Super bass effect
A huge sound effect and equalizer
Automatic video song convertor build in (So High regulation playback)
Playback time audio 10hours + video 5 hours + non stop
This is sony's product so don't compare with others brand.Because the sony is the only brand of sound equipment which provide perfect bass (Even the Apple can not provide perfect bass,Apple provides more treble)
It's sound quality and bass system is 100% better than any apple device.You can tested before buying.It's my favorite device but i need urgent money thats why i will sell that.
With player,headphone and cable
