Wireless charging, through the phone: These earbuds' coolest trick is that their contactless charge-enabled case works with Samsung's new Wireless PowerShare charging on the back of the Galaxy S10 phones. Drop them on your phone, and they'll charge up, at the equivalent of 5W (a rough estimate of a fully dead case to fully charged would be an hour). The case can also charge via USB-C.

Smaller than previous Samsung earbud cases: Samsung says the Galaxy Buds are 30 percent smaller overall than the Gear Icon X earbuds. According to Samsung, dropping onboard music playback from the Gear Icon X helped shrink these new Buds. (The Buds in their case still end up being a bigger package overall than AirPods.)
