Harman Second-Gen Everest Bluetooth Headphones Led by Upgradable Model

Harman released its second-generation JBL Everest Bluetooth headphones, led by the $299 Elite 750NC around-the-ear model with adaptive noise canceling that allows users to control the amount of noise they want to block out. The 750NCs also have TruNote automatic sound calibration, which adjusts sound based on the user’s ear anatomy for optimal listening, Harman said. The My JBL Headphone App gives users access to customization and over-the-air software updates, and the Everest Elite software development kit gives developers access to the headphones’ nine-axis motion sensor and programmable buttons “to change how listening experiences can be customized beyond music,” said the company. Battery life is 15 hours with noise canceling, 20 without, it said. Additional models are the on-ear Everest 710 ($249), on-ear 310 ($199) and in-ear 110 ($99).
