Sound quality was the biggest reason I enjoyed the Shokz OpenRun Pro 2. I used them for running, cycling and mountain walks. Of the Shokz models I had used by the time of this test, these sounded best to me. There were compromises, though: calls in wind and the IP55 rating were my main reservations. This review separates my experience from the manufacturer’s specifications.
DualPitch: bone and air conduction
OpenRun Pro 2 leave the ear canals open. DualPitch combines bone and air conduction, so describing them solely as bone-conduction headphones misses part of the design. My earlier OpenRun / Aeropex review (in Polish) provides context for my experience with the range.
I could hear music and sounds around me during training. That is useful, but it does not guarantee that every approaching vehicle will be audible. Wind, traffic noise and playback volume all affect what reaches you. Keeping your ears open still requires attention to the road.
Sound quality: the highlight of my test
To my ears, the sound was fuller and more enjoyable than on the Shokz models I had used previously. I appreciated that most when listening to music while moving. OpenRun Pro 2 do not replace headphones that isolate you from outside noise: openness is part of their purpose, and surrounding sounds compete with your music. If you want quiet and isolation, this design serves a different need.
Case, charging and IP55 protection
The supplied hard case is a practical travel accessory. It gives the headphones a dedicated place instead of leaving them loose in a backpack.
The USB-C port sits under a cover. Personally, I preferred the earlier magnetic charging arrangement because I did not need to open a flap. OpenRun Pro 2 are rated IP55 and are not intended for swimming. There is no evidence here that USB-C itself caused the protection rating. My concern was the protection margin for frequent wet sessions, rather than a documented failure in rain.
Battery: around nine hours in my use
I got around nine hours of listening in the use described in my original review. I did not document a controlled volume and playback protocol here, so this is an observation from that test rather than a guaranteed result for every user.
Shokz quotes up to 12 hours of playback, a full charge in about an hour, and up to 2.5 hours of listening from a five-minute charge. My original notes described roughly 1–1.5 hours after a quick top-up. Those figures come from different conditions; the advertised figure is not my own measured result.
Controls and the Shokz app
The physical controls were easy for me to use while moving. Power is controlled with the volume-up button, while the multifunction button handles playback and calls. I did not need to reach for my phone for every track change.
The Shokz app worked without problems in my use. I used its sound settings and connection management. Saved pairings should not be confused with simultaneous connections: multipoint supports two connected devices.
For training at home, I want headphone controls to stay out of the way of the session. Fit and physical buttons are worth trying during the movements you actually do.
Cycling: comfortable fit, wind-sensitive calls
The headphones worked well with my helmet and glasses. They stayed in place and did not get in my way. That reflects my particular combination of equipment: it is worth checking the fit with your own helmet and frames.
At around 30 km/h and a little faster, music was still audible. I could also hear traffic around me. Calls were much less useful in stronger wind or above roughly 20 km/h in my test. That describes those conditions, rather than a fixed speed limit for the microphone.
If calls are your main priority, my OpenComm 2 review (in Polish) is another reference point. A boom microphone alone does not guarantee clear calls in all conditions.
Running and a connection check at the track
On runs, I liked the stable fit, straightforward controls and music playback. Calls were acceptable in my attempt at around 5:30 min/km. That pace is not a universal microphone threshold: wind and how you speak also matter.
I left my phone in a backpack at the track and ran a 400-metre lap. Playback continued, with interruptions at the furthest point. My original description estimated around 200 metres from the phone, but I did not measure the distance. I would not present that estimate as a verified wireless range. This was an informal observation in open space, rather than a guaranteed specification.
Video review
The original review video below is in Polish.
Before a session or a race
Check the fit, battery charge and the organiser’s headphone rules before an important run. I would try a new combination of headphones, cap and glasses in training instead of saving it for race day. These small checks belong in the preparation, alongside the rest of your kit.
What stayed with me after the test?
Sound and comfort in motion were the strengths I remembered most. Wind affected calls, while IP55 remained my main reservation for frequent wet sessions. The right choice depends on whether music, calls or immersion protection matter most to you.
Verdict: who are OpenRun Pro 2 for?
I recommend considering them for running and cycling if you want comfortable open-ear headphones with an emphasis on sound. Audio was the standout feature in my test. I would not choose them for swimming or for blocking out surrounding noise.
For my own frequent wet training, I leaned towards Shokz OpenSwim Pro (review in Polish), accepting sound I liked slightly less. That reflects my priorities; it does not establish that OpenRun Pro 2 cannot handle an ordinary run in rain.
Frequently asked questions
Are these exclusively bone-conduction headphones?
No. DualPitch combines bone and air conduction while leaving the ear canals open.
How long does the battery last?
I got around nine hours in my use. Shokz advertises up to 12 hours; actual runtime depends on conditions.
Can I swim with them?
No. IP55 does not mean protection against immersion. Swimming requires a model intended for that purpose.
Are they good for phone calls?
Calls were acceptable on a steady run in my test. Wind made them much less useful on the bike.
Will I hear my surroundings?
The open design lets outside sounds reach your ears, but it does not guarantee that you will hear every hazard.
