The worst for me about the sound quality is a low hum in the background, normal for radio, but annoying in music or phones conversations.

In fact, it adds unbearable echo and annoying noise.

The sound quality is perfect, the connecting noise can be loud and annoying at first, but you get use to it - it's like ringing bells

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

The only thing is that the sound quality was pretty static-y when I put my phone in the back seat pocket, so I think you need it up in the glove compartment or front cup holder for the sound to be really

This is almost perfect but it is a little static-y

Sometimes it’s fine, sometimes it still sounds static-y despite being on the best channel available to me

This product does exactly what it claims to, my only issue is that the audio seems to be extremely static-y, I'm not sure if anyone else has experienced this.
