During lockdown I sometimes need to work in the same room my husband is in and often have to listen to seminars so it is perfect not to disturb my husband and have protection from EMFs at the same time. I always check SYB products which are 5G tested and recommend!

After a week of research on EMF radiation I was sold on this product. I still wanted to use headphones at my workstation so this was absolutely perfect. For the audiophiles out there, it definitely doesn’t mess with sound quality - if anything it improved my otherwise slightly noisy headphones. Amazing product!

I don't have any way of measuring its EMR-blocking effects in action (at least, not yet, so I need to get on that!), but I have been reading up a bit on dielectric gel to learn more about its unique properties. I figured it honestly couldn't hurt. Earbuds are the only thing I use when talking on the phone, especially when I'm talking for literal hours upon hours with my best good friend, as well as when in the gym working out for several hours on end. And I've heard for a while that they're a safer option than keeping your phone right next to your head all the time. But until recently, I'd never even considered the fact that they still do transmit cellphone radiation through the ear canal directly into the brain. If I'd hardly ever use my phone like my parents, I probably wouldn't care too much, but being in my mid-20s, it's sort of a different story. I did not like the idea of having to buy yet another headset, only with air tubes, just to be able to avoid extra radiation while not knowing how well they'd even work. And I was dismayed to learn that the air tubes seemed to be the only feasible option when I first started researching this issue. So I'm glad I found this headset add-on, & that it's actually a thing, because it's way more convenient, & I love the idea that I can use it with virtually any earbuds I want. It's always attached to my headset now, & I've already used it several times. Sound quality is just as good as before; it's lightweight, portable & doesn't create a hassle when in use. It's there & you don't even know it. So yeah, all in all, I'd say it's a good purchase. I'd still like to test it out in the future to get some tangible measurements, but as I said, it really can't hurt.

I used to have emotional symptoms and since I started watching my exposure, they’ve decreased dramatically. I wear headphones A LOT so I feel more comfortable having this.

Taking away all the electricity in my ear-phones as far as I can fell, and that was a lot. It also doesn’t have any chemical smell at all. Also very light.
