Dear Friends, I bought Blitzwolf BW ES2 and ES1 earphone headset from Banggood.com. After couple of days, ES1 graphene earphone sound quality got down. almost left stopped working and ES2 has got the noise which is very annoying. These brand is really looting with a high price and cheap quality product. I would suggest not to buy anything from BlitzWolf.
Thanks,
An Indian
