#214 DUNU DK4001: $899.00 HiFiGo eBay

Pros: Its hybrid design pairs a 13mm dynamic driver with four balanced armatures, and at 112 dB sensitivity and 32 ohms it plays loud from a phone. HypetheSonics’ measurement shows its best match is a warm, bass leaning taste, and its rating equals the Audio-Technica ATH-CK2000Ti. A preference score of 60 leaves plenty of room for listeners willing to apply EQ.

Cons: Presence is about 8.1 dB under target and air about 7.7 dB under, with a 12 dB hole near 11.9 kHz, so vocals sound distant and cymbals lose shimmer. A 6.1 dB peak near 7.7 kHz on top of that uneven treble, 3.52 dB of deviation overall, adds edginess to sibilants. Sub-bass sits about 5.2 dB low, and it rates below the Fatfreq Reference Pro SE and InEar StageDiver SD5.
