Delivery took less than 18 days to new mail. Packed, as always, fine. The sound quality is excellent, the power is enough, it came fully charged. Compared with the old version of A10: size bigger, more passive membrane for bass, HF bigger, mish a little less, LF deeper, put the USB C type, there is a separate input for the USB flash drive. Due to increased volume and increased distance between the speaker became more stereo effect, already clearly can be cured in which channel plays the tool. In general, the sound became more V-shaped slightly. Tried to connect in TWS A10 and A10 + mode but did not work out, but it would be a pity, it would be good. For the manufacturer I want to leave a wish-it's time to already equip the apt X column with codecs, the reinforcement part is perfectly refined, now it's time to add chips to increase the quality of wireless transmission.
