I have bought Philips, Altec Lansing, Sony etc. But none of them satisfied me. So I purchased Panasonic HNJ300. It cost me around Rs 1500. It was far better than previous brands and I was happy with it until.
This is the best earphone.
The wire length is 1.2m and is good. Other technical features are 16ohm impedance, 106dB sensitivity, 6 to 23000 Hz sensitivity. Another disappointing this is that it does not provide a mice and remote.
