Hunter's comment
All the earphones on the market now look the same.
Therefore, people with small ears or big ears can only feel uncomfortable with earphones.
Besides, it takes at least a month to make an order.
But Revols customize it to your ears in just one minute.
The method of use can be fixed to fit perfectly by wearing Revols in the ear and using a dedicated app.
Once charged, 8 hours are available and 14 hours can be used with an additional battery pack.
- Customized in 1 minute
- 8 hours can be used when charging once
- Waterproofing
- good sound quality
