Adaptive Noise Cancellation up to 52dB

These headphones use adaptive active noise cancellation that automatically adjusts to environmental sound, reducing noise by up to 52dB. The system targets airplane engines, subway rumble and office chatter so you hear music, movies or calls without distraction. A transparent mode lets ambient sound in for announcements or conversations without removing the headset.

140-Hour Battery and Wired Fallback

A 1000mAh battery delivers up to 140 hours of playback or talk time on a single charge. When the battery runs low, the included 3.5mm audio cable enables wired listening so the session continues without waiting for a recharge. Bluetooth 5.4 provides the wireless link and supports multi-point connectivity for two devices at once.

Six EQ Modes and 40mm Drivers

Dual 40mm dynamic drivers are paired with six selectable EQ presets covering balanced, bass-boosted and mid-high enhancement profiles. Listeners who want a single fixed sound signature or who require a dedicated companion app for custom EQ will not find those options here. Check that your source device supports Bluetooth 5.4 for full wireless functionality.
