Performance is average.I were purchased it from Amazon.in for 899 rupees, ( listed for 2999 rupees and 70% off, but I were search in other e-commerce site it was listed between 600-940rupees.) There are no Mic in this headphone.Signature bass effect of JBL is very good, but it is applied for all songs and it not a good thing.If you used to listen heavy bass songs ( low frequency songs) then it is good for you but if you will listen vocals and melodies then you will feel that there are some unnecessary bass effects.Customer Services-I were used this product, after 5 month of using left speaker of my headphone was not ringing. I were search service centers of JBL, but there are no service centers are available in my city ( also around my city) .
