Headphone driver types: Which one's just right?

www.soundguys.com

While there’s plenty of reading on those questions, we’re here to give you a quick and easy breakdown of the different headphone driver types: dynamic, planar magnetic, electrostatic, balanced armature, and MEMS. ... This article was updated on January 6, 2026, to correct minor inconsistencies. This article was updated on November 4, 2024, to update the information about MEMS speakers. Balanced armature drivers (“BA”s) are much smaller than the other driver types, and their main application is in-ear monitors (IEMs) and hearing aids. These incorporate a magnetic armature that rests on a pivot and rotates between two magnets. Doing so delegates a specific range of frequencies to each armature— an individual driver will usually handle bass notes, and the rest will be handled by one to three others, allowing drivers tailored to each frequency band to be used. Of course, if audio is your passion and you can pursue that passion, planar magnetic, electrostatic, and balanced armature-driven headphones or earbuds are worthy of potential upgrades. Although these driver types require a bit more shopping around, plenty of options exist.

Headphones and earbuds set to change dramatically by 2025 - SoundGuys

We’re about to see the end of some of wireless audio’s most significant shortcomings, with improved solutions to how listeners hear and more convenience in battery-reliant products. The fact that this is all happening simultaneously might make heads spin, but it’s worth knowing what’s coming down the pike in 2025 when you make buying decisions in 2024. The performance upgrades are twofold: MEMS speakers can move air very fast, leading to extended high-frequency bandwidth, and the near-zero part variance will make them better equipped to support spatial audio content as the driver performance will be better matched between left and right channels. The extended bandwidth (up to 80kHz) has also been leveraged in a clever spin on this new technology by the company xMEMS in its new Cypress product, demonstrated at CES 2024. Several driver types are available for earbuds and headphones, but none are as exciting as the Microelectromechanical Systems (MEMS) speaker. In a leap of tech as stark as the jump from hard drives to solid-state drives (SSDs), MEMS speakers are entirely different in form from the traditional moving coil or balanced armature driver designs, with an impressive list of claims. While it won’t happen overnight, earbuds moving to full-range MEMS drivers over balanced armature and dynamic drivers will entice manufacturers looking to make the case for their wares in a crowded market.

What is a MEMS speaker? - SoundGuys

Sonion has electrostatic MEMS tweeters (electret) designed for use as tweeters that offer superior performance to traditional balanced armatures in IEMs. It enables electrostatic performance in IEMs without the usual separate power supply for stepping up the voltage and supplying bias to the driver. For over four years, xMEMS labs has been working on an all-silicon solid-state speaker driver with plans to roll out the tech more widely in 2024. MEMS speaker driver technology provides distinct advantages compared to dynamic and balanced armature speakers. Manufacturers like Creative Labs, Noble Audio and Singularity Industries have already incorporated these solid-state drivers into earbud products. They promise excellent sound quality, use fewer materials, and are virtually indestructible while being more cost-effective. More examples will be released in 2024, so expect to hear more about solid-state MEMS-driven earbuds. The acoustic output is up to 40 times louder than xMEMS’ prior-generation speakers that used traditional transduction in the audible frequency band. xMEMS claims that its latest generation prototype, Cypress, shown for the first time at CES 2024, can reach more than 140 dB (SPL) even at 20 Hz, the lowest frequency we can hear.

The best IEMs in 2026 - SoundGuys

www.soundguys.com

IEMs block external sound using passive acoustic isolation and provide clear audio in specific frequency regions, such as the vocal range. They often use balanced armature drivers, smaller and lighter than typical dynamic drivers, and are known for their high-frequency extension. In-ear monitors generally offer better sound quality than typical earbuds, especially in terms of clarity and isolation. The use of balanced armature drivers in many IEMs leads to a more precise and clear sound at high levels. This list was published on October 23 14, 2024, to add the Moondrop Aria 2 to the notable mentions. This article was published on January 18, 2024.

Those seeking a pair of high-quality IEMs should enjoy the Kiwi Ears Septet. These feature seven internal drivers: a single dynamic driver, four balanced armatures, a planar magnetic driver, and a piezoelectric (PZT) driver. The last is uncommon among IEMs and is usually reserved for speakers to cover the high-frequency range. Linsoul KZ ZSN Pro X ($23.99 at Amazon): The KZ ZSN Pro X are an excellent ultra-budget IEM option with a replaceable two-pin cable and hybrid 10mm dynamic and balanced armature drivers. They follow our target curve reasonably closely with only a small 5dB bump at 5kHz. This includes validating over-ear headphones in a 2023 study led by Senselab, an in-ears Harman research pilot study conducted by Dr. Sean Olive in early 2024, and validation alongside the Harman IE 2019 Target specific to the B&K 5128 for use with in-ears in a published AES study on October 8, 2024. Moondrop Aria 2 ($89.99 at Amazon): Finally, the Moondrop Aria 2 offer a premium wired listening experience with a replaceable 2-pin cable, pressure vents, and a 4.4mm balanced connection that’s ideal for Digital Audio Players. Their sound quality tracks our preference curve, with a marginal dip in the mids and a boost in the upper-midrange at 2kHz and 5kHz.

What is the Knowles Curve? - SoundGuys

The Knowles Curve is important since it will likely be the guidepost for how earbuds that use Knowles balanced armature (BA) drivers will sound in the near future. For example, we’ve already started to see products with the latest generation of Knowles hardware and advertise compliance with the target. The company’s balanced armature (BA) drivers show up in many earbuds and in-ear monitors from companies like JLab, Edifier, and Ultimate Ears, as they’ve had good results from having a dynamic driver handle the lows, and BA drivers deliver the high frequencies.
