In recent years, “bone conduction” has become one of the most widely used phrases in audio marketing. You’ll see countless pairs of glasses claiming to offer open-ear sound through bone conduction, yet in many cases the technology being used isn’t bone conduction at all. Instead, it’s often a tiny air speaker disguised within the frame, an approach that looks similar but works very differently. In this article, we’ll explain how to recognise genuine bone conduction, how to spot imitation designs, and why the distinction matters for comfort, safety, and tinnitus relief.
Understanding what true bone conduction means.
True bone conduction doesn’t use air movement or a traditional speaker cone. Instead, it transmits vibration through the bones of your skull, usually the temporal bone near the ear or the cheekbone just in front of it. These vibrations reach the inner ear directly, bypassing the eardrum altogether. The result is a subtle, natural form of hearing that allows your ears to remain completely open. When a product relies on air to carry sound waves, or you can clearly hear the audio projecting through the air, it isn’t genuine bone conduction. Even if it sits near your ear, it is simply an air-conduction speaker in a different shape.
Spotting where the sound really comes from.
A reliable way to tell the difference is to examine the point where the sound originates. Genuine bone conduction devices have flat pads or transducers that rest directly against the bone, usually on the cheekbone or behind the ear on the mastoid area. The pads should sit flush with your skin, not hover near or inside the ear canal. When you block your ears and the sound stays consistent, that is a clear sign that vibration, not air, is carrying the audio. If covering your ears makes the sound almost vanish, then it is an air-conduction speaker, not bone conduction.

What real bone conduction feels and sounds like.
Genuine bone conduction has a distinct feel. You will notice a slight vibration on your skin when the volume is moderate or high, and the sound profile tends to be lighter and more focused than standard headphones. Low frequencies are naturally reduced because vibration through bone carries mid and high tones more efficiently than bass-heavy sound. This does not mean the quality is poor; it simply means the experience is different. You are not listening through your ears, you are listening through your body. If you ever test a pair of glasses that sound as rich as in-ear headphones and you cannot feel any vibration, it is almost certainly not true bone conduction.
Common imitation designs and how they work.
Many low-cost glasses that advertise bone conduction simply use small directional speakers hidden within the arms of the frame. These speakers send air-based sound toward your ear canal. The result can seem convincing at first, especially indoors where reflections help reinforce the sound, but step outside and you will notice a drop in clarity and consistency. The audio leaks to people nearby, and the sound quality depends heavily on how close the speaker is to your ear. Because no vibration is being transmitted through bone, this design is really just open-air playback disguised as innovation.
Some models go halfway, using a mild vibration motor combined with air speakers. These are often called “hybrid” or “vibration-assisted” designs, but the effect is cosmetic rather than functional. They might buzz against the skin yet still send most sound through air, not bone. These hybrids often cost less than £25 and can be found on marketplaces under unrecognised brand names or without detailed specifications. True bone conduction requires more advanced components and fine-tuned placement, which is why reliable products tend to come from established manufacturers that invest in acoustic design.
A simple test you can do at home.
The easiest way to check whether a pair of glasses uses real bone conduction is the “blocked-ear” test. Play music through the device, then plug your ears completely with your fingers or earplugs. If you can still hear the sound clearly and feel a light vibration on your cheekbone or temple, you are hearing genuine bone conduction.
If the sound drops significantly when your ears are covered, it is an air speaker. You can also try turning your head slightly; authentic bone conduction should sound steady because the vibration is travelling through bone, not through air between the device and your ear.

Why this distinction matters.
For people exploring tinnitus relief, hearing comfort, or open-ear listening, the difference between real and fake bone conduction is not just technical; it is experiential. True bone conduction provides a gentle, private soundscape that helps the brain relax, reduce contrast, and stay connected to external sounds. Air speakers, on the other hand, can isolate you from your surroundings while leaking sound into the environment. This affects comfort and focus, and it also touches privacy and safety, especially in outdoor or professional settings.
How Sonovo ensures genuine bone conduction performance.
Sonovo Unison uses dedicated bone conduction transducers designed to deliver stable, low-pressure vibration through the cheekbones. Each pair is tuned for clarity, balance, and consistent comfort, ensuring that what you hear is true vibration-based sound, not disguised air conduction. The open-ear design keeps your environment audible, which suits people who live with tinnitus and anyone who prefers a safer, more natural listening experience. You can learn more in The Science Behind Sonovo Unison™ or explore our range of Tinnitus Relief Devices.

Choosing with confidence.
When comparing bone conduction glasses, look beyond the marketing language. Focus on how the product behaves when your ears are blocked, how consistent the sound feels when you move, and whether the company explains how vibration is generated and transmitted. True bone conduction is quieter, steadier, and feels like sound that belongs to you rather than sound floating in the air. If you take a moment to test it properly, you will notice the difference immediately, and that awareness helps you choose technology that genuinely supports your comfort and wellbeing.
