DUNU x KOTO ITO VS ddHiFi Memory E13p

Z-Reviews original ranking

DUNU x KOTO ITO is a $199.99 hybrid IEM built with Japanese reviewer Kaji Kaji (“Koto”). It uses a 2DD+2BA array (10 mm bio-diaphragm DD + 8 mm LCP DD, plus two treble BAs), comes with DUNU’s Q-Lock quick-swap plugs, and lists 105 dB sensitivity at 37 Ω with shells at ~6.5 g each.

Tonally, ITO aims for a U-shaped, bass-tilted balance: sub/mid-bass punch is elevated, mids sit slightly back but avoid haze, and treble is smooth with workable extension rather than bite. Early community impressions frame it as energetic and a touch V-leaning versus DUNU’s more neutral sets, which tracks with the collab’s “full-bodied” intent.

Technicalities are competent for the class: dynamics and imaging keep up with busy mixes, while soundstage and microdetail are closer to average among sub-$200 hybrids; driveability is friendly given 105 dB/37 Ω. As a package—tuning, accessories, and fit—it offers good value for listeners wanting engaging bass without sharp treble, though those chasing expansive stage or strict neutrality may prefer other options.

ddHiFi Memory E13P combines a semi-in-ear “hybrid” fit (side-firing tube + tips) with a single 13 mm planar driver and a fixed USB-C DAC/amp using the Cirrus Logic CS43198, targeting phone-first listening without extra dongles. ddHiFi cites a MOONDROP-developed planar unit and decoding support up to 32-bit/384 kHz plus native DSD256, with an MSRP of $169.99.

Tonally, performance lines up as neutral-U: a modest sub-bass lift for punch, clear (slightly recessed) mids, and a forward but controlled treble that keeps cymbals crisp without obvious glare; detail retrieval and imaging are competitive for the price, while stage width is decent if not panoramic. Multiple third-party impressions echo this balance, noting solid bass texture, clean separation, and lively top-end energy suited to pop/rock.

Trade-offs are clear: the fixed USB-C cable/DAC limits source and connector flexibility (no cable rolling), and the semi-in-ear geometry offers only moderate isolation; on the flip side, claimed low THD (<0.05%) and high efficiency make it easy to drive cleanly from a phone. As a travel-friendly planar under $200, E13P prioritizes convenience and competent technicals over ultimate stage size or tunability, yielding strong value if you want plug-and-play clarity with mild bass/treble lift.
