After the release of the PM-1, we received feedback from some customers about their desire for increased treble response. Based on this feedback, our acoustic designer has come up with a new ear pad design that has slightly elevated treble response while maintaining excellent bass and midrange performance. The PM-1 will have the original pads installed by default, and the new design will be included as an alternative set for users who want a bit more treble.
Australian owners of the OPPO PM-1 that were originally shipped without the alternative ear pads are eligible to receive a pair free of charge. To request these alternative ear pads, contact your dealer who will arrange the additional ear-pads. These are estimated to be available in late August.
