【Sound Like a Pro】- A premium audio quality is essential to achieve greater performance. Installed with apt-X technology, wireless earbuds provide powerful, low-bit rate transmission and scalability for free lossless audio. Nothing is more important than always enjoying music through the toughest workout.
【Touch Control & Volume Control】- Together with smart touch sensors, wireless earbuds can get ultimate control (Volume Control Available) without using the phone and largely prevent the discomfort like the physical button (90% of Wireless Earbuds: Volume Control Unavailable). With ergonomics and redesign, wireless earbuds can fit and stay secured in the ear canal even with intense movement.
