If you want foldable, over-ear wired headphones for gym sessions in a loud space, choose Amazon Renewed Audio-Technica ATH-M30x; if you need a studio-focused package with a long cable and a 6.3 mm adapter, choose Audio Technica Studio Monitor. For the gym, I lean toward the Renewed model’s compact, collapsible design and straightforward fit.
Neither is wireless or noise-cancelling: both are wired, closed-back headphones designed for sound isolation. That makes them a different kind of choice from long battery life kids headphones for gym, the best active noise cancelling true wireless earbuds for gym, or bluetooth open ear headphones for gym. These two are over-ear studio-style options, so the deciding factors are portability, cable setup, and the specific model details.
• Amazon Renewed Audio-Technica ATH-M30x: 40 mm drivers, mid-range detail, circumaural isolation, and a collapsible frame. The trade-off is that it is a renewed product, not a new one.
• Audio Technica Studio Monitor: Similar 40 mm driver design and isolation, plus a 3.0 m straight cable and a 6.3 mm screw-on adapter. The trade-off is a long cable that may be cumbersome for casual, mobile use.
• For either pick: The wired, over-ear design suits stationary listening and loud environments better than workouts that call for wireless freedom.
• Choose the Renewed ATH-M30x if compact storage and a simple gym-bag carry matter most.
• Choose the Studio Monitor if you want the listed studio-use accessories and published electrical specifications.
The Renewed ATH-M30x is an over-ear, wired headphone with 40 mm dynamic drivers. Its tuning is described as emphasizing detail and mid-range definition, while the circumaural earcups are designed to help isolate sound in loud surroundings. The cable exits from one side, and the headphones fold down for easier storage.
That combination makes sense for someone who wants a basic, portable wired pair for a gym bag, a shared room, or listening near noisy equipment. A 3.5 mm jack is specified, and the listed weight is 7.8 ounces. Because the product is renewed, the listing describes it as pre-owned or refurbished and professionally inspected and tested. It also states that renewed products are eligible for replacement or refund under the Amazon Renewed Guarantee if the buyer is not satisfied.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I would skip this model if you need Bluetooth, a built-in battery, active noise cancellation, or the freedom to move without a cable. It is also not the right fit if buying a new product is a firm requirement. Its portability comes from a folding design, not from wireless operation.
The Audio Technica Studio Monitor is also a wired, collapsible, circumaural headphone with 40 mm dynamic drivers and a closed-back design. Its listed use cases include studio tracking, mixing, and field recording. The package details specify a 3.0 m straight cable with a left-side exit, a protective carrying pouch, and a screw-on 6.3 mm adapter.
Those details make it the more clearly documented studio-oriented option of the pair. The adapter can suit equipment with a 6.3 mm headphone connection, while the long cable can be useful when the listener needs room to move around a desk or recording setup. Its published specifications include a 15–22,000 Hz frequency response, 47-ohm impedance, and 96 dB sensitivity. The listed weight is 220 g, without cable and connector.
For a gym, the long cable is the main practical drawback. It may be more cable than you want around exercise equipment, and the listing does not describe wireless operation or active noise cancellation. If your priority is moving freely while working out, neither model addresses that need; if you want wired headphones and value the included adapter and pouch, this one has the more explicit studio setup.
• Best for compact storage → Amazon Renewed Audio-Technica ATH-M30x. Its collapsible design is stated directly, making it easier to pack away between gym visits or work sessions.
• Best for a studio setup with a 6.3 mm connection → Audio Technica Studio Monitor. It includes a screw-on 6.3 mm adapter; the Renewed model lists a 3.5 mm jack.
• Best for a shorter, unspecified cable setup → Amazon Renewed Audio-Technica ATH-M30x. Its sheet confirms a single-side cable exit but does not specify cable length, so I would not assume it is short. Check the actual listing details if cable length is decisive.
• Best when a long cable is useful → Audio Technica Studio Monitor. Its included straight cable is 3.0 m, which can suit a desk or recording area but may be awkward at the gym.
• Best for buyers focused on gym portability → Amazon Renewed Audio-Technica ATH-M30x. Both fold, but the listed package details for the Studio Monitor include a long cable that could take more managing during a workout.
• Best when you want stated studio use cases → Audio Technica Studio Monitor. Its product details explicitly name tracking, mixing, and field recording.
• Best for sound isolation in a loud environment → Either. Both are circumaural designs described as providing isolation; neither is specified as active noise cancelling.
• Best for a new-product requirement → Neither based on these listings. The Renewed ATH-M30x is identified as pre-owned or refurbished, while the Studio Monitor sheet does not establish new-product status.
The core sound and construction descriptions overlap substantially: both specify 40 mm drivers, mid-range detail, over-ear circumaural fit, and a collapsible design. So I would not choose between them on the assumption that one has dramatically different sound quality. The more useful distinction is what comes with the Studio Monitor and how the renewed status affects your preference.
My Verdict
I would choose the Amazon Renewed Audio-Technica ATH-M30x for gym use if I wanted wired, foldable over-ear headphones and was comfortable buying a renewed product. Its portability and sound-isolating design fit that use better than a studio package built around a 3.0 m cable.
If my listening were mostly at a desk or recording setup, I would choose the Audio Technica Studio Monitor for its stated studio applications and included 6.3 mm adapter. For gym sessions, though, I would rather carry the simpler, collapsible option.
No. Both are described as wired headphones. Neither product sheet lists Bluetooth, a battery, or wireless playback.
In my opinion, the Renewed ATH-M30x is the more practical of the two for a gym bag because it folds and its listed details do not specify the Studio Monitor’s 3.0 m cable. Both remain wired, so neither offers cable-free movement.
No active noise cancellation is specified for either model. Both use an over-ear circumaural design described as providing sound isolation, which is not the same feature as active noise cancelling.
Is the Audio Technica Studio Monitor worth choosing over the renewed ATH-M30x?
