## What reviewers say

**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.)

**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.)
