Sony has unveiled the WF-1000XM4 earbuds, the latest model in its 1000X series. The WF-1000XM4 sports an overhauled design, and one that is lighter than the WF-1000XM3 that preceded it. At the heart of the WF-1000XM4 is Sony's new Integrated Processor V1, which the company claims deliver improved noise cancellation. The V1 builds on the QN1e that Sony used in the WF-1000XM3, for reference.
According to Sony, the V1 offers 40% lower noise levels than the QN1e and offers automatic wind detection. Incidentally, Sony claims that the WF-1000XM4's 6 mm drivers have 20% higher magnet volume than the WF-1000XM3's drivers, which aid the former's noise-cancelling capabilities. Touch controls return, as does Amazon Alexa and Google Assistant support. Arguably, one of the more exciting changes is the inclusion of LDAC support, which was missing from the WF-1000XM3. The WF-1000XM4 utilises High-Resolution Audio Wireless as a result, and DSEE Extreme upscaling.
Additionally, Sony claims that the WF-1000XM4 will last up to 8 hours between charges with ANC activated. Its battery life estimate increases to 12 hours with ANC off, but the charging case should give the earbuds another three complete recharges. The bundled charging case supports the Qi wireless charging standard, too.
The Sony WF-1000XM4 is available to pre-order now for £249 in the UK, €279 in the Eurozone and US$279.99 in the US. The earbuds are available in black or silver. Both models come with polyurethane foam tips in three sizes and a USB Type-C charging cable.
