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.
Haylou PurFree BC01
Two whitelisted hands-on testers (TechRadar, July 2022; Tom's Guide, June 2023) reviewed the Haylou PurFree BC01. Both rate it excellent value versus Shokz, with balanced, pleasant bone-conduction sound, a comfortable secure ~28g fit, clear calls via dual-mic noise reduction, and solid ~8-hour battery with a 10-minute fast charge. Neither ran lab benchmarks; the only hard figures verified in-text are TechRadar's 60cm charging cable and Tom's Guide's 8-hour battery and 1.5-hour full charge. Tom's Guide flags noticeable sound leakage in quiet spaces, and the two disagree on controls. (2 sourced reviews, 2 lab-tested.)
Praised: Great value for the price versus Shokz; Balanced, pleasant sound for bone conduction; Comfortable, secure, lightweight fit (~28g).
Flagged: Noticeable sound leakage in quiet spaces; Proprietary (non-USB-C) magnetic charging cable; Unintuitive multi-tap control gestures.
