1, the number of earphone speakers is different.

The single power ring has only one horn, and the dual power ring has two horns.

2. The difference between the sound quality of moving-coil headphones and single-coil headphones.

Using different materials to make the high and low frequency units enter the dual dynamic loop will make the headphones perform well at all three frequencies. The concrete performance is dynamic analysis. Although it is not as good as moving iron, it is a great progress for single performance.

So in general, the hardness of multi-power is better than that of single power. However, in a certain frequency band, there will also be problems such as mutation, stiffness, unnatural and turbidity.

The difference between moving iron and moving earphone;

1, the sound insulation effect of moving iron is better than that of moving iron. Because the moving coil unit occupies a large area, it needs more space and air to participate in the vibration during the sound production process, and it cannot effectively control the sound leakage.

2. Moving the iron block can effectively reduce the ear area and place a deeper ear canal. (Almost all moving-coil earphones have air holes, but there are few air holes on the moving-coil iron ear. Because the geometric structure of the ear canal is similar to a circle, which is much simpler than the auricle, the soft silicone sleeve has better sound insulation and leakage prevention effect than the traditional earphone.

3. The frequency response curve of the moving iron earphone is relatively stable.

4. The advantage of moving coil is medium and high frequency. It has better analytical ability, which is why many moving iron headphones are suitable for poisonous female voices.
