Instrument separation and imaging are consistently praised, with precise placement and clear spacing between layers even in complex mixes.

Multiple reviews point out LDAC is not supported, so LDAC-first Android users may need to choose a different model or use wired playback.

Even at higher volumes, the presentation stays largely clean and controlled, with low distortion noted in multiple reviews. The main caveat is that bass and treble emphasis can become more prominent if you listen loud.

Reviews that discuss loud listening report strong composure and minimal distortion at higher volumes, encouraging careful use because it stays clean as you turn it up.

Noise reduction on calls is effective at suppressing background noise, especially wind and street ambience in some demos. The tradeoff is occasional aggressive gating that can alter vocal tone.

Call quality is generally solid, with clear voice pickup and good intelligibility. In very noisy or windy conditions, some tests report the voice can sound a bit muffled or less natural than top performers like Sony or AirPods Max.

Midrange is generally clean and detailed, but multiple reviewers describe it as slightly recessed in the stock tuning; EQ can bring vocals forward. Others highlight the mids as a core strength for clarity and realism.

Midrange clarity is repeatedly highlighted as a standout strength, with clean layering and realistic vocal and instrument textures that feel unusually hi-fi for Bluetooth.

Multipoint is frequently praised as quick and seamless, with fast take-over when switching between phone and computer playback.

Multipoint is noted as supported and convenient for staying connected to two devices, though it is not heavily stress-tested across all sources.

Passive isolation benefits from an easy-to-achieve seal and helps overall noise reduction. A few notes suggest fit, glasses, or positioning can change results noticeably.

Passive noise isolation is described as strong thanks to large, well-sealing earcups and design details aimed at closing gaps around the ear, providing a solid foundation before ANC is even enabled.

Portability is mixed: the headphones lie flat and the case is slimmer than before, but they do not fully fold and can take more bag space than foldable rivals.

Portability is a recurring compromise: the headphones are large, do not fold down compactly, and several reviewers mention the case is too big for many backpacks.

True Sound and other presets are appreciated for a quick, consistent baseline, but reviewers note the preset lineup is not extensive and serious tuning relies on the manual EQ.

Preset sound modes are generally seen as well-judged: Hi-Fi is the reference setting for balance and clarity, while Bass mode adds punch and warmth, sometimes with a tradeoff in treble and mid presence.

Replaceable earpads are a notable plus for longevity, though some reviewers note replacement may require service or specific procedures.

Replaceable earpads are explicitly mentioned as a welcome premium touch, with pads that can be removed for cleaning or replacement.

Wear-detect and related sensors are commonly mentioned, with adjustability in the app and improved reliability versus older generations in some reports.
