If you want wired over-ear headphones for exercise, choose audio-technica ATH-M30x; if you need true wireless earbuds with active noise cancellation, choose Cambridge Audio Melomania A100.
The M30x is the clearer fit for focused listening and monitoring, while the A100 is the more convenient choice when you want Bluetooth freedom and a charging case.

The ATH-M30x is a wired, over-ear headphone designed primarily for studio monitoring and mixing. Its listed frequency range is 15–22,000 Hz, and its sound-isolation design is aimed at helping listeners focus on audio. The product information also describes strong mid-range definition, which makes it a sensible option for work where vocal and instrument detail matters.
It is the more natural choice if you want headphones for a home listening setup, studio work, or field recording and prefer a direct wired connection. It includes a 6.35 mm jack, volume control, and a protective case. Those details point toward a headphone that can move between a desk and a recording location without relying on Bluetooth.

For exercise, the main question is whether you want an over-ear wired headphone at all. The M30x does not offer wireless freedom, so a cable may be inconvenient during movement. If your search is for foldable in ear headphones for exercise, this is not that kind of product: it is over-ear and wired. Choose it for its monitoring-focused design, not for a compact wireless workout setup.
The Melomania A100 is a true wireless in-ear option with Bluetooth connectivity, adaptive active noise cancellation, and a charging case. Its 10 mm dynamic drivers are paired with support for aptX Lossless and LDAC, while a seven-band adjustable EQ gives you a way to tailor the sound through the Melomania app. Those features make it the more flexible pick for someone who listens across different everyday settings.
The A100 is a better fit if you want to move without a headphone cable, switch between music and calls or controls through touch and app options, and adjust the sound to your taste. It comes with three sizes of silicone eartips, which gives you choices for fitting the earbuds. Its stated battery life is up to 39 hours with the charging case; that is a total-use figure, not a promise that the earbuds themselves run for that long on one charge.
For exercise, wireless earbuds are the more convenient format of these two. Still, the product details do not specify a sweat-resistance rating or a dedicated exercise fit, so I would not assume either. If you want the best wireless bluetooth headphones for exercise from this particular pairing, the A100 is the more plausible choice because it is wireless and in-ear—not because the listed specifications guarantee a secure fit for every workout.
• Best for a wired monitoring setup → audio-technica ATH-M30x. Its intended use includes studio monitoring and mixing, and it connects through a 6.35 mm jack.
• Best for Bluetooth freedom → Cambridge Audio Melomania A100. It connects wirelessly and does not have a headphone jack.
• Best for adaptive active noise cancellation → Cambridge Audio Melomania A100. The M30x lists sound isolation, which is a different approach from active cancellation.
• Best for a protective case included → audio-technica ATH-M30x. Its listed included items include a protective case and adapter plug.
• Best for app-based sound adjustment → Cambridge Audio Melomania A100. Its seven-band EQ is adjustable through the Melomania app.
• Best for a listed 39-hour battery figure → Cambridge Audio Melomania A100. That figure is stated for battery use with the charging case.
• Best for over-ear listening → audio-technica ATH-M30x. The A100 is an in-ear model with silicone eartips in three sizes.
• Best for the more practical exercise format → Cambridge Audio Melomania A100. Its wireless in-ear design avoids the cable, though the listed details do not establish sweat resistance or workout stability.
The two products answer different questions. The ATH-M30x is about a wired, over-ear listening and monitoring setup. The Melomania A100 is about compact wireless listening, with cancellation and EQ options. That distinction matters more than comparing driver sizes or frequency ranges alone: those numbers do not tell you which fit, connection style, or controls you will prefer while moving.
If your priority is sound work rather than workouts, the M30x has the more direct case. Its monitoring and mixing focus, wired connection, and over-ear layout suit a stationary or semi-portable setup. The A100 offers more everyday convenience, but its Bluetooth design and noise-cancelling features do not make it a studio-monitoring replacement by default.
The phrase “best head phones for exercise” can mean very different things: no cable, a particular fit, or the ability to block distractions. Among these two, the A100 answers the no-cable request, while the M30x offers a wired, over-ear alternative with sound isolation. Neither product’s supplied details establish a specific level of workout security, so fit preference should remain part of the decision.
My Verdict
I would choose the Cambridge Audio Melomania A100 for exercise because its in-ear Bluetooth design avoids the cable and adds adaptive active noise cancellation.
That is a format-based recommendation, not a claim that it is guaranteed to stay secure or handle sweat.
I would choose the ATH-M30x instead for wired monitoring, mixing, or focused over-ear listening.
For my exercise use, the A100 is the more practical of these two.
