anybody who has owned sony jbl or sennheiser headphones earlier will be slightly disappointed the sound is considerably good but the bass sound clarity are different for different songs though ripped at exactly the same kbps 320 in my case the sound of instruments and vocals get mushy and mixed up the bluetooth in these headphones has a limited range its only constantly connected if you put yr phone on a holder when riding a bicycle or wrap it around your arm when jogging otherwise t
