Cambridge Audio Melomania P100 Headphones

Verdict

If you care most about rich, revealing sound, huge battery life, and premium build, the Melomania P100 are one of the strongest wireless over-ear options under $300. You do trade off some comfort due to weight and clamp, plus only okay transparency and fussy wear detection, but the combination of hi-res codecs, effective ANC, and excellent wired and wireless performance makes them a compelling buy for audio-focused listeners.

Pros

  • Battery 4 reviews 5.0
    Real world longevity backs the claim of around 60 hours with ANC and up to 100 hours without, with some users going weeks of moderate daily listening between charges, making it ideal for long trips and train delays plus quick top ups via USB C.
  • Sound quality 4 reviews 5.0
    Energetic yet natural tuning with crisp detail and convincing spatial imaging, delivering a bright but balanced sound that feels tonally correct and engaging across genres and is often said to rival or beat far more expensive ANC headphones.
  • Build quality 3 reviews 5.0
    Premium fit and finish with sturdy aluminum hardware, durable vegan leather pads and a replaceable battery, plus well executed plastics and tight construction tolerances that make the P100 feel more expensive and longer lived than many rivals.
  • Replaceable earpads 1 review 5.0
    User replaceable earpads let owners refresh worn cushions instead of replacing the entire headphone, supporting both comfort over time and the P100's sustainability-focused design.
  • Replaceable battery 3 reviews 4.8
    A user replaceable internal battery significantly extends the service life of the headphones compared with typical sealed ANC models, fitting the product's ecological and longevity focused concept.
  • Charging 2 reviews 4.8
    Fast USB C charging can deliver several hours of listening from just a few minutes on the cable, helping to keep the large battery topped up without requiring long spells tethered to a charger.
  • Codec support (AAC 3 reviews 4.7
    Support for AAC and aptX Adaptive enables higher quality wireless audio on both iOS and many Android devices, helping the P100 take better advantage of modern Bluetooth sources than basic SBC only designs.
  • Ear cup padding quality 3 reviews 4.7
    Soft vegan leatherette earpads with slow reacting memory foam provide a comfortable, secure seal around the ears, contributing significantly to long session comfort while maintaining a premium, cool feeling surface.
  • Midrange clarity 3 reviews 4.7
    Reviews highlight clear, expressive mids that give vocals and instruments their own space, preserving articulation and musicality without sounding recessed or disconnected from the rest of the mix.
  • Sustainability materials 3 reviews 4.7
    Use of vegan leatherette, user replaceable earpads and a replaceable internal battery gives the P100 a more sustainable, long lived design than many sealed ANC rivals that must be discarded when parts wear out.
  • Equalizer customization 4 reviews 4.6
    A seven band EQ with useful presets and the ability to save custom profiles allows meaningful tonal tweaks, though several reviewers find the default tuning so well judged that they rarely feel the need to adjust it.
  • Treble clarity 4 reviews 4.6
    High frequency instruments such as cymbals and tambourines sound crisp and articulate, with clear, consonant vocals that preserve detail in the top end without becoming piercing at normal listening levels.
  • Bass performance 4 reviews 4.5
    Bass is full, deep and slightly elevated yet remains well controlled, giving rhythms impact and drive without overwhelming the midrange, though it stops short of the ultra hard hitting, club like slam some electronic music fans might seek.
  • Design and Aesthetics 4 reviews 4.5
    Understated, upmarket design with aluminum accents, integrated branding and tidy finishes that echo the look of higher end audiophile models, helping the P100 stand out from plainer plastic competitors at this price.
  • Microphone quality for calls 3 reviews 4.5
    The integrated microphones deliver clear call quality for both sides of the conversation, with speech intelligibility that can rival some boom mic headsets and no obvious echo or heavy processing artifacts.
  • Bluetooth pairing speed 2 reviews 4.5
    Pairing is quick and straightforward, with the headphones automatically reconnecting to known devices and multipoint making it easy to move between phone and computer without manual intervention.
  • Multipoint connectivity reliability 2 reviews 4.5
    Multipoint connectivity works dependably to keep the P100 connected to two devices at once, allowing seamless switching between, for example, a laptop and a phone without repeated manual pairing.
  • Preset EQ profile quality 2 reviews 4.5
    Factory EQ presets such as Blues, Electronic, Natural, Rock and Voice are thoughtfully tuned for their intended genres, offering quick, sensible tonal changes without dramatically distorting the headphone's overall character.
  • Wired connection sound quality 2 reviews 4.5
    Using the USB C or analog cable provides a modest but noticeable boost in fidelity and dynamic nuance over standard Bluetooth playback, making the most of high quality recordings and hi res sources.
  • Cable quality 1 review 4.5
    The supplied USB C and 3.5 mm cables use sturdy, woven jackets that resist tangling and feel more durable than the thin rubber leads often bundled with competing headphones.
  • Headband adjustability 1 review 4.5
    An infinitely adjustable headband lets users dial in fit for different head sizes, and once set the sliders tend to hold their position well, supporting consistent comfort and seal over time.
  • Instrument separation 1 review 4.5
    The P100 present mixes with strong separation between instruments, making it easy to distinguish melodies, percussion and backing parts even in dense arrangements, which contributes to their engaging, hi fi character.
  • Bluetooth connectivity stability 3 reviews 4.3
    Bluetooth 5.3 provides a stable wireless connection with typical range and obstacle performance, pairing cleanly with modern smartphones and supporting reliable multipoint links without frequent dropouts or glitches.
  • Included accessories 3 reviews 4.3
    A protective hard case and both USB C and 3.5 mm audio cables are included in the box, covering travel and wired listening needs without forcing buyers to purchase basic accessories separately.
  • Soundstage width 3 reviews 4.3
    Soundstage is moderately wide with convincing depth and focus, preferring a realistic studio or small venue perspective over exaggerated width while still avoiding a closed in, in head presentation.
  • App 4 reviews 4.3
    Melomania Connect adds a seven band EQ with presets, ANC and transparency controls, a gaming low latency mode, wear detection and firmware updates in a simple app that most users only need occasionally after initial setup.
  • Button control usability 4 reviews 4.3
    Physical buttons for power, volume, playback and ANC transparency are clearly laid out and easy to find by touch, avoiding accidental triggers and making day to day control very straightforward.
  • Multi-platform compatibility 2 reviews 4.3
    These headphones pair smoothly with Android, iOS and desktop platforms while supporting major streaming services, making them a flexible option for listeners who regularly switch between different device ecosystems.
  • Noise cancellation adjustability 2 reviews 4.3
    Three ANC strengths, typically labeled Low, Medium and High, let listeners adjust how much external noise is removed for commuting, office or home listening without dramatically altering the core sound signature.
  • Active noise cancellation effectiveness 4 reviews 4.0
    ANC remains effective and adjustable for daily use, offering smooth, natural attenuation that works especially well on planes and trains, though it still trails Bose, Sony and other top tier models for total isolation and can sound slightly uneven in very windy street noise.
  • USB-C 3 reviews 4.0
    The USB C port handles both charging and digital audio, working seamlessly as a USB sound device on Android and Windows devices even if compatibility can be more limited on some Apple hardware.
  • Microphone noise reduction 2 reviews 4.0
    Callers generally hear the user clearly while most background chatter and traffic noise is reduced to a low level, though sharper high frequency sounds can still cut through on occasion.
  • Voice assistant integration 1 review 4.0
    On ear controls can trigger the phone's voice assistant reliably, and the microphones pick up commands clearly enough that voice control feels like a practical way to manage playback and basic tasks.
  • Carry case quality 3 reviews 3.8
    The molded hardshell case feels sturdy and protective with an internal pocket and magnetic cable storage, and while it is slim and well made it still occupies more space in a bag than the most compact travel cases.
  • Comfort during long use 4 reviews 3.6
    Plush pads and a generally well judged fit keep many listeners comfortable for extended sessions, although the 330 g weight, clamp and warming earpads can still cause fatigue or hot spots for some over longer listening, so all day comfort depends on head shape and tolerance.

