Below are excerpts from the review:
“The DDHiFi Memory PD4.4 is not merely a variant of the original Memory—it is a meaningful evolution.
It preserves the speed, resolution, and control that made the original interesting while introducing a more natural tonal balance and a stronger sense of musical engagement.
Combined with exceptional build quality, thoughtful accessories, comfortable ergonomics, and a distinctive semi-open design, the result is one of the more interesting planar magnetic IEMs in its price range.
Listeners seeking maximum analytical precision may still prefer the original Memory. Those looking for a planar IEM that balances technical ability with musical enjoyment will likely find the Memory PD4.4 to be the more satisfying choice.”
