Short answer: a tie on sound quality. Both are rated 3.9/5 (#486 and #541 of 1291 in-ear headphones) at nearly the same price ($100 vs $99), so choose on features and fit.
The case for the Audio-Technica ATH-CKR7TW: Crinacle’s measurement gives it a solid Harman preference score of 73 with a 2.18 dB spread. The tradeoff: Its 2.18 dB spread is less even than the best measured sets.
Why pick the qdc SUPERIOR: A broadly balanced tuning with a preference score of 72 against the Harman target. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Audio-Technica ATH-CKR7TW or the qdc SUPERIOR on features: they are rated the same for sound quality at close to the same price.