Cons

  • Clamping force comfort 3 reviews 3.3
    Clamping force has been described as relaxed by some but uncomfortably tight by others, with the grip varying by head shape and sometimes creating noticeable pressure on the ears and skull during longer listening sessions.
  • Transparency mode quality 3 reviews 3.2
    Transparency mode lets outside sound in and works reliably for basic situational awareness, but voices and announcements can sound a bit muffled, so it is less impressive than the very best awareness implementations.
  • Weight comfort 2 reviews 3.0
    The relatively heavy 330 g chassis can weigh on the head and neck for some listeners, but others find the mass and clamping force reasonably well judged for a full size ANC design, so perceived comfort varies depending on fit preferences and sensitivity to weight.
  • Portability/foldability 1 review 2.5
    These over ear headphones do not fold especially small and their sturdy hard case occupies a noticeable amount of space in a bag, making them less ideal for travellers who prioritise compact packing.
  • Stability 1 review 2.5
    The relaxed clamp and loose fit feel comfortable but mean the P100 can shift or loosen during vigorous movement, making it less suited to sports or very active use than to everyday commuting and home listening.
  • Spatial audio 3 reviews 2.0
    The P100 do not currently support any spatial or virtual surround audio modes, which may disappoint buyers who prioritise immersive movie or gaming features offered by some competing headphones.
  • Sensors 1 review 2.0
    On ear detection can pause playback when the headphones are removed but behaves inconsistently enough, with occasional delays or missed triggers, that some users prefer to disable the sensor in the app.
