Philips WFL900/H sleep headphones

The Philips WFL900/H combines a soft eye mask with on-ear headphones for side sleepers and travellers. Bluetooth 5.4 connects to phones and tablets within 33 feet. Thin silicone-covered speakers sit flat against the ears. The adjustable band fits head circumferences from 20 to 26.5 inches.

Battery life and sustained playback

A 1 to 2 hour charge delivers up to 14 hours of continuous audio. The upgraded battery chip prevents low-power beeps that could disturb rest. Button controls on the module handle play, pause and calls without reaching for a device. Universal compatibility keeps pairing simple across platforms.

Thermals noise and power draw

Passive noise cancelling relies on the snug mask seal rather than active circuitry. The lightweight memory foam and ice silk lining stay cool during extended wear. No fan or active cooling is present so operation is silent. The lithium-polymer cell powers the 32 ohm dynamic drivers without external supply.
