• Cambridge Audio Melomania A100 — biggest strength: fully wireless with Adaptive Active Noise Cancelling, aptX Lossless and LDAC support, plus up to 39 hours of battery with the charging case.
• Cambridge Audio Melomania A100 — biggest trade-off: it's a Bluetooth in-ear with a plastic enclosure and no wired jack, so it depends on charging and pairing rather than a plug.
• Sony MDR-M1 — biggest strength: a closed acoustic structure with high sound isolation and ultra-wideband playback from 5 Hz to 80 kHz, built for precise monitoring.
• Sony MDR-M1 — biggest trade-off: it's wired only, with no Bluetooth, no noise cancelling and no battery — it needs a device with a 3.5 mm or 6.3 mm jack.
• Choose the Melomania A100 if you want portable, cable-free listening with app-based tuning and noise cancelling.
• Choose the MDR-M1 if you're producing, mixing or monitoring and need isolation, accuracy and a replaceable cable.
The Melomania A100 is a true wireless in-ear built around a 10 mm dynamic driver, and Cambridge Audio's pitch is hi-fi-grade sound in a form factor you can carry anywhere. The spec sheet backs up the ambition: aptX Lossless and LDAC both appear, so the earbuds can take advantage of higher-quality Bluetooth codecs when your source supports them. A 7-band adjustable EQ in the Melomania App means you can shape the sound yourself rather than accepting a fixed tuning. Frequency response is listed at 20 Hz to 20,000 Hz, which covers the full audible range.
The practical story is convenience. Adaptive Active Noise Cancelling adjusts to your surroundings, which makes these earbuds a natural fit for commuting, open-plan offices, flights and gym sessions. Battery life is quoted at up to 39 hours with the charging case, and wireless charging means you can drop the case on a pad instead of hunting for a cable. Touch controls handle playback, and there's support for Siri and Google Assistant. Three sizes of silicone eartips ship in the box, so you can get a decent seal, and the package includes a USB-C to USB-C cable, a quick start guide and a two-year manufacturer warranty.
Who should buy it: anyone who wants one pair of earbuds for music, calls and travel, and who values codec quality and app-based EQ over absolute neutrality. Who should skip it: if you need a wired connection to an interface or mixer, or you want a monitor you can trust for critical mixing decisions, this isn't that product. There's no headphone jack here — Bluetooth only. Also, if you'd rather not think about charging at all, a wired headphone sidesteps the issue entirely.
The Sony MDR-M1 is a closed-back, over-ear professional reference monitor, and everything about the design points at studio work. The closed acoustic structure with high sound isolation is there so you can track and monitor without the room bleeding in and without your audio bleeding out into a live mic. The frequency range is the headline number: 5 Hz to 80 kHz, described as ultra-wideband playback, with a driver unit designed to balance low distortion against reproduction across that span. Whether or not you can hear 80 kHz, the design intent is accurate, low-distortion reproduction from the bottom of the spectrum upward.
Sony says the tuning was developed in collaboration with industry engineers to accurately reproduce creative intent — a claim about voicing philosophy rather than a magic trick. Practically, the MDR-M1 is built for long sessions: soft, thick earpads, and a weight of roughly 216 grams, which is light for an over-ear monitor. Maintenance is clearly part of the brief. You get two detachable cables in different lengths, the cable attaches with a screw system for a secure connection, earpads are replaceable, and a screw-in adapter lets you switch between 6.3 mm and 3.5 mm jacks. Warranty is 90 days limited.
Who should buy it: producers, engineers, podcasters, musicians tracking in a room, and anyone who wants a wired, isolated, serviceable headphone for critical listening. Who should skip it: if you want wireless freedom, noise cancelling or a battery, none of that exists here. It's wired, it has sound isolation rather than active cancellation, and it needs a source with a real headphone jack. If your phone has no jack, you'll need an adapter or a different device.

In my opinion, the right answer depends entirely on whether you need to move or you need to monitor. If you want one pair of earbuds for music, travel and calls, I'd buy the Cambridge Audio Melomania A100 — the combination of Adaptive ANC, aptX Lossless and LDAC, app EQ and up to 39 hours with the case makes it the more versatile everyday pick. If your work is audio production and you need isolation, accuracy and a cable you can replace, I'd buy the Sony MDR-M1 instead. They aren't competitors so much as two different tools. Buy the one that matches your day.
FAQ
They're built for different purposes. The Melomania A100 is a wireless in-ear with ANC, codec support and app EQ; the MDR-M1 is a wired closed-back studio monitor with ultra-wideband playback. "Better" only makes sense relative to how you'll use them.
No. The MDR-M1 is wired only, connecting via a 6.35 mm or 3.5 mm jack, and it uses a closed acoustic structure for sound isolation rather than active noise cancelling. There's no battery and no wireless mode.
Cambridge Audio lists up to 39 hours of battery life with the charging case. The case also supports wireless charging, so you can top it up on a charging pad.
The Sony MDR-M1, clearly. Its closed-back design, sound isolation, 5 Hz–80 kHz range, detachable cables and replaceable earpads are all aimed at production and monitoring. The Melomania A100 is a listening product, not a reference monitor.
