FiiO JT7 vs Sony MDR-7506

Short answer: the FiiO JT7. It ranks #32 of 216 over-ear headphones by sound quality, rated 4.2/5, at $119.99; the Sony MDR-7506 ranks #56, rated 4.1/5, and costs $129.99, so there is not much of a tradeoff to weigh.

What the FiiO JT7 does well: The median of five hobbyist measurements on squig.link gives the JT7 a preference score of 87 with a nearly flat tilt, so it sounds balanced rather than warm or bright. The catch: Sensitivity of 92 dB/mW is low, so a phone or laptop jack may run out of volume and a small headphone amp is a sensible addition.

Why pick the Sony MDR-7506: A preference score of 83 with a deviation of only 1.7 dB from the Harman target in oratory1990’s measurement is excellent for a closed studio headphone. The tradeoff: Presence and treble run about 3.5 dB hot, with a peak of 6 dB near 4.5 kHz, which makes vocals forward and cymbals or sibilance sharp at higher volumes.

Buy the FiiO JT7. It is rated higher for sound quality than the Sony MDR-7506 and costs less, which makes it the one to get unless you need something the other one does better.

FiiO JT7: $119.99 Amazon eBay

Pros: The median of five hobbyist measurements on squig.link gives the JT7 a preference score of 87 with a nearly flat tilt, so it sounds balanced rather than warm or bright. Bass from 60 to 200 Hz sits right on target and the upper mids are level, which keeps voices and instruments natural. It uses a large 95 by 86 mm planar magnetic driver at a moderate 318 grams, and its 18 ohm load is easy for most sources to control.

Cons: Sensitivity of 92 dB/mW is low, so a phone or laptop jack may run out of volume and a small headphone amp is a sensible addition. Those measurements show a 4.9 dB peak near 5.8 kHz that can add edge to vocals, while sub-bass sits about 3.5 dB under target and the open back leaks sound and blocks no outside noise. The HIFIMAN HE400se rates slightly higher and costs less. See headphone amps and DACs with enough power to drive it.

Sony MDR-7506: $129.99 Amazon eBay

Pros: A preference score of 83 with a deviation of only 1.7 dB from the Harman target in oratory1990’s measurement is excellent for a closed studio headphone. Bass and low mids sit within about 1 dB of target, so vocals and instruments sound natural and uncolored. At 260 g with a 106 dB/mW sensitivity, it plays loud straight from a phone or laptop without an amp.

Cons: Presence and treble run about 3.5 dB hot, with a peak of 6 dB near 4.5 kHz, which makes vocals forward and cymbals or sibilance sharp at higher volumes. Air above 10 kHz is about 2.6 dB low, and the wired-only design has no microphone.
