Medium sound quality, card reading function should be noted
Most satisfied
Excellent performance in the same speaker, strong combination ability, and card reading.
Most dissatisfied
The ability of identification card is poor. I got two types of m15, one of which can recognize 2g and 4g cards, and the other one is intelligent identification of 2g cards in my hand: throw away the card factor, the same m15, and buyers should pay attention to this weakness when buying.
summary
The sound quality is good. The card reading function must carefully check the support for different cards
