Short answer: the DUNU DK4001, though neither ranks well in its class. It ranks #1019 of 1291 in-ear headphones by sound quality, rated 2.9/5, at $899; the Ultimate Ears UE7 ranks #1086, rated 2.6/5, and costs $999, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
The case for the DUNU DK4001: 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. The tradeoff: 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.
What the Ultimate Ears UE7 does well: Its tonal tilt of -0.21 sits close to the target, so the overall balance is neither dark nor bright. Watch for: A Harman score of 56 places it in the lower part of the in-ear rankings.
Buy the DUNU DK4001. It is rated higher for sound quality than the Ultimate Ears UE7 and costs less, which makes it the one to get unless you need something the other one does better.
