These new open earbuds offer head-tracked Dolby Atmos — the best feature of Sonos’ headphones is coming to buds at last

• Cleer Arc 4 are Hi-Res aptX Lossless open earbuds with THX certification
• Arc 4+ model adds Dolby Atmos with Dolby’s own head-tracking
• Arc 4 costs $99.99, Arc 4+ costs $129.99

Cleer Audio has launched the world’s first THX-certified open earbuds, the Arc 4 and the Arc 4+. The Arc 4+ is particularly interesting because that model comes with Dolby’s own head-tracking for Dolby Atmos, a feature previously reserved for over-ear headphones.

These aren’t the first head-tracking earbuds by any means. But rival earbuds use their own tracking setups, whereas these Cleers use the official Dolby version – just like the Sonos Ace headphones, where it works excellently.
