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.
This test report belongs to a different type: Cx (NC, 9 h, Wireless)
Very good83/100
- Good sound
- Extensive setting options
- Bluetooth with aptX
- Favourable price

For under 100 euros, you get above-average headphones with the Sennheiser CX True Wireless.

The podium is completed by the Sennheiser CX True Wireless. Only 0.4 points separate second and third place. At 129 euros, the cheapest in-ear headphones in the top three impress with a solid performance in the sound area, don't make any downward mistakes in workmanship and wearing comfort and even win the looks category...
