I’ve been using this in my car to listen to music and podcasts from my phone for the past year. Sound quality is virtually identical to what I got plugging into the headphone jack (when I had one), plus now I have physical buttons for pause, play, forward and back, which is *really* nice for driving!
Occasionally the connection doesn’t quite work right and I get very crunchy audio, but when that happens I’m able to just turn off the phone’s bluetooth and turn it back on, and when they re-pair the sound is back to normal.
The one thing that bothers me about it is that the battery warning sound (bleeping once a minute) doesn’t start until there’s only about 10 minutes’ worth of battery left, which always seems to happen 5 minutes into a 30-minute drive.
