Doogee D11 Audio and Sensors

Audio and Sensors

The Doogee D11 lacks a loudspeaker and a 3.5mm headphone jack, steering its usage towards users who align with its fitness-centric features. The focus is further emphasized by the onboard sensors, including an accelerometer, heart rate monitor, and SpO2 sensor. These sensors enable users to track physical metrics such as heart rate variability and oxygen saturation levels, which are critical for health monitoring.
