Several reviewers highlight target-curve or reference-leaning balance and good tonal accuracy. Fit and seal still matter, with small positioning changes affecting bass and lower-mid response.
Pros: Battery, Equalizer customization
Cons: Xbox compatibility, Water/sweat resistance rating
Reviewers consistently describe the tonal balance as natural, balanced, or close to reference in the better presets, with cleaner frequency relationships than the original Bathys.
Pros: Build quality, Instrument separation
Cons: LDAC, Touch control responsiveness
Measurements and listening impressions generally align on a well-tuned response for broad appeal, with small deviations (notably bass lift) that can be refined via EQ.
Pros: Battery, aptX
Cons: LDAC, Water/sweat resistance rating
Hi-Fi mode is commonly described as balanced and relatively uncolored, while Bass mode shifts the tonality warmer and can slightly reduce upper-mid and treble prominence.
Pros: Maximum volume clarity, Replaceable earpads
Cons: App, Equalizer customization
Reviews often describe the tuning as flat, neutral, smooth, or monitoring-oriented, emphasizing that little is overhyped.
Pros: Wired connection sound quality, 3.5mm analog input availability
Cons: Travel friendliness, Sound leakage
The sound is described as largely accurate.
Pros: Microphone quality for calls, Comfort during long use
Cons: aptX, Water/sweat resistance rating
Tuning is usually characterized as close to neutral with a touch of warmth or bass lift; a couple of reviews suggest the default EQ can feel a bit restrained until...
Pros: Replaceable earpads, Replaceable battery
Cons: Water/sweat resistance rating, Touch control responsiveness
Tonal balance is often described as slightly warm rather than strictly neutral; DynamEQ and the SE retune can shift bass/treble balance, so accuracy depends on settings.
Pros: Battery, Replaceable battery
Cons: LDAC, Water/sweat resistance rating
Tonality is often described as balanced or smooth rather than strictly neutral, with a coherent frequency integration that avoids obvious bloat. Some characterize it as tastefully colored (warm-bright/W-shaped) rather than...
Pros: Sustainability materials, Replaceable earpads
Cons: Noise isolation (passive), Portability/foldability
Tonal balance is described as neutral-with-warmth by several outlets, while others report noticeable swings and a more consumer-friendly curve. Overall, it is closer to balanced than purely V-shaped, but not...
Pros: aptX, Multipoint connectivity reliability
Cons: Replaceable battery, LDAC
Reviews describe the tuning as relatively natural or accurate on suitable material, even if not all listeners rank it top of class.
Pros: Battery, Connectivity options
Cons: Water/sweat resistance rating, Replaceable earpads
Frequency accuracy is not described as reference-grade; one review says fine detail and precision are not the last word.
Pros: Bluetooth version, Battery
Cons: Water/sweat resistance rating, Wind noise handling
Tonality can be shaped into a more balanced response with CustomTune and light EQ, but out of the box many characterize it as a V-shaped or slightly dark consumer tuning...
Pros: Android compatibility, Multi-platform compatibility
Cons: Water/sweat resistance rating, Dongle
Tonal accuracy is decent but not reference grade, with several listeners hearing a consumer-friendly tuning and others noting scratchiness or uneven balance.
Pros: USB-C, Award recognition
Cons: Water/sweat resistance rating, Sidetone adjustment quality
Overall balance is commonly described as cohesive, with a bass-forward tilt; the most critical voices cite some veil or mild imbalance on dense mixes.
Pros: Audio-video sync accuracy, USB-C
Cons: Water/sweat resistance rating, Carry case quality
Tuning is widely described as more balanced than older Beats, but still stylized with boosted lows and bright highs rather than strict neutrality. Purist listeners may prefer a more accurate,...
Pros: Design and Aesthetics, Multi-platform compatibility
Cons: aptX, LDAC
Review evidence is generally positive for frequency response accuracy, though comments are sometimes context-dependent.
Pros: Premium feel, Award recognition
Cons: aptX, LDAC
Frequency balance is not especially accurate. Reviewers often heard boosted bass, dipped mids, or sharp or rolled-off treble, although a few still found the overall tuning enjoyable.
Pros: Battery, Charging
Cons: Carry case quality, Sensors
Frequency response accuracy is not a priority here: multiple reviews describe a built-in V-shaped or bass-forward curve that does not fully conform to neutral targets even with presets.
Pros: Battery, Cable quality
Cons: aptX, LDAC
Impressions suggest an overall agreeable tuning, but not strictly reference-flat; fit and Adaptive EQ can shift the response.
Pros: Hinge durability, Transparency mode quality
Cons: aptX, LDAC
Measured and subjective impressions frequently point to a non-neutral stock response (often described as dark), with EQ being the practical path to a more accurate balance.
Pros: LDAC, Equalizer customization
Cons: Replaceable battery, Sustainability materials
Frequency response accuracy is described as consumer-tuned rather than neutral, with boosted bass and some upper-range shaping that not everyone enjoys.
Pros: Volume output, Weight comfort
Cons: aptX, LDAC
Tonal balance is the product's biggest sonic debate, ranging from balanced after tuning to muddy, bass-heavy, or uneven depending on reviewer and setup.
Pros: Bluetooth connectivity stability, Comfort during long use
Cons: Included accessories, Cable quality
Frequency balance is polarizing: some call it even-handed, while measurement-driven reviews point to large deviations (bass and treble boosts and a vocal region dip).
Pros: aptX, Battery
Cons: Frequency response accuracy, Clamping force comfort
Measured frequency response was criticized for deviating notably from the reviewer’s preference curve.
Pros: Battery, Connectivity options
Cons: Active noise cancellation, Transparency mode quality
