Stormopen AirDrift I — Over-Ear Active Noise Cancelling Wireless Headphones

The Stormopen AirDrift I Over-Ear Active Noise Cancelling Wireless Headphones deliver professional-grade silence in a consumer-accessible package engineered for commuters, open-plan workers, and anyone who demands acoustic isolation without compromise. The ANC system uses dual feed-forward microphones mounted externally on each earcup, sampling ambient noise at 48 kHz and generating an inverse waveform through the 40 mm dynamic drivers within 0.3 milliseconds, achieving an average attenuation of 28 dB across the 20 Hz to 1,000 Hz range most disruptive to concentration and speech comprehension. The 40 mm drivers are wound with copper-clad aluminum voice coils suspended in a neodymium magnetic flux density of 1.2 Tesla, producing a frequency response of 20 Hz to 20 kHz with a sensitivity of 108 dB SPL per milliwatt. Bluetooth 5.3 connectivity supports the SBC and AAC codecs for universal compatibility across Android and iOS devices, with a connection range of 10 meters in open environments. The 800 mAh lithium-ion battery delivers 25 hours of wireless playback at moderate volume with ANC active, extendable to 35 hours with ANC off. A 10-minute quick charge via USB-C provides 3 hours of playback. The memory foam earpads are covered in protein leather at 1.2 mm thickness and compress to 50 percent under standard ear pressure for a passive seal that supplements electronic noise cancellation. Foldable hinges collapse the headphones to fit in the included hard shell carrying case. Net weight is 248 g.
