Work well if you use them correctly.
So I was a little conflicted based on the reviews but ended up ordering these and they work really well for my use case! There's a few caveats though I think trip a lot of people up judging based on the other reviews. First, these require a certain amount of output power from whatever they are connected to in order to work and they are not amplified internally (not getting into technical details here just at a high level). Some devices I have can drive them adequately including my cellphone but others can't including an old MP3 player I happened to try. On the devices that do work I find I have to turn the volume up higher than usual to get clear audio. Second, you need to place them in a certain location on the side of your head to really get the full effect. If they are slightly off they will work but the sound will be very muffled or low volume. If they are way off they don't work at all for me. Luckily the headband places them in about the perfect place on my head but sometimes when I wear a hat over them I need to move them around a bit to get them to sit correctly. Third, even when they work perfectly they are not going to sound great. The point of these is that they are wired, so you're not dependent on bluetooth working correctly in your environment, and they don't need their own power, so you don't have to charge them. If these are not things you want they you'd likely be much better off with a pair of bluetooth bone conduction headphones. Personally these work really well for my use case and I'm going to buy another pair to keep as a spare in case the first ever breaks. I never use the microphone on them so I can't comment on how well that works.

Does not sound good at all. Bluetooth headsets are way better
I have recently started using bone conduction technology, and overall I am pleased with the technology. Yes, the sound quality is not as good as a set of regular headphones or headsets, but for the most part it's passable; I can hear podcasts, I can hear calls, I can hear music, I can hear video game sound. These however, are horrible. Yes, you can hear podcasts, you can hear calls, you can hear music, and you can hear video game sound, but the quality of the sound is unacceptable to me. I absolutely do not recommend these unless you really really need wired bone conduction headphones, since they are the only ones that are available (at the time of this writing).

extremely quiet but works with my computer
My old over-ear headphones completely cover my ears, hurt after several hours and get ear wax build up (after days of passing the time recovering from corrective surgery). I needed open ear to let my ears breath. Bone conduction sounds perfect (unintentional pun). And, these were the least expensive of the very limited (corded, bone conduction 3.5mm headphone/earphone) choices. But, they are not supposed to work with computers, because of the microphone? I do not need the microphone.. I hoped and waited for them to arrive. Plugged them in.. no sound. Wait a minute! Turn the volume ALL THE WAY UP! Ah, conversational volume. LOL Good enough? Maybe.. For the price? Got to love it! Remember, the round part goes on your cheek bones directly in front of your ears, not on your ears. They do squeeze a little but that is necessary, to push against the bone for bone conduction. And, they are simple (durability and inexpensive.)

Compact and Comfortable !!
They work great and don't affect my hearing .

Junk
As other reviewers said, they are very low volume. If you use them in a quiet place with foam earplugs in, with an amplifier, you’ll be able to hear. Even so, the sound quality will be poor. I have other bone conduction headphones which I’m very happy with. I wanted a wired set and this was the most popular, but they are cheap junk. I would have been willing to pay 5X more for something that actually works, but no such option exists. These are trash.

Good, but quiet
Overall, these are pretty decent headphones. I'm using them with a small pocket radio and foam ear plugs. I need to wear hearing protection at work and these work quite nicely when I'm wearing my PPE; they actually sound better with ear plugs in than without. As other people have pointed out, they are fairly quiet and don't have the best sound quality, but they're also passively driven (non-amplified) and relatively inexpensive. The build quality is pretty good too, I don't feel like they're going to break if I sneeze too hard like many other products I've encountered. Edit: about a month later the wires have started to fail at the 3.5 jack. Dunno if it's poorly made or if I'm just that hard on em.

play around with the settings
I don't know if this useful for anyone else, but using this with LG G8X phone. There are two default sound apps on the phone that help with the sound volume and quality. DTS:X 3D Surround set to Wide for music and Front for listening to podcasts. Hi-Fi Quad Dac Equalizer set to Treble Booster and Digital Filter set to Short has the best sound quality for listening to music or podcasts equally. I have the volume at 60 to 75/100 and everything comes out clearly.

So quiet
Bought 2 of these for watching TV through my Roku remote. 1st pair isn't to bad but quiet. 2nd pair is so quiet with volume completely cranked I can barely hear. And strap isn't at all adjustable.

Se escucha super bajito
Haber, para usar en un trabajo que tienes que llevar tapones puestos si te funcionarán.. pero sin tapones, no valen pa' na...los quería para ensayar con la claqueta y escuchar la banda a la vez pero se escucha muy muy bajo, no los recomiendo más qué para el caso dicho al principio, no son tan baratos y dan muy muy poco sonido y la diadema para un concierto es incómoda y no casa bien... tiré el dinero.

Non sono realmente a conduzione ossea
Non sono realmente cuffie a conduzione ossea, hanno dei driver come quelli delle cuffie normali, ma incapsulati. Si sente anche senza avere le cuffie appoggiate alla pelle. E, anche appoggiando le cuffie, il volume è bassissimo e la qualità audio è pessima (anche rispetto ad altre cuffie a conduzione ossea che ho provato).

funcionan bien
funcionan bien, solamente en lugares con ruido no es suficiente el volumen
