Only came, not yet included. Installation is very neat. Packed first-in a sealed antistatic bag, then-in a pup, then-in a cardboard box. It came in perfect condition. The knob for the volume control is included.
Came quickly. Logic is so:
1. in Bluetooth mode does not cut out the sound in silence. As a result, there is always a background. At 0 volume, in the absence of a phone, on pauses. At 50 volume, the background is noticeably louder than at 0 or 100 (it is in Bluetooth, the linear background grows, khm, linearly). The size of the background is difficult to determine, because while hooked the Speakers 2x3 W from the toy, to the normal will get later, there and add, but shorter to keep this thing turned on the house around the clock will not come out.
2. the line input is plugged into the jack. But when you restart the power, the Bluetooth turns on again, you need to overdo Jack.
Events comment in Chinese, but quietly against the background of the signal, it's good. Not unplugged sockets vol +-work as everywhere (short-switch track, long-volume). TF did not check and do not plan.
