It is a chinese brand. I got this for Rs.650 .I been almost a year that I am using these earphines and I am very happy with it.!
Sound quality: sound is very clear. Bass is appropriate not made for bass lover but you looking for balanced sound quality.this is a must buy.
Microphone quality: I must it has the best mic I have ever used. It gives clear voice to the person on other side of the phone even when mic is not closer to the mouth.
Build quality: this the area where this product lacks.it is not very sturdy. it got cracks near mic.
All in all it is amazing product if u get it under Rs.650/-
