Application:

1. Professional and tactical scenarios: military and police communications (spring wire connects tactical headset and throat shock microphone, suitable for violent movements such as crawling and running, Kevlar filling prevents the wire from being hooked by equipment)

2. Internet cafe/office headset, sports headset

Feature:

1. Elastic retractable structure: spiral spring shape (using a spiral winding design similar to that of telephone wires, the stretching length can reach 2-4 times the original length, greatly reducing the risk of winding, and adapting to the stretching needs during head movement (such as running, tactical movements))

2. Tensile reinforcement: Kevlar bulletproof fiber is often filled inside to provide ultra-high tensile strength and withstand frequent pulling; wear-resistant TPU or PU is wrapped outside to take into account flexibility and durability

3. Environmental adaptability: sweat-proof, waterproof, and temperature-resistant

4. Electrical and signal performance: low-loss transmission, anti-interference design
