  12. Ask Sedra/Smith or Razavi

  13. Roughly thinking wider is better?

  14. The frequency band human can hear 20Hz-20000Hz

  15. A really good headphone can reach to 5Hz-40000Hz

  16. But, the most important is “Filter Design”

  17. Please Ask Sedra/Smith or Razavi

  18. 3.Efficiency (感度)

  19. Measure : db/mw (or db SPL/V)

  20. Higher means that it’s easier to reach to the 聲壓.

  21. For walkman use,100db/mwor higher is better.

  22. Mine 127 db SPL/V = 108 db/mw

  23. 4. Impedance

  24. If the value is high, then it needs more power to drive.

  25. Generallyunder 100 Ω. Mine:17Ω “Year End Party Present”: (1).20Ω (2).32Ω

  35. Characteristic: “Warm”, and it performs well at the mid-band frequency response (Human Voice).

  36. 4. Beyerdynamic - Germany

  37. Characteristic: Put too much at the mid-band and high frequency band response.

  38. 5. Grado Labs - America 6. KOSS - America

  39. 7. $ony - Japan

  40. According to the “Headphone” board, - ”SONY的低價耳機幾乎cp值都很低”

  41. Generally speaking, a good headphone still need a good “source” to coordinate.

  42. MP3 Player?

  43. goods is good.

  44. Iriver, MPIO…

  45. Conclusion

  46. A good headphone can take you to the paradise. (Really Helps)

  47. I’ve asked the store owner to see the spec of the headphone,

  48. He says, “Whatever, it doesn’t help.” in Chinese is “好啦~反正也是看心酸的.”

  49. That means you need to use your ear to feel. Because ear is also a “Filter”.
