Sony has announced the $59.99 WF-C510 wireless earbuds, the latest budget offering in its “Truly Wireless” line. They’re fairly bare-bones but improve on their predecessor with voice isolation and slightly longer battery life while costing $30 less. The earbuds come in four colors — black, blue, white, and yellow — and are available for preorder now on Sony’s website or at Amazon.

The WF-C510 earbuds, besides having a name that rolls right off the tongue, come with Ambient Sound Mode (Sony’s transparency mode, which pipes in external sound) in addition to voice isolation. They’re also the “smallest ever closed type earbuds” Sony says it has produced. According to Sony’s specs list, they’ll get as long as five hours of “continuous communication time” or up to 11 hours of general use, when Ambient Sound is off. The charging case can add another 11 hours.

Sony says the earbuds will connect to up to two Bluetooth devices at once and will support Google’s Fast Pair and Microsoft’s Swift Pair features for quick device connections. They’re also IPX4-rated, which means they can take water splashes or a sweaty run (but you shouldn’t drop them in a pool).

The WF-C510 are expected to ship to customers starting September 9th.
