In-ear headphones with hybrid drivers for superior sound standards

4.5 / 5

The most affordable in-ear monitor to date from 64 Audio goes its own way with its hybrid partly open design. The sound tuning is in line with the ideals of the American manufacturer but aims less at audiophile neutrality and analysis, and more at listening pleasure. But don't worry: these are still headphones that deliver plenty of detail and monitor quality. You can expect the highest level of sound enjoyment in the price range above one thousand euros.

Ultrasone Signature Natural

Wired, closed over-ear headphones to meet high demands

4.1 / 5

Ultrasone's Signature Natural are coherent-sounding and pleasingly airy closed headphones that are aimed first and foremost at musicians and producers with high demands for quality. They are a robust and precise tool that aims to provide honest sound reproduction as the basis for sound evaluation. Their closed construction makes it possible to work in noisy environments and to use the headphones as a monitor in the recording room. In terms of fit, however, the Signature Natural is not necessarily "everyone's darling".
