There earphones and good sound and signature.the bass is good but certainly its not overpowering but also it is more punchy of all the budget earphones.The bass kicks hard when we needed.
Sony has quality bass and sub bass that goes deeper than Panasonic.Sony puts much more emphasis in2-6KHz region and also comes with slightly more treble.
I will probably fail to distinguish between 192kbps and 320kbps
using there earphones.
if you a music junky just go for it.
