What to know before buying

The listing claims IP7 waterproofing in its title and IPX7 in its feature copy. Treat this as a manufacturer claim and follow the product's care guidance, particularly around water exposure.

Listing details to confirm

Bluetooth version is inconsistent: the title and product details state 5.4, while one feature description also claims 5.3. The listing also gives 14.2 millimeters for the driver in product details but describes a 13mm speaker in its feature copy. Battery claims distinguish 10 hours per charge from 50 hours with the case, and customer feedback reports mixed battery life. Check the selected listing for the exact configuration and included charging cable before buying.

Frequently asked questions

How long do the Rulefiss B01 earbuds last per charge?

The listed battery life is 10 hours. The feature description separately claims up to 50 hours when including the charging case, so these are not the same runtime figure.

Are these suitable for exercise?

The in-ear shape and ear hooks are presented for sports and running. The listing also claims IPX7 protection, but this remains a manufacturer claim rather than a verified result.

What Bluetooth version do they use?

The product title and details state Bluetooth 5.4, but a feature description also states 5.3. The listing is inconsistent, so confirm the version for the selected item.

Do they include active noise cancellation?

The listing describes environmental noise cancellation for calls. It does not establish active noise cancellation for listening to music.
