9D Breathwork is circular connected breathing done at home, guided by a multi-layered soundtrack through over-ear headphones. There is no facilitator.
We have facilitated over 1,000 sessions and trained in SOMA Breath®, Somatiq, and Rebirthing Breathwork. This is what 9D does well and where it hits its limits.

What Is 9D Audio?
9D audio is the layered headphone soundtrack used in 9D Breathwork. It is a marketing name, not an audio format. No file type or speaker system is called 9D.
It builds on 8D audio, a stereo mixing effect that pans sound from ear to ear so it seems to circle your head. 9D tracks stack more layers on top of that, listed in the next section.
So 9D audio is the soundtrack. 9D Breathwork is the whole practice: that soundtrack plus circular connected breathing, done alone with headphones.
What Plays in 9D Breathwork Headphones
The "9D" stands for nine layers of audio mixed into one track. They usually include binaural beats (two slightly different frequencies that create a third perceived tone), isochronic tones, and solfeggio frequencies, which are often linked to specific energetic states. 8D spatial audio moves sound around you in three-dimensional space.
On top of that sit subliminal affirmations, nature sounds, and a voice coach who gives breathing instructions, guided visualization, and emotional prompts. Music runs through the whole session and sets its emotional arc.
The breathing itself is circular connected breathing. You inhale and exhale continuously, with no pause between breaths. It is the same base technique used in Holotropic Breathwork®, Rebirthing Breathwork, and here at Liquid Breathwork. The audio is what sets 9D apart.
How a 9D Session Works
Before the session
A guide, live or pre-recorded, leads a short intention setting. You can bring a question, an intention, or just openness. Then you lie down, put on over-ear headphones, and cover your eyes with a mask so your attention turns inward.
The build phase
The track opens with music and the guide's voice setting the breathing rhythm. Depending on the track, you breathe through the nose or the mouth and keep the breath connected. Over the first 15 to 20 minutes the music gets more intense and the brainwave entrainment layers start to act on your nervous system.
The peak
Around the midpoint the soundscape hits its loudest, most emotional phase. The voice often encourages you to make sound, move, or let something out. Many people feel tingling in the extremities, waves of emotion, and a warped sense of time. Strong physical sensations come from the shift in blood CO2 that connected breathing creates.
Release and integration
The soundscape softens and the voice guides you to let go. In the final 10 to 15 minutes the music fades and you rest in stillness. Some tracks close with gentle affirmations.
What 9D Breathwork Does Well
- Easy to access. You need headphones, a quiet space, and a device. There is no class, commute, or booking, which matters if you live somewhere remote or have a tight schedule.
- Helps beginners settle. If you are new to Breathwork, the audio gives your mind something to hold while your body does the work. It can quiet the analytical mind faster than silence or simple music.
- Free to start. There is a 7-day free trial, so you can try Breathwork before you commit to a live session.
- The same every time. A pre-recorded session does not change, which helps when you are building a solo home practice.
Where 9D Breathwork Falls Short
We used 9D-style headphone setups in our own group sessions early on, then chose to stop. These are the reasons.
Headphones cannot match the sound of a real room
9D tracks are well made, but headphones only reach your ear canals. A good speaker system in a Breathwork room reaches your whole body. You feel the bass in your chest and the air moving, and even premium over-ear headphones cannot do that. In somatic Breathwork this matters, because the point is to feel the music in your body, which supports nervous system regulation.
When we ran headphone sessions, groups consistently reported a flatter, more muted physical experience than they did after we switched to room speakers, even though the 9D tracks were more complex.
The soundscape pushes outward expression over inward surrender
9D tracks build to a peak where the guide often encourages yelling, screaming, or loud cathartic release. That is not wrong. For some people it is exactly what they need at that point.
In our experience, going deep takes a quieter, more receptive nervous system. Loud expression activates the sympathetic nervous system. It pushes energy out instead of letting the body finish its own cycle of emotional regulation. In a group, one person yelling also pulls everyone else out of their inward focus.
Our deepest sessions have been the quiet ones, with fifteen people moving through deep releases in near silence, held by the group.
Headphones cut you off from the room
When a group breathes together in one room without headphones, their nervous systems start to resonate with each other. You can feel the people breathing around you, and the shared rhythm takes each person further than they would go alone.
Headphones cut that off. Each person sits in their own audio bubble, even next to someone on the same track, and a group session turns into solo sessions side by side.
Pre-recorded audio cannot read the room
A 9D session runs on a fixed timeline. It does not know that three people need two more minutes at the peak, or that the room is lighter today and does not need the usual buildup. It cannot turn the volume down when the room goes still on its own.
