It's no secret anymore that Samsung is working on a proper successor to the Galaxy Buds+ called Galaxy Buds X. Or they would probably co-exist, but given the rumored price of around $140, we suspect the Buds X will replace the older generation.
Anyway, according to the US Patent Office listing, the Galaxy Buds X will offer active noise cancellation undercutting Apple's AirPods Pro and the Pixel Buds 2. The design also looks a little funky from those leaked renders from a month ago.
Since the pair stopped by the US Patent Office, Samsung is perhaps gearing up for a release sooner than we might think. Stay tuned.
