Stormopen NeckArc I — Around-Neck Bluetooth Neckband Wireless Headphones

The Stormopen NeckArc I Around-Neck Bluetooth Neckband Wireless Headphones offer a comfortable, hands-free audio solution for users who prefer the neckband wearing style for extended listening sessions, phone calls, and light physical activity without the full-size headphone commitment. The neckband body is injection-molded from a flexible thermoplastic elastomer core with a 63 Shore A durometer that bends freely under manual pressure but returns to its formed arc shape when released, conforming to a natural neck curvature range from 280 mm to 350 mm nape circumference without requiring size adjustment. The neckband houses the 1,500 mAh battery in the rear section, with the Bluetooth 5.0 audio module and control board distributed in the left side section to balance weight evenly across the neckband arc. The 1,500 mAh capacity delivers 40 hours of wireless playback at 70 dB output — the highest battery runtime in the Stormopen portable headphone portfolio — leveraging the larger physical volume of the neckband housing compared to earcup-mounted batteries. Two 10 mm dynamic drivers are housed in the earbud tips at each end of the neckband cable, tuned for a balanced response from 20 Hz to 20 kHz with sensitivity of 104 dB SPL per milliwatt at 16 ohm impedance. Magnetic earbud tips snap together when not in use, automatically pausing playback through a hall-effect sensor. IPX4 splash resistance. Net weight is 52 g.
