SP21 AIRCALL : Air Tube Anti-Radiation Headsets

TRIPLE TECHNOLOGY PNEUMATIC EARPHONES FOR CELLULAR AREA OF APPLICATION

• Protection against electromagnetic radiation in direct contact with the inside of the ear

• Eliminates the EMF emitted by the electric currents supplying standard earphones.

• Prevents the electromagnetic propagation effect of cellular phones through the electric cables of standard earphones

PROPERTIES

Acoustic chambers brain’s remoteness

Miniature speakers of "standard" headsets made of permanent magnets generate a magnetic induction (and therefore an E.M field) very next to the brain. With  SP21 AIRCALL, the ear-tips  placed in the ear canal do not  contain any magnetic elements or likely to generate EMFs. The transducers

 are located at a significant distance from the brain, in two small chambers or sound cavities:

this distance corresponds exactly to the W.H.O (world health organization) recommendations, confirming that the remoteness of EMF is the most effective way to reduce the effects.

Wireless transmission by  hollow tube

The sound is then generated  by the transducers vibrating the air in the hollow tube

Cable shielding

Since the jack plug, all the wiring is covered with an insulating shield made of a weaving of pure copper wire, preventing the external dissipation of EMF along the wired part. All these properties justified the decision of the Chinese Army to equip their air pilots with this patented technology.

Safety distance from the brain with  SP21 AIRCALL

The SP21 AIRCALL allows to keep away from the brain any electric or electromagnetic field  (from wiring and headphones components ) with a cable length of 1.26 meter, remoteness explaining the reduction of exposure by more than 99%. SP21 AIRCALL earphones are equipped with a patented system of  acoustic chambers (sound cavity) for each ear: the sound is reproduced by amplification in the acoustic chamber and then transmitted by an air tube to the ear.

INSTRUCTIONS FOR USE

SP21 AIRCALL is to be used like all headphones: a jack allows the standard connection for all mobile phones, a small attachment clip (provided)

keeps the earphones at the right height, and the ergonomic shape of the ear-tips guarantee a good fit of the headphones, whether driving, on the train, or while jogging.

The kit comes with a pair of spare membranes: if you need other membranes, ask your local distributor.

NOTE: SP21 AIRCALL prevents the propagation of EMF along the standard headphones’ wirings.. However, it does not prevent the effects

related to EMF emitted by the phone itself on the rest of the body: a complete and responsible equipment is proposed in the form of a pack:

it associates the MP24 EASYCALL (pastille to stick on the telephones ) and the AIRCALL pneumatic earphones: this is the DP21 AIRCALL pack. If you purchase already SP21 AIRCALL, for a total protection, we recommend you buy also MP24 EASYCALL and stick it to your smartphone.

ADVICE TO USERS FOR THE GUARANTEE:

1. Avoid letting the headset plug into the laptop’s audio jack when stored in a bag. This tends to create excessive mechanical pulls on the wires of the earphone jack and thus leads to a breakage of the wires prematurely, which will not be covered by the warranty.

2. Do not wrap the wire around the notebook for the same reasons.

3. Pacemaker and defibrillator users warning: By applying the optimum precautionary principle, and due to the presence of a permanent magnet in the transducers, the product is contraindicated with pacemakers users as similarly to any standard headphones.

WARNING! As a matter of hygiene, our “money back” guarantee cannot be applied to this product. No exchange will be accepted on open / used material. Thank you for your understanding
