How many hours can I safely game with a headset each day?

There is no single number for everyone, but modern guidelines suggest keeping total weekly exposure around 80 dB for 40 hours for adults and 75 dB for 40 hours for children and teens across all listening, not just gaming. If you are gaming at moderate volume for a few hours a day and not cranking it at other times, you are likely in a safer range.

Is noise-cancelling good or bad for gamers?

Noise-cancelling is generally helpful when used responsibly. By reducing background noise, active noise cancelling allows you to hear clearly at lower volumes, which reduces your overall sound dose. It should not be used as an excuse to listen at extremely high volumes.

Do I need a hearing test if my ears only ring sometimes after gaming?

Yes. Intermittent ringing after sound exposure is a classic early warning sign of noise stress on the auditory system. A baseline hearing test with an audiologist gives you a reference point so you can catch small changes before they become permanent problems.
