Phillips is a famous top selling company of sound system. But you will be bery surprised to know that this headset is a very cheap quality product from Phillips. In the description of product all the specifications are very attractive like the hd sound clarity, bass setting, portable and blah blah. But actually it is a local market product which is sold on Street at a very low price. Its been just 20 days I am using this headset and one side has stopped working and even before that the sound quality was average with zero bass. There is no setting for bass only there is a volume button given. And the headset is very loose it is not portable as the material quality is cheap. So be careful while buying Phillip products and I would recommend skullcandy or a jbl product’s over this headset.
