Air Tube Headphones Headset Air

When we use our cell phones, we’re exposed to high levels of radiofrequency radiation—as you’re no doubt aware. Exposure is particularly high when holding the phone directly to the ear, which is the most common way people use them. In this case, the distance to the brain is very short. Many cell phone manufacturers therefore state that their devices should not be held directly against the ear, but should instead be used at a distance of at least 2 cm from the ear. For reasons of convenience, practically no one follows this advice; most people aren’t even aware of this warning.

Another option is to use a Bluetooth headset, such as Apple AirPods or various other models from Samsung or other manufacturers . Bluetooth headsets are often mistakenly marketed as a “low-radiation way to make phone calls.” This is not the case.

This much is true: If you keep your cell phone farther away from your body (e.g., on the passenger seat in the car), the distance effect means you’re exposed to lower RF radiation than when holding the phone directly to your ear. However, with a Bluetooth headset , you now have a transmitter directly in or on your ear. That’s because the headset doesn’t just receive signals—it also has to transmit your responses back to the cell phone during a call.

In addition, most Bluetooth headsets—which consist of two earbuds—transmit signals from one earbud to the other (i.e., directly through the head) to exchange timing synchronization signals and enable stereo sound. Finally, the cell phone itself now emits more RF radiation, since it transmits not only via the cellular and/or Wi-Fi antenna, but also via the Bluetooth antenna.

Why a conventional headset doesn't solve the problem of electromagnetic pollution:

So far, most people have relied on wired headsets when they want to make phone calls with low radiation exposure. In many cases, however, such a headset can actually significantly increase radiation exposure. Most people who hear this for the first time look completely incredulous and ask, “Why is that?”

The problem stems from high-frequency physics. The metal conductors in the wired headset act as so-called waveguides. They absorb the high-frequency radiation and conduct it directly to the earbud, where it is then emitted directly into the brain at close range (i.e., even closer than when holding a cell phone to your ear).

The British consumer organization Consumers’ Association found in a study [1] that the field strengths inside the ear were up to three times higher when using a wired headset than when not using one. The actual increase in exposure varied and depended heavily on the spatial position of the headset cable. The well-known building biologist Wolfgang Maes reviewed the British study for an article in the magazine “ÖkoTest.”

“We at Baubiologie Maes tested this on behalf of Öko-Test, conducted field strength analyses on 14 cell phones and headsets, and were surprised: All headsets transmit radiation from the phone through the connecting cable to the earbud. Now everything emits radiation—not just the cell phone, but also the plugged-in cable and the small speaker at the end of the cable. This is based on the physical principle of wave propagation.”

The quote is taken from the book *Stress from Electricity and Radiation* by Mr. Maes [2]. This highly recommended book is considered by many—including us—to be the “bible of building biology.” Maes writes in the same book:

"The Federal Office for Radiation Protection is still preaching that a headset would be useful for reducing exposure to electromagnetic fields… Many others are parroting this, preaching the same nonsense."

As a solution to the problem, Maes recommends in his book using an air-tube headset, for example. Many people who previously thought they were on the safe side with a conventional headset will be surprised to learn just how much strain they actually put on it.

The Air Headset – The Ideal Way to Make Calls with Low Radiation

The Air Headset is an air-tube headset that eliminates the very problems that make a conventional headset so bothersome. It blocks sound transmission into the earbud (and thus to the brain) through an ingenious design: The sound is not generated in the speaker inside the earbud, but much earlier in a sound transducer. From there, it is routed through an air tube directly into the earbud and on to the eardrum.

The earbud is therefore now purely a mechanical component; it no longer has any electrically conductive wiring and contains no electrical components—such as a speaker or additional electronics (e.g., noise-canceling)—like those found in the earbud of a conventional headset.

The Air Headset – Key Features at a Glance:

• A stereo air-tube headset is the most practical way to make low-radiation mobile phone calls or listen to audio and watch video streams on your cell phone
• Elimination of the antenna effect and wave guidance through the use of an air tube design.
• No transmission of high-frequency fields to the earbuds and no radiation from them into the brain.
• Significant reduction in magnetic fields by twisting the cables leading to the transducers.
• Excellent voice quality thanks to the sound transducer's high-quality electronics.
• High sound quality ensures smooth playback of audio and video streams.
• High-quality mechanical workmanship ensures great durability in everyday use and a long service life.
• Not bulky: The lightweight and slim design of the earpieces makes the headset very easy to handle.
• Ear tip: The Air headset features a one-size-fits-all ear tip made of hard plastic (no rubber tips). The shape is similar to the ear tips found on Apple AirPods, for example.
• Connection: 3.5mm jack. Important: If your phone doesn't have a headphone jack (especially Apple iPhones and some Android models), you can still use the headset with an adapter, such as a USB-C to 3.5mm adapter.

We've been using the Air headset every day since 2019 for our customer calls.
 The voice quality is excellent, we haven't had any mechanical issues, and we're confident it will continue to serve us well for many years to come.
