Below are excerpts from the review:
“The ddHiFi Memory Pd4.4 delivers a tuning approach that is rarer and more deliberate than its price tier would typically produce: a neutral-warm planar signature that places vocal intimacy and midrange honesty at the center of the presentation rather than chasing the Harman-curve bass and treble emphasis that most budget planar IEMs use to create immediate impact. The 13mm MOONDROP-developed driver’s low distortion, the palladium-plated copper housing’s passive isolation advantage over the AL4.4 variant, the KIWIEARS KIWIFLEX eartip set, and the overall material quality position the Pd4.4 convincingly at its price point in terms of what it puts in the box and how it sounds.”
