DefenderShield Air Tube Stereo Earbuds USB-C - Universal Acoustic Wired Headphones with Mic & Volume Control

Excellent sound quality (i was quite surprised!). Granted, the sound delivery is not super high-fidelity, and unless you are accustomed to in-studio type headphones or ear buds, these perform very well. With that in mind, you absolutely must spend the time to achieve a proper fitment (or as other's have noted, they will fall out of your ears). The in-line controls are intuitive and easy to use, just be careful to not pull from your ear when adjusting them (if not using your device controls for functions). These are not anything like the conventional and EMF dangerous Apple or standard ear buds! Note to the lazy or convenience oriented users.... spend the time and follow the instructions included, or your experience will be less than favorable. Regarding physical activity usage (as opposed to static activity, such as reading or working at your desk), again, I highly recommend initial proper fitment (and they will stay inserted!), or wear something else without EMF protection, and potentially damage your brain. Edit 12/13/2025: Noticed other reviewers having issues wearing these while sleeping... what? You should never be listening to headsets while sleeping in bed (particularly with the typical wireless, or wired styles)! And wearing with a hoodie, of course there will be ergonomic complications rubbing the blue tubes, etc.) so it's not recommended to wear hoodies while using these.

Why make a case where you need to coil the tubes? They are pretty much molded in a coil and when you put them on the tube maintain their shape and you can imagine how they dangle around your head. Why not make a staring and slim case to keep the tube straight? Maybe you have good scientists but bad engineers. Sound quality is noticeably worse than Apple Air Pods.

After just 4 months of using it one pair stopped working no sound!!! So disappointing!! quality is very bad!!

Absolute garbage and the 30 day return policy is just short enough for a busy person NOT to have time. DO NOT BUY!!! Horrible sound quality and constant echo. I have to be on the phone most of the day for work and these are unusable. Every time I take a call with them on people complain about their own voice echoing back at them and my voice doing the same. I paid extra for these because they are supposed to be the safest. Now I here these are a very highly returned item on Amazon. Of course the ad only show 5 star reviews which is ridiculous. Please see in this item description that amazon now has a warning that the item is highly returned.

These air tube earbuds work great. The sound quality is excellent and I’ve had no problems. Most of all, they give me peace of mind knowing that I am cutting down on EMFs.
