How to Spot Fake Bone Conduction Headphones Before You Buy
Published 2026-10-11 · Updated 2026-10-11
The short answer
Play audio at a low volume, then plug both ear canals with your fingers. If the sound gets louder or stays the same, it is real bone conduction, because the vibration travels through the skull. If it drops to almost nothing, the sound was coming through the canal and the product is air conduction sold as bone conduction.
Some headphones sold as bone conduction are air-conduction designs in a different housing. The two look similar in a listing photo. One test separates them in about ten seconds, and a few specification details confirm the result.
What does "fake bone conduction" actually mean?
It means a product marketed as bone conduction that is really air conduction. The housing may sit near the cheekbone, the listing may use the words, and the price may look plausible, but inside there is a small speaker aiming sound at the ear canal instead of a transducer vibrating through the skull. This is not always deliberate deception. Air conduction is a legitimate design with real advantages: it is lighter and often clearer in the mid-range. The problem is the label. A buyer who wants the behavior of bone conduction, meaning the lower leakage, the cheekbone vibration and the way it keeps working with the canal plugged, is buying a different set of properties than the one on the box. Knowing which design you actually have changes how you use it, what to expect from bass, and whether earplugs will help or hurt.
What is the ten-second test?
Play audio at a low volume, then plug both ear canals with your fingers. That single step tells you which technology is in the frame.
Real bone conduction: the sound gets louder, or stays roughly the same. The vibration is travelling through the skull, so blocking the canal does not block the audio.
Air conduction sold as bone conduction: the sound drops to almost nothing. You have just plugged the path the driver was using.
Do the test at low volume so the result is about the pathway, not the level. If the sound is unchanged or louder with your fingers in, the frame is vibrating through bone. If it collapses, the sound was coming through the canal and the label is wrong. This test needs nothing but your hands, and it works on any pair you already own or can try before buying.
What should you feel, and where should the sound sit?
Bone conduction produces a distinct vibration against the cheekbone, and at higher volumes that vibration can feel lightly ticklish. The contact point matters: the transducer should press on the bone in front of the ear, not float in the air beside it. Air conduction feels different. The drivers sit just outside the canal and fire inward, so you hear the sound arriving at the ear and feel little or nothing on the bone. That difference is a second confirmation after the finger test. If the frame only feels like a small speaker resting near your ear, treat it as air conduction no matter what the listing says. If you feel a steady tickle in the cheekbone that tracks the music, you are holding the real thing. Feel and pathway should agree, and when they disagree, the finger test wins.
What should the specification line say?
A genuine bone-conduction product describes a transducer, not a speaker aimed at the ear. The KORAVIS M2, for example, lists a 15.5 mm vibration driver rated 15.50 mW into 8 ohms. The wording is the tell. Look for terms such as vibration driver or transducer, and look for the contact point on the cheekbone in the product photos. A listing that only says "open-ear speakers," "stereo drivers" or "surround sound," and shows nothing resting on bone, is describing air conduction, whatever the headline claims. Specifications are harder to fake than adjectives, because a number has to describe something real. Read the driver description, the contact point and the included accessories together. If the accessories include earplugs, that is a strong hint the product expects to work with the canal blocked, which only bone conduction can do.
Does a low price mean it is fake?
No. Price is a weak signal on its own, and it can point the wrong way. A low-cost frame can still be genuine bone conduction, and an expensive one can still be air conduction with a premium label. The KORAVIS M2 is bone conduction and listed at $15.18, with the list price shown as $17.98, well below what many buyers assume bone conduction costs. So the useful question is not how much it costs but which technology it is. Judge the mechanism first, using the finger test and the specification line, and let price come second. Treating a low price as proof of fakery will make you skip honest products. Treating a high price as proof of authenticity will make you overpay for a label. Neither shortcut survives a single careful test.
How do you check a listing before it arrives?
Work through the evidence in order of how hard it is to fake. Product photos come first: can you see a transducer resting on the cheekbone, or only small speakers near the ear? Specifications come next: is there a vibration driver described, or only generic speaker language? Accessories come third: are earplugs included, which implies the sound survives a blocked canal? Then read the conduction label on the model. KORAVIS states the technology plainly, marking the M2 and M3 as bone conduction and the Q1 as air conduction, rather than blurring the two. If a listing is vague about which one it is, that vagueness is itself information. When the frame arrives, run the ten-second test to confirm. The table below shows how the two KORAVIS designs differ.
| Model | Conduction | Water rating | Playtime | Bluetooth | Listed price |
|---|---|---|---|---|---|
| KORAVIS M2 | Bone | IPX6 | Up to 12H | 5.4 | $15.18 |
| KORAVIS M3 | Bone | IPX5 | Up to 12H | 5.4 | $15.98 |
| KORAVIS Q1 | Air | IPX5 | Up to 8H | 5.3 | $9.98 |
Both designs are honest products. The point of the test is to know which one you have before you rely on it.
FAQ
How can I tell if headphones are really bone conduction?
Play audio at a low volume and plug both ear canals with your fingers. Real bone conduction gets louder or stays the same; air conduction sold as bone conduction drops to almost nothing.
What does fake bone conduction mean?
A product marketed as bone conduction that is really air conduction, using a small speaker aimed at the ear canal instead of a transducer that vibrates through the skull.
Do cheap bone conduction headphones exist?
Yes. Price is not the signal. The KORAVIS M2 is genuine bone conduction and listed at $15.18, with a list price of $17.98, so a low price alone does not mean the technology is fake.
What should a bone conduction spec line say?
It should describe a vibration driver or transducer rather than a speaker aimed at the ear. The KORAVIS M2 lists a 15.5 mm vibration driver rated 15.50 mW into 8 ohms.
Why do some models include earplugs?
Earplugs let a bone-conduction headphone keep working in noisy places, because the vibration still travels through the skull while the plugs cut background noise. On an air-conduction model, plugging the canal would cut off the sound.
