OPPO Enco X True Wireless Noise Cancelling Earphones ETI51 - Black
- Co-Created with Dynaudio
Advanced technology and decades of Northern European legacy come together in the Enco X earphones, co-created by OPPO and leading Danish HiFi brand Dynaudio, founded in 1977. To bring you digitally precise audio, we evaluated 30 different materials and 152 components, and went through 120 rounds of structural fine-tuning in collaboration with the largest acoustic laboratory of Dynaudio. - Magnetic Balanced Membrane Driver
The Enco X earphones take the same technology as our innovative, award-winning PM-1 headphones, and fit it into an impressively small package. This design extends the reach of high frequencies, delivering crystal-clear audio. - LHDC Wireless Transmission for Flawless Playback
LHDC represents a new era in wireless transmission technology, which retains more detail than traditional SBC and AAC transmission, ensuring that every note comes through with rich, clear sound. - Triple-Microphone Call Noise Cancellation
Equipped with a triple-microphone noise cancellation algorithm, an adaptive filter, and wind detection, the Enco X earphones ensure that your voice is transmitted properly in calls. - Remarkably Long-lasting Battery Life
Enjoy up to 25 hours of music playback on one charge " that's two whole weeks if used for 2 hours a day. Even on long trips, you won't need to pack your charging case. At last, "low-battery anxiety" can be a thing of the past. - All-Weather Protection
The Enco X earphones fear neither rain nor sweat. With IP54 dust and water resistance, these earphones can accompany you through heavy wind, rain, and workouts alike.

| International Protection (IP) code The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes". | IP54 |

| Ear coupling Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression. | Intraaural |
