Just got this few hours back.At first I was pissed because the terreble was very high and shrill.But I played around with the equilizer a bit it seems working fine.The reverbing is good.So the only thing is you have to play with the equilizer a bit to get your sound.This earphone has noise cancellation but the bass in this earphone is not so strong while clarity of the sound is very good.Mic is very good with better call quality.I havent felt any negative aspect in my voice at caller side regarding my voice, volume and clarity.The major CON is that the jack is angular thats why I think it will not last for more than 3 months.
There are few things that you should know.
1.There is a slight distoration in very high volumes.
2.This didnt worked for me with my audio extender.But it did work fine while putting it in the port directly.
Lastly , it is a good product if you take the time to fiddle with the settings.
