What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Nank Runner Diver2 Pro
Only one whitelisted tester, TechRadar, published a hands-on review of this exact model (Senior Fitness Editor Matt Evans, month-long test). It praised the IP69 waterproofing, 32GB onboard storage (~8,000 tracks) and long battery life, while faulting the weak noise-canceling mode and dated USB-A charging. (1 sourced review, 1 lab-tested.)
Praised: Fully waterproof/sweatproof (IP69), works well in the pool; Huge 32GB onboard storage (~8,000 tracks) for phone-free swims/runs; Long battery life (~12 days mixed use) plus fast charging.
Flagged: Noise-canceling mode disappoints — makes music louder, not clearer, with sound leakage; Dated USB-A charging despite premium price; Expensive at full price ($199.99); carry case sold separately.
Creative Outlier Free Pro
Only one whitelisted hands-on review exists: Tom's Guide (July 2023), which tested the Free Pro over a week. It found comfortable, versatile, swim-friendly bone-conduction headphones at a low price, but second-tier, muddy sound and battery that falls short of the rated 10 hours at loud volume. Every finding below is therefore single-source. (1 sourced review, 1 lab-tested.)
Praised: Light and comfortable for long-term wear; Versatile: Bluetooth streaming plus 8GB onboard MP3 player for IPX8 pool swims; Affordable; cheaper than Shokz OpenSwim / Naenka Runner Diver.
Flagged: Bone-conduction sound not best-in-class — muddy bass, boxy mids, grainy treble; Battery falls short of the rated 10 hours at higher volumes; Mediocre call quality from a single mic, plus typical sound leakage.
