Please go to setting>bluetooth and unpair/forget the TWS-I7 devices.
Then get your earpods, long press the earbuds until they flash red/blue. When this happens double tap, the left earbud until it or the right one stops flashing red/blue and just flashes blue. When this happens go to setting>bluetooth and you should only see ONE TWS-I7 in your my device section. Tap that and it will pair them together.
When you go to setting>bluetooth
Does it show two TWS-I7 under the My devices or other devices?
If it shows TWS-I7 twice in the my devices section click the I and click forget device.
