1 / 7Sony WF-C510 Wireless In-Ear Earbuds, Butter Yellow
Butter Yellow: Sony WF-C510 earbuds are compact, wireless in-ear headphones with ambient sound mode, multipoint pairing and a listed 11-hour battery life. The listing also claims up to 22 hours with the case, IPX4 resistance and a five-minute quick charge for up to one hour of playback. They suit everyday listening and calls, but the listing says noise control is absent, so ambient mode should not be mistaken for noise cancellation.

What to know before buying
Listing details to confirm
Battery figures are use-dependent claims: up to 11 hours from the earbuds, up to 22 hours with the case, and up to one hour of playback from a five-minute charge. IPX4 is stated for splashes and sweat, not immersion. The listing says noise control is None while also describing Transparency Mode and Voice Focus, which is not noise cancellation. Its Built-In Media field says “User Manual, Wireless Charging Case,” but the explicit feature list instead names a charging case and says the charging cable is sold separately. The title/model fields use WFC510/Y while the item-model field uses WFC510/Y5. Check the selected listing for the precise model and package contents.
