Philips WFL900/H X500 Bone Conduction Headphones

Open-Ear Bone Conduction Design

The Philips WFL900/H X500 uses bone conduction drivers that transmit sound through the cheekbones, leaving the ear canals completely open. This allows runners, cyclists and outdoor athletes to hear music or podcasts while staying fully aware of traffic, voices and ambient sounds. The lightweight wraparound frame stays secure during jogging, gym sessions and hiking without the pressure of traditional earbuds.

IP67 Waterproof Sustained Use

Rated IP67, the headphones resist sweat, heavy rain and temporary immersion during long training sessions. The sealed construction protects internal components from moisture ingress throughout extended workouts, early-morning runs or wet commutes. Battery life reaches 12 hours per charge, supporting multiple consecutive outings without needing the magnetic charging cable. Bluetooth 6.0 maintains a stable link up to 15 metres even during continuous movement.

80 Ohm Input Impedance

The 80 ohm input impedance determines how the headphones draw power from the integrated battery and match the Bluetooth 6.0 amplifier stage. This electrical characteristic fixes the volume headroom and driver control available from the true wireless design. Buyers who need a different impedance match for external amplifiers or wired sources should look elsewhere, as this model operates solely on its internal battery and wireless connection.
