When you place it on the floor and watch a movie, you will receive good sound (for a device costing between $10,000 and $12,000, do not compare with Hi-End). Three devices cannot be connected if two devices are connected simultaneously; one of the connected devices must be unplugged. If brand or aesthetics are not priorities, there are better solutions available on the market for this price. I didn't use it for calls, so I won't comment on the apparent presence of a built-in microphone.
