7 Myths About Wireless Earbuds You Should Stop Believing

7 Myths About Wireless Earbuds You Should Stop Believing

Some beliefs about wireless earbuds have been circulating for years without ever really being questioned.

Here are seven of them, explained and corrected.

1. "You should fully drain the battery from time to time"

False for today's lithium-ion batteries.

This practice made sense for older technologies (NiMH), not for the batteries used in earbuds today, which actually prefer partial charge cycles.

2. "A higher price guarantees better sound"

Not necessarily.

Price also reflects marketing, licensing, and the manufacturer's margin — see our article on the link between price and quality.

3. "ANC blocks out all outside noise"

No.

ANC is noticeably more effective on low, continuous noise than on voices or high, irregular sounds — a physical limitation of the technology, not a design flaw.

4. "A newer codec automatically sounds better"

Not always.

A more capable codec offers better technical specs, but the actual sound also depends on the driver, the DAC, and the acoustic tuning chosen by the manufacturer.

5. "More microphones always means better call quality"

Not necessarily.

The number of microphones matters less than their placement and the signal processing applied afterward — two models with the same mic count can sound very different on calls.

6. "The advertised battery life matches what you get in real use"

Rarely exactly.

Advertised figures are measured under standardized conditions (moderate volume, ANC often off) that don't consistently reflect everyday use.

7. "All water-resistant earbuds can be safely submerged"

No.

Most resistance ratings cover sweat and splashes, not deliberate prolonged submersion, even at high IP ratings.

FAQ

Do these myths apply across all price ranges?

Yes, they apply regardless of budget.

A premium model can be just as affected by unrealistic expectations based on these beliefs as a budget one.

Why do these myths stick around so much?

Many come from older technologies (NiMH batteries) or oversimplified marketing shortcuts, repeated over time without ever being questioned.

Where can I find more reliable information before buying?

Comparing concrete technical specs rather than marketing slogans remains the most reliable approach — that's exactly what the Finder is for.

Conclusion

Most of these myths trace back to older technologies or marketing shortcuts that turned into habits nobody ever really questioned.

None of them are tied to budget — a premium model can be just as exposed to them as a budget one.
