Bests & Worsts Reviews from Amazon

I have an Echo 1st Gen and it is way better than the Echo 2nd Gen I just received. Neither are worth a bleep for music. The 2nd Gen has terrible sound! Shame on Amazon for releasing such a piece of garbage. I’m returning it. Edited to Add: Another reviewer said s/he got a firmware update to version 592452420 and now their Echo 2nd Gen sounds great. I called and talked to Amazon Customer Service and verified I had the latest firmware, which I do, the one listed above. Perhaps it helped a tiny bit, but the sound from the 2nd Gen is still horrible. Anything over volume 3 and you get a tinny high pitched almost static type of sound and the base just sucks. This device is NO GOOD for music at all, even with the latest firmware. Face facts, firmware can only fix a few minor issues. If the hardware (speakers) are garbage then the sound will be garbage. No firmware is going to fix this issue. Amazon released a subpar device and they don't seem to care. I'm tired of testing it and trying to make it acceptable, I just called Amazon and initiated the return of this garbage. I like Amazon and it's services, but I won't buy anymore of their cheaply made garbage devices.
