At a Glance: The Verdict
| Shokz OpenRun Pro 2 | Suunto Aqua |
|---|---|
|
Best For: Road runners and gym-goers who want the ears open Lighter, longer battery, and the better speaker and mic combo. It pipes music through your cheekbones while leaving your ears free to hear traffic. This is the daily-driver open-ear headphone for people who run on pavement. |
Best For: Swimmers who want music in the pool without a phone Fully submersible to 5m with 32GB of onboard storage, so it plays MP3s underwater where Bluetooth signals die. The only pick here if your main sport is swimming, but overkill and heavier for dry-land running. |

Both of these are bone-conduction, open-ear headphones that clip around the back of your neck, and both land right around $180. But they are built for two different pools of water, literally. One is a road-running headphone. The other is a swimming headphone that happens to work on land.
Key Differences
- Water resistance: The Suunto Aqua is swim-safe (IP68, rated to 5m for 2 hours). The Shokz OpenRun Pro 2 is sweat and rain resistant only (IP55). Do not swim with the Shokz.
- Onboard storage: The Aqua has 32GB of built-in MP3 storage so it plays music with no phone. The OpenRun Pro 2 has no storage and always needs a Bluetooth source.
- Weight and battery: The Shokz is lighter (30.3g vs 35g) and lasts longer (12 hours vs 10 hours per charge).
- Bluetooth: The Aqua runs Bluetooth 5.4; the Shokz runs 5.3. A minor edge on paper, not something you will feel on a run.
- Sound and calls: The Shokz pairs a bone-conduction transducer with an actual air-conduction speaker plus dual mics, which makes it the stronger choice for music richness and phone calls.
Deep Dive Comparison
Sound & Mic
The OpenRun Pro 2 is the clear winner for audio. Shokz added a dedicated air-conduction speaker alongside the bone-conduction transducer, so you get real low-end punch that most open-ear headphones just cannot produce. Bass actually shows up. Its dual-microphone setup also handles calls on the move far better, cutting wind and road noise so the person on the other end can hear you.
The Suunto Aqua puts its priorities elsewhere. Its bone-conduction sound is clear and perfectly fine for podcasts and playlists, but it is tuned to survive underwater, not to win a bass shootout on dry land. If a big chunk of your listening is phone calls or bass-heavy music while running, the Shokz is the pick.
Situational Awareness
This is the whole reason open-ear exists, and both nail it because neither one plugs your ear canal. On the OpenRun Pro 2 you hear cars, cyclists, and other runners with zero effort, which is exactly what you want on a busy street or a shared trail. It is one of the safest ways to run with audio.
The Aqua is just as open in the air, but its awareness superpower is in the water: your ears stay clear so you can still hear a coach on the deck or a swimmer in the next lane. For pure road-awareness on a run, they are effectively a tie. For pool awareness, only the Aqua is in the conversation.
Fit & Comfort
The Shokz is the more comfortable long-run companion. At 30.3g with a titanium band, it disappears on your head, and the wraparound design stays locked during sprints and hill repeats. It plays nicely with glasses and hats because nothing sits inside or over your ear.
The Aqua is heavier at 35g, and that extra mass is the tradeoff for a sealed, submersible body. It still holds tight enough for swimming, which needs an even more secure grip than running. But for a two-hour long run, the lighter Shokz is the one you will forget you are wearing.
Battery & Charging
The OpenRun Pro 2 rates 12 hours of listening per charge; the Aqua rates 10 hours. Two hours is a real gap if you like to charge once a week and forget about it, and it lines up with the Shokz being the more running-focused daily driver. Both cover any single session you will realistically do, run or swim.
Durability & Water Resistance
This is the single most important line in the whole comparison. The Suunto Aqua carries an IP68 rating, verified to 5m depth for 2 hours, so it is genuinely swim-safe for pool and open water. The Shokz OpenRun Pro 2 is IP55, which means it shrugs off sweat, splashes, and rain but is NOT built for submersion. Do not take the Shokz into the pool. If swimming is on your list, the Aqua is not just better here, it is the only option that qualifies.
Connectivity & Smart Features
The Aqua’s headline feature is that 32GB of onboard storage. Load it with MP3s and it plays with no phone at all, which is the entire point underwater since Bluetooth does not travel through water. Its motion sensors also log swim-form data like stroke posture, head pitch, breath frequency, glide time, and a neck-fatigue and jump-test readout, so it doubles as a swim coaching tool. It runs Bluetooth 5.4.
The OpenRun Pro 2 keeps it simpler: Bluetooth 5.3, no onboard storage, and physical buttons for volume and playback. It leans on your phone for music, which is no burden on a run where your phone is usually with you anyway.
Price & Value
Pricing is basically a wash. The Shokz OpenRun Pro 2 launched at $179.95 and the Suunto Aqua at $179. So value is not about the number, it is about the sport. Spend your $179 on the Shokz and you get the best open-ear running headphone with better sound, a better mic, more battery, and less weight. Spend the same $179 on the Aqua and you are paying for waterproofing and onboard storage that a dry-land runner will never use. Match the tool to the water.

The Verdict
These headphones barely compete. They just happen to look alike and cost the same. Pick by where you sweat.
Buy the Shokz OpenRun Pro 2 if you run, walk, or lift on dry land. It is lighter, lasts two hours longer, has the better speaker and the better mic, and keeps your ears fully open for traffic. For the large majority of buyers, which means runners and gym-goers, this is the better headphone, full stop.
Buy the Suunto Aqua only if swimming is a real part of your training. The IP68 waterproofing and 32GB of onboard storage let you play music underwater with no phone, and nothing the Shokz does can match that. But if you never get in the pool, you are paying $179 for waterproofing you will never touch while giving up battery, sound, and lightness. Match the headphone to the water and the choice makes itself.
Frequently Asked Questions
Which one should I buy for running?
The Shokz OpenRun Pro 2, without hesitation. It is lighter at 30.3g, lasts 12 hours per charge, has a stronger speaker and mic, and keeps your ears open for traffic. The Suunto Aqua’s waterproofing is dead weight if you never swim.
Can I swim with the Shokz OpenRun Pro 2?
No. The OpenRun Pro 2 is rated IP55, which covers sweat, splashes, and rain but not submersion. If you want music while swimming, the Suunto Aqua’s IP68 rating (5m for 2 hours) is the one built for it.
Why does the Suunto Aqua have onboard storage and the Shokz doesn’t?
Because Bluetooth does not travel through water, so a swim headphone has to store music on the device itself. The Aqua’s 32GB holds your MP3s and plays them underwater with no phone. The Shokz always streams from a paired phone, which is fine on land but useless in a pool.
Are these worth $179, or is one a better value?
Both launched around $179, so value comes down to your sport, not the price. For runners the Shokz is the better deal because every dollar goes toward sound, battery, and comfort. For swimmers the Aqua is worth it because it is the only one that works in the water at all.
Do these work with both iPhone and Android?
Yes. Both pair over standard Bluetooth (5.3 on the Shokz, 5.4 on the Aqua) and work with any iPhone or Android phone. The Aqua can also run fully offline from its onboard storage, so it does not even need a phone once your music is loaded.
