Hi there, Our S1 earbuds cannot adjust the volume. Thanks for your attention. If you have any question, please feel free to contact us.

Yes. That is what the “TWS” means (in case you want to look for a similar pair if these aren’t to your liking). So you can use say the right ear bud then once that dies switch to the left.

As with all Bluetooth earbuds, these should work with any device that enables Bluetooth connections, which all iPads and iPhones do.

Thanks for your attention. Votomy S1 wireless earbuds come with 6 silicone ear tips, size up from S / M / L which are suitable for the majority of ears. Because our wireless earbuds need to be worn tucked into the ear, which is not suitable for the size of children's ears. Any product purchased from our store enjoys a 12-month warranty. Please feel free to contact us if you concerns for the product, and we will reply to you within 24 hours as soon as possible.
