GoldUmbrella Unfortunately, a colleague, I was very disappointed the ears (for such little money!). And okay, if only in my MI8, but because the same lousy sound and Huawei Nova 3 and Samsung Galaxy Note 5. Not until you listen to all the great acoustics, clear sound, all frequencies in its place, in short, sonic orgasm! !! But as soon as the added bass, bit / drum, or electric guitar, begins a $ # @ * that the blood from the ears gushing fountain. Bottom line: I am looking for other TWS headphones and think where to sell these.
And about AptX codec, I realized that on 5 blutuz it does not matter, because radio channel width can transmit a much larger amount of data and without additional dances with a tambourine, so I did not find the lugs 5 blutuz and codec AptX.
