Audiovance Euphony EU301 Earbuds Wireless Headphones Bluetooth

Operation

How should I look after EU301 properly?

1. Use the earbuds regularly to avoid over-discharge that can harm the lifespan of the earbuds’ battery. We recommend using EU301 at least once a month.
2. Place the earbuds into charging case for their recharging every time after using them. Leaving them out of charging case is apt to cause over-discharge of earbuds.
3. If you intend to store the charging case, it’s better to fully charge the case or at least charge it to 66% above level.
4. Clean the charging pins on the earbuds and charging case regularly for good contact.
5. Keep the ear tips clean.
6. Keep the microphone hole unobstructed.
7. If you use a hairdryer when earbuds contact liquid, please make sure it’s ‘cool’ wind coming out.

How can I power the earbuds on/off?

Power on:

• When you get the new earbuds for the 1st time using, please remove the protective film covering the charging connectors on the earbuds, then place them back into the charging case to power on.
• The earbuds will turn on automatically when you open the charging case.

Power off:

• Put the earbuds back into the charging case and close the lid, the earbuds will turn off automatically.

Can I manually turn on/off either side of the earbud?

Yes, you can manually turn on/off the individual earbud by

• Long tapping 5 seconds to turn off the earbud,
• Long tapping 2 seconds to turn on the earbud.

How do I avoid triggering the touchpad of earbuds by accident when adjusting their position in my ears or when handling my hair?

• Comparing to other earbuds, EU301 brings less trouble in touch control because Play/Pause and Answer/Hang up are triggered by tapping twice, avoiding the problems by accident.
• Avoid touching the area between Audiovance Logo and LED on earbuds is helpful.

Why is the touch control not responsive every time?

Triple tap the Right or Left earbud to activate voice assistants when using both earbuds. When using a single earbud, triple tap that earbud to activate.

If you are using two earbuds, you can place either one of the earbuds back into the charging case and continue to use another one on its own.
