What is a 30mm driver

Manufacturers often make up for the lack of bass in headphones with balanced armature drivers by adding dynamic drivers into the mix, creating a new type of driver known as hybrid drivers.

The lack of air movement allows BA drivers to operate without additional air vents, helping them to create better sound isolation. A single BA driver also has a very narrow frequency range, meaning more than one driver is required to make headphones with good sound quality — resulting in higher price tags on the final products.

Planar magnetic drivers are also known as isodynamic, magneplanar, or orthodynamic drivers. Headphones with planar magnetic drivers often have a signature appearance with rectangular openings on their ear cups instead of circular ones. Similar to dynamic drivers, planar magnetic drivers produce sound using magnetic fields. The key differentiator is how the magnets move the diaphragm and the shape of the diaphragm itself. Instead, they use a flat electrical conductor in between two equally flat magnets.

The conductor will be electromagnetic and move back and forth towards the permanent magnets, resulting in the diaphragm vibration. The larger magnets inside the drivers mean that the headphones are heavier, bulkier, and more expensive than those with dynamic or balanced armature drivers.

However, the stationary magnets and flat diaphragms make the sound created by planar magnetic drivers more well-controlled and less prone to distortion at higher volumes. Planar magnetic drivers also have a more accurate sound reproduction compared to others. But most headphones that use planar magnetic drivers often require an amp to achieve their best sound quality. The electrostatic driver is the most expensive driver type among all others on this list.

Electret drivers have a permanent charge on the film, eliminating the need for specialized amplification. When an electrical current is applied to the perforated plates, the film will vibrate due to the magnetic attraction and repulsion. The vibration will move the air and create sound waves. However, headphones with this driver are generally the most expensive of the bunch.

They also have incredibly high impedance, which means they require a specialized amp to boost the audio signal and turn down the electric current to a safe level.

Piezoelectric drivers work by applying a voltage to piezoelectric material such as crystal or ceramics to move the diaphragm. Due to the atomic-level workings of piezoelectric materials, this driver is incredibly sensitive to changes in sound frequency and volume. In other words, they can convert even the weakest audio signal into sound. This limitation results in piezoelectric drivers having overall low-quality sound while requiring a high power to work.

While bone conduction headphones are fairly new to the scene, they are gaining popularity among enthusiasts and regular consumers alike. There are now dozens of bone conduction headphones like the famous AfterShokz Aeropex. However, many people have debated the safety of bone conduction headphones , there have been cases where prolonged use of bone conduction causes discomfort, skin irritation, and headache.

These drivers vibrate the temporal bones and jawbones to transfer the sound directly into the inner ear. As the name implies, headphones with hybrid drivers combine two or more different drivers to produce the best sound quality.

Not all drivers are equal — some can handle a certain frequency range better than others. By combining more than one driver type in a pair of headphones, the frequency range of said headphones will be much wider, therefore improving their overall sound quality.

Thread starter Modulus Start date Jun 5, Tags sennheiser-ie tdk-ie Modulus Head-Fier. Joined Feb 4, Posts 69 Likes Hi all. I was wondering what technical differences one could expect between 8mm and 10mm drivers in IEMs.

Is one of these consistently 'better'? My intuition tells me that 10mm should deliver better bass performance and a more impactful sound. Could anyone shed some light on this matter? Doing so delegates certain range of frequencies to each armature—bass notes will usually be handled by an individual driver, and the rest will be handled by one to three others, allowing drivers tailored to each frequency band to be used.

As with all things, you have to make a cost-benefit analysis. Whether you want something cheap and functional or luxurious and analytical , dynamic drivers have you covered. Most consumers will be perfectly happy with the dynamic driver type of headphones. Of course, if audio is your passion and you have the means to pursue that passion, planar magnetic, electrostatic, and balanced armature-driven headphones are worthy upgrades.

Although these driver types require a bit more shopping around, there are plenty of options out there. And as demonstrated by the Monoprice Monolith , not all planar magnetic headphones have to set you back thousands of dollars. Next up: How to read charts. Check Price. Name: Subject: Message:.
