Popularization of Earphone Knowledge
High resistance headphones can be simply understood as high sensitivity, low current headphones, and the whole headphone knife is placed in the system.
The impedance of sound at different frequencies is different. The higher the negative impedance of headphones (electrical appliances), the higher the internal impedance of the receiving source (power supply).
The sound is low and the quality is good. 250 ohms or more is high resistance. Between 100-200 Euros
M belongs to medium impedance headphones.
1. Low resistance is difficult to push and sound, high resistance is difficult to push and sound. Low resistance headphones eat current, resulting in increased distortion and control.
Weakening of force and other consequences. The high voltage of high resistance headphones has no such negative effect, but low-end devices (especially
It's a portable sound source.) The high resistance headphones can't reach the required pressure swing, so the sound pressure is not enough. In short, as long as the sound pressure is enough.
Sufficient (that is, enough power) should be selected as high resistance headphones as possible.
2. Low resistance is easy to make good sound (note that it is easy to make good sound, not easy to push), but it can not be pushed to the most.
OK. High resistance is prone to bad sound in low-end equipment, but the sound in top-level equipment is undoubtedly the best. So low resistance.
Low impedance for end equipment and high impedance for high-end equipment can not only depend on output power.
