Band: opinion spread · Dot: weighted average
Sources split almost evenly, and the split follows who is listening. Every measurement rig shows the same warm shape — a generous bass shelf, a dip through the upper mids and a soft top octave. Mainstream outlets (What Hi-Fi?, Tom's Guide, TechRadar, PCMag, Trusted Reviews, TechGearLab) and RTINGS hear that as rich, balanced and right out of the box. Measurement-led and enthusiast reviewers (SoundGuys, Chrono, The Absolute Sound, HeadphonesAddict, Soundphile, RecordingNow) and many forum owners hear it as veiled or muddy and reach for the EQ.
Measured
Five rigs agree on the shape. Against the same rig's Sennheiser HD 600 it carries +5 to +7 dB at 100 Hz (oratory1990 GRAS, RTINGS 5128, Super* Review, DHRME, Crinacle GRAS), a dip of roughly 4–8 dB from 1 to 2.5 kHz, presence near level at 4–6 kHz and a top octave 5–10 dB down. Against the Harman target (oratory1990) the bass sits ~5–6 dB high at 100–200 Hz and 1.5–2.5 kHz sits 3–4 dB low; RTINGS labels it 'Warm', bass 'Very Emphasized (6 dB)'. DHRME measures 5–7 dB more sub-bass with ANC switched off.
vs. listeners — Both camps describe the same measured response. The bass shelf and upper-mid dip are real, so 'veiled' and 'muddy' are fair readings of the stock tuning; the 'balanced' camp hears the same shape as a pleasing consumer warmth. The app's EQ moves it a long way, and several positive reviews were written with it left flat while most negative ones end with an EQ preset.
“The Sony WH-1000XM5 have very good audio reproduction accuracy.”
RTINGS
“that frequency response is pretty uneven as we go from 20 to 20 khz. There are lots of ups and downs along the way that lead to, again, a particular, somewhat veiled and somewhat inaccurate sound character, if you really want to get picky about it.”
Tom Martin (The Absolute Sound)
