Conclusion: The NW-E005F is tiny and feather-light, has a built-in FM tuner, and supports lots of audio formats, but I'm not crazy about its buttons, interface, or annoying audio shortcomings.
Pros: Very small and light. Good-quality earbuds included. Long battery life. Fast charging time. Integrated USB plug.
Cons: Audio glitch makes some music sound distorted and grainy. Button layout and size can cause difficult navigation for some users. No PlaysForSure support. No on-device playlist creating or editing.
