If you want wired, closed-back headphones for general listening and monitoring, choose Shure SRH240A; if you need a foldable studio design with a replaceable cable, choose AKG Pro Audio K275. For the gym, neither has a stated wireless or active-noise-cancelling feature, so I would choose based on fit, cable handling, and how you plan to use it.
Shure SRH240A vs AKG Pro Audio K275 at a Glance
• Shure SRH240A: 40 mm drivers, padded over-ear cups, and a closed-back design; its attached cable cannot be detached.
• AKG Pro Audio K275: Foldable closed-back build, 50 mm drivers, and a replaceable cable; its listed connection is wired, not wireless.
• Shure suits: General listening and monitoring at home, especially when you want a supplied 1/4-inch adapter.
• AKG suits: Studio work and portable wired listening, particularly if folding the headphones away is useful.
• For gym use: Both are wired over-ear headphones, so neither sheet supports a claim of cable-free convenience or active noise cancellation.
The SRH240A is a closed-back, over-ear headphone built around 40 mm neodymium dynamic drivers. The stated use is general listening and monitoring, and the described sound aims for full bass with clear mids and highs. That makes it a sensible option for someone who wants one wired pair for everyday listening as well as home recording, rather than a design focused on folding up for travel.
Its padded headband and ear cups are intended to support a comfortable over-ear fit. The closed-back cups also provide passive noise reduction, which can help limit some surrounding sound without electronics. The cable is a 2-meter straight lead attached to the headphones, so there is no need to manage a separate detachable cable, but a damaged or inconveniently placed lead cannot simply be unplugged. The included 1/4-inch adapter gives the 3.5 mm plug another connection option.
Who should skip it: Skip the SRH240A if you specifically want a foldable frame or a replaceable headphone cable. Its cable is permanently attached, and the data does not describe a folding mechanism.

AKG Pro Audio K275: Who It's For
The K275 is also a closed-back, over-ear wired headphone, but it puts more emphasis on portability and studio use. Its 50 mm transducers are described as supporting extended low-frequency reach and detailed bass reproduction, while the intended presentation is transparent and defined. Those qualities make it worth considering for editing or mixing, where hearing distinctions between parts matters more than simply emphasizing bass.
Its frame folds through a multi-axis hinge, and the hinge is metal. The cable is replaceable, which offers a useful maintenance advantage over a permanently attached lead. The design also includes slow-retention foam ear pads and a self-adjusting headband. Together, those details point to a headphone intended for repeated use and easier storage, although the sheet does not provide a folded size or specific comfort measurements.
The K275’s stated 32-ohm impedance and high sensitivity are relevant if you expect to use it with a lower-powered mobile device. The product description says that combination supports strong output before distortion, but it does not make the headphones wireless or remove the practical limits of a cable. For a gym bag, the foldable design is a real convenience; for a workout, the over-ear form and wired connection remain important considerations.
• For general listening and home monitoring → Shure SRH240A. Its stated purpose covers both, with 40 mm dynamic drivers and a closed-back fit.
• For editing or mixing with detailed bass in mind → AKG Pro Audio K275. Its 50 mm transducers are described as supporting extended low frequencies and clearer bass detail.
• For a headphone that folds for storage → AKG Pro Audio K275. Its three-axis hinge lets the frame collapse.
• For a replaceable cable → AKG Pro Audio K275. That is a clear practical advantage if cable replacement matters to you.
• For an included 1/4-inch adapter → Shure SRH240A. It comes with a 6.35 mm threaded adapter for its 3.5 mm plug.
• For a permanently attached, straight 2-meter cable → Shure SRH240A. That length may work well at a desk, but the lead cannot be detached.
• For use with lower-powered mobile devices → AKG Pro Audio K275. Its low impedance and sensitivity are specifically presented as helpful for that use.
• For gym listening → neither is an obvious cable-free choice. Both are wired, over-ear headphones; choose only if that setup fits your workout and the cable will not get in your way.
Searches for the “best head phones for gym” often mix wired over-ear models with wireless workout products. These two belong in the wired category based on their listed connections. Neither data sheet specifies a battery, wireless connection, water resistance, or active noise cancelling. That means shoppers searching for “best active noise cancelling true wireless earbuds for gym” are looking for a different type of product, not a feature offered by either headphone here.
Think first about where the cable will go. The Shure’s fixed 2-meter lead can be convenient when you sit near a recording device, but it cannot be unplugged for storage or replaced independently. The AKG’s replaceable cable is easier to swap if needed, and its folding frame can make it easier to put away. Neither detail alone makes one headphone right for every setup; it depends on whether your priority is a straightforward desk connection or easier packing and cable maintenance.
For sound use, the descriptions suggest different emphases rather than a simple winner. Shure presents the SRH240A for everyday listening and monitoring, with bass, mids, and highs described as clear and balanced in broad terms. AKG describes the K275 in studio-reference language, with attention to defined sound and detailed low frequencies. These are manufacturer descriptions, not a substitute for listening yourself, so I would match them to your intended task instead of assuming driver size alone determines sound quality.
Comfort and isolation also deserve a practical check. Both models are closed-back and over-ear, and both are described as providing isolation or reducing background sound. The Shure sheet mentions padded cups and headband; AKG lists slow-retention foam pads and a self-adjusting headband. Neither sheet specifies sweat resistance or fitness-focused construction. If you want long battery life kids headphones for gym, neither is a match for the battery-life part of that search: both are wired, and no battery feature is listed.
If price is part of your decision, check the current price on Amazon rather than relying on an outdated figure. I would also compare the connection you need: Shure includes a 1/4-inch adapter, while the AKG listing specifies a 3.5 mm jack and a replaceable cable. Those small setup details can matter more than a headline feature when you are choosing headphones for a particular device.
My Verdict
Neither is specified as a wireless or fitness-focused headphone. Both are wired, closed-back, over-ear models, so consider whether a cable is practical for your workout before choosing either.
The AKG Pro Audio K275 has a replaceable cable. The Shure SRH240A has an attached 2-meter cable that is not detachable.
No active noise-cancelling feature is listed for either model. Both are closed-back designs with passive sound isolation or noise reduction.
The AKG K275 folds, while no folding feature is listed for the Shure SRH240A. The AKG’s replaceable cable also gives it a practical advantage for cable maintenance.
