Bone conduction (or Open-Ear) headphones transmit sound by inducing jawbone vibrations, freeing your ears to hear outside sounds. This makes them ideal for women runners who, unfortunately, need to be more aware of threats when running alone. My wife has enjoyed a pair of Shokz for years, but I was intrigued when I heard of a waterproof version.

Overall First Impressions/Controls
I’m not an audiophile, but I had trouble believing that this technology could produce the same quality of sound as regular earphones. My favourite songs sounded the same.

The only controls are two volume buttons on the right side, and a “multi-function” on the left. The multi-function has to be pressed a combination of times to advance or go back a track, held down to enter pairing mode, etc. The volume buttons are used to power the device on/off in addition to obviously controlling the volume.
Normally I prefer to have more dedicated controls rather than memorizing combinations to accomplish basic tasks, but I can see how not having to fumble around searching for the right button when the headset is being worn is actually more practical and user-friendly.
Bike Test
My first test of the OpenSwim Pro was on a bike ride. Normally, headphones would be a big no-no on the bike, but the open ear should mean that a rider can maintain situational awareness. On this ride, the way out was mostly downhills and steep ones at that, so I didn’t listen to music at all, because I wanted my full attention on handling my bike through the turns and such. I had planned to listen to music to motivate me up the steep climbs home. Unfortunately, I remembered to turn on the music a little late, but for the last stretch, I did notice that I could hear a car come up behind me as I rode.
Run Test
I brought the headphones with me on a run around the track at the town stadium. I had the music playing while I used the bathroom before my run – what was interesting is when I used the hand dryer, I couldn’t hear the music anymore. So loud sound coming in your ears will override the music coming in through your jawbone vibrations.
During the run, I was able to have conversation with my wife when I passed her on the track without turning down (or off) the music.
Swim Test
So the headphones are waterproof, but that doesn’t mean they can connect to Bluetooth while in the water – this is made clear by the manufacturer. So for swimming, you use them as an MP3 player; remember those? You have to load MP3 or other audio files from a computer over the USB cable to the memory of the OpenSwim Pro. MP3s are getting a little hard to come by, but I still had some songs loaded on my phone (in unprotected m4a format from iTunes) that I loaded onto my computer and then back to the headphones.
The headphones convert from Bluetooth to MP3 mode by pressing the 2 volume keys simultaneously. On my first swim, I absolutely loved hearing music and the laps seemed to tick by with less boredom and tedium. The headphones hug my head and can almost be forgotten, which is a far cry from the “listening to music while swimming” I had over 10 years ago.
Other Applications
I’ve used these headphones a bit in the office as a way to listen to music or be on a call while having a better awareness in my surroundings; e.g. a co-worker wants my attention. The microphone seems to work well for calls, though I prefer noise-cancelling headphones for longer sitting periods of meetings or deep work.
Conclusion
So far, the Shokz OpenSwim Pro is one of the best electronics purchases a multi-sport athlete could buy.
