Shokz OpenRun Pro 2 review: the bone conduction headphone with bass, and the rating you should know about

What this review is based on

Shokz's official comparison table, its OpenRun Pro 2 product page (for sizing) and its own three-way comparison post, all read September 21, 2026, plus SoundGuys' bone conduction roundup for an independent view of the category's sound. We haven't worn it. The rubric is at How We Rank.

Who it's for, and who should skip it

For: runners and cyclists who want their ears open and their headphones immovable; people whose earbuds fall out; people who take calls at a jog; anyone who found older bone conduction too thin.

Skip: swimmers (IP55; the OpenSwim Pro is the Shokz for that), people who wash their gear (the Air 2 and OpenRun are IP67 and Shokz calls the OpenRun tap-washable), and anyone buying for bass.

Fit, sizes and weight

The OpenRun Pro 2 is a titanium neckband: two transducer pads that rest on the cheekbones just in front of the ears, hooks that sit over the ears, and a band around the back of the head. Shokz lists it at 30.3 g (Standard) or 30 g (Mini), with Standard for head circumference over 9.25 in / 23.5 cm and Mini for under. On our rubric a neckband scores 10 for fit security: nothing in the canal, nothing to rotate on the rim, the whole thing held by the shape of your skull. It is heavier than the OpenRun and Air 2 (26.4 g), and the extra grams sit at the transducers where the DualPitch air driver lives.

IP55: what it covers and what it doesn't

DualPitch and what bone conduction sounds like

Classic bone conduction moves your cheekbone. That reproduces voices and midrange well and low bass badly; SoundGuys' roundup says bone conduction's “sub-bass and bass are virtually inaudible.” DualPitch, Shokz's 10th-generation system, pairs the bone transducer with a small air-conduction unit that pushes sound toward the canal from outside, the same idea as an open-ear hook. Shokz's own comparison post describes the result as music-focused against the Air 2's lighter frame. We score it 6 for sound, two points above the single-path OpenRun and Air 2, and well below any sealed earbud. That's the honest ceiling of the category, and the Pro 2 sits at it. What it sounds like, in plainer terms, is in do bone conduction headphones sound good.

Battery, charging, Bluetooth

12 hours per charge, the longest in the OpenRun family. A 5-minute charge is good for 2.5 hours; a full charge takes an hour over USB-C, which replaces the magnetic cable of the older OpenRun. Bluetooth 5.3, 33 ft range, multipoint, six EQ presets plus two custom in the Shokz app, and a Classic Mode that turns off the air driver for bone-conduction-only listening (Shokz's product page lists it).

Calls and wind

Dual AI noise-canceling mics, “Wind-Resistant (Up to 25 km/h)” in Shokz's table. That rating appears on only three Shokz products, and it's the reason the Pro 2 leads our bone conduction for calls list among the non-boom designs.

Against the OpenRun Air 2

The Air 2 is 4 g lighter, IP67, Bluetooth 6.0, two hours shorter, and single-path bone conduction. Same wind-resistant mics, same USB-C. If sound matters, Pro 2. If you sweat hard or want to rinse, Air 2. Shokz says the Air 2's frame is 9% smaller than the OpenRun's.
