Sony's latest WH-1000XM4 wireless active noise cancelling headphones will launch in India on September 18. The new headphones come with the same dual microphones and QN1 noise-cancelling chipset as the previous generation, but have a new SoC that samples music and ambient noise 700 times per second. Along with wear detection, there's Adaptive Sound Control that can learn and apply a custom sound mode for different locations and a new Speak-to-Chat feature that automatically pauses the music when the user starts speaking or when they takes the headphones off. The headphones also support gesture controls, Google's Fast Pair feature and can be paired with two devices simultaneously. The WH-1000XM4 headphones get a claimed battery life of over 30 hours with active noise cancellation on, and cost $350 in the US. While there's no official word on Indian pricing, reports indicate it could be below the ₹30,000 mark.
