I'm sorry if I am being obtuse. I'm in the very fortunate position of being able to buy a Poly. I love the Mojo. I've read many posts on here and also elsewhere online saying that Poly is somewhat difficult to set up and temperamental.Perhaps the relevance is that many of your posts, are written in the style of someone wanting the Poly owners, to persuade him not to buy a Poly.
On an online forum, it is impossible to hear clues about context, such as inflexion in the voice, so posters have just the bare text and emojis to rely on - and they can be ambiguous at times.
There are many Poly owners participating on this thread, who are glad to offer help and advice, but the style of your posts is confusing them as to how to reply.
On top of that I am very wary of devices that claim all sorts of improvement in sound quality with no basis in scientific fact. Unfortunately I am not particularly technically minded so cannot ascertain the veracity of claims for myself. Apologies again if I am being annoying.
