Selection of headphones considerations.

1. Transfer mode

Selection of headphones, packing of headphones, or instructions on which performance metrics to pay attention to Because low-quality headphones are frequently made by tiny facilities, their performance metrics are labeled haphazardly, and some are overstated. Headphones must normally have a minimum frequency range of 20-20kHz, more than 100mW of power, less than or significantly less than 0.5% harmonic distortion, and so on. You should not buy if you cannot meet the above standards. It is also advised not to buy if the performance of the manual is mentioned too highly on the product.

2. The quality of product workmanship

The more authentic headphones produced by large manufacturers use is usually engineering plastic, so the appearance is very smooth, but also a certain amount of stress and toughness. This headset does not have a sense of hardness, workmanship is also relatively fine, and feels excellent, not to mention the use of poor quality plastic roughness. Also, the lead wire diameter of the headset is relatively thick, which can ensure stable transmission, the touch of the line is soft and hard; the plug is very clean and sharp, will not leave burrs, smooth and uniform plating. If the above conditions do not match the best not to buy.

3. The expensive does not necessarily suit you

Many users think that as long as you buy a more expensive headphone will get better sound quality. However, there are some headphones with high impedance, high impedance headphones can certainly better control the sound, but this requires more output power support. The MP3 player itself has limited output power, and it is impossible to drive high-impedance headphones well. MP3 playback in the market at present, more common is 5mW 5mW or so output power, in this output power is best to use the impedance of the headphones below 50 ohms. Therefore, it is best to look at the technical parameters of the headphones and MP3 players before upgrading, or find out after buying back mismatch will be very troublesome.
