Stormopen StudioPro I — Over-Ear Hi-Res Audio Wireless Monitor Headphones

The Stormopen StudioPro I Over-Ear Hi-Res Audio Wireless Monitor Headphones are engineered for music producers, podcasters, mixing engineers, and audiophile listeners who require a faithful reproduction of the audio signal without the coloration, elevated bass, or compressed dynamic range of consumer-tuned headphones. Hi-Res Audio certification from the Japan Audio Society confirms that the 40 mm beryllium-vapor-deposited dynamic drivers reproduce frequencies up to 40 kHz, well beyond the 20 kHz upper limit of human hearing, a specification that reduces phase distortion and group delay within the audible band by ensuring the drivers are not approaching their resonance frequency at 20 kHz. The frequency response measures flat within plus or minus 3 dB from 20 Hz to 20 kHz, with the response curve verified against a B&K type 4128 HATS measurement microphone rather than the simplified coupler measurements used for consumer headphone specification. LDAC Bluetooth codec support enables 990 kbps wireless transmission, delivering 24-bit audio data at reduced lossy compression compared to SBC’s 345 kbps maximum. The 50 ohm driver impedance requires slightly more amplifier voltage swing than typical 32 ohm headphones, making the StudioPro I most suitable for use with dedicated DAC/amplifier sources or high-output smartphone headphone outputs. The 1,100 mAh battery delivers 30 hours of wireless Hi-Res Audio playback. Net weight is 295 g.
