Nank Runner Diver 2 Pro headphone

If you’re looking for a pair of headphones that you can take anywhere—literally, even underwater—the Nank Runner Diver2 Pro is worth checking out.

If you’re someone who likes to stay active—whether it’s swimming, running, or just being outdoors—finding the right headphones can be a bit of a challenge.

Regular earbuds tend to fall out, and most over-ear headphones aren’t exactly built to handle sweat, let alone a dip in the pool.

That’s where the Nank Runner Diver2 Pro comes in. These bone conduction headphones are designed to give you good sound quality without blocking out the world around you. Plus, they’re waterproof.

I have been using the Nank Runner Diver2 Pro for three weeks and have worn them over 100 hours, and I am ready to give you my review.

Let’s dive in (pun intended) to see if they live up to the hype.

What’s in the Box?

Unboxing the Nank Runner Diver2 Pro, you get the headphones themselves, a magnetic charging cable, two earplugs, six “sound quality enhancers”, a silicone adjustable strap, and a user manual.

The magnetic charging cable is a nice touch—it snaps on easily and makes charging straightforward, especially when you’re on the go. The same cable is used to transfer audio files from a computer to the internal storage.

Design and First Impressions

Right off the bat, you notice these headphones are lightweight. They’re made to wrap around the back of your head, sitting snugly on your cheekbones.

It’s a pretty comfortable fit, even after wearing them for a few hours. The open-ear design means you don’t have anything sticking into your ears, which is a win for comfort.

Plus, it keeps you aware of what’s happening around you—pretty handy if you’re running on busy streets or need to listen for instructions at the pool.

The build feels solid. They’re flexible enough to handle some rough handling, and they’re designed to stay put whether you’re swimming laps or hitting the trails.

The earpieces fold in to cover more of your ears. According to Nank, this is how you enable noise-canceling. To me, it doesn’t really cancel out any noise, but it did improve the sound clarity.

And, speaking of swimming, these come with an IP69 waterproof rating. That means they can handle being submerged in water up to 10 meters deep.

I’ve tested them out in the lake near my house, and they work just as well underwater as they do on land—something that a lot of so-called waterproof headphones can’t claim.

Sound Quality – How Do They Actually Sound?

Now, let’s talk sound quality. If you’re expecting the same deep bass and crisp highs you’d get from a pair of premium over-ear headphones, you might want to adjust your expectations.

Bone conduction headphones work differently—they send sound through your cheekbones instead of directly into your ears.

The result? You get a decent range of sound with a good balance of mids and highs. The bass is there, but it’s not going to shake your bones.

That said, for what these headphones are, the sound quality is pretty solid. Music sounds clear, and you can easily hear podcasts and audiobooks.

The sound quality and listening experience is very similar to my Bose Frames and Razer Anzu smart-glasses.

As somebody that likes to listen to music on hikes but don’t like being shut off from the world around me, these are great.

In my experience, how good they sound is going to depend on the size and shape of your head. My head is quite large, but I couldn’t get the headphones to sit very tight which impacts the sound quality.

If I hold them tighter on my cheekbones, the clarity of the sound improves, but I was not able to wear them like that. No matter what I tried.

Nank includes an adjustable strap made out of silicone, that is supposed to be worn for a tighter fit, but that didn’t work on me. Maybe my head is too large?

I didn’t find the “sound quality enhancers” to improve the sound for me, but that might be because of my large ears. I preferred the sound without them.

They don’t get crazy loud, which is a downside and something that bothered me on bike rides when the wind was blowing. I had to use the included earplugs to hear the music better, which makes the sound muffled.

I tried using the “sound quality enhancers” but they weren’t enough to block the noise of the wind.

The volume wasn’t a problem when swimming, hiking, running, or walking though.

Bluetooth and MP3 Modes – Two Ways to Listen

One of the standout features here is the dual-mode setup. You can use them like any regular Bluetooth headphones when you’re above water, thanks to Bluetooth 5.4.

The connection is stable, and pairing them with a phone is quick and easy. But, as you probably know, Bluetooth doesn’t really work underwater. That’s where the built-in 32GB storage comes in.

You can load thousands of songs directly onto the headphones and switch to MP3 mode when you’re swimming. It’s a game-changer for those long pool sessions.

I could not download Spotify playlists directly to the headphones, which is a minus. That’s because Spotify doesn’t download music in listenable files, but uses DRM-protection that requires Spotify software to listen to.

Switching between Bluetooth and MP3 modes is quick and easy, with a button press doing the trick. Once you’ve got your music loaded on, you don’t need to worry about being tethered to your phone, which is super convenient, especially if you’re doing laps or going for a long run.

Battery Life – Enough to Keep You Going

Battery life on the Nank Runner Diver2 Pro is advertised at around 10 hours.

In my experience, that’s pretty accurate. You get a full day of mixed-use without needing to recharge.

When it does come time to top up, the magnetic charger gets them back to full in about two hours, which isn’t too shabby. A quick 10 minute charge will get you enough battery to listen for 60 minutes.

Real-World Use – Do They Stay Put?

So, how do they hold up in real-world use? Surprisingly well. They don’t budge during most activities.

Whether you’re diving off the blocks, sprinting down a trail, or just bouncing around at the gym, these headphones stay in place. They’re lightweight enough that you barely notice them after a while, and there’s no discomfort even after wearing them for an extended period.

Controls are pretty straightforward—volume up and down, track skip, mode switch, all handled with physical buttons. They’re easy to use even with wet hands or while on the move. No fumbling around with tiny touch controls here.

Should You Buy Them?

If you’re looking for a pair of headphones that you can take anywhere—literally, even underwater—the Nank Runner Diver2 Pro is worth checking out.

They’re perfect for swimmers, hikers, runners, and anyone who needs a set of headphones that can handle a bit of everything.

The bone conduction tech isn’t for everyone, especially if you’re a bass junkie, but for most people who want comfort, durability, and versatility, these get the job done.

For the price, they offer a lot of value, especially with the waterproofing and built-in storage. If you’re tired of your regular earbuds falling out or dying on you halfway through a workout, the Nank Runner Diver2 Pro might be just what you need.
