ConclusionWe honestly expected more from the Sony WF-1000xM4. This pair of in-ears does offer everything the forenzer is looking for in terms of functionality, but it lacks comfort and also a bit of playback quality. The lack of the AptX codec cannot really be explained in our opinion. What a crazy choice Sony made. In short: as far as we are concerned, not a recommendation in this class.
Who are these Sony WF-1000xM4 in-ears for now? We can think of one person: the enthusiast who is on the road a lot and mainly listens to music on their phone. And the person who can appreciate the fit. That’s one point we could not get used to. Too bad… because there is a lot that is good about these luxury in-ears.
