Read size labels and water ratings separately
Distinguish variant labels from measured usable length and read the original care instructions.
Compare variant labels as labels
The selected X-5 is labeled 7.25 inches and the selected X-10 is labeled 11 inches. Neither storefront size option labels that number as usable length. Find a labeled diagram or ask for measurements of the specific segment.
Use exact measurements when comparing other designs
For a comparison organized around measured bead diameter and usable length across brands, see the guide to published bead measurements.
Read the care directions alongside the rating
The retailer lists IPX7 for each of these models. Keep the model’s charging instructions, cleaning instructions and rating together. The rating alone does not identify how to clean or dry a connector.
