The first, the effect of damping:
1. The filtering: stop the outside sundry into cavity protection unit;
2. Headset tuning frequency division: according to the principle of sound frequency of different wavelengths, special materials and clearance by mesh, physical to filter out unwanted frequency sound waves.
(3) to reduce noise: the headphones sound pressure block, cutting burr, harmful wave headphones.
Second, the damping is chosen:
Low resistance used in high frequency, high resistance in the low frequency
1. The low-frequency unit selects the ,ZN-4700,ZN-100,00,ZN-14000,ZN-23500
2. Intermediate frequency unit selects ZN-1500,ZN-2200
High frequency unit selects ZN-330,ZN-680,ZN-1000
3.Damping from ZN-000-23500, the resistance coefficient increases in turn, means that the speaker voice burr, the high frequency wave absorption ability enhancement (you can take off the se846 damping directly to listen to, difference obvious), mainstream headphones to use more of them
ZN-330, ZN-680, ZN-1000, ZN-1500, ZN-2200, ZN-4700, (such as w4r with red, e5c in ZN-680, se310, ue tf10 used ZN-1500).
