Stormopen NeckArc II — Around-Neck IPX6 Neckband Wireless Sport Headphones

The Stormopen NeckArc II Around-Neck IPX6 Neckband Wireless Sport Headphones extend the NeckArc format to demanding outdoor sports use with an IPX6 waterproofing rating that withstands sustained heavy rain, water splashing from multiple directions, and post-workout rinse cleaning under running water, making these headphones genuinely suitable for open-water swimmers, rowers, and outdoor athletes training in all weather conditions. IPX6 certification under IEC 60529 requires the device to withstand water projected from a 12.5 mm nozzle at a flow rate of 100 liters per minute from any direction for 3 minutes at a distance of 2.5 meters without water ingress into the housing. Achieving IPX6 in a neckband form factor requires comprehensive sealing across four interfaces: the earbud cable entry points use overmolded single-piece construction that eliminates the seam interface entirely; the USB-C charging port uses a silicone flap seal rated for 500 cycles; the control button area uses a submersible membrane switch rated to 300 kPa water pressure; and the neckband rear battery compartment uses laser-welded TPU shell seams that resist hydraulic pressure equivalent to 0.5 meters of water head. The 12 mm dynamic drivers are tuned for high-energy sports listening with elevated bass and treble response to cut through high ambient noise during intense physical exertion. The 800 mAh battery delivers 25 hours. Net weight is 55 g.
