5. What material is the JT7 headphone shell made of, and what is the wearing experience?

Except for the stainless steel headband, all other parts of the JT7 are plastic structures. The JT7 adopts a lightweight design, with an overall weight of about 318g (excluding headphone cable), making it light and comfortable to wear.

Will the JT7’s plastic structure be easily damaged? The JT7 uses high-strength plastic materials, and all plastic structural components undergo high-intensity fatigue and destructive testing. Each batch of material assembled into finished products undergoes over 5000 expansion tests, extreme expansion tests, over 10,000 torsion tests, extreme torsion tests, over 5000 swing tests, extreme swing tests, over 5,000 bending tests, structural tension hanging test over 5kg, 1.7m drop test, and 12-hour vibration test. Therefore, it will not be damaged under normal use.
