These are by far my favorite headphones. I have purchased many types of headphones. At first, looking for comfort. I do not like buds that’s are required to sit in the opening of my ear. In the past I have tried smaller buds because my ears would get sore. I’ve even tried different materials because they made my ears itchy. I work using my hands so I prefer wireless headsets and needed headphones that remain charged throughout my shift. Plus, price always matters, as I strive to shop on a budget.SO THESE ARE A WIN FOR ME!!! They are comfortable, light weight and sit on the ear rather than in the ear. I sometimes forget they are on my head. They don’t slide off and are a pretty sturdy, yet flexible set of earphones. The volume and sound quality are great and they are almost unrecognizable when worn (for those who care for looks. Fully charged, the battery gets me through an entire 8 hour shift. To top it off, THESE HEADPHONES WERE WORTH THE PRICE AND I RECEIVED THEM QUICKLY!!I run on a regular basis and wanted to be able to hear my surroundings while having music playing. This does just that and has served me well thus far. I've had it for a couple weeks now and still haven't needed to charge it (I run about 4 times a week for ~40 minutes). The only downside is you can't expect to hear much if anything if you're in a crowded space (like a gym) or by a busy street. The sound isn't pristine but personally that's not important to me; what's more important is hearing what's around me with some background music. It's also very comfortable! I often forget that I have it on and I don't have to hassle with it during my workouts. I haven't tried it out in water (I honestly don't have the need to currently) and there seems to be no issues when I run during the rain. Overall, I highly recommend.As a retired Truck Driver and Retired Army, I do not like it when it is totally quiet; I can not sleep. I am too used to at least engine or generator noise. So when it is dead quiet, I can not sleep.Enter why I ordered your Bone Conduction Headphones. I use them every night; I either play music or have an audiobook playing to cancel the absence of noise.I wear them at night when I sleep, the charge lasts the entire night, and it is comfortable to wear. I also love that it is open ear because it allows me to have the noise I need to get to sleep and doesn't block out noise entirely as the old fashion headphones do. So if the is an emergency, I can still hear if someone is trying to wake me.I say all this so you understand precisely why I love these bone conduction headphoneWe were looking for a way to listen to music while bike riding and still be able to hear cars approaching. These headphones are comfortable and work pretty well once you figure out the best way to wear them. I have a smaller sized head (wear child-sized bike helmet) so these are pretty large for me. I find that putting the back under my ponytail at the back of my neck positions the 'sound conductors' properly and I can hear the music really well.These are not 'fine' sound quality, but very good for their purpose. They pair easily to I phones by bluetooth.You can wear them with sunglasses and a bike helmet and they do not interfere with either.One improvement would be - add an LED that shows when the charge is nearing depletion. They just say "low battery" and shut off without warning.We both have them and are pleased with them.This new Mionbel even better than my first bone headphones, because of the upgrades on the side power on and off and underneath volume up and down so nice and easy to use. If you ride ebike or run this is so nice to hear music or pod cast and still hear all around you. The comfort is great also. Nice to not worry about them falling off while ridding. I strongly recommend getting bone way better than the put in your ear bluetooth.It's as u would k8nda expect and outer ear experience not as loud as inner ear--ear buds and the like but I wear them to work in an environment of 'NO HEADPHONES' This is a great work around cuz its mainly to hear and I can still hear my surroundings.wish it was more accommodating with dreads ? but I stillwear them fine.(EAR PLUGS DO MAKE A DIFFERENCE BUT THEN....doesn't that kinda defeat the purpose of these outer ear "bone conductors" to hear ur surroundings ??) they are good nonetheless 4out of 5 seems reasonableSince these do not go inside the ear this is great. They do rub the top of my right ear and I have to have them real low for others not to hear what is playing on them. The battery charge seems ok and sound is not bad. These would be better suited for outside than inside. I do not wear the ear plugs because these were supposed to replace the in ear pair I already owned and kinda defeats that purpose.As others have mentioned, these are oddly large and stick out about an inch from the back of my head. Would not recommend for use while running/playing sports. However, the sound quality is good, the battery has lasted for 10+ hours at a time, and they're quite comfortable to wear at work or around the house.
