I had many headphone,including earphones with high configuration from branded company like JBL Sony etc.Even once gone through the confirmation and quality assurance from Pure sound I decided to have one to check claim of seller.
Started from low EU pure calm ,black ,an adjustable hearing protector.This is different type setting ,normally i had not seen at least I do not had.
But coming on reception quality ,yes really it's a. Challenging quality.Very difficult to realise why did not I find on any online shops .
Really I found it very competitive with any brands I am using since long time.I also seen one best headphone with good cost,hope I will buy it shortly .
