Evaluated over: 3 weeks
Bottom Line

The Shokz OpenSwim emerge as a specialized choice for swimmers, boasting an IP68 waterproof build and a lightweight design that harmonizes with other swimming gears. Their dual listening modes cater to both underwater and terrestrial use, augmented by a 4 GB in-built MP3 player. However, they exhibit certain drawbacks like the absence of a visible battery indicator, a fit that might slacken during vigorous swimming, and no Bluetooth functionality. Primarily stellar for aquatic use, they falter slightly on land, especially for bass-intense music, though they maintain their unique niche appeal.

We bought the Shokz OpenSwim for the purpose of this review.

Formerly known as the Aftershokz Xtrainer, the Shokz OpenSwim have already made a mark on their unique aquatic audio market. They combine bone conduction technology with a high IP68 waterproof rating, promising to be a robust companion for both leisurely and intense aquatic activities.

With a focus not on conventional audio delivery but on enhancing the swimming experience, the OpenSwim steps away from the norm. This raises a compelling question: how effectively does Shokz balance the unique demands of underwater audio with the expected clarity and comfort of high-quality headphones?

To answer this, I tested these headphones for three weeks and brought them into my regular swimming sessions on our community lap pool. Here’s what I found out:

The Shokz OpenSwim headphones, boasting an IP68 rating, have proven to be a reliable companion for aquatic enthusiasts. Based on their IP rating, these headphones are fully protected against dust and any solid particles. They are also well-suited for use in typical swimming environments, such as lap swimming in Olympic-sized pools with an average depth of around 2 meters.

During my swimming sessions, the waterproofing of the Shokz OpenSwim proved to be impressive. The construction of the headset, lacking any visible holes or gaps, instills confidence in its ability to resist water ingress. This smooth design ensures that water seepage is not a concern, even during extended use in the pool.

I rigorously tested these headphones to gauge their durability and reliability underwater. They were submerged at depths of approximately 2 meters for durations of 1-2 hours during my initial swimming session.

During this session, what stood out was their consistent performance, irrespective of the depth and duration. Whether at 1 meter or 2 meters, for an hour or two, the Shokz OpenSwim maintained a steady performance level, showing no signs of water damage or functional decline.

Sound Quality

The Shokz OpenSwim headphones, with their 7th generation bone conduction technology, offer a nuanced sound experience both in and out of the water using their two listening modes: General and Swimming.

In the General mode, tailored for above-ground use, the headphones present a satisfactory bass that’s noticeable without being overpowering. This mode is particularly favorable for genres like indie music, where the balance between bass, midrange, and treble creates a pleasant listening experience.

However, bass-heavy genres like EDM or heavy metal might not sound as appealing, as the lower frequencies tend to become a bit muddy, especially if this mode is used underwater.

Switching to Swimming mode, intended for underwater use, the audio profile changes significantly. The bass and midrange are noticeably reduced, a design choice aimed to prevent a muddy mix underwater.

This mode emphasizes treble and high notes for clarity, making it ideal for underwater listening but not as suitable for above-ground use due to the lack of depth in bass and midrange.

The inclusion of earplugs plays a vital role in maintaining consistent sound quality underwater, compensating for the varying head movements and positions associated with different swimming styles. Without the earplugs, the sound becomes inconsistent and muffled, regardless of the chosen mode.

Interestingly, I didn’t need much volume adjustments underwater. A volume level of 70-80% is already generally sufficient for clear and enjoyable listening. Lower volumes, on the other hand, tend to result in muffled sound, likely due to water pressure.


Featuring a wraparound, behind-the-neck design, the Shokz OpenSwim headphones are astoundingly comfortable to wear, especially during extended swimming sessions. I tested these while swimming for over two hours and didn’t feel any discomfort.

The headphones felt almost non-existent, blending seamlessly into my activity without causing any distraction. This invisibility of sorts is primarily due to their lightweight material, which ensures that they don’t weigh down or create pressure points around the ears or neck.

However, it’s worth noting that the experience slightly shifts when you’re out of the water.

After about 2-3 hours of wearing them above ground, I did start to feel a bit of irritation where the headphones sling behind my neck. This discomfort wasn’t overwhelming but was noticeable, particularly for someone like me who isn’t accustomed to this specific style of headphones.

The Shokz OpenSwim headphones excel in fitting seamlessly with standard swimming gear, such as caps and goggles. I encountered no issues of interference or discomfort, indicating a thoughtful design for aquatic use.

Their around-the-neck style significantly also enhances stability and reduces the risk of the headphones falling off, an advantage over traditional earbud-style headsets.

The slight wobble noticed on land is absent underwater, further emphasizing their stability in their intended environment.

Plus, as I experimented with different swimming strokes and increased my pace, the headphones adapted well, particularly at lower to medium intensities.

Sure, there was a slight loosening when I pushed to a higher pace, but I found a simple fix by securing the top part of the headset with my swimming cap. While this might affect comfort for some, it didn’t bother me much and seemed a small compromise for the stability it provided.

Overall, my time with the Shokz OpenSwim headphones was quite positive. Their design, stability, and compatibility with swimming gear make them a solid choice for swimmers who want to enjoy audio in the water without the hassle of constantly adjusting their headphones.

The first thing that struck me in terms of durability was the premium feel of the headphones. The rubberized covering, a common feature in swimming gear, gave it a sense of belonging in the pool environment. This material choice not only contributes to the aesthetic but also plays a vital role in the durability of the product.

The combination of aluminum construction and rubberized exterior also suggests that these headphones can survive numerous falls and rough handling. During my time using them, they felt robust and capable of withstanding the typical wear and tear associated with regular swimming sessions.

