If you want a polished everyday training headphone with app-tuned EQ modes and strong call clarity, choose Shokz OpenRun Pro 2; if you need a fully waterproof headset that plays music from built-in storage while you swim, choose SONR Bone Conduction Waterproof.
Both are open-ear bone conduction designs, which means both keep your ear canals uncovered so you can hear traffic, training partners and gym announcements. That shared trait is the whole reason people shop this category. The split comes down to what happens after the run ends: one is built around Bluetooth audio and app control, the other is built around a 32GB player you can take underwater.
• Shokz OpenRun Pro 2 — biggest strength: a hybrid dual-driver setup that pairs bone conduction highs with air conduction bass, plus dedicated EQ modes in the Shokz App and a 12-hour battery.
• Shokz OpenRun Pro 2 — biggest trade-off: it is a Bluetooth headphone with no on-board music storage, so it cannot be used as a standalone player in the pool.
• SONR Bone Conduction Waterproof — biggest strength: IPX8 waterproofing combined with 32GB of built-in storage (29GB usable), so you can swim with music and no phone.
• SONR Bone Conduction Waterproof — biggest trade-off: an 8-hour battery and a single bone conduction driver, with button controls rather than an app.
• Pick Shokz OpenRun Pro 2 if your training is mostly on land and you care about sound tuning, calls and battery life.
• Pick SONR Bone Conduction Waterproof if swimming or triathlon is central to your routine and you want phone-free audio in the water.
The OpenRun Pro 2 is the more "connected" of the two. Its headline feature is a hybrid driver design — bone conduction handles the upper frequencies while an air conduction element adds bass, which is the usual weak point of bone conduction audio. Shokz brands this DualPitch, and the stated frequency range runs from 20Hz to 20,000Hz. In practice that means a fuller low end than a pure bone conduction driver typically delivers, which matters for anyone who finds open-ear sound thin.
Fit is handled by a unibody frame with ergonomic ear hooks and a nickel-titanium alloy memory wire, and the whole thing weighs about 0.3 kg with the packaging. Battery life is rated at 12 hours. The trade-offs are straightforward: no music storage on board, Bluetooth 5 wireless only, and the waterproofing claim isn't stated as an IPX rating here — this is a land-training headphone, not a swimmer's tool. Note too that this listing is a renewed unit carrying a 90-day limited warranty, which is worth factoring in if long-term coverage matters to you.
Buy it if you run, cycle or lift, want app-level control over your sound, and value call quality and a long battery. Skip it if you swim laps and want your music to come from the headphones themselves.
SONR Bone Conduction Waterproof: Who It's For
The SONR is built around one idea: take your music underwater without a phone. It carries 32GB of total storage with 29GB usable, and it plays that audio in MP3 mode over a USB upload. For a swimmer, that changes the entire proposition — no phone on the pool deck, no Bluetooth signal dying the moment your wrist goes under, just continuous audio for your whole set.
The IPX8 rating is the other half of that story. IPX8 means the headset is engineered to survive continuous immersion, and SONR positions it for underwater swimming, triathlon training, running, cycling, gym sessions and outdoor work. If your week includes both pool sessions and road runs, the dual Bluetooth and MP3 modes let you switch: stream from your phone on dry land, flip to stored audio in the water. A built-in microphone handles calls during dry-land workouts, though bone conduction mics near water are best thought of as a land feature.
Where it gives ground is audio sophistication and endurance. It uses a single bone conduction driver, with no hybrid bass element and no app-based EQ. Controls are physical buttons rather than an app. Battery life is rated at 8 hours, which is generous for a multisport headset but shorter than the Shokz figure. The frame is a lightweight plastic wrap-around design, and the warranty is one year.
Side-by-Side: Which Should You Choose?
• Best for aware mode and open-ear safety → both. Neither covers your ears, so both keep you aware of traffic and surroundings. This is the category's core benefit, and it's a tie.
• Best for battery life → Shokz OpenRun Pro 2. 12 hours versus 8 hours.
• Best for swimming and triathlon → SONR Bone Conduction Waterproof. IPX8 plus 32GB of built-in storage is the decisive combination.
• Best for sound tuning → Shokz OpenRun Pro 2. Hybrid dual drivers plus Classic and Volume Boost EQ modes in the app.
• Best for phone-free listening → SONR Bone Conduction Waterproof. 29GB usable storage means no phone required at all.
• Best for calls → Shokz OpenRun Pro 2. Dual wind-resistant mics with AI noise reduction rated to cut 96.5% of background noise.
• Best for simple controls → SONR Bone Conduction Waterproof. Physical buttons, no app pairing needed.
• Best for warranty coverage → SONR Bone Conduction Waterproof. One year versus 90 days limited on the renewed Shokz unit.
In my opinion, most people shopping this comparison should buy the Shokz OpenRun Pro 2. The hybrid driver design, the EQ modes, the 12-hour battery and the noise-reduction spec on calls make it the stronger all-round headphone for land training, commuting and gym work — the situations where you'll actually wear these most days.
I'd only steer you to the SONR if swimming is genuinely part of your routine. If it is, the IPX8 rating and 32GB of on-board storage aren't nice-to-haves, they're the reason to buy it, and no amount of app tuning on the Shokz replaces them. Decide which of those two lives you actually live, then check the current price on Amazon before you commit.
Ambient aware (or awareness) mode uses microphones to pipe outside sound into your ears so you stay alert to your surroundings. Bone conduction headphones like these two achieve the same goal differently — by leaving your ear canals completely open, so you hear the world naturally without any electronics involved.
On Bose models this is usually a button press or a toggle in the Bose app that cycles between Quiet and Aware modes. It's worth noting that neither headphone here needs that step: the Shokz OpenRun Pro 2 and SONR are open-ear by design, so awareness is always on by default.
JLab typically handles this through a button combination or its app's ambient control. The concept doesn't apply to either headphone in this comparison, because there's no sealed earcup to switch between modes — your ears stay open the entire time.
The SONR Bone Conduction Waterproof does — it carries an IPX8 rating and 32GB of storage so you can swim with stored music and no phone. The Shokz OpenRun Pro 2 is positioned for land training, so treat it as a dry-land headphone rather than a swim device.
