Sound Quality and Performance
The JBL Live 670NC delivers the brand’s signature powerful, dynamic sound with enhanced clarity across all frequencies. The 40mm drivers provide robust bass response without overwhelming mids and highs, making them versatile for all music genres from classical to electronic dance music.
The True Adaptive Noise Canceling system automatically adjusts to environmental conditions, providing up to 30dB of attenuation around 250Hz – effectively eliminating engine rumbles, air conditioning hum, and consistent background noise. While not matching premium over-ear models, the ANC performance is impressive for on-ear headphones in this price range.
JBL Spatial Sound creates an immersive virtual surround experience with dedicated presets for video, movies, and gaming, transforming stereo content into a wider, more engaging soundstage.
