Spiegel TestsTrue-Wireless-HeadsetsReleaseApril 2024

That's how they sound: The CX True Wireless are better suited to the synthesiser sounds of Jean-Michel Jarre than to the guitar rattling of Spoon. They reproduce the synth sound clearly and powerfully, whereas the Spoon song lacks precisely this clarity in the bass range. For my taste, they could be a little louder.
