Unbranded ETE51&ETE52 OPPO Air3 Pro

Natural listening
Taken from nature, the treble area is more natural and durable
The world's only application of bamboo fiber to the dome of micro-speakers. Compared with Enco Air2 Pro's titanium-plated diaphragm, the internal damping of the CBF material is greater
(experimental video comparison: the CBF material is dropped for 3 seconds, and the titanium plate is dropped for 8 seconds), and the listening experience is softer.
Through the developed front cavity customization kit, the sound cavity layout is optimized, and the sound of bamboo fiber is clearer.
