Bose accuses Beats of using patented noise-cancelling tech

Bose Corp. filed a lawsuit on Friday that accuses popular headphone maker Beats Electronics of infringing upon several of its patents.

The suit claims that Bose lost sales because Beats—which Apple announced it would acquire for $3 billion in May—used patented noise-cancelling technology in its Studio and Studio Wireless headphone lines.

Beats’ products that allegedly use the technology “can also be used for noise cancellation when no music is played, a feature that Beats also advertises,” the suit states. “Thus, Beats specifically encourages users to use the infringing functionality. Beats advertises no method to turn off features that cause end users to directly infringe.”

Bose is probably taking advantage of the fact that Beats is now valued at $3 billion. But why didn’t they wait a few months more? Apple doesn’t yet own Beats, and any money that can be obtained in a suit like this would come from Beats, not Apple.

Also, noise-cancelling technology is quite old; I’m surprised that there are patents like this, but these may simply be patents that refine the technology.

I’m reminded of the Grateful Dead’s wall of sound concerts, where sound engineer Bear (Stanley Owsley) discovered that he could cancel out the sound coming from behind the musicians using two microphones. If you watch The Grateful Dead Movie you can see those noise canceling mikes: the singers sing into the top one, and the lower one picks up the sound from behind them to cancel it out. Alas, the technology was in early stages then, and the sound of the vocals from that period isn’t great.

Why Would Apple Buy Beats?

Rumors have circulated for the past few days that Apple is in discussions to buy Beats, the headphone and streaming audio company, for $3.2 billion. Assuming this turns out to be true, and not a hoax, like the recent story about earbuds with blood pressure sensors, which the gullible tech (and non-tech) press reported gleefully, […]

Use Headphones to Snap Shutter on iOS Camera

An article on TUAW today pointed out something I didn’t know: you can use Apple earbuds to snap the shutter on an iOS device when taking pictures. The article mistakenly says that you must snap the Volume + button; both volume buttons work for me. But what’s interesting is that it’s not just Apple earbuds […]

Thoughts on Apple’s New EarPods

It’s been years since I’ve used Apple’s earbuds with an iPod or iPhone. I’ve long been a fan of good, light headphones, and my go-to cans for when I’m moving around are Sennheiser’s PX 100-II i, a light, foldable headset with an inline mic and iOS device controller. But I got a set of Apple’s […]
