• SHOKZ OpenRun Pro 2 — biggest strength: a dual-driver setup that pairs a bone conduction driver with an air conduction driver for deeper bass, plus app-based EQ modes and dual wind-resistant mics that filter up to 96.5% of background noise.
• SHOKZ OpenRun Pro 2 — biggest trade-off: IP55 is splash and sweat resistant, not fully dust-tight or water-submersion rated, and it charges in a slower 60 minutes.
• Plufunex Bone Conduction Headphones — biggest strength: IP68 sweat and rain resistance, a light 32g build, Bluetooth 6.0 multipoint and a 10-minute magnetic charge that yields up to 75 minutes of listening.
• Plufunex Bone Conduction Headphones — biggest trade-off: a single 16mm bone conduction driver, no noise control and just a 1-year warranty, so it's the simpler audio package.
• Who each is for: pick the SHOKZ for richer sound, clearer calls and app tuning; pick the Plufunex for wet-weather training, glasses-friendly comfort and easy device switching.
The OpenRun Pro 2 is the more ambitious of the two on the audio side. Instead of relying on bone conduction alone, it combines a bone conduction driver with an air conduction driver, and the payoff is meant to be fuller bass under the clear highs. The frequency range is stated at 20 Hz to 20,000 Hz, so the low end is part of the design story rather than an afterthought. If you run or lift to music and you actually notice when bass goes missing, this is the model built with that complaint in mind.
What makes it feel like a serious training tool is the software layer. The Shokz App gives you dedicated EQ modes — a Classic Mode for pure bone conduction sound and a Volume Boost Mode for noisy environments — and you can also switch modes on the unit by holding the Power/Volume + and Volume – buttons until you hear a beep. The dual wind-resistant microphones with AI noise reduction claim to cut 96.5% of background noise, including wind up to 15 mph, which matters if you take calls mid-ride. The unibody frame uses a Ni-Ti alloy memory wire with ergonomic ear hooks for a stable fit, the whole thing weighs 30.3 g, and it runs about 12 hours on a 60-minute charge. It ships with a hard shell carrying case and a reflective strip, and it carries a 2-year warranty.
Should you skip it? If your workouts are consistently soaked — heavy rain, hose-downs, gritty trail spray — the IP55 rating is the weak point. It handles sweat and splashes, not immersion. And if you want the fastest possible top-up before a session, the full hour charge is slower than the Plufunex alternative. Also worth knowing: there's no headphone jack, so it's Bluetooth-only, with a stated 33-foot range on Bluetooth 5.3.
The Plufunex pair is aimed squarely at people who put weather and fit ahead of audio refinement. Its headline spec is IP68 — sweat and rain resistant, built for unpredictable conditions. The manufacturer is explicit that it's not intended for underwater swimming or water immersion, so treat it as a rain-and-sweat champion, not a swim headset. For runners and cyclists who train through drizzle and don't want to think about their gear, that's a meaningful difference in how you use them day to day.
The fit story is where Plufunex has clearly done its homework. It's a 32g wraparound with a stable ear-hook structure and 35° adjustable ear hooks to dial in fit and cut wind interference. More interestingly, it's explicitly engineered to sit comfortably with everyday glasses, prescription glasses, cycling eyewear and even smart glasses — a real consideration if you ride with shades or need correction. Controls are physical buttons giving instant tactile feedback, which is genuinely useful with sweaty hands mid-workout, and there are no touch controls to misfire.
On the tech side you get Bluetooth 6.0 with multipoint, so you can pair a laptop and a phone at once and switch between them without re-pairing. Battery is listed at 13 hours, with a 10-minute magnetic charge delivering up to 75 minutes of listening — handy when you've forgotten to plug in. The driver is a single 16mm bone conduction unit at 91 dB sensitivity, and there's no noise control. Warranty is 1 year. If you want app-based EQ tuning or premium bass, that's simply not what this model is selling.
Side-by-Side: Which Should You Choose?
• Best sound quality → SHOKZ OpenRun Pro 2. Dual drivers (bone + air conduction) and app EQ modes give it the richer, more tunable audio.
• Best for wet weather and hard training → Plufunex Bone Conduction Headphones. IP68 beats IP55 when rain and heavy sweat are the norm.
• Best for calls → SHOKZ OpenRun Pro 2. Dual wind-resistant mics with AI noise reduction claim to filter 96.5% of background noise, including wind up to 15 mph.
• Best for battery life → Plufunex Bone Conduction Headphones. 13 hours versus 12, plus a 10-minute charge for up to 75 minutes of playback.
• Best for quick top-ups → Plufunex Bone Conduction Headphones. A 10-minute magnetic charge is far more convenient than a 60-minute full charge.
• Best for switching between devices → Plufunex Bone Conduction Headphones. Bluetooth 6.0 multipoint lets you run two devices at once.
• Best for long-term peace of mind → SHOKZ OpenRun Pro 2. A 2-year warranty and a hard shell carrying case add up to better long-haul value.
• Lightest on the head → Plufunex Bone Conduction Headphones. 32g versus 30.3g is close, but the adjustable 35° hooks make the Plufunex easier to fine-tune.
In my opinion, the SHOKZ OpenRun Pro 2 is the better buy for most people who care about how their music sounds. The dual-driver design, the Classic and Volume Boost EQ modes, the call-clarity mics and the 2-year warranty make it the more complete product for running, cycling and gym work in normal conditions. I'd only steer you to the Plufunex if IP68 rain resistance, glasses-friendly comfort or Bluetooth 6.0 multipoint are your deal-breakers — those are real advantages, and it's the smarter pick for wet-weather athletes on a tighter budget. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision.
FAQ
For audio quality, EQ control and call clarity, yes — the dual-driver design and dual noise-reducing mics give it the edge. For waterproofing and fast charging, the Plufunex wins.
They carry an IP68 rating for sweat and rain resistance, but the manufacturer states they're not intended for underwater swimming or water immersion. Treat them as rain-ready, not swim-ready.
The Plufunex is listed at up to 13 hours versus about 12 hours for the SHOKZ. The bigger practical gap is charging: the Plufunex gets up to 75 minutes of playback from a 10-minute charge, while the SHOKZ needs about 60 minutes for a full charge.
Yes — they're specifically engineered to fit comfortably with everyday, prescription, cycling, sports and smart glasses without pressure points. That's one of their clearest design advantages over the SHOKZ.
