Tested & Ranked: Proof of Which Sony Headphones Deliver the Best Sound and Anc
Out of the box, consumer Sony headphones adhere to a warm, bass-forward sound signature that diverges from the strict neutral Harman target. The WH-1000XM4 carries a prominent sub-bass boost around 60 Hz that bleeds into the lower midrange, resulting in thick, authoritative synth lines that can muddy vocal clarity in dense mixes. Its 40mm dynamic driver pushes immense air, but rapid acoustic transitions sometimes suffer from transient smear.
Sony re-engineered this approach on the WH-1000XM5 by switching to a smaller, stiffer 30mm carbon fiber composite dome. While bass volume drops slightly on paper, transient response improves substantially. Bass notes stop and start with tactile snap. The mid-range between 1 kHz and 4 kHz stays clearer, lending greater presence to acoustic guitars and female vocals.
You can reshape this tuning profile via the Sony Headphones Connect app. Its five-band graphic equalizer and "Clear Bass" slider allow users to carve out mid-bass mud without degrading lower-register impact. Setting Clear Bass to -2 and boosting the 1 kHz and 6.3 kHz sliders by +2 dB pulls the WH-1000XM5 close to a balanced studio monitor profile. Audiophiles running Android devices can enable LDAC codec support to stream 24-bit/96kHz audio at bitrates up to 990 kbps, unlocking micro-detail that AAC and standard SBC Bluetooth compress away.
