Recently, my friend bought a smartphone, Sony Xperia L. There are various things provided by Sony e.g. Walkman, CyberShot, etc. which are embedded in this phone. When I listened to the music, I came to know that the headset provided is one with 3.5 jack. I had Sony Walkman back in the days, with those heavy headsets, which gave a fantastic quality sound. I think, the hardware has caused the sound quality to hamper, what is your opinion?
