A lot of buzz has surrounded LightSPEED Aviation's newest ANR headset, the Zulu, introduced at AirVenture 2007, with the first sets shipping in September 2007. Featuring Bluetooth connectivity between the headset and your cellphone, MP3 player or other compatible devices, LightSPEED has integrated current (and convenient) technology with the headset's aviation-specific features. It's drawn a natural comparison with Bose's Headset X; however, at $850, it's priced at about $150 less than the Bose.
Music muting is the process that brings the volume of the music down when there's an overriding signal such as an ATC call or in-cockpit conversation. Testers had observed that when the voice signal was weak, it would not mute the music sufficiently (for instance, if you're monitoring ATIS 30 miles out). The threshold was lowered to eliminate that issue; the music is now muted about 80%, so low you'd hardly notice it. After the voice signal has stopped, the Zulu will bring the music back up over 5 seconds. Schrader added that this feature is selectable so that a backseat passenger can rock out to Chris Daughtry's latest without the continual interruption from ATC.
