Shokz OpenRun Pro 2
Bone conduction (neckband)8.5 /10The bone conduction pick for most people: the neckband stays put through anything, 12 hours of battery, and Shokz's DualPitch driver adds an air-conduction unit for bass the older models can't make.

The verdict
What's the same
The fit. All three are titanium neckbands with the transducers on the cheekbones, sold in Standard and Mini. Multipoint on all three. Physical buttons on all three. On fit security they tie at 10, and on awareness they tie at 10, so the decision lives in the other 60% of the rubric.
1. Water: IP55 vs IP67
The Pro 2 is IP55; the OpenRun and Air 2 are IP67. Shokz's comparison post spells out the practical difference: the OpenRun is “fully washable under the tap,” Pro models get “gentle cleaning with a damp cloth.” Neither IP67 model is rated for swimming (Shokz says “not for swimming” beside the Air 2's rating). If your problem is dried salt on the pads or a downpour, the 67s are built for it. The Pro 2 scores 8 on sweat resistance; the other two score 10.
2. Sound: DualPitch vs single-path
The Pro 2's 10th-gen DualPitch pairs the bone transducer with an air-conduction unit. The Air 2 uses PremiumPitch 3.0 (8.5-gen) and the OpenRun PremiumPitch 2.0+ (8th-gen), both bone-only. Shokz's own post describes the Pro 2 as music-focused and the Air 2 as lightweight-focused. On our rubric that's 6 versus 5 versus 4. None has real bass; the Pro 2 has the most.
3. Battery and charging
12 hours (Pro 2), 10 (Air 2), 8 (OpenRun). Quick charge: 5 minutes for 2.5 hours, 5 for 2, 10 for 1.5. The Pro 2 and Air 2 charge over USB-C in an hour. The OpenRun uses a magnetic induction cable on most colors (USB-C on blue and black only, per Shokz) and takes 1.5 hours. Losing the proprietary cable is the single most common OpenRun complaint we read, and it's the reason we say buy it only on a deal.
4. Weight and Bluetooth
26.4 g for both the Air 2 and OpenRun; 30.3 g for the Pro 2. Shokz says the Air 2's frame is 9% smaller than the OpenRun's. Bluetooth 6.0 (Air 2), 5.3 (Pro 2), 5.1 (OpenRun). Four grams on a neckband is noticeable over a marathon and not over a 5K.
5. Where that leaves the OpenRun
It's the pair most runners you know are wearing, it's IP67 and it has a moisture detector. It's also 2019 hardware with 8 hours and a magnetic cable at the same list price as the Air 2. Shokz keeps selling it because it still works; buy it when a retailer cuts the price, not at list.

What the spec sheet supports
- Titanium neckband plus ear hooks: nothing to fall out of an ear canal
- 12 hours per charge and a real quick charge, on USB-C instead of a proprietary cable
- DualPitch adds an air-conduction driver, so bass exists where older bone conduction sets had none
- Wind-resistant dual mics rated to 25 km/h for calls on the move
Where it falls short
- IP55, not IP67 like the cheaper OpenRun and OpenRun Air 2: fine for sweat, not for rinsing under a tap
- Bone conduction still leaks at high volume in a quiet room
- The most expensive of the three OpenRun models
Skip this if…
…you want to rinse the headphones under a tap after a soaked run (get the IP67 OpenRun Air 2) or you train mostly indoors where a sealed earbud's bass would matter more than an open ear.

What the spec sheet supports

- Lightest current Shokz neckband; Shokz says the frame is 9% smaller than the OpenRun's
- USB-C charging and a 5-minute quick charge
- Bluetooth 6.0 with multipoint
Where it falls short
- No DualPitch air-conduction unit, so bass is thinner than the Pro 2
- Two hours less battery than the Pro 2
- Bone conduction leakage and cheekbone buzz at high volume, like every neckband here
Skip this if…
…sound quality is the reason you'd spend more (the Pro 2's DualPitch is audibly fuller) or you need the Pro 2's 12-hour battery for ultra-distance days.

How we scored this
Pairs we claim to have worn: none we haven't
Plenty of sites say they ran a hundred miles in every pair on the list. We don't say that, and we say so on every page. What we do instead: classify the retention system (hook, clip, wing, neckband), record the maker's published IP rating, weight, battery, charging, mic and control type from its own product page, cross-reference at least one independent published review where one exists, and score every pick on a public rubric. Every figure links to where it came from.
Scores are editorial judgments from that documented research, not lab results. Commissions never set a score or decide a pick. The rubric and its weights are published.
