Low latency for video and calls

Picture and sound stay in sync thanks to low latency performance, making them suitable for streaming and voice chat. The slant touch control area reduces accidental commands while adjusting playback or answering calls. Ten minutes of charging adds one hour of listening, and the case fully charges in about 1.5 hours.
