Do Bone Conduction Headphones Leak Sound?

Bone Conduction Headphones are a truly unique piece of tech. They are completely different from any other earbuds on the market. But do bone conduction headphones leak sound?

All headphones can leak sound if they are used on maximum volume. Some amount of sound leakage is normal and acceptable. Bone conduction headphones don’t leak significantly more sound than other types of headphones. Bone Conduction Headphones do leak more sound than in-ear headphones on average.

Read on to learn why there’s sound leakage from bone conduction and all forms of headphones. We will also share a few handy tips that will help you reduce sound leakage.

According to, all headphones leak some sound; bone conduction headphones also leak sound because the sound escapes from the sides of the transducers. The headphones have drivers that vibrate to create sound. The vibrations are strong enough to make small gaps between the headphones and your skin.

If your bone-conducting headphones have vents, there’ll be even more leakage. The problem is further amplified when you listen to loud music because the drivers create even stronger vibrations. That’s the reason why bone-conducting headphones leak more sound than in-ear style earbuds. 

Some In-ears headphones or earbuds use silicon or foam tips to create a strong seal. On the other hand, bone conduction headphones don’t have any way to create a seal. They sit directly against your skin, and they even move a bit if they’re not tight enough. Combine this with loud metal blasting against your temple, and it becomes a recipe for sound leakage.

But How Bad is The Sound Bleed on Bone Conduction Headphones?

But How Bad is The Sound Bleed on Bone Conduction Headphones?

It’s very similar to other types of headphones, which is not so bad. Most people around you won’t hear your music unless you have them at extremely high volume, so you’re safe to listen to classical rock if you like.

When was the last time you heard someone’s earbuds on the street? There’s already so much traffic and other noise that you can hardly hear anything. So, your music session stays private. If you want to be extra safe, lower the music a bit.

The only time someone may hear sound from your bone conduction headphones is in very quiet places. People sitting extremely close to you can also hear some music. Remember this when sitting next to strangers on an airplane, bus, or train.

How to Reduce Bone Conducting Headphone Sound Leakage

You don’t have to stop using bone-conducting headphones because of sound leakage. After all, they are the safest regarding awareness, most convenient, useful, and comfortable way to listen to music outdoors.

Also, as we often discuss in our articles on headphones, Bone Conduction Headphones are one type of headphones we use depending on our circumstances and what we are doing.

While you can’t completely stop sound leakage, there are a few ways to reduce it.

Lower the Volume

The louder the volume on your headphones, the more sound leaks because of the stronger driver vibrations. To counteract that, you may want to lower the volume a bit. But remember that you can hear your headphones much louder than people around you.

So, you don’t have to make them completely silent. It’s enough to lower the volume to 60-70%.

Of course, you may not want to listen to loud music in the first place. Constant loud music causes hearing loss because it damages your cochlea. Bone conduction headphones are not any safer in this regard.

Use Better Bone Conduction Headphones

Have you ever noticed that bad earbuds are always obnoxiously loud to bypassers? Bone conduction headphones aren’t any different. A cheap pair will always have more leakage, while bad earphones often let you crank up the volume way louder than what’s considered safe.

Let’s look at AfterShokz as an example. They are one of the pioneers of bone-conducting headphones, so they had plenty of time to hone their craft. Their latest earphones come with LeakSlayer technology. In a nutshell, the headphones cancel out their sound from the outside.

It’s the same principle that noise-canceling headphones use. A separate driver plays the opposite soundwave to the main driver, which causes the sound to cancel out.

Get Better Fitting Bone Conducting Headphones

Earbuds need to fit perfectly into your ear to reduce sound leakage, which is why they give you a few different size silicon tips. You also want your bone-conducting earphones to fit snug against your skull. If it’s too loose, they’ll slide around, which can significantly increase sound leakage.

But you can’t just fit a new pair of ear tips to them. Most people won’t have trouble with the standard size. However, if your head is too small, the earphones will slide around too much. They might even slip off.

AfterShokz explains in their video how to tell what size fits you:

How Do Bone Conduction Headphones Work?

Bone conduction headphones work by transmitting the sound through your bones instead of air. The sound travels directly to your cochlea instead of the eardrum picking up vibrations.

It’s a true marvel of engineering. But where did the sound engineers get the idea for bone conduction headphones?

Well, you actually use bone conduction every single day. When you speak, your voice transmits sound waves to your ear through the skull. That’s why we cringe when we hear our voices in recordings. 

We usually listen to ourselves through our bones. Bone-conducting headphones use our bones for the same purpose. The sound travels from the temple to the cochlea, which is located in the inner ear.

Are Bone Conduction Headphones Worth It?
