First lets talk abhout sound quality its not good at all, high quality sounds start to cracle and this headset said it has 'extraaaaaaaaa powerful bass' what exactly written on the box literally this headset has zero bass just flat sound, don't get me wrong it has some bass to it but that type of bass also given by Rs. 50 earphones, these headset start to vibrate like hell on full volume some people said on review you can get best bass on full volume but by doing that your partner can also experience the music , cheap plastic used seems like it will get broken just in one fall. Yes it has some good points too, it has good Bluetooth range. If that is the reason to buy it. No correct indicator for its battery. My earphones are much better then this. If you want... Their name is QKZ Just search for them.