A live facilitator can. They adjust pacing and volume, give a cue at the right moment, or say nothing and let the silence hold.
9D Breathwork vs Liquid Breathwork: A Direct Comparison
Both formats have a place. The table shows the trade-offs.
| Factor | 9D Breathwork | Liquid Breathwork |
|---|---|---|
| Format | Pre-recorded audio through headphones, solo at home or in a group | Live facilitated sessions in person (Phoenix, AZ) or online with a live facilitator |
| Sound | Layered binaural and spatial audio, highly produced, delivered to the ears only | Curated music through room speakers, felt in the body as well as the ears, mixed live DJ-style |
| Facilitation | Pre-recorded script. Consistent, but fixed, with no adjustment in the moment | Live facilitator reads the room and adjusts pacing, volume, and cues in real time |
| Group field | Each person in their own audio bubble | Shared sound and energy from breathing together without headphones |
| Release style | Encourages loud, cathartic expression (vocalization, movement, yelling) | Surrender-based, quiet, inward release at the body's own pace |
| Best for | Beginners, remote users, home practice, people who want high sensory stimulation | People who want deep inward surrender, a group to breathe with, and skilled live facilitation; Phoenix, Arizona locals |
| Typical price | No price published on their site. The app is free to download with a 7-day trial; app store listings show subscriptions from $67 a month | Drop-in classes and membership options; see current schedule and pricing |
Who 9D Breathwork Is a Good Fit For
Beyond beginners and people with no facilitator nearby, 9D suits:
- People who specifically want a loud cathartic release. If you need to yell or let out pent-up energy, 9D is built for that.
- People with mobility limitations or health conditions that make in-person sessions difficult.
- People who also go to live sessions. Using 9D tracks as home practice between live sessions is a reasonable approach.
Many of our participants came to us after months or years of 9D and other headphone formats, feeling they had hit a wall with pre-recorded audio. Read verified client experiences from people who moved from home practice to live facilitated work.
A Note for Aspiring Facilitators
If you facilitate and are considering 9D-style headphone sessions, try them in your own groups first. Compare what people report with your non-headphone sessions, and ask whether the cathartic style fits the container you want to hold.
Our guide to becoming a Breathwork facilitator covers training options, facilitation philosophy, and the main decisions in building a practice. If you want training that focuses on facilitation craft over format, see our Liquid Breathwork facilitator training.

What is 9D audio?
9D audio is the layered headphone soundtrack used in 9D Breathwork. It is a marketing name, not an audio format. It builds on 8D audio, which pans sound around your head, and adds binaural beats, isochronic tones, solfeggio frequencies, affirmations, nature sounds and a guiding voice.
What does 9D stand for in 9D Breathwork?
The "9D" refers to nine layers of audio in the soundtrack: binaural brain entrainment, isochronic brainwave tones, solfeggio frequencies, 8D spatial audio, Hemi-Sync style brainwave entrainment, bioacoustic sound effects, subliminal affirmations, nature soundscapes, and music composition. It is a marketing term for the layered sound design, not a clinical or scientific classification.
Does 9D Breathwork actually work?
Many people report emotional release, calm, and altered states of awareness. Circular connected breathing combined with brainwave entrainment can produce real physiological shifts. The tracks also use subliminal suggestion aimed at the subconscious mind, and some listeners report more physical energy, often credited to the 432Hz tuning in the soundscapes. Results vary with audio quality, equipment, and the person.
Is 9D Breathwork safe?
For most healthy adults, it is generally safe. The circular breathing pattern can cause light-headedness, tingling in the extremities, or strong emotional responses. People with cardiovascular conditions, epilepsy, a history of seizures, severe trauma or PTSD, or who are pregnant should consult a doctor before trying any Breathwork modality. Because the audio is pre-recorded, no facilitator is there to monitor you or make adjustments if the experience feels too intense.
How is 9D Breathwork different from Wim Hof or Holotropic Breathwork?
Wim Hof uses rapid breathing rounds paired with cold exposure to create an energizing, activating state. Holotropic Breathwork uses sustained hyperventilation to induce non-ordinary states of consciousness. 9D uses conscious connected breathing (similar in pattern to Holotropic) paired with a highly produced, multi-layered audio environment through headphones.
Can you do 9D Breathwork in person?
Yes. Some facilitators run group sessions where everyone wears headphones in the same room and listens to the same pre-recorded track. Because each person is in their own audio bubble, it works more like individual sessions side by side than a live facilitated group.
