Sony is acquiring Audeze, a U.S.-based maker of audiophile-grade wiredheadphones, IEM-style (in-ear monitor) earbuds, andgaming headsets. But in a weird twist, it’s not Sony’s electronics division that is doing the deal. Instead, it’s Sony Interactive Entertainment (SIE) — the division that oversees the company’s gaming portfolio including thePlayStation 5console. The terms and cost of the acquisition haven’t been released.

“Audeze is a premier brand for headphones, and this acquisition highlights Sony Interactive’s focus on innovation and providing the best audio experience to PlayStation players,” said Hideaki Nishino, Senior Vice President, Platform Experience at Sony Interactive Entertainment in a press release. “We’re excited to bring Audeze’s expertise into the PlayStation ecosystem, building on the great strides we’ve made with PlayStation 5’s Tempest 3D AudioTech and the Pulse 3D wireless headset.”

When Sony revealed that its newPulse Explore wireless earbudsfor PlayStation 5 use planar magnetic drivers, I was surprised. Planar is a fairly exotic audio tech that has historically been limited to wired earbuds that cancost as much as $1,000. It seemed like an even stranger move given that, to my knowledge, Sony Electronics hasn’t created any personal audio products that use planar drivers. The Audeze acquisition explains it —Audezeis known for its use ofplanar driversand holds several patents relating to the technology.

The press release discusses this aspect specifically:

These headphones use Audeze’s patented technologies and unique planar magnetic drivers to deliver an outstanding sound experience for consumers as well as recording professionals, including sound engineers at many game development studios.

Still, despite Audeze’s clear lead in planar and its presence within thegaming community, it’s weird to see Sony’s gaming division acquire an audio company that makes very similar products to SIE’s sister division, Sony Electronics.

SIE says that once the acquisition has been completed, Audeze will continue to operate independently and develop multi-platform products, while benefiting from being a part of the PlayStation ecosystem.

The open question then becomes: To what extent will Audeze’s technology filter over to Sony’s electronics division? Will we see a future version of the company’s flagshipwireless earbuds— theWF-1000XM5— that use planar drivers? We’ll just have to wait and see.
