Because the headphone unit is relatively sensitive to dirt, its mesh cover has become the main focus of protection. It should be kept clean and avoid excessive contact with dust.Do not wipe the earphones with alcohol, thinner, or other solvents; 2. The cable of the headphones is quite delicate, so during use, try to avoid pulling, pressing heavily, or any other form of physical damage.Any headphones are quite fragile and cannot withstand frequent drops. What's even worse than a drop is that after falling from a height, the headphones don't hit the ground directly but are caught by something and hang in mid-air. At that moment of being caught, the damage to the headphone cable is significant, so you must try to avoid this situation 3. Try not to play CS games immediately after buying new headphones.Because the various sound effects in CS can be quite stimulating for new headphones whose diaphragms are still relatively tight.So it's advisable to start with soothing music for proper acclimatization, and then use normally after it gradually enters a state of readiness. 4. To ensure the best performance of the headphones, please wear them correctly with L for the left ear and R for the right ear. After receiving the headphones, do not play them at high volume as they are brand new and the speaker unit has not been well broken in. When first using them at high volume, it can damage the speaker! Headphone Purchase Information: 1.
