Noise isolation (passive)

Memory foam tips create a deep physical seal that blocks a lot of outside noise even before the ANC engine starts working.

Passive isolation is excellent when fit is dialed in, supported by multiple tip and fin options and app-based fit testing. Reviews note that a strong physical seal meaningfully improves both perceived sound and ANC performance.

Plush over ear pads provide excellent passive isolation from high frequency noise, helping quiet planes and offices even before noise canceling is enabled.

Passive isolation is repeatedly described as improved versus prior WH-1000X models, with deeper pads and a stronger seal physically blocking a significant amount of incidental noise even before ANC engages. Several reviews note voices and office sounds are reduced notably from the seal alone, making the overall isolation feel very strong.

A snug over-ear fit and well-proportioned earcups create a strong passive seal that limits leakage and helps block external noise even before ANC kicks in. Several reviews highlight that this seal materially boosts perceived ANC performance in cafés, transit, and other everyday environments.

The earcups create a strong natural seal that blocks a meaningful amount of outside noise even before ANC is enabled; the snug fit supports both isolation and perceived low-end.

With a proper silicone tip seal, passive isolation is very effective for an earbud, reducing higher-frequency chatter enough to lower listening volume. Low-frequency rumble still leaks through more than highs, which is where ANC provides the larger benefit.

Dense, well-sealing ear pads and the closed-back design deliver strong passive isolation that significantly reduces engine and transit noise even before the ANC system engages.

A strong natural seal from the earcups provides much of the noise blocking before ANC, helping hush office and transit sounds effectively for the price.

Passive isolation benefits from the large oval/rect earcup shape, which covers the ears more fully and provides strong old-school noise reduction even before turning on ANC.

The included tips and stability bands create a solid seal that improves both isolation and ANC; fit is crucial, especially for smaller ears where the large shells may be harder to seal.

Good passive isolation when the seal is right, helped by foam-backed silicone tips; fit-dependent, but multiple reviews note it isolates well even before ANC is enabled.

Passive isolation from the large, over ear cups is strong enough to block much outside noise even before ANC, helping create a more sealed off listening bubble.

Plush over-ear pads provide a solid seal with minimal leakage and good passive attenuation, which helps reduce higher-frequency noise even before ANC is enabled.

Passive isolation is frequently described as helped by an easy-to-achieve seal and deep earcups, which also improves ANC performance. Several notes suggest that fit can vary with head shape or glasses, potentially reducing isolation if the seal is compromised. Overall, the PX7 S3 are presented as sealing well for most users, but not completely immune to individual fit differences.

Passive isolation is solid with a proper seal and meaningfully boosts overall attenuation. Incidental noises like tapping/keys can still be heard, just damped.

Passive isolation depends heavily on fit, but the nozzle shape, wings, and fit test help achieve a strong seal. With the right tips, physical attenuation is reported as meaningful even before ANC is applied.

Passive isolation is generally very good with the right tips, with foam tips often improving the seal further. Some smaller-ear users report seal leakage that reduces isolation and therefore also impacts ANC performance.

Foam-infused tips and a deeper fit can improve seal and passive attenuation, but results vary by ear shape and sweat, and it is not the same as true memory-foam isolation.

Passive isolation is generally strong when the seal is good, helping reduce outside noise even with ANC off. Seal quality and tip fit are key to achieving consistent isolation.

Passive isolation ranges from solid to inconsistent: when the fabric pads seal well, reviewers note effective attenuation that supports gaming focus and reduces room noise. However, the breathable material and a loose yoke fit can break the seal for some users, reducing real-world isolation and making results more variable than pleather-sealed headphones.

Passive isolation is solid for an over-ear and helps keep voices and general chatter down, but effectiveness depends on getting a good seal, and a looser fit can reduce both isolation and ANC performance.

Deep earcups and well-sealing fabric pads provide solid passive isolation for an over-ear ANC design and help reduce mid and high-frequency noise even before ANC is engaged; seal quality can vary with glasses and head shape, affecting isolation and ANC consistency.

Passive isolation ranges from modest to surprisingly effective: the breathable fabric pads generally isolate less than sealed leather or ANC models, but several reviewers still found it sufficient for household noise and even moderate traffic.

Passive isolation is decent for a lightweight closed-back headset, but the relaxed clamp and seal mean it is not the most cocooning until ANC is enabled; with ANC on, outside noise drops dramatically in typical homes and offices.

Passive isolation depends heavily on getting a full seal; the shallow/smaller earcups and eyeglasses can break the seal and reduce both isolation and bass, while a good fit noticeably improves attenuation.

Passive isolation is repeatedly described as modest and fit-dependent, with softer pads creating a gentler seal that lets more voices and higher-frequency noise through than top commuter headphones. As a result, ANC (and music playback) does much of the real isolation work, and some lab testing rates passive attenuation as weak for the price.
