KZ EDX Pro vs Panasonic RP-HJE120

Short answer: the KZ EDX Pro, though neither ranks well in its class. It ranks #61 of 68 in-ear headphones by sound quality, rated 2.7/5, at $17.99. The Panasonic RP-HJE120 ranks #68, rated 1.3/5, at $10.99, $7 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 68 in-ear headphones, and the Truthear Gate, ranked #5 at $21.99, is a better place to start if sound quality matters.

The KZ EDX Pro is the better-sounding pick. 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.

Why pick the Panasonic RP-HJE120: It is a very cheap wired earphone with a 9 mm dynamic driver, 16 ohm impedance and 95 dB/mW sensitivity, so it plays loud from any phone or laptop. Watch for: That bass boost spills into the low mids, which are 4.8 dB over target, so vocals and instruments sound thick and muddy.

Buy the KZ EDX Pro. It is rated higher for sound quality, and the $7 you would save on the Panasonic RP-HJE120 does not close the gap.

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.

Panasonic RP-HJE120: $10.99 Amazon eBay

Pros: It is a very cheap wired earphone with a 9 mm dynamic driver, 16 ohm impedance and 95 dB/mW sensitivity, so it plays loud from any phone or laptop. Bass is lifted about 8 dB over target in oratory1990’s measurement and sub-bass is up 2.3 dB, which suits listeners who simply want a big, thumpy low end.

Cons: That bass boost spills into the low mids, which are 4.8 dB over target, so vocals and instruments sound thick and muddy. Treble is rolled off by about 2.2 dB and air by 4.3 dB, with an 8.7 dB dip near 11.9 kHz, so cymbals lack sparkle. The preference score of 40 is the lowest among its rivals, and each of those rivals has a higher rating, including the TRN MT1 at a similar cost.
