Sound: EXTRA BASS™ from 12mm neodymium

Sony’s EXTRA BASS™ is not just a badge — it is a tuning philosophy that the XB line has refined across generations. The 12mm dynamic drivers (larger than the WI-C100’s 9mm units) move real air with the authority that neodymium magnets provide, delivering deep, punchy low-frequency response with enhanced bass that you feel as much as hear. The tuning stays Sony-honest: bass-forward without burying vocals, treble smooth at volume. The sealed in-ear fit with three tip sizes adds the passive isolation that lets the bass land against quiet. SBC and AAC codecs cover all devices over Bluetooth 5.0. The sealed tips pressurize the canal slightly, reinforcing the low-end that EXTRA BASS tuning delivers. The sealed tips pressurize the canal slightly, reinforcing the low-end that EXTRA BASS tuning delivers through the 12mm drivers.

Battery: 15 hours and quick charge

The internal battery runs 15 hours of playback or talk per charge, with a full refill in about 3 hours via USB-C. Sony’s quick charge returns 60 minutes of playback from 10 minutes of charging — the tea-break top-up that carries the rest of the commute. Standby reaches 200 hours.
