Short answer: the KZ DQ6S, though neither ranks well in its class. It ranks #59 of 68 in-ear headphones by sound quality, rated 2.9/5, at $28.99. The KZ EDX Pro ranks #61, rated 2.7/5, at $17.99, $11 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 68 in-ear headphones, so if sound quality matters, consider the Truthear Gate instead, ranked #5 at $21.99.
Why pick the KZ DQ6S: Very inexpensive, with a 25 ohm impedance and 116 dB sensitivity that make it loud and easy to drive from any phone or laptop. The catch: A preference score of 60 and a 2.83 dB deviation from target show the tonal balance is not accurate, so voices and instruments will not sound natural.
The case for the KZ EDX Pro: Priced among the lowest in the class, which makes it a throwaway-friendly spare pair. The tradeoff: A preference score of 58 and a 2.91 dB deviation from the target indicate an uneven balance that colors vocals and instruments.
Buy the KZ DQ6S. It is rated higher for sound quality, and the $11 you would save on the KZ EDX Pro does not close the gap.

The Two Headphones In Full
KZ DQ6S: $28.99 Amazon eBay
Pros: Very inexpensive, with a 25 ohm impedance and 116 dB sensitivity that make it loud and easy to drive from any phone or laptop. Crinacle measured a mild warm tilt of about 1.1 dB, which gives a smooth, laid-back character suited to bass-leaning tastes. Its rating is higher than the KZ EDX Pro and the Final Audio E3000.
Cons: A preference score of 60 and a 2.83 dB deviation from target show the tonal balance is not accurate, so voices and instruments will not sound natural. There is no built-in microphone, so it cannot be used for calls. The KZ ATE is rated higher at a lower price.

KZ EDX Pro: $17.99 Amazon eBay
Pros: Priced among the lowest in the class, which makes it a throwaway-friendly spare pair. The 10mm dynamic driver, 24 ohm impedance and 112 dB sensitivity are easy for any phone to drive to loud levels. Crinacle measured a warm tilt of about 1.1 dB, a good match for those who prefer a gentle, bass-leaning sound.
Cons: A preference score of 58 and a 2.91 dB deviation from the target indicate an uneven balance that colors vocals and instruments. No microphone is listed, so calls are not an option. The KZ DQ6S, KZ ATE and CCA CSN are all rated higher at a similar cost.
