JBL Live 660NC vs Sony WH-XB910N Extra Bass

The Verdict

JBL's Live 660NC delivers exceptional value at $149, offering 40 hours of ANC playback versus Sony's 30 hours despite costing $100 less. Both feature 40mm drivers and over-ear designs weighing under 260g, but their sound signatures diverge significantly. Sony's WH-XB910N emphasizes extra bass with a punchy low-end profile and superior codec support including LDAC for higher-quality wireless audio, making it ideal for bass enthusiasts and audiophiles. JBL prioritizes balanced sound with its signature house sound, broader ANC flexibility with Ambient Aware and TalkThru modes, and faster quick-charge capability (10 minutes yields 4 hours versus Sony's 4.5 hours). Both support multipoint Bluetooth 5.0+ connectivity and built-in voice assistants. Sony's Bluetooth 5.2 and 360 Reality Audio provide immersive spatial sound when available. Battery life heavily favors JBL, particularly for ANC users who'll stretch 40 hours before recharging. For budget-conscious buyers prioritizing longevity and balanced sound, JBL wins decisively. Sony justifies its premium for bass lovers and those wanting advanced audio codecs and spatial features. Choose JBL for daily value and endurance; pick Sony for bass-forward tuning and audiophile potential.
