Shokz has recently introduced the OpenRun Pro 2s in Hong Kong. Identified as model S822, it combines bone and air conduction through DualPitch, with Dolby Audio and a built-in metronome. Its Hong Kong introductory price is HK$1,599, also currently listed by Fortress. For runners who listen to music or podcasts, the useful distinction is between three functions: transmitting sound, providing a cadence cue and controlling playback with physical buttons.
Why combine bone and air conduction?
DualPitch assigns different frequencies to two drivers. Bone conduction handles the mid and high ranges, while an air-conduction bass driver uses an 18 × 11mm diaphragm for lower frequencies. The design therefore spreads sound reproduction across two transmission paths. Calling it simply a bone-conduction headphone no longer describes the whole arrangement.
Two side units and a connecting band form the sports-headphone silhouette.
The two drivers must work together, with fit and volume also affecting the listening result. A useful comparison starts with familiar voices, rhythms and musical passages, rather than treating more bass as an automatic advantage. Whether speech remains clear, drums overpower a voice or the balance changes during movement are more concrete questions than a feature name alone.

How do Dolby Audio and the metronome differ?
Dolby Audio can be enabled in the Shokz app as a listening-effect option. The metronome instead supplies a regular cue and can play alongside music or a podcast. One changes the presentation of sound; the other helps establish a training rhythm. They serve different purposes, while physical buttons keep operation from depending entirely on a phone screen.
The value of a metronome lies in consistency. It does not automatically determine the correct cadence for every runner. Layering a cue over a familiar song offers a way to compare the steadiness of movement. With a dense interview, however, the same cue may compete for attention. Simultaneous playback provides an adjustment tool that users still need to match to their training.
How should battery life and protection be read?
The product specifies up to 12 hours of playback and three hours of listening from a five-minute charge. Protection is rated IP57, with a double-layer mesh structure and waterproof mesh in the housing. These are stated product conditions; volume and enabled functions can change actual battery life. Check the S822 model designation when comparing specifications, so that Pro 2s figures are not mixed with another OpenRun generation.

An open-ear fit leaves the ear canal unblocked, but environmental noise, wind and playback still share the listening environment. A route that moves from city streets to a sports ground may call for different volume and cue settings. The OpenRun Pro 2s is therefore interesting beyond its Dolby badge: it gives music, a regular training cue and physical control distinct jobs that runners can combine around their own routines.
