I lost my air buds can I get new ones?"

”Air buds” are not an Apple product.

Perhaps you mean:

• AirPods. AirPods - Apple
• EarPods. These come in the box with recent model iPhones. https://www.apple.com/shop/product/MMTN2AM/A/earpods-with-lightning-connector?fnode=f8b2d91f20eafc6f9ad2572d12bfcbca8e2caa866df1b450f392883d943cd980c9d8fcf9ddc66d4014d2a282c64f76f8b14063804138263d0f0233008bb78b58293575a6e68184ee497eb5112f052084c3a6e6b9448d4088a51ebd11c5fbac8c2ed3e213f67d2e91a2d058fec75f295262ce2e6b55af03cfd6aabad41836047c

In any event, you would pay retail price for either product.

If you lost just the Airpods but not the case: If your AirPods are lost - Apple Support

If you lost all 3 items you come out ahead buying new ones.

You're welcome.
