I bought my iPhone to listen in the car. I listen rather podcast (people talking) that music. I was curious if it would be strong enough. So I thought if I can still not enough to add a second (they makes). But this little pregnant widely enough, and I'm surprised even music in my car bruitant (diesel) and really strong with a big beautiful sound.
Positives
Strong, good sound.
Super small, plus it closes even smaller.
Works with all music players.
Battery holds long and sound and strong same when it is not connected.
Negatives
It's clear the stereo effect is lost (perhaps better with 2 chained)
The USB cable is very short.
We must think about the etiendre after use, if not the battery runs out.
But overall it is SUPER!
