The WF-1000XM4 looks to have a much better fit in ear than its predecessor.
IPX4 rating as well as LDAC, wireless charging and improved ANC with new V1 chip.
8 Hours battery with ANC on (12 Hours with ANC off) and a further two charges in the case.
Improved call quality with new tech.
279.99 euros. Releasing soon (hoping for June)
Love it when a company listens to customer feedback and gives us those improvements. They have literally addressed every flaw with the previous version.
For me, at least on paper, this is the one TWS that will tick all the boxes especially since I love the sound of the XM3.
