Stormopen NeckArc III — Around-Neck Retractable Cable Neckband Wireless Headphones

The Stormopen NeckArc III Around-Neck Retractable Cable Neckband Wireless Headphones solve the persistent cable management problem of conventional neckband designs by integrating a spring-loaded retractable cable mechanism into each neckband arm, allowing the earbud cable to extend from a minimum 5 cm storage length to a maximum 25 cm user-adjusted length and retract automatically to the stored position by a single button press at the neckband shoulder. The retractable mechanism uses a flat cable spool with a constant-force clock spring rated for 5,000 retraction cycles, storing a 22 cm cable loop in a 28 mm diameter drum housing recessed into each neckband arm. The cable itself is a 0.8 mm diameter four-conductor configuration — two audio channels plus ground plus common — wrapped in a braided stainless steel mesh overcoat at 0.1 mm braid wire diameter, providing a cable pull strength of 25 N before conductor separation that is 80 percent higher than the 14 N pull strength of standard PVC-jacketed earbud cables. The 12 mm dynamic drivers deliver a balanced response from 20 Hz to 20 kHz with 105 dB SPL per milliwatt sensitivity. The neckband body is constructed from reinforced ABS with a rubberized matte texture providing grip during sports use. The 1,000 mAh battery delivers 32 hours of wireless playback. USB-C fast charging provides 5 hours of runtime from a 15-minute charge. IPX5 water resistance. Net weight is 58 g.
