How To Fix TOZO Earbuds Not Charging? – Easy Fixes!

Tozo is a great brand for budget-friendly wireless earbuds. Tozo T6, T10, and NC9 are extremely popular wireless earbuds that flawlessly work with Android and iPhones.

I have used TOZO NC9 and TOZO T10 wireless earbuds for the past few months. It gives great battery life with ANC. The single earbuds have a 70 mAh battery that gives up to 13 hours of music playtime.

But, I recently encountered a charging and pairing issue with my Tozo left earbud. So, I contacted the customer support team, who provided some troubleshooting steps to fix the charging issue.

An invisible layer of wax buildup around the metal contacts was causing problems in charging my left TOZO earbud. I cleaned the metal contacts with isopropyl alcohol and a microfiber cloth, and the charging issue was fixed. Several more reasons, such as inappropriate placement of earbuds, low battery on the charging case, buggy firmware, faulty case, etc., also causes charging problems.

High temperature is the biggest enemy of Li-ion batteries. If there’s a high temperature near your charging station or TOZO buds are hot, then it won’t charge.

If your TOZO T10, T12, or T6 buds are hot, let them cool down for a few minutes.

Also, do not use a fast charger to charge your earbuds. Always use the original USB-C cable and the normal power adapter to charge any TWS buds.

Your Tozo left or right earbud is not turning on or not working because that earbud isn’t charging in the case. First, remove it from the case and clean the metal contacts with toothpicks and rubbing alcohol. Place it back into the case and leave it connected to the charger for 30 minutes.

Why Are My Tozo Earbuds Blinking Red and Blue?

The indicator light shows the current status of your earbuds. The red light indicates that your earbuds are discharged, and you should connect to a charger.

Once you connect the charger, the indicator color will change to purple. A solid green light indicates that your earbuds and case are fully charged.

If your Tozo earbuds are blinking red and blue, they are not paired or face problems in pairing. You should factory reset and pair them again.

How Do I Know If My Tozo Earbuds Are Fully Charged?

Your Tozo earbuds indicator light will be red if the battery is low. Once you connect the charger, the led will turn purple (white in some models) and go solid green when the battery is fully charged.
