I setup the speaker with the Yamaha MusicCast app, which worked fine.

Absolutely love the Musiccast

Streaming to both my wired Yamaha MusicCast compatible receiver and these wireless units produced an echo due to a half second lag

MusicCast is great!

But I am very satisfied with the WX-010’s performance and ease of use as well as with the app.

but I am out of the return window and threw away the packaging as they worked at first.

These are just initial impressions , won't comment on Musiccast but can't complain, everything works as it should

Airplay works as it should and the speaker is seen on iOS devices as a selectable audio destination.
