If you want a closed, foldable headphone with a long cord for focused study sessions, choose Sony MDR7506; if you need swiveling earcups and a lighter listed weight for DJ-style handling, choose Reloop RH-2500. For studying, I’d lean toward the Sony: its closed-ear design is specifically described as reducing external noise, while the Reloop’s clearest advantage is its rotating construction.
Neither model is a Bluetooth headphone or an earbud. Both are wired, over-ear options, so the real choice is between Sony’s long, non-detachable cord and noise-reducing design and Reloop’s swivel-and-fold build.
• Sony MDR7506: A closed-ear design, 40 mm drivers, folding construction, and a 9.8-foot cord; the cord is not detachable.
• Reloop RH-2500: Rotating, folding construction, one-sided cord routing, and a listed weight of 150 g; the supplied details do not specify a noise-reduction feature.
• Sony is for: Students who want a wired, closed-ear headphone for a desk or recording setup and value a long cable.
• Reloop is for: DJs and listeners who want earcups that rotate and fold for handling and storage.
• My pick for studying: Sony MDR7506, because its stated closed-ear design is the more direct fit for blocking out some surrounding noise.
The Sony MDR7506 is an over-ear, wired headphone built around a closed-ear design. Sony describes that design as reducing external noise, which makes it a sensible fit for studying in a shared room, working through recorded lectures, or listening to audio while nearby activity carries on. It uses 40 mm drivers and neodymium magnets, and the listed frequency range is 10 Hz to 20 kHz.
The practical details matter, too. The headphone folds for storage and comes with a soft case. Its 9.8-foot cord gives you room to move around a desk or sit back from a connected device, but it is not detachable. A 1/4-inch adapter is included alongside the gold-plated plug. That setup suits someone who expects to use a wired connection, not someone seeking wireless convenience.

I’d choose the Sony for a student who mainly studies at a desk and wants a closed, foldable headphone with a long cable. I’d skip it if a detachable cable is essential, or if you are specifically searching for Bluetooth earbuds, touch controls, or a gaming headset. The Sony is an over-ear wired headphone, not any of those things.
For someone moving between listening positions or working with DJ equipment, rotating earcups are a concrete advantage. The supplied details also identify 3.5 mm and 6.3 mm stereo connections. Its listed frequency response is 20 Hz to 20 kHz, and its sensitivity is 118 dB ±3 dB at 1 kHz (1 mW). Those figures help describe the product, but they do not by themselves establish how it will sound to every listener or in every room.
For studying, the Reloop can still make sense if you want a wired over-ear headphone and value its lighter listed weight or rotating earcups. The trade-off is that its information does not specify a noise-reduction feature comparable to the Sony’s stated reduction of external noise. I’d favor it for a buyer whose listening routine includes DJ-style handling, rather than someone whose main priority is studying amid distractions.
• Best fit for studying in a noisy shared space → Sony MDR7506. Its closed-ear design is explicitly described as reducing external noise. That is the clearest study-focused distinction between the two.
• Best for a long reach from your device → Sony MDR7506. Its 9.8-foot cord gives more stated cable length, though it cannot be detached.
• Best for rotating earcups → Reloop RH-2500. The rotating construction is useful for DJ-style handling and is a specific feature the Sony description does not list.
• Best for one-sided cable routing → Reloop RH-2500. Its cord runs from one side, which may appeal if you prefer a single cable hanging away from both sides of your workspace.
• Best for compact storage with a soft case included → Sony MDR7506. It folds and comes with a supplied soft case. The Reloop also folds, but its provided details do not list a case.
• Best for someone who needs a detachable cord → Neither based on the supplied details. The Sony cord is explicitly non-detachable, and no detachable-cable feature is given for the Reloop.
• Best for choosing from the stated driver and frequency details → Sony MDR7506. Its 40 mm drivers and 10 Hz–20 kHz range are specified. The Reloop lists a 20 Hz–20 kHz response but does not provide a driver size here.
• Best for Bluetooth listening, touch control, or in-ear use → Neither. Both are wired, over-ear headphones. If you are looking for the best Bluetooth earbuds for studying or touch control in ear earbuds for studying, these products do not match that form factor.
The gaming question is similar. If you are searching for the best gaming headset for studying, keep in mind that neither product is identified as a gaming headset, and the provided details do not describe a microphone or gaming-specific controls. They may serve as wired headphones for listening, but I wouldn’t choose either on the assumption that it includes features not listed here.
My Verdict
I’d choose the Reloop RH-2500 instead if rotating earcups and one-sided cord routing matter more than the Sony’s stated noise reduction. For my study-focused priorities, Sony is the more straightforward fit.
I’d choose the Sony for studying if reducing some surrounding noise is a priority, because its closed-ear design is described as reducing external noise. The Reloop is a reasonable alternative if you value rotating earcups and a listed weight of 150 g.
Neither is presented as a Bluetooth headphone. Both are wired, over-ear models, so choose between them based on their cable and construction features rather than wireless use.
No. Its 9.8-foot cord is described as non-detachable. A 1/4-inch adapter is included, but that does not change the cable’s fixed connection.
The Reloop RH-2500 has rotating, folding construction and one-sided cable routing, features that suit DJ-style handling. The Sony also folds, but its listed advantages lean more toward a closed-ear design, a long cord, and supplied storage case.
