It is not possible to use the left earpiece separately, since the lead is right. Lack of USB C, you have to carry a bunch of wires. And so I would go with one memory and it would not be bad. Has pros: The sound is not bad, in the subway you can comfortably listen to music and watch videos. I do not recommend buying. You can gift someone you don't like. Its cons: After 2 months of performance: the battery on the left ear runs out quickly. The case holds the battery charge, it holds less than 10 hours.
