At volume lots of background noise.

A lot of background noise

There is little to no background noise when the vehicle is running

High level of background noise at volume

Sound is clear, I do not hear background noise

Excellent FM transmission with no background noise

It streams my music impeccably but when I am talking to someone on the phone, even though I can hear them perfectly, they hear all of the background noise, specifically when I am driving on the freeway and it makes it impossible to talk to them without screaming so they can hear me.

With the other I heard a lot of static background noise, but with this one my music from my phone comes through my old car's stereo loud and clear.

I had to turn the stereo up extremely high to compensate, causing a background noise

So you can increase the volume on your device and on the transmitter as well as with your car stereo volume knob or button.

Had the older version which I liked as

Works as it should and AWESOME tech support!!!

Works as it should.

It's not perfect, but it's as close to perfect as I expect for the price range

Awesome quality, both in the hand as well as in the ears

great!I highly recommend this transmitter, I think you will love it, not much else to say except I would certainly buy again!

I recorded some mp3’s I’d ripped from CD’s onto a 16 GB micro SD card and a flash drive adapter to evaluate both options.
