The stereo acoustic air-tube EMF radiation free headset avoids the use of electrical wires in the ear area. Therefore EMF is not produced by the air-tube and in addition the air tube is not served as antenna because it is not an electrical wire or a conductive material. In addition, the quality of sound is very high because of less interference in the audio signal. The headphones come with changeable earbuds for maximum comfort in S, M, and L. They sit securely and comfortably in the ear shape, even during vigorous exercise. Speakers Sensitivity 110±3Db SPL/3Mw/5cm at 1KHz Range of frequency 20 HZ—-20KHz Resistance 16Ohm ± 15% Rated Power 3mW Capacity 5mW Lead wire length 75cm – 100cm
