Sony MDR-EX15LP vs Panasonic RP-HJE120

Last updated: October 11, 2026

Short answer: the Sony MDR-EX15LP. It ranks #351 of 450 in-ear headphones by sound quality, rated 3.5/5, at $11.99; the Panasonic RP-HJE120 ranks #445, rated 1.3/5, at $10.99. Close enough in price that the sound-quality gap is the deciding factor.

Sony MDR-EX15LP vs Panasonic RP-HJE120

The Sony MDR-EX15LP is the better-sounding choice. In oratory1990’s measurement it earns a preference score of 68, a strong result for such an inexpensive in-ear, with the midrange from 1 to 10 kHz within half a decibel of the Harman target. Watch for: A 7.2 dB dip near 11.9 kHz and air about 3 dB below target take some sparkle off cymbals.

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. The tradeoff: 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 Sony MDR-EX15LP. It is rated higher for sound quality, and saving $1 with the Panasonic RP-HJE120 does not make up for the sound-quality gap.

Pros: In oratory1990’s measurement it earns a preference score of 68, a strong result for such an inexpensive in-ear, with the midrange from 1 to 10 kHz within half a decibel of the Harman target. Bass runs about 4.7 dB above target, giving pop and hip hop a full, punchy low end. At 16 ohms, 100 dB/mW and 3 g per earbud it is light and easy to drive from a phone, and it rates above the KZ ATE and the HIFIMAN RE400.

Cons: A 7.2 dB dip near 11.9 kHz and air about 3 dB below target take some sparkle off cymbals. The TRN MT1 and the TANGZU Wan’er S.G both rate higher at a similar low price.

Panasonic RP-HJE120 ranking card

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.
