Sudio ETT True Wireless Earbuds - Active Noise Cancelling, Transparency Mode-Complete Features/Instruction Guide

True wireless headphones are Bluetooth earbuds or in-ear monitors (IEMs) that do not have cords or wires connecting them to a source of sound (smartphones, MP3 players, tablet, etc.). The mic, controls, and battery are integrated into the earphones’ housing because they don’t have any cables.

Before getting started

The earbuds will likely have some existing battery charge, however, it is recommended to fully charge Ett before using it for the first time.

Turning Ett on or off

Ett powers up as soon as the earbuds are removed from the charging case, as indicated by the LED lights on the earbuds and the audio feedback Pairing.

Similarly, Ett is turned off when placing the earbuds back into the case.
You can also use the button controls to power the earbuds off. Do this by holding the button for 7 seconds on either earbud.

Care and cleaning

Cleaning your earphones on a regular basis will ensure the best possible sound performance and prevent them from wearing out sooner than expected. Use only a slightly damp cloth when cleaning the earbuds and/or case. You can also use a fine brush or cotton swab to gently clean the earbuds and inside the case, avoiding damage to the charging connectors (copper pins). Avoid using alcohol or chemicals, as this can damage the rubber coating on the earbuds and case. In some cases, being exposed to strong sunshine or high heat might alter the form of the silicon material.
