Same summary

The Sennheiser CX 80U, USB-C headphones are primarily suitable for users looking for the simplicity of a wired connection and a discreet, lightweight in-ear design. Due to the USB-C connector, they are particularly adapted to modern phones, tablets and computers without a classic headphone output. It is worth noting that the wired connection provides minimal latency, which is useful for video calls and watching content, but the headphones are less intended for users who expect advanced noise cancellation or wireless freedom of movement. The compromise compared to larger over-ear models is mainly in sound isolation and comfort during very long use.
