Hello guys my personal experience with I bal pulse BT-4 was not so good or even I say its worst then the bad.i bought it from world class online site flipkart for Rs 950 and initially I thought its good but after 2 week I realize I made a big mistake by investing my money in wrong product.
The main default in this headphone is its battery back up which is not up to the mark or I say it take around 3hour to get full charge but after that iylt run last for 4hour which is very or it doesn’t work in both platform ( cable and bluetooth) which also a major problem I mean if it work in both cable and wireless then we turn it into wire after used of all battery.The one more problem with that is its heating while listening songs which tends me in threat wheather its not blow up while listening songs.I ball should need to work on it and launch a better option instead.
As per my experience with that I suggest you to not invest there money in this kinds of headphone which is just like next to scrap.
