So how does the Beoplay A8 compare with Beolit 15?

Did some research on the brand, they are hard to find in the States. Very few reviews on the US Amazon, not that good, either. Someone mentioned a brand name Sonos. He said Sonos is much better than the A8. Sonos has hudreds of fantastic reviews. Many of these speakers are not found in local stores and thus hard to hear them yourselves. That' why I rely upon reviews of other users especially the informed like yourself.
