are bone conduction headphones dangerous?

Rather, listeners are at risk of cochlear damage from overuse of any type of earphone. The fact that these earphones use bone-conduction transducers does not inherently make them any safer than any other earphone, as bone-conducted sound is transduced by the cochlea similarly to air-conducted sound.

Generally, this type of hearing loss is conductive and is temporary. However when otitis media occurs over and over again, damage to the eardrum, the bones of the ear, or even the hearing nerve can occur and cause a permanent, sensorineural hearing loss.

While both earbuds and headphones present the risk of high decibel levels and long exposure, earbuds are actually more likely to cause damage. Since earbuds sit right inside your ear and are very close to the ear canal, they naturally increase the volume by around 9 decibels.

The headphones and tubing are all made from synthetic plastic materials, so the headphone is completely inert, and will not affect the MRI scan in any way. The Scan Sound headphones can all be used safely inside of the Magnetic Resonance Imaging scanners and are considered to be MRI safe.

With bone conduction headphones, you don't put anything inside or over your ear. ... Perhaps most importantly for runners, bone conduction headphones don't impede your hearing when you're listening to music. Because your ears are still open, you can hear traffic and other environmental sounds that are critical to safety.

No...it is NOT safe to wear headphones or earbuds while riding a bicycle or when driving a motor vehicle. As far as the law is concerned, according to AAA, it is against New York law to wear more than one earphone that is attached to an audio device while driving. So, that rules out headphones completely.

They emit as many as 14,000 short bursts of intense microwave radiation a day, disrupting cellular electrochemistry and causing health symptoms from migraine to tinnitus, insomnia, dizziness, anxiety, chest pain, palpitations and memory loss. Now a growing number of 'electro-sensitives' have had enough!

Headphones that go over your ears can also damage your hearing if you use them too long or play music too loudly. They're just not as much of a risk as earbuds are: Having the source of the sound in your ear canal can increase a sound's volume by 6 to 9 decibels — enough to cause some serious problems.

But it is highly likely that the other music you are listening to is interfering with the frequency response process and therefore the entrainment is neutralized. I would personally stick to just listening to binaural beats in headphones with no other music playing, and minimal external distractions.

During the past decade, the damaging effects of excessive noise pollution from portable stereo earphones have gained attention. If you can hear the sound being delivered into a person's ear via headphones or earphones, it indicates the sound is too loud and over an extended period can lead to permanent hearing loss.

— are so loud (140 or more decibels), ANY brief exposure to them at close range can cause permanent damage and hearing loss. Sounds at 100 decibels (such as loud music through stereo headphones) will take a while longer (1-2 hours of exposure) to cause permanent damage to hair cells in the cochlea.

So What's the Bottom Line? Noise cancelling headphones themselves don't pose any risk for your health. Noise cancellation technology in the headphones works well without any adverse consequences. They don't emit any radiation whatsoever, so you shouldn't worry about these headphones causing issues to your health.

Moreover, the risk of hearing damage from headphones is higher than with loudspeakers, even at comparable volumes, due to the close coupling of the transducers to the ears. In loudspeaker reproduction, sounds must travel several feet before reaching the listener's ears.

The reply from Bose was: "I would avoid getting the electronics wet. The good news is that you can get a QuietComfort® 35 headphones ear cushion kit. ... "Generally, we don't recommend that the QC35 headphones be used during exercising, mainly because sweat can prematurely break down the headband and cushion material.

Safety. Occupational exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body, and it has been calculated that exposures above 180 dB may lead to death.

Nonetheless, you should replace the wire (if possible) or replace the headphones, if they are hard-wired. Bare wires, regardless of voltage, can spark. ... While the voltage from the headphones is not particularly hazardous, a fire caused by them could result in grievous bodily injury or death.
