With every new generation of the 1000XM series true wireless ANC earbuds, Sony is inching towards creating a perfect earbuds for music lovers and noise haters to enjoy. When the first WF-1000X was announced in 2017, it was the most underwhelming model of the 1000X series (headphones, neckband). Then came WF-1000XM3 in 2019 (they skipped M2 to align the number with the headphone series), delivering competitive noise cancelling but the earbud design is arguably a turn-off. Fortunately, when WF-1000XM4 launched in 2021, the design went through a transformation to look more compact and conventional, in line with the competitors. This made the M4 the most desirable and easily the best true-wireless noise-killer earbuds that kills competition. Hats off to Sony who took over the ANC crown from long-time incumbent Bose in a short span of 5 years. It certainly helps when the previous models maintain price points below S$380.
