- 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.

For that price, I assumed they're b be more durable, but here I am less than a year later and the usb c connector is coming apart. I w wouldn't recommend t these for outside usage Update: I did get replacement quick after submitting for the warranty thing. But the new one didn't last more than probably 2 months. Just mostly sweat alone I guess from the outside work I do messes up the volume control area. And now only the right ear works, same issue as before basically. Sucks I have to use Bluetooth headphones for now

Great concept but they Only lasted 2 months. One of the speakers stopped working completely. While they worked the sound was good. For the price I was hoping to get at least 6-8 months. Unfortunately I will never be buying again.

These are challenging to use. First of all it’s very hard to change the earbud sizes and they constantly fall out of your ears. They constantly shut off when I use them with my iPhone. I have to unplug and re-plug it in multiple times.

I’m really annoyed. I bought the USB C version. The package saids its USB C but the actual headphone inside had a small headphone jack!!! I can’t use it now without a converter!!!!

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!!
