If you want a wired, open-back planar magnetic experience for deep listening at home or in quiet studios while streaming high-resolution audio, choose HIFIMAN HE400se; if you need wireless freedom with active noise cancellation and a battery that lasts over four days of continuous playback, choose Cambridge Audio Melomania P100.
These two products sit on opposite ends of the headphone spectrum, serving fundamentally different needs. The choice isn't about which one sounds "better" in a vacuum, but rather which architecture fits your daily life and how you consume content. One is a tool for the dedicated listener who values pure sound quality above all else, while the other is a lifestyle device built for mobility and endurance.
• HIFIMAN HE400se: Delivers exceptional detail through its planar magnetic driver design with a lightweight, comfortable build, but requires a wired connection and offers no active noise cancellation.
• Cambridge Audio Melomania P100: Provides impressive 100-hour battery life, adaptive active noise cancellation, and wireless flexibility via Bluetooth, though it relies on dynamic drivers and a plastic enclosure.
• Who picks the HE400se?: Audiophiles seeking an immersive, studio-grade soundstage for stationary streaming sessions where silence is guaranteed.
• Who picks the Melomania P100?: Commuters, travelers, and active users who demand wireless convenience, long battery life, and the ability to block out ambient noise during their streams.
The HIFIMAN HE400se is engineered for a specific type of listener: someone who treats music as an event rather than background noise. Its core strength lies in the use of Stealth Magnet Technology paired with a planar magnetic driver. This configuration allows the diaphragm to move more uniformly than traditional dynamic drivers, resulting in a level of clarity and transient response that many enthusiasts find superior. The frequency response spans from 20Hz to 20kHz, covering the full audible spectrum without artificial boosting or cutting. When you are streaming high-bitrate tracks, this driver type ensures that every instrument retains its distinct texture and separation.

Comfort plays a massive role in why this headphone works for extended listening sessions. The design features bevelled ear pads that provide both noise isolation and temperature compensation, preventing the ears from overheating during long periods of wear. The headband has been optimized to distribute weight evenly, making the 385g (or 390g depending on the specific packaging variance) unit feel lighter than it actually is. The leather enclosure adds a premium tactile feel, while the over-ear shape ensures a secure seal that helps keep outside distractions at bay. However, this isolation is passive; there is no electronic magic here to actively cancel out a noisy train or office environment. You must be in a relatively quiet space to get the full benefit.
This product is ideal for anyone who wants to stream directly into a high-quality experience without the compression artifacts often associated with wireless transmission. The low impedance of 25 ohms and sensitivity of 91dB mean these headphones can be driven effectively by mobile devices, laptops, or portable players without needing a dedicated external amplifier, though a good source will always help. The versatility extends to its connectivity; the cable is replaceable, meaning you can upgrade the wire later if you wish to change the sound signature or durability. If your primary goal is to hear exactly what the artist intended when you hit play on a streaming service, and you don't mind being tethered to a jack, this is a compelling choice. It is not designed for the gym, the commute, or walking down a busy street.
In stark contrast, the Cambridge Audio Melomania P100 SE is built for the modern, on-the-go listener who refuses to compromise on battery life or connectivity. Its standout feature is the user-replaceable battery, which enables a staggering 100 hours of playback time. This is not a marketing fluff number; it translates to over four days of continuous listening on a single charge, or weeks of intermittent use before you ever need to plug in a charger. For someone who streams podcasts, audiobooks, or music throughout the workday and into the evening, this longevity removes the anxiety of finding a power outlet. The quick charge capability is equally practical: just five minutes of charging provides up to four hours of playtime, saving you from a dead battery situation in a pinch.
Wireless performance is where this model truly shines. Equipped with Bluetooth 5 and support for aptX Lossless, it transmits high-resolution audio at 24bit/96kHz without the typical degradation found in standard Bluetooth codecs. This makes it a serious contender for those looking for the best earbuds for streaming who cannot carry wires everywhere. The inclusion of Adaptive Active Noise Cancellation means you can tune out the hum of an airplane engine or the chatter of a coffee shop, creating a personal bubble wherever you go. Additionally, the Wear Detect sensor automatically pauses your stream when you take the headphones off, adding a layer of convenience that wired models simply cannot offer.
The design philosophy here prioritizes utility and sustainability. The plastic enclosure is durable and lightweight, weighing 0.7 kg for the complete package including the case. The system includes a carrying case, USB-C charging cables, and a 3.5mm jack cable for wired fallback if the battery runs dry or you prefer a direct connection. The 10-ohm impedance and dynamic driver type deliver a sound profile that is punchy and adaptable, enhanced by DynamEQ technology which adjusts the equalization based on your volume settings. If you need the best sports earbuds for streaming because you need them to stay put and handle movement, or if you are looking for sleep headphones for streaming where comfort and battery life are paramount, the P100 SE is the logical choice. It is a companion for life outside the house, ready to adapt to your schedule.

I would buy the Cambridge Audio Melomania P100 for my daily life because I am constantly moving, and the 100-hour battery life combined with active noise cancellation solves problems I face every day. The ability to stream lossless audio wirelessly without worrying about running out of power is a game-changer for a busy schedule. However, if I were setting up a dedicated listening station in a quiet room to focus purely on the sonic details of a new album release, I would switch to the HIFIMAN HE400se. For general streaming purposes where convenience and endurance matter most, the Cambridge Audio is the clear winner in my opinion.
