EXCERPT OF RATINGS FROM BUYERS

Great, no cell phone radiation due to the air-conduction technology
I wanted to buy a similar product in stores, the price of about 40 € but then did a little further research.
I found what I am looking for on Amazon: first I bought from the Marketplace dealer maria.pantou: Attention, keep your hands off! I have the customer feedback (are not the reviews !, but only appear when you click on the seller name), unfortunately, read too late. In spite of repeated mail requests on my part, the product never arrived at my place! Then I ordered Hifone from the Markezplace vendor, everything went smoothly there. Technology: The question of whether mobile phone jets are routed directly into the ear via conventional cable earphones and cable headsets be or not, you can save yourself if you play it safe and, for example, also chooses the air-duct technology used here. The sound is passed on electromagnetically as normal as an air chamber and then the pure acoustic sound is led via a plastic hose to the in-ear part. Works perfect and is unbeatable on top of that. My sister has paid for the same product, because it was not available at that time just about Hifone, another provider paid about 25 € and is also fully satisfied.

Super good – good sound quality
I already had an Airtube headset with two earplugs and wanted now to make phone calls with the smartphone even one that is a little smaller, easier to stow and take away, because it is not so easily tangled. Since this headset was a direct hit. The sound quality is very good, it is small and an earplug is absolutely sufficient for telephoning. No more headaches from telephoning thanks to Airtube technology. No hot ears. Wonderful! Highly Recommended.
