The Galaxy Buds line was first introduced in 2019.
The Galaxy Buds3 will have a new design featuring stems, similar to Apple's AirPods. This change is expected to improve fit, microphone quality, and ease of use with the charging case. The Buds3 Pro model will also have an LED strip, called a 'Blade Light,' on each earbud.
No, prior to the Galaxy Buds3, no model in Samsung's Galaxy Buds line had employed a stem design. Samsung's upcoming Galaxy Buds3, set to be unveiled on July 10, will be the first in the series to feature stems2. This design change is intended to improve microphone performance by bringing the mics closer to the user's mouth.
