Comfortable design for side sleepers

The Philips IMAGE S4-WHITE WFL900/H combines a sleep mask with integrated headphones. Premium cotton material feels ultra-soft and breathable against skin. Adjustable bending cartilage blocks light from the nose area. Removable speakers and Bluetooth module allow the mask to be washed.

16 soothing sounds and Bluetooth 5.2

Sixteen built-in white noise options play without a connected device. Bluetooth 5.2 enables wireless streaming from smartphones or computers. Speakers can be repositioned inside the mask for optimal alignment with ears. Type-C charging replenishes the 240mAh battery.

Battery life and passive noise reduction

Playback lasts over 15 hours on a single charge, sufficient for multiple nights. Passive noise cancelling relies on physical seal rather than active electronics. No active noise cancellation or wired audio input is included. Buyers who need longer runtime or ANC should consider other solutions.

Questions about this item

How often will the 240 mAh battery need recharging if I use the mask every night?

The battery provides over 15 hours of playtime per charge, so nightly use of around eight hours will require recharging roughly every two nights.

What is the first limit I will hit during an all-night session — battery life or Bluetooth range?

Battery life is the limiting factor; the mask runs for over 15 hours on a full charge, while Bluetooth 5.2 maintains a stable connection throughout a typical bedroom.

Will the speakers or electronics get warm against my face after several hours of continuous playback?

The low-power Bluetooth 5.2 chip and 240 mAh battery generate negligible heat, so the mask remains comfortable against the skin during extended overnight use.
