I purchased a 3 pack of the new Echo to get the $50.00 discount special. I had read other reviews where folks weren't happy with the sound quality of the speaker during music playback. I must admit that after I set up the first unit and played some music I would tend to agree. Flat base and a bit washed out over all. But Wait!! There's good news. As I set up the second and third Echos the first unit that had been set up for 10 minutes or so said, "I'm updating, I'll be available shortly". One by one each speaker received an update from Amazon and I have no idea how but after updating they sound "AMAZING" Full, rich base, excellent vocals and overall sounds as good as my JBL or UE Boom. If you are thinking of getting these but were afraid after reading the not so great sound quality reviews, go ahead. You will be more than pleased after receiving the updated software. AAAAA+++++ and the "Play Everywhere" effect sounds amazing.
