Headphones, binaural tones and guided meditation: what is known

A binaural beat is a pulsing sound you hear when each ear gets a slightly different steady tone. Studies do not agree on what, if anything, it does, and this guide makes no claim about health effects. Good stereo headphones at a moderate volume are the practical part.

What are binaural tones?

If your left ear gets a 200 Hz tone and your right ear gets 204 Hz, you may hear a slow pulse at the difference, 4 Hz. That is only arithmetic and an example, not a recommended setting. The beat you hear depends on each ear receiving only one of the tones. That is why research studies normally use stereo headphones. Through speakers, both ears hear both tones, so you should not expect to hear the same beat.

Stereo itself is simple. A stereo recording has two channels, left and right. Headphones deliver each channel to one ear. A guided voice can sit in the middle, with music or a tone bed spread across both sides. That can feel roomy and close at once.

Why headphones for guided meditation?

Some people find headphones help them settle. They can block some of the room and keep a voice close. Others prefer a speaker, because nothing sits on their ears. Neither choice is wrong.

Choosing and fitting headphones

• Comfort first. You may sit for ten minutes or more. Pressure behind the ear or a tight band will pull your attention away.
• Seal, not squeeze. Over-ear cups should rest lightly around the ear. Earbuds should sit snugly enough to stay put without pushing in hard.
• Left and right matter for tones. Check the small L and R marks. If the sides are swapped, a plain voice session sounds the same, but the left-right sound is reversed.
• Both sides working. Test with a stereo track first. If one side is quiet, fix that before you rely on stereo sound.
• Wired or wireless. Either works. Wireless pairs can drop out, so check the battery before you sit.

Volume: a short routine

The WHO fact sheet on hearing loss says more than a billion young adults are at risk of permanent, avoidable hearing loss from unsafe listening practices. It also describes safe listening strategies. A simple routine:

1. Start with the volume low, before you press play.
2. Raise it until the voice is clear and no more.
3. If someone nearby can hear your headphones, it is too loud.
4. If you cannot hear the room at all, it is too loud.
5. Take a short break after a long session, and keep tones especially quiet. A steady tone can feel soft yet still be played at a high level.

If your ears ring or feel full after listening, stop and rest them.

What studies have found

The evidence is mixed and still developing.

• A 2023 systematic review in PLOS ONE (Ingendoh and colleagues) looked at whether binaural beats really "entrain" brain activity, as is often claimed. Of 14 studies, five matched that idea, eight did not and one was mixed. The 14 studies differed a great deal in method.
• A 2015 review (Chaieb and colleagues) described the field as promising but noted that findings are often contradictory, and looked at why.

These papers also ask different questions. Some test whether brain electrical activity follows the beat. Others look at how people feel or perform. That is another reason the results are hard to compare.

In short, studies use different methods and do not all agree. We make no promise about brain activity, and 2hives does not claim tones do anything beyond sounding the way they sound. Some people enjoy them as a gentle background. Others prefer a plain voice. Both are fine.

A simple way to try it

Pick one short guided session. Listen once with plain voice, then once with a tone bed on another day. Notice which you prefer, and drop what you do not like. There is no right answer. If you want a daily habit, see the 10 minutes a day guide, or look at the challenge, which runs from 21 December 2026 to 19 January 2027. See the challenge page for dates and joining.

Practical tips

• If a tone feels odd or uncomfortable, stop. You can listen to a guided session without tones.
• Do not leave the volume loud and drift off with headphones on. Lower it first.
• Pause or remove a headphone cup when you need to talk or hear around you.

A note on safety

This is relaxation and general information, not medical advice or treatment. Never listen while driving or operating machinery. If you have epilepsy, seizures or a hearing condition, check with a doctor before using audio like this. See the 2hives safety page.

FAQ

Do I need headphones for 2hives?

Only if a session uses stereo tones. Guided voice sessions work on speakers. 2hives is free to use.

What do studies say about binaural beats?

Studies disagree and ask different questions. 2hives does not claim tones do anything beyond sounding the way they sound.

Is there anything to watch with binaural tones?

Binaural tones are a kind of audio, so keep the volume moderate. People with epilepsy, seizures or hearing conditions should check with a doctor first.

Can I use earbuds?

Yes, if both ears are in and the volume is comfortable. Over-ear headphones suit some people better.

What if I do not like the tones?

Choose a session without them. Plain guided voice works well.
