Panasonic is very popular and nearly worldwide acceptable company which deals in the electronic goods and appliances. I using this earphone of panasonic from very long period.
This earphone is very good and have very good quality of sound. This can make any song good. The best thing which I realise about this in a situation when you full the volume of your song. No audio will came outside of this. So the person sat nearby you will never gets disturbs just because of you. If you have this earphone with you that cleary means you are badly addicted to the music and you know the quality of eaephones. I don’t know too much about brass and other terms related to music but I know this provides a very clear ringing to us.
There are some disadvantages with this earphone is that their is no mic is persent so that means you can not talk to any person by using this earphone which is very big problem with this earphone.
I finally say go for it this is very good earphone.
