Hello todat I purchase jbl c50 hi that is not a good product.
Item price is high, but not give us a good base not give us a high quality mic.
Its work between 20Hz to 20 kHZ that is not good for our health and ears.
In that price other company gives us a better product compare to that,
Like base sound jbl says he gives us a good base but equally its sound like a simple and normal,
Other thing is mic, that is also not good some time voice is not clear in mic ,
And that is not comfortably set in our ears alwasy when you put in ear phone they drop again and again.
His frequency is also is very high that is so harmfull for our ears
