Nank (Naenka) Runner 4 Bone
Conduction Headphones ($80)
Tech and Features
The Runner 4 keeps things simple but smart. They’re
super light, about 26 grams, so once they’re on you barely notice them.
You get both Bluetooth for streaming and 16 GB of
built-in MP4 storage, which means you can load up a bunch of songs and head out
without your phone. Battery life runs close to 8 hours, plenty for long runs or
a full gym day.
Charging and adding music is easy—the magnetic cable
just snaps in, and your computer sees it like a little flash drive so you can
drag songs right over.
Usability Fit
The fit is really comfortable and secure. I didn’t
have any issues with the neckband at all, it just sat in place and I forgot
about it. No hot spots either, even with sunglasses or a hat on.
I tested them on runs, during strength training, and
even through a cardio circuit just to see if they’d slip or bug me. They didn’t
move once and never got in the way, no matter what I was doing.
Performance
Out on a run, I like that I can still hear what’s
happening around me—cars, bikes sneaking up, even birds when I’m on the
trail—while my playlist rolls in the background.
The sound isn’t big on bass, but it’s clear enough for
workouts and voices come through sharp. Battery life felt close to the 8-hour
mark, even with the volume turned up. Calls sound fine unless you’re standing
in heavy traffic.
And every once in a while you’ll feel a little
vibration on the cheekbones when the beat hits, but that’s just part of bone
conduction and it never threw me off.
Conclusions
All in all, the Runner 4 does exactly what it
promises: it gives you music without blocking out the world around you. They’re
light, comfortable, and stay locked in place whether you’re running, lifting,
or just moving through a busy street.
If being able to hear your surroundings is a
priority and you still want reliable headphones for training, these are an easy
recommendation.
Comparisons
Compared to the Shokz OpenRun Pro 2, the Runner 4
doesn’t have quite the same sound polish or extra-long battery, but it makes up
for it with built-in storage and a lower price tag. If you just want great
sound and don’t care about storing music on the headphones, Shokz might edge it
out. But if leaving your phone at home and still having music ready sounds
appealing, the Runner 4 is the more flexible choice.

Jana Herzgova took up running
in 2016, after a back injury. Prior to that she was a speed skater, but due to
back pain and doctor's recommendation, she transitioned into running. Since
then, starting with shorter ultra distance races she quickly evolved into an
avid long distance and unsupported mountain runner. She also loves to take on
challenges/races in arctic and subarctic climates, mainly in unsupported and
semi-self supported style. She currently lives in Utah/Wyoming.
