The Sense Pro pulls ahead in several meaningful sound quality metrics. Its driver is marginally larger at 16.2 mm versus 15.4 mm, but the more impactful difference is sensitivity: the Sense Pro's 92 dB/mW sound pressure level versus the Sense Lite's 86 dB/mW means it can produce noticeably louder output from the same power input — a 6 dB gap is perceptible and translates to a fuller, more dynamic listening experience at equivalent volume settings.
Frequency range tells a sharper story. Both earbuds floor at 20 Hz, covering the standard lower limit of human hearing, but the Sense Pro extends to 40,000 Hz — double the Sense Lite's ceiling of 20,000 Hz. While humans cannot consciously hear above roughly 20 kHz, the extended high-frequency headroom is associated with improved transient response and overtone reproduction, which audiophiles argue contributes to a more ″airy″ and detailed sound. The Sense Pro also supports spatial audio and benefits from passive noise reduction courtesy of its in-ear seal, giving it a more immersive and focused listening environment that the open-ear Sense Lite simply cannot replicate.
Both share identical 32 Ohm impedance and neither includes ANC, Dolby Atmos, or Dirac Virtuo. Still, across every differentiating sound quality metric — sensitivity, frequency ceiling, spatial audio support, and passive isolation — the Sense Pro holds a clear and consistent advantage over the Sense Lite.
