In this week's Episode of Tech n Tonic, we saw the big launch of Sony's next generation Sony Noise Cancelling Headphones, the Sony WH-1000XM4. The new headphones come with the same QN1 noise cancelling processor, but with improved functions. It now has better sound upscaler too, with enhanced personalised noise cancelling and audio processing. This goodness is packaged at MYR 1,599. Is it worth it? We think so, as we discuss.
