency, you will still be hearing the background noise like a typical radio station scanning noise.

The replacement works perfectly fine without the background noise and connectivity problems

And you get this annoying background noise, which really bugs me

Charging is fast for phones sound is great and has no background noise calls come in

I first tried this in my '04 Toyota, but it exhibited too much background static like others noted.

No background noise or hum (during silence waiting for the music to play.)

The background static cancellation works too well

Horrible background static

The other person on the line will hear a lot of loud background noise

Buttons do not work as they supposed to do."Anker reached out to me and offered a replacement since my original unit was defective

He says it works as it should.

I just received my unit Saturday, and haven’t used the phone call feature as of yet, so unable to speak on that at this point

Work as it should.

Buttons, work as they should

It worked as it should and easily.

Ok it works as it says and better the sound on BT IS GOOD

Voice quality on phone calls is adequate but not as clear as on built in car bluetooth.

but I looked on YouTube and turns out if u find the right frequency it'll work as

So far this product works as it should, arrived on time, and good quality for the price

It works perfectly, with crisp audio, no problems, and no freaking Peaches by Justin Beiber, or Good 4 U by Olivia Rodrigo
