There are many headphone companies around, although when it comes to “luxury” headphones, brands like Bose and Beats probably comes to mind. Both companies, in the audiophile world, are typically viewed as companies who price their headphones for more than they are worth. We guess this is subjective and it really depends on whether you can justify its price, but in the meantime it looks like Bose has hit Beats with a lawsuit. In a recent court filing, Bose alleges that Beats had infringed upon five of its patents, all of which are related to noise-cancelling headphones. The patents in question include Method and apparatus for minimizing latency in digital signal processing systems; Dynamically configurable ANR signal processing topology; Dynamically configurable ANR filter block topology; High frequency compensating topology; and Digital high frequency phase compensation.
