WE GIVE YOU A FERRITE CORE FOR YOUR HEADSET FROM THE SMARTPHONE. FREE!
Ferrite cores have been used for years on computers and multimedia devices to avoid disruptive interference in the network. These ferrite cores are integrated directly into the electrical cable, HDMI cable, USB cable, etc. as a filter against high-frequency electromagnetic radiation. This EMF radiation is generated by the device during operation and transmits through the cable connection to other connected devices, which may cause malfunction and failure of the connected device.
Even a mobile device such as a smartphone or music player produces such electromagnetic radiation and it is possible that these waves transmitted through the connected headset cable to the head. So why not use the same filter technology for the headset, we thought.
Electromagnetic radiation, which can disrupt sensitive electronics, can also affect our brains!
Those who only walk through the city with their eyes open or who observe people in the bus and train will soon realize that modern people are often on their way in everyday life with their headset or headphones plugged in. It is fortunately reported more and more often about the mobile radio radiation by the smartphone with possible health effects, but is not spoken about the headset as a part of the smartphone set.
Compared to the strong cell phone radiation, the EMF exposure through the headset cable is of course much lower, but this is also included in the electrosmog issue around the mobile phone. And also completely independent of EMF signals through the operation of the smartphone itself or the antenna effect for mobile radio radiation through the metal-containing headset cable.
FERRITE CORE, the simple solution against EMF in the headset cable
This ferrite core is small enough not to disturb the headset cable and the best thing about it – one is FREE and while supplies last. What remains at cost is only the postage of €2.50. A ferrite core makes a significant difference. For optimal protection, however, 3 ferrite cores are required, each one connected to the left and right earphones. We ship 3 ferrite cores incl. postage for a total of 5 Euro. And as friends set even cheaper again. This action “FERRITCORE FOR HEADSET” is limited to Austria and Germany due to the postage costs.
From the crux with the strong magnetic field from the headphones!
Using a ferrite core is a great idea, an improvement and definitely worth a try. However, what remains is just the resulting magnetic field in the headphones themselves ie. two times per headset while listening to music. We were surprised when we were able to directly measure the load of 250 nT directly on the headphone with the simple fast measurement without a large experimental setup – range up to 2 cm. Considering that in ear headphones plug directly into the ear, such magnetic field strengths are definitely an issue.
So if you generally get earache while wearing headphones and especially in the variants that are worn in the ear, this may well be in addition to the electromagnetic field on the magnetic field of the headphones themselves. In order to shield this, special headphones with mu-metal must be used which cause a massive reduction in the magnetic field.
Through the use of mu-metal this reduction of up to 98% can be measured. By all means, values of a few thousand nT can be generated directly on the headphones and, thanks to Mu-Metall, these can be reduced to less than 5 nT. With commercial headphones, such a consideration can not be expected, but in the professional field, however, this change
For example, offers. The manufacturer Ultrasone the model 880 and has thanks Mu-Metall actively addressed this problem. This headphone is designed specifically for those who use their headphones for musical enjoyment for many hours. You will never regret the grip to such a thoughtful headphone.
But back to the favorite application “listening to music” with the smartphone. Are there any solutions that both remove electromagnetic fields and at the same time prevent magnetic fields on the ear? YES, they exist!
AirTube headsets. With the air hose air tube against electrosmog!
Designed for use on smartphones or MP3 players, the Air Tube Headset creates sensational results in terms of electrosmog. Simply put, there is no more electrosmog on the ear.
The functional principle of these AirTube headsets is quite simple. Somewhere in the headset cable, the conversion of the electrical music signal into sound waves takes place. From this point, the sound is passed through an air hose to the ear instead of the usual copper cable. Electromagnetic fields and magnetic fields are therefore sought in vain on the ear.
“And what about the musical quality?”, asks the music enthusiast.
Let’s say so. Anyone who was musically satisfied with a standard stereo heatset will enjoy the Air Tube Headset. However, the AirTubes can not match the audio quality of a modern Apple Airpod headset.
As so often, the ultimate truth is the priority of the topic. AirTube headsets have been developed as Priority 1 to protect against electrosmog on the ear and head. Next comes sound quality, comfort, microphone and compatibility with smartphone control.
However, if the priority is 1 in the music enjoyment and protective measures below either remains an upgrade with ferrite cores or the handle to a headphone with mu metal such as the Ultrasone 880 was designed for electrosmog protected music enjoyment or a mu-metal headset for use with a smartphone.
