The market for flagship aviation headsets has a new model with the $1099 Lightspeed Zulu 4 announced ahead of AirVenture 2025. It picks up where the Lightspeed Zulu 3 left off (still in the product line), using the same noise canceling electronics and physical construction, but with newly designed FrameFit earseals that are more eyeglasses and ball cap friendly. It also has dual Bluetooth connectivity and AINR microphone circuitry that reduces mic audio noise when talking over a telephone with the Bluetooth connection.
