How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, hard-wearing pair of DJ-style headphones that folds down small and stays comfortable through a long club or booth session, choose Reloop RH-2500; if you need a studio reference headphone with a wider frequency range, a long coiled cable and replaceable earpads for recording, broadcast and home-studio work, choose Sony MDR7506.
• Reloop RH-2500 — biggest strength: a genuinely closed, swivel/fold-in DJ design that is light on the head (150 g) with high output capacity and precise, punchy bass.
• Reloop RH-2500 — biggest trade-off: it is built and voiced for DJ monitoring, with a narrower 20 Hz–20 kHz range, no carrying case mentioned and no replaceable-pad spec.
• Sony MDR7506 — biggest strength: a long-standing studio reference design with 40 mm neodymium drivers, a wider 10 Hz–20 kHz range, a 9.8 ft non-detachable cord and replaceable earpads.
• Sony MDR7506 — biggest trade-off: it weighs more (227 g), the cable is fixed rather than detachable, and the closed on-ear fit is aimed at isolation rather than DJ cuing swivel.
• Who the Reloop is for: DJs, mobile jocks and anyone who wants a light, folding, closed-back cue headphone.
• Who the Sony is for: producers, engineers, podcasters and home-studio users who want one dependable reference pair.
The RH-2500 is the successor to the RH-2450 line, and Reloop's own framing of it is telling: a completely closed construction that pushes bass reproduction further than before. That matters in a DJ context, where you are cueing a kick drum against a room that is already loud. The spec sheet backs the intent up — a dynamic driver, 32 ohm impedance, 118 dB ±3 dB sensitivity at 1 kHz, and a 20 Hz–20 kHz range. In plain terms, that combination of low impedance and high sensitivity means it does not need much of a push from a phone, controller or mixer output to get loud.
Physically, this is a DJ headphone first. The earcups rotate and fold in, which is the feature that lets you flip one cup off your ear to hear the booth while the other keeps cueing. The headband is a redesigned, lighter construction, and at 150 g it is the lighter of the two here — worth caring about if you wear headphones for hours at a time. The cord is routed one-sided using oxygen-free copper strand, which keeps it out of the way of your mixing hand, and you get both a 3.5 mm stereo link and a 6.3 mm stereo link, so it plugs straight into a controller or a mixer without an adapter hunt.
Who should buy it: working DJs, mobile DJs, and anyone who wants a closed, folding, over-ear can that is easy to throw in a gig bag and easy to drive from modest gear. The 1-year warranty and sturdy construction suit regular transport. Who should skip it: if your job is critical listening — mixing a record, editing dialogue, checking reverb tails — a DJ-voiced headphone is the wrong tool. The RH-2500 is tuned for impact and clarity in a noisy room, not for the flattest possible reference. Nobody should buy it expecting a detachable cable either, because that is not part of the design. And if you want to know what it costs today, check the current price on Amazon rather than guessing.
The MDR7506 is one of the few headphones in this category that has been part of studio life for decades, and the specs explain why people keep coming back to it. You get 40 mm drivers with neodymium magnets, a 10 Hz–20 kHz frequency range, 63 ohm impedance and 106 dB sensitivity. That wider low-end reach and the higher impedance point to a headphone designed to be fed by proper studio gear — an interface, a mixer, a field recorder — where a bit more voltage is available and the reward is a stable, balanced soundstage.
The closed-back design is the other half of the story. Sony describes earcups that fully cover the ear, cutting ambient noise and stopping sound from leaking out into an open microphone. If you have ever tracked vocals or a podcast with a pair of leaky headphones, you know why that matters. The fit is on-ear with soft synthetic leather pads, an adjustable band and padded swivel earcups, and the pads are replaceable — a real long-term advantage, because pads are the first thing to wear out on any headphone.
Then there is the cable, and it is a love-it-or-hate-it detail. It is 9.8 feet, ends in a gold-plated plug, is not detachable, and comes with a 1/4-inch adapter. Nine-point-eight feet is a lot of reach in a control room; it is also a lot of cable to manage at a desk, and if it ever fails you cannot just swap it. Included in the box are a soft case, the Unimatch 3.5 mm/6.3 mm adaptor, and a bundle that adds a headphone case and an enhanced protection pack. The weight is 227 g.
Who should buy it: recording and mixing engineers, broadcast and film/TV people, podcasters, and home-studio owners who want one headphone that behaves predictably across all of those jobs. Who should skip it: anyone who wants the lightest possible can, a detachable cable, or DJ-style rotating cups for one-ear cuing. And again, for cost, look at the current price on Amazon — this page does not quote figures.
• Best for DJ cuing and one-ear monitoring → Reloop RH-2500. The swivel/fold-in cups are built for exactly that.
• Best for critical listening and mixing → Sony MDR7506. A wider 10 Hz–20 kHz range and 40 mm neodymium drivers are the studio-reference recipe.
• Best for long sessions on weight alone → Reloop RH-2500 at 150 g, versus 227 g for the Sony.
• Best for isolation from outside noise → Sony MDR7506. The closed, fully ear-covering cups are designed to block ambient sound and prevent leakage into a mic.
• Best for easy storage and travel → both fold, but the Sony ships with a soft case, and the bundle adds another.
• Best for cable reach → Sony MDR7506 with its 9.8 ft cord; the Reloop's one-sided OFC routing is tidier for mixing hands but shorter.
• Best for long-term ownership → Sony MDR7506, because the earpads are replaceable, so you are not throwing the whole headphone away when the foam flattens.
• Best for low-impedance, easy-to-drive use → Reloop RH-2500 at 32 ohm and 118 dB sensitivity, which plays loud off modest sources.
• Best if you value a detachable cable → neither. The Sony's is fixed, and no detachable cable is specified for the Reloop.
In my opinion, the Sony MDR7506 is the one I would buy for recording-studio work, because it is the more versatile tool: a wider frequency range, 40 mm neodymium drivers, strong isolation, a long cable for a control room, and replaceable pads that let you keep it alive for years. The Reloop RH-2500 is a better DJ headphone than the Sony is a DJ headphone — lighter, folding, low-impedance and voiced for punchy cueing — so if that is your actual job, buy the Reloop and don't look back. But for recording, broadcast, podcasting and home-studio use, the Sony is the safer single pair to own. Before you decide, check the current price on Amazon for both and let that settle any tie.
FAQ
In a studio, closed-back headphones like these two let an engineer or artist monitor a mix without the sound bleeding into a live microphone, and let a performer hear a click track or backing mix while recording. The Sony MDR7506's closed, ear-covering design is specifically aimed at that isolation job, while the Reloop RH-2500's closed cups and swivel design also suit one-ear DJ-style monitoring.
Good studio headphones need a closed design for isolation, a balanced response, and enough durability to survive daily use. Both of these qualify: the Sony brings 40 mm neodymium drivers, a 9.8 ft cable and a soft case; the Reloop brings a sturdy closed build, one-sided oxygen-free copper cord routing, 118 dB sensitivity and a 3.5 mm plus 6.3 mm link.
For a home studio, I would lean toward the Sony MDR7506, mainly because of the wider 10 Hz–20 kHz frequency range, the 9.8 ft cord that reaches across a desk to an interface, and replaceable earpads that make it a longer-term purchase. The Reloop RH-2500 is the better pick if your home setup is DJ-focused and you want a lighter, easier-to-drive closed headphone.
