• Ease across your whole range

    The back pressure does part of the work your throat was doing. The same note, less effort.

  • A warm-up you can do anywhere

    Humming through the Zangger VoicePipe is far quieter than singing scales — backstage, in the car, in a hotel room at midnight.

  • A voice that comes back faster

    Used as a cool-down after a gig, a long teaching day, or a day of talking — not just before one.

  • Less strain when you go high

    Not a bigger range. An easier one.

  • The same resistance every session

    So when something feels different, you know it was you — not the tool.

  • Published research behind it

    Developed by Dr. Daniel Zangger Borch, whose 2008 doctoral thesis on the singing voice was supervised by Johan Sundberg. The mechanism is peer-reviewed, and we are specific about what we claim and what we don't.

Ten minutes a day

Quiet enough to use anywhere

Humming through a semi-occluded tube is far quieter than singing scales, so a warm-up stops being something that needs a room of its own. Before a rehearsal, in the kitchen, in the car on the way to a gig.

Ten minutes is enough. That is the whole point of a tool you will actually pick up.

The science

What the Zangger VoicePipe actually does to your voice

Singing or humming into a semi-occluded tube raises the air pressure just above the vocal folds. That back pressure lets the folds vibrate with less collision force, which is why an SOVT warm-up feels easier on the voice than the same exercise sung into open air.

The VoicePipe is dimensioned for that effect. It is not a drinking straw with a new label. It is used daily in teaching at Voice Centre Stockholm.

But can't I just use a straw?

Questions people ask before buying

Can't I just use a drinking straw?

You can, and it will do something. A straw is narrow, so it gives a lot of resistance at a very small opening — which makes it hard to keep the airflow steady across a range, and easy to push. The VoicePipe's bore and length were chosen to give useful back pressure while still letting you phonate comfortably from low to high. The video above shows the difference.

What about bubbling into a glass of water?

Water adds a fluctuating resistance on top of the tube: the bubbles make the pressure rise and fall many times a second. Some people like that massaging feel. But it makes the load inconsistent, it needs a glass of water within reach, and it cannot be done quietly backstage or in a car. The VoicePipe gives you a steady, repeatable resistance and nothing to spill.

Why is it so expensive?

Because you are not buying a tube, you are buying the dimensions — the bore and length that produce useful back pressure across a singing range — set by someone who has measured them, plus a method to use it with. It is made in small volumes from PA 2200 rather than moulded by the million, and it comes with a lifetime guarantee against breakage in normal use. A straw is cheaper. It was not designed for your voice.

How do I use it?

Ten minutes a day is enough. Hum gently through the Zangger VoicePipe at a comfortable pitch, then move through simple glides up and down your range. You should feel the vibration in your lips and face, not effort in your throat.

What is it made of, and how do I clean it?

The Zangger VoicePipe is made of PA 2200, a polyamide used for durable, skin-safe parts. Rinse it with warm water and a mild washing-up liquid, then let it air-dry. Do not put it in the dishwasher and do not boil it — high heat can deform the tube.

When will it ship, and what does it cost?

Your order is dispatched from Sweden within 3 business days. Shipping is free within the EU and Sweden. Other destinations, including the UK, Norway and Switzerland, are calculated at checkout. Delivery time after dispatch is up to the postal service and varies by country.

Can I return it?

Yes, if the seal is unbroken. You have 14 days from the day your parcel arrives to change your mind, and you pay the return shipping.

It goes in your mouth, so it ships sealed for hygiene. Once the seal is broken we cannot take it back — that is the standard hygiene exception to the EU right of withdrawal, and it is why the seal is there. You can look at the sealed pack all you like; opening it is the point of no return.

If it arrives damaged or faulty, that is our cost and not yours, and you keep the three-year right to claim defects under Swedish consumer law.

Do I need anything else to make it work?

No — the Zangger VoicePipe works on its own. But a tool only helps if you pick it up daily, which is what Vocal Workout of the Day is for: a new voice workout every day, built on the same research. The first 21 days are free and no card is needed.
