Pros

• Battery 4.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 4.7
  Battery life is a standout: many users see around 60–65 hours with ANC on and about 100 hours with ANC off, though some report closer to ~40 hours with ANC depending on settings and codecs.
• Audio-video sync accuracy 4.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.6
  Video playback is generally well synchronized with little noticeable lag, and low-latency or gaming modes (when available) help keep streaming and mobile games in sync.
• Bluetooth connectivity stability 4.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.5
  Single-device Bluetooth connections are usually stable with surprisingly long range, though some users report occasional pairing quirks and range/consistency can drop when multipoint is enabled.
• Portability/foldability 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.4
  Foldable earcups and the included hard case make the headphones easy to pack and protect in a bag when commuting or traveling.
• USB-C 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.4
  Uses a USB-C port on the earcup for charging, making it easy to top up with common cables and chargers.
• Charging 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.4
  USB-C charging is quick, with full charges typically around 70–80 minutes, and fast-charge top-ups are very strong—roughly 5–10 hours of playback from about five minutes depending on settings.
• Ear cup swivel/rotation range 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.4
  Earcups rotate and fold flat for storage and can swivel for more comfortable neck-wear, though case fit may prefer a specific folding orientation.
• Headband adjustability 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.4
  Headband extension offers plenty of range with positive notched clicks, fitting larger heads and helping maintain a stable seal.
• Comfort during long use 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.4
  Most reviewers find them very comfortable for hours thanks to light weight and generous padding, but comfort can vary with clamping force and pleather heat buildup during long sessions.
• Included accessories 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.3
  Ships with a hard carry case, USB-C charging cable and 2.5mm-to-3.5mm audio cable with mic, which together add strong overall value.
• Bass performance 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.3
  Punchy, energetic bass with good depth and generally controlled impact, but it leans toward mid-bass warmth and can occasionally blur kick drums or feel a bit undetailed without EQ tweaks.
• Wired connection sound quality 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.3
  Using the wired connection tightens the presentation and reveals extra low-level details compared with standard Bluetooth listening.
• Maximum volume clarity 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.2
  At higher volumes the drivers generally avoid obvious distortion, but pushing loudness can reduce detail and bass can smear separation, especially in noisy settings where you max out volume.
• Noise isolation (passive) 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.2
  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.
• Weight comfort 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.1
  At roughly 246–255g the headphones feel light for over-ears, though a few users notice headband weight distribution and occasional headband-heavy feel.
• Carry case quality 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.0
  A protective hard or zippered case is usually included and helps travel durability, but internal organization varies and some reviewers consider the case more basic or downgraded versus earlier models.
• Sound quality 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.0
  Warm, bass-forward V-shaped tuning with generally clear highs and good detail for the price; LDAC or wired listening can add clarity, but resolution and spaciousness trail premium models and some listeners notice a slight veil or muddle in complex tracks.
• Ear cup padding quality 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.0
  Earcups use plush memory-foam style padding that seals well and supports long listening, though the pleather can run warm and feel sweaty for some users.
• Hinge durability 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.0
  Hinges and joints generally feel stable with decent rigidity, but some units exhibit creaks or slight rattle when handled, reflecting their budget build.
• Active noise cancellation effectiveness 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 10 reviews 3.9
  ANC is strong for the price and works best on low-frequency rumble from buses, trains and planes, plus office hum, but it can leave some chatter through, add a faint hiss/white noise, and may feel inconsistent in very loud or impact-heavy situations.
• LDAC 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.9
  LDAC can improve perceived detail and clarity when it successfully engages, but device compatibility is inconsistent and some phones may default to AAC/SBC or fail to switch to LDAC.
• Design and Aesthetics 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.9
  The headphones have a clean, understated look with a matte finish and slightly angled cups that read more premium than the price, though some colorways and styling can feel generic.
• Codec support 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.8
  Supports SBC and AAC plus LDAC for compatible devices, and also offers wired analog listening via a headphone-side 2.5mm jack using the included 2.5mm-to-3.5mm cable.
• Equalizer customization 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.8
  EQ options are a strong value point when available, with multi-band adjustment and multiple presets to rein in bass or boost mids, though some app versions offer more limited or preset-only control.
• Midrange clarity 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.8
  Vocals and instruments stay reasonably clear and natural for the price, but the mids can sit slightly behind the bass and may sound a bit recessed or edgy until you tweak EQ.
• Multipoint connectivity reliability 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.8
  Multipoint is supported but sometimes hidden as an experimental setting; some users have smooth laptop+phone switching, while others find pairing a second device finicky or needing re-enabling after power cycles.
• Preset EQ profile quality 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.8
  Presets are generally useful and varied enough to change the signature without wrecking balance, but names can be gimmicky and some built-in sound loops or extra modes feel poorly implemented.
• Transparency mode quality 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.7
  Transparency mode is handy for quick conversations and staying aware outdoors, though quality varies—some find it very natural, while others notice hiss and a slightly artificial sound.
• Clamping force comfort 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.7
  Clamping force is mixed—some find it light and prone to shifting, while others feel it’s tighter than expected—so fit comfort depends on head size and preference.
• Build quality 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.7
• Treble clarity 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.7
  Treble is mostly smooth and non-harsh with decent detail, though some users find it rounded or slightly dark with limited sparkle compared with higher-end headphones.
• Microphone noise reduction 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.7
  Noise reduction helps keep speech understandable in offices and in light wind, but background sounds aren’t fully removed and occasional wind or room noise still comes through.
• Voice assistant integration 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.7
  Voice assistant access is available via button shortcuts, but the multi-function button behavior and chime-based feedback can make it less intuitive than dedicated controls.
• Microphone quality for calls 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.6
  Call quality is generally intelligible for casual use, but voices can sound a bit grainy, sibilant or unnatural and performance falls short of dedicated boom mics or premium headsets.
• Instrument separation 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 3.6
  Instrument separation is decent for the price, but denser mixes can sound a little congested and less airy than on higher-end models.
• App 3.5 ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 3.5
  App support can be confusing across versions (1More app vs older 1More Music), but once connected it provides EQ, mode toggles, firmware updates and extras; the interface is often described as dated or clunky with key items like multipoint buried in submenus.
