Well these are the new earphones, which I just bought recently and after using them almost 2weeks now, I could tell that these earphones produce great sound on all the bollywood tracks which I usually listen. I am not that expert as far as sound is concerned but when I compare it with my previous earphones they sound amazing. Actually my cousin recomend me these earphones and now I thanks him so much for the advice.
As per my experience I would recomend to all the listeners who listens music quite a lot but, are on tight budget, plus the build quality is also great, the only downfall I found that it does not have earpiece to recieve calls, but overall ots great.this time these are available on discount at amazon, so go and grab the deal.
