1.0 Thanks for Choosing Our Products
TOZO T20 ENC earbuds offer an extraordinary experience of stable voice calls with fashionable appearance and multiple functions, making them a great choice for work, outings, and driving.
2.0 Truly Wireless Environmental Noise Cancellation Technology
These earbuds utilize true wireless technology, allowing connection to compatible devices without cables. They do not require the phone to face the earphones directly, with a maximum distance of approximately 12 meters (about 39 steps). The Environmental Noise Cancellation (ENC) technology effectively inhibits up to 90% of reverse environmental noise, reducing ambient noise by up to 35dB, which enhances voice communication for users, including gamers. A double microphone array accurately calculates the speaker's position, focusing on the target voice while filtering out environmental interference for clearer conversations.
