P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones
4.0
ANC effectiveness is mixed across sources: some call it very good and close to leaders, while others measure it as clearly behind top Bose and Sony options, especially for tougher noise scenarios. ANC adjustability is widely praised thanks to sliders, adaptive behavior, and app-driven profiles and zones that let you tune isolation versus awareness.
Android compatibility
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones

Clamping force comfort
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
4.6
Clamping force is usually described as gentle and well-judged; the comfort-focused clamp can reduce stability for vigorous movement.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones
4.5
Clamp force is often described as moderate and comfortable, but the lighter clamp can trade off with stability during movement-heavy activities.
Codec support
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
4.3
Codec support centers on SBC/AAC plus Snapdragon Sound with aptX Adaptive/Lossless on compatible devices; Bluetooth 5.3 and LE Audio readiness are mentioned, though rollout varies.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

Equalizer customization
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
2.9
EQ is available but limited (often described as a 3-band slider with modest sensitivity), so deep tuning is not a strength.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

Even when pushed loud, multiple reviews note the sound stays clean, but the practical ceiling can feel lower than expected compared to peers.
Microphone noise reduction
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
4.0
Noise reduction for calls is often effective in busy environments, but some tests still capture background announcements or office noise.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

Noise isolation (passive)
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
4.4
Large, plush pads create a strong seal that boosts passive isolation and supports the overall noise-reduction performance.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones
3.2
Passive isolation is a recurring weak point in several lab-style reviews, sometimes attributed to a softer seal; others find it adequate in real travel use.
Portability/foldability
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
4.6
Fold-up-and-flat portability is a key advantage, helping the headphones and case take up less space than some rivals.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

Preset EQ profile quality
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
3.3
Preset EQ profiles exist (for example bass/treble focused presets), but the selection and granularity are limited compared with rivals.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

Soundstage is above average for closed-back ANC headphones, and Immersive Audio can widen it further with varying success.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones
4.2
Soundstage is usually described as wide enough for an immersive feel, but depth can be limited and some tests describe the stage as more inside-the-cups than truly expansive.
Spatial audio
P1
Product 1: Bose QuietComfort Ultra Wireless Headphones
3.0
Immersive/spatial audio can widen the presentation for some content, but many find it inconsistent or overly processed and note the battery hit.
P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones

P2
Product 2: Sennheiser MOMENTUM 4 Wireless Headphones
4.3
Weight is typically reported around the 290g range and perceived as manageable, though not the lightest in class and still a factor for ultra-long sessions for some users.
