The Denali D90ANR is an extremely lightweight headset that offers exceptional performance and outstanding comfort. The Denali is engineered to fit unlike any other aviation headset, providing excellent passive and active noise attenuation, a secure and comfortable fit and extremely reliable performance.

Lightweight Comfort
At less than 14 ounces, this headset is the lightest ANR model available. Denali’s ComLeather™ ear seals help abate noise and offer a comfortable fit. The sleek ear domes stay securely in place, reducing side force.

Dual Inputs
This top-of-the-line model includes dual inputs that support cell phone and Aux connections for communication and entertainment. Automatic muting ensures that all incoming transmissions are instantly heard.

Extended Battery Life
The D90ANR uses two always available AA-size batteries for up to 50 hours of continuous ANR use.

Sure Power System™ (SPS)
This ANR model also has SPS – a digital power management circuit. The SPS conserves battery life by shutting off the ANR circuit when not in use. Full passive performance is maintained when the ANR circuit is off.

Noise Reduction
ANR model achieves additional 18-20dB at certain key low frequencies.

No Risk Warranty
Satisfaction guaranteed from ear to ear. Three year warranty.
