First of all this is a very fantastic model in sony headphones.
The cost of this model normal price but the sound quality is far better another branded headphone.
Mostly this headphone are available in two colors Red and Blue.
A mono stereo headphone both are attached in two headphone connector. Sound quality just awesome Sony and other branded mobile company.
Im specially suggested this headphone is better for mobile.
This headphone also connected laptop and desktop but a single jack.
Other fancy things in headphone is its folded a small thing so u can carry also a pocket.
