Review: Excellent sound quality (when buds and/or ear hooks are fitted properly)! - 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.
Review: Most uncomfortable headphones - The sound is fine. It's comparable to my regular headphones (I was using iPhone headphones that come with my phone). I'm mostly using these for conference calls, so don't need great quality. What I found were 2 issues. 1) The earbuds keep falling out of my ears. The tube doesn't move as fluidly as a wire and it's heavy with the metal piece it connects to, so if you move, the ear buds kept popping out of my ears. I've tried the other earbud accessories w/ the hooks, but those weren't hooking into the rook of my ear well, so I would jam the ear bud and hook as hard as I could into my ear to stay put, which was very uncomfortable. I tried the plastic hooks, but those loosely clip to the ear buds and loosely sit on my ear, and awkward to put on. They're also uncomfortable on the ear, unless you're used to that. 2) I wear hoodies a lot, and the metal joint connected to the end of the tube plus the volume control kept rubbing against the zipper of my hoodie, and I could hear all of that noise. I used the included clip to restrict the tubes from touching the zipper, but that was a delicate balance between the of wire available before the volume control and my head movement. The clip prevented the metal from rubbing on the zipper, but doesn't prevent the ear buds from falling out bc now you're limited to your movement and the tubes flare out like a stethoscope. Overall, it's more grief to use these headphones. These are my first pair of airtubes, so I'm not used to them, so as my first experience with them, they're frustrating to use. It's a bummer bc the sound is good.

### ⭐⭐⭐⭐⭐ Work excellent for phone calls, good audio quality
*by E***. on February 15, 2020*

My main concern was that the inline mic wouldn't work well or wouldn't sound good because I use these for all my cell phone use. They work wonderfully. I use them all day for business calls and they actually seem to pick up less vehicle noise than the my iphone's built in mic. No distortion, no muffled quality. Also the earbud's sound quality really is fantastic. I have been using panasonic headphones for years and haven't really wanted to go back since these. Also, the build quality seems great. They really do seem worth the money. The cord seems a bit thin, but I have been using them all day for weeks while I am working with the cord getting yanked and pinched in my pocket and I have seen no damage yet and the tips that go in your ear are very heavy duty. These are well made. Also, please recognize that the comments about the magnets in the earbuds are for the old version. These are the new ones that don't have that feature.
