Koss sues Apple over wireless headphone patents, wants royalties

Koss, the American company that essentially launched stereo headphones in 1958 with its invention of the Stereophone, is suing Apple over its sales of wireless stereo headphones.

According to Koss’ claim, discovered by Patently Apple, Apple allegedly violated five of Koss’ patents, all of which relate to the use of wireless technology to create wireless stereo headphones:

  • 10,206,025 – System with wireless earphones
  • 10,298,451 – Configuring wireless devices for a wireless infrastructure network
  • 10,469,934 – System with wireless earphones
  • 10,491,982 -System with wireless earphones
  • 10,506,325 – System with wireless earphones

Koss is asking the courts to award damages based on Apple’s alleged liability to Koss in “an amount that compensates it for such infringement, which by law cannot be less than a reasonable royalty, together with interest and costs.”

If the lawsuit is successful, it could award Koss damages well into the millions of dollars.

Digital Trends did not immediately get a response from Apple or Koss when we contacted them about this lawsuit. We will update this story when we hear back.

Given that Apple owns Beats, one of the most popular brands of wireless headphones, as well as being the maker of AirPods and AirPods Pro, two of the most popular models of true wireless earbuds, the claimed royalties that Koss is seeking would be substantial.

But if Apple has indeed violated Koss’ patents as the company alleges, then surely it isn’t the only company to do so. Koss says as much in the text of its claim: “Apple and others are reaping enormous benefits due to John C. Koss’ vision, and Koss Corporation’s commitment to that vision for more than six decades.”

It’s not clear why Koss hasn’t named these “others” in its suit. For its part, Koss claims that it had several meetings with Apple to discuss the patents in question, but Apple allegedly denied any infringing activity.

Despite its reputation as one of the earliest innovators, and its broad product line of headphone models, including some that are wireless, Koss has failed to capture much of the current conversation around personal audio.

It lacks the slick marketing muscle of brands like Beats, Skullcandy, and Apple, and has had a hard time keeping up with innovations like active noise cancellation (ANC), which companies like Sony have used to set new standards within the headphone market.

Perhaps most critically when comparing Koss to Apple, Koss has yet to sell a model of true wireless earbuds, the newest and hottest segment of the personal audio space.

Apple AirPods Max 2: what we know, what we want, and how much it will cost
Apple AirPods Max with USB-C in Orange.

Apple's first set of wireless headphones -- the AirPods Max -- launched to great fanfare in 2020. At $549, the aluminum-clad cans raised eyebrows due to their price and design. But despite their cost and some odd design decisions (like the lack of an off switch), reviewers were nearly unanimous with their praise, especially for the Max's standout features: active noise cancellation (ANC) and transparency mode. Is there room for improvement? Absolutely.

Originally, we had hoped to see the AirPods Max 2 debut in the fall of 2023. When that didn't happen, we shifted our focus to Apple's iPhone 16 launch on September 9, 2024. That event brought big updates for the AirPods range: new AirPods 4 and AirPods 4 with ANC, and plans to give the AirPods Pro 2 new hearing health and hearing aid capabilities. However, the AirPods Max portion of the announcement proved to be a disappointment: Other than a new USB-C charging port and some new colors, Apple's flagship headphones remain unchanged. Call them AirPods Max 1.5, if you must.

Beyerdynamic launches new flagship wireless earbuds and headphones
Beyerdynamic AMIRON 300 and AVENTHO 300.

Beyerdynamic has revamped its top-of-the line wireless earbuds and wireless headphones with two new models, the Amiron 300 ($280) and Aventho 300 ($400). They'll be available in black or white color options when they go on sale in October.

The naming convention of the new models may confuse some long-time Beyerdynamic fans. Historically, the company has used the Amiron name to refer to its wired and wireless over-ear headphones, like the open-back Amiron Home and the wireless Amiron Wireless. However, the new Amiron 300 are the company's flagship wireless earbuds (the company's first wireless earbuds are the Free Byrd.)

1More says its $90 SonoFlow Pro HQ51 headphones are better than Bose and Sony
1More SonoFlow Pro HQ51.

1More has released two new upgraded products in its wireless headphones and open-ear earbuds lineup with the SonoFlow Pro HQ51 ($90) and Open Ear S70 ($120). Both will be available mid-to-late August, with $20 discounts for those who order during the promotional launch window.

The SonoFlow Pro HQ51 picks up where the original SonoFlow leaves off -- the two models have a nearly identical shape and design. Comfort may be slightly enhanced -- the new cans now use leather ear cushions. 1More has given battery life (which was already outstanding at 50 hours with ANC) a bump to 65 hours, a number that jumps to 100 when you turn ANC off.
