All ok! Sent quickly.Everything works qualitatively. Connect in. Sound is normal for mobile use both for listening to music and for answering and making calls. It came charged, for the day of inspection and did not discharge to the end. I recommend.
The package and view corresponds to the description. The parcel came in 24 days intact. Works in all modes perfectly, only in headphones a slight lag in sound. But literally minimal, so it's not critical. The thing for me is useful and necessary. Quality of materials, functionality, efficiency-all very well, based on the ratio of quality/price
Works as a receiver, and as a transmitter. In the car on charging catches great interference. Without charging the sound is clean. Connected to the tv and listened to it in the bluetooth headset! For the sake of that and took. Has a built-in battery for 7 hours of work (the time did not check, but the film for two hours withstood, the charge is still there.)
Order delivered quickly. As a receiver-works in mono mode, and as a transmitter-in stereo, I.E. In Bluetooth headphones will not be able to watch a movie from a TV or player with a connected audio transmitter in a stereo sound. Frequency characteristics are average. And vice versa: if you connect in Bluetooth, for example, to a smartphone, and in the transmitter to plug wired headphones in the TX mode, the sound will be stereo: only I do not see the point, (in all smarts) there is a better Bluetooth transmitter.
