The new model of fully wireless headphones Huawei FreeBuds Pro 2+ became the first in the world capable of measuring the user’s temperature and pulse rate. Measurement of heart rate can be carried out both in continuous mode and on demand. According to the manufacturer, the measurement accuracy is 95% compared to traditional methods.
The acoustic part of the headphones was developed jointly with the French company Devialet and is built on an armature driver and an 11 mm dynamic driver. The latter uses a magnetic system with four magnets, which increased the return by 30%. The stated lower limit of the headphone frequency range is 14 Hz . Headphones support L2HC and LDAC codecs , allowing you to transmit a high-definition signal at a frequency of 960-990 kb / s.