I also didn’t noticed any significant signs of deterioration like color fading, cracking, or peeling. However, after prolonged exposure to pool water, I observed some white powdery artifacts, which I suspect might be due to the chlorine. This is something users should be aware of, as it could affect the long-term appearance of the headphones.

I found it best to rinse them off after each pool session to remove chlorine and other pool chemicals, ensuring their longevity.

Maintenance and cleaning of these headphones are remarkably straightforward, which is a huge plus. Post-swim, there’s no need for elaborate cleaning routines. Like many rubberized swimming accessories, they can simply be placed in their pouch, and they’ll dry on their own.


My experience with these headphones aligns well with the manufacturer’s claim of 8 hours of battery life. During my typical 1-2 hour swimming sessions, I found that a single charge lasted for about three sessions, without the need for a recharge in between.

This is quite impressive and indicates that for casual listeners like myself, who can’t use headphones continuously for 8 hours due to work commitments, the OpenSwim can comfortably provide 2-3 days of use.

The charging time for these headphones is another highlight. It takes approximately 2 hours to fully charge, which then translates to 8 hours of usage.

This charging duration, while not too outstanding, fits seamlessly into my routine, as I rarely run out of battery. On the off chance that I do, the ability to quickly charge the headset with a power bank adds a layer of convenience that I appreciate.

Additionally, Shokz has integrated a thoughtful feature to conserve battery life. The headset automatically powers down after an hour of idleness, which is a smart way to preserve the battery when not in active use.

However, one area that could see improvement is the method of informing users about the remaining battery life. Currently, the only indication of a low battery comes from a voice notification when the headset is close to being completely discharged. This means there’s no direct way to check the battery level during a swim, which can be a bit inconvenient.

The notification typically kicks in when there’s about 45 minutes of charge left, urging the user to recharge the device soon.


In terms of intuitiveness, OpenSwim’s controls are straightforward and easy to operate. Adjusting the volume, skipping tracks, or pausing music can be done with minimal effort. This ease of use is crucial when you’re in the middle of a swim and prefer not to stop your flow.

That said, certain functions like enabling the “Shuffle mode” do require a brief pause, as it requires holding down a button for about 5 seconds.

The headphones also offer both shuffle mode and normal mode for playback. The shuffle mode keeps my swimming sessions interesting with a random mix of tracks, while the normal mode plays songs in the order I saved them, allowing me to set a specific mood or pace for my swim.

The controls have also held up remarkably well against constant exposure to water and chlorine. I haven’t noticed any wear or deterioration in the controls over time. I also didn’t encounter any issues like accidental triggers on the controls.

However, there don’t seem to be any special control features specifically tailored for swimmers. Standard controls are provided without additional enhancements for underwater use, which is a missed opportunity for further refinement.

But the most frustrating part is familiarizing myself with the small-sized buttons and their placement. Initially, finding and pressing the correct button can be a bit challenging, especially when you’re focused on your swim. Over time, though, this becomes less of an issue as muscle memory kicks in.

Audio Playback Options

The Shokz OpenSwim headphones’ built-in MP3 player works best for swimmers, as other wireless options like Bluetooth won’t work well underwater.

The good news is, loading music onto the built-in MP3 player of my Shokz OpenSwim headphones is incredibly straightforward and convenient. The drag-and-drop operation for transferring music files is as simple as moving files onto a USB drive.

However, the challenge I faced was primarily about sourcing the actual MP3 files of my favorite songs.

With the dominance of streaming services like Spotify and Apple Music, finding downloadable MP3 files, especially for popular songs, has become more complex due to copyright and piracy concerns. I had to find ways to legally obtain MP3 files (without spending much), which required a bit more effort.

In terms of compatibility, I find that these headphones work well with various devices, such as PCs and Macs. However, I have noticed some difficulty when trying to load music from a mobile phone, which is something to consider if you primarily use your phone for music.

The 4 GB storage capacity of the OpenSwim is quite impressive. Based on my calculations, assuming each MP3 file is about 5MB, this allows me to store roughly 800 songs. This is more than enough for my swimming playlists, ensuring a wide variety of music for my sessions.

As for the playback quality, I haven’t noticed any significant differences between the various supported formats like MP3, WAV, WMA, AAC, and FLAC. The key factor here is the source quality of the audio file. I’ve learned that a bad copy or overly compressed file can greatly affect the song quality, regardless of the format.

Who Should Buy This

The Shokz OpenSwim headset is ideal for casual or recreational swimmers, especially those who engage in long, leisurely swims of 5 kilometers or more. The great waterproofing capacity, along with intuitive controls, comfortability, and decent underwater sound quality, can help make their long swims more enjoyable.

However, those seeking a versatile headset for both swimming and regular on-land use might find the OpenSwim’s lack of features like Bluetooth connectivity limiting for everyday listening needs.

Final Thoughts

As an avid swimmer, my experience with the Shokz OpenSwim headphones was largely positive. Their IP68 rating is a standout feature, guaranteeing complete dustproof and waterproof protection, which gave me peace of mind during my pool sessions.

While swimming, they were remarkably comfortable and light, blending seamlessly with my activities. They fit well with my swimming gear, staying securely in place, particularly when tucked under my swim cap during intense laps.

In essence, for swimmers looking for a dedicated, waterproof audio solution, the Shokz OpenSwim headphones are a solid choice.

However, they are not as great when used outside of the swimming pool. While there’s a General listening mode that offers a decent audio experience on land, the headphones tend to struggle with heavier bass tracks. This becomes particularly noticeable with genres like EDM or heavy metal, where the bass can feel muddy, diluting the overall audio experience.

After a few hours on land, I also started to feel some irritation where the headphones wrapped around my neck. This is a stark contrast to the almost unnoticeable feel they have in the water. Moreover, the lack of features like Bluetooth connectivity restricts their versatility, limiting their appeal for those seeking a multi-environment audio device.
