DESCRIPTION

- Lightweight open-air headphones are comfortable to wear, even for extended periods; also allows you to hear ambient sound.

- Ferrite magnets for high energy in a modest size; help produce ample sound output-100 dB sensitivity.
- PET diaphragms ensure high rigidity for minimum distortion; low mass for high-frequency response all the way out to 20,000 Hz.
- Sony Acoustic Turbo Circuit for high efficiency; gets high sonic output from your portable stereo; extends bass response.
- Single-sided cord minimizes headphone cord tangles and nuisance.
- Sony UniMatch plug with fixed mini plug for portable use and phone plug for home use.
