Phantom Bass
Phantom Bass is a technology that uses perceptual audio processing to restore low-end perception, boosting sub-bass harmonics to restore depth and impact, delivering a natural, open sound with full, powerful bass. This feature is particularly beneficial because open-ear designs naturally lose low-frequency impact due to air leakage.
