OPPO Enco W31 Ture Wireless Headphones with IP54 protection against water and dust

OPPO launches a new technology in the OPPO Enco W31 True Wireless Headphones with IP54 compliant against water and dust.

Instead of being divided into first-choice headphones and second-hand headphones, the audio can be heard from both ears at the same time, resulting in faster and smoother transmission. At the same time, the system can be extensively tuned to avoid delay, lagging, incompatibility, distractions, improve signal quality, and listen without interruption or inconvenience. Photo Source https://www.oppo.com/mm/

The W31 headset is designed to protect against water and dust in accordance with IP54 standards. Your headphones will be fully protected in all situations where you’re living inside or outside of the house.

IP54 is an international standard for measuring water purification protection that can occur from anywhere. There is no guarantee that all dust is completely protected, but a small amount of dust will not affect the performance of the headset. This measurement is only used to measure the headset. Photo Source https://www.oppo.com/mm/
