Choose comfort first
Use headphones that fit without pressure and that do not cause heat or pain. Over-ear, on-ear, and earbuds can all change the listening experience; the best option is the one you can use comfortably at a modest volume.
Keep volume conservative
Do not turn the audio up to chase a stronger effect. If you notice ringing, discomfort, headache, or dizziness, stop the session. Give your ears a break and seek advice if symptoms persist.
Keep your surroundings in mind
Do not use noise-cancelling headphones while driving or in any setting where you need to hear alarms, traffic, or other people. A wellness routine should not create a safety problem.
Technical limits
Headphones can deliver left and right channels separately, but they cannot make an undisclosed recording transparent. If the product does not publish its exact frequency or waveform, the listener cannot independently compare it with a specific laboratory protocol.
