The TRACK Air wireless earbuds feature noise-isolating functionality. They deliver clear sound and also enable phone calls in excellent voice quality. The extremely lightweight earbuds fit comfortably in the ear and can thus be worn over longer periods of time. One battery charge suffices for eight hours of operating time; when the earphones are placed in the charging box, this time can be extended for another 32 hours. The earbuds are available in black, white and pink.
