OPPO Enco M33

A notable alternative to the popular TWS-class in-ear headphones as envisioned by OPPO. The model is made in the form factor of a Bluetooth headset with a neckband and provides Hi-Fi sound. However, Hi-Res Audio certification and LDAC codec support for headphones are not provided. OPPO Enco M33 has 12.4 mm audio drivers with frequency spectrum coverage from 20 Hz to 20 kHz and sensitivity up to 118 dB.

Moreover, the model has acquired an ANC active noise reduction system - a trio of microphones absorb ambient noise in a volume range of up to 45 dB, and clear the voice during calls on a paired phone. The headphones are connected via the Bluetooth v 5.2 wireless protocol with quick switching between devices if necessary. The body of the model received protection from dust and moisture according to the IP55 standard. On a fully charged 220 mAh battery, up to 20 hours of listening to music with noise reduction turned on and about 28 hours of battery life of the headphones without using noise reduction are promised. The headset comes with three pairs of silicone ear pads of different sizes.
