Bose Ultra Open Earbuds vs Sony LinkBuds S
The Verdict
Both earbuds target premium listeners but serve different priorities. Bose Ultra Open emphasizes spatial audio with head-tracked Immersive Audio and directional OpenAudio technology, ideal for movie fans and gaming enthusiasts willing to sacrifice active noise cancellation. Sony LinkBuds S counters with proper ANC, hi-res LDAC codec support, and a lighter 4.8g design per bud versus Bose's 6.5g, making them more comfortable for extended wear. Battery life favors Bose at 7.5 hours per charge versus Sony's 6 hours with ANC engaged. Price-wise, Sony's $199 positioning undercuts Bose by $100, delivering ANC and hi-res audio without the open-ear design compromise. For commuters and travelers requiring noise isolation, Sony LinkBuds S offers better value. For spatial entertainment and those preferring awareness of surroundings, Bose Ultra Open justifies its premium. Sony edges ahead due to ANC inclusion, superior portability, and compelling pricing.
