How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a closed-back studio headphone built for long sessions with three detachable cables and a carry case in the box, choose Heil Sound Pro Set 3; if you need a lightweight folding DJ headphone with swivel earcups and very high sensitivity for cueing and mixing, choose Reloop RH-2500.
• Heil Sound Pro Set 3 — biggest strength: A complete studio kit out of the box: three twist-lock detachable cables (1.8 m straight, 1.8 m straight with a 3.5 mm plug, and a 3 m coil), a gold-plated screw-on 1/8″-to-1/4″ adapter, ear cushions, and a protective case.
• Heil Sound Pro Set 3 — biggest trade-off: It's the heavier of the two at 16 ounces, and the design is built around sitting still at a desk, not folding down for a gig bag.
• Reloop RH-2500 — biggest strength: A swivel/fold-in DJ design at just 150 g, with 118 dB sensitivity and a rated 1,000 mW-class high output capacity that suits loud cueing in a booth.
• Reloop RH-2500 — biggest trade-off: You get one cable with one-sided routing and no case or spare cords, and its 20 Hz–20 kHz range is narrower than the Heil's 10 Hz–22 kHz.
• Who each pick is for: Heil Sound Pro Set 3 for studio, podcast, broadcast and live-sound work where you stay put and want cable options; Reloop RH-2500 for DJs and mobile mixing who need to fold, swivel and travel light.
The Heil Sound Pro Set 3 is a closed-back, over-ear headphone with a dynamic neodymium driver, a 32-ohm impedance rating, a 10 Hz–22 kHz frequency response, 102 dB sensitivity and a 1,000 mW maximum input. Read those numbers together and a picture forms: this is a headphone designed to be driven by everyday studio and broadcast gear while still taking a healthy amount of level without complaint. The 10 Hz bottom end is unusually deep for a closed-back monitoring headphone, which is why the listing leans on "deep bass" language — useful when you're checking kick drum weight, room rumble or the low end of a podcast voice.
What really separates it, though, is the accessory load. Three detachable cables ship with it, all twist-lock, all terminating in a 1/8″ (3.5 mm) plug with a gold-plated screw-on 1/4″ (6.3 mm) adapter. In a real studio that matters more than it sounds. You can leave the 3 m coil cord on the desk for tracking and reach across the room without yanking the plug, keep the 1.8 m straight cord for editing at the computer, and use the iPhone/iPod-compatible 1.8 m cord when you're checking a rough mix on a phone. The protective case and spare ear cushions mean the headphone survives being thrown in a bag between sessions.
Reloop RH-2500: Who It's For
The Reloop RH-2500 is a professional DJ headphone first and a monitoring headphone second, and the spec sheet says so plainly. It's a closed, over-ear design with swivel and fold-in construction — the earcups rotate so you can flip one against your ear for cueing while the other stays on, and the whole thing folds down small. At 150 g it's dramatically lighter than the Heil, and Reloop states that weight reduction plus a new headband construction was a deliberate comfort play over the earlier RH-2450 series.
The audio numbers tell their own story. Sensitivity is rated 118 dB ±3 dB at 1 kHz (1 mW) — very high, which means it gets loud from modest sources. Frequency response is 20 Hz–20 kHz, and the description promises precise bass, clean mids and clear treble, framed around previewing and mixing. The one-sided oxygen-free copper cord keeps the cable out of your way on one side, and you get both a 3.5 mm and a 6.3 mm stereo link, with a 1.05 m cable length. The connectivity field lists Bluetooth alongside wired — worth noting, but the headline feature set here is wired DJ cueing, so I'd treat it as a wired headphone for practical purposes.
Where it gives ground: there's no carry case, no spare cable, and no volume control or noise control listed. The 20 Hz–20 kHz range is narrower at both ends than the Heil's 10 Hz–22 kHz, which is fine for DJ work but less useful if you're hunting sub-bass detail. In my opinion this is the headphone for DJs, mobile DJs, and anyone mixing on the move who needs to fold the headphones into a gig bag and cue loudly in a noisy room.
Side-by-Side: Which Should You Choose?
• Best for long seated sessions → Heil Sound Pro Set 3. Over-ear cushions, a 16 oz frame and a stated focus on avoiding headphone fatigue over hours.
• Best cable flexibility → Heil Sound Pro Set 3. Three detachable twist-lock cables plus a gold-plated screw-on 1/4″ adapter, versus one one-sided cord on the Reloop.
• Best for loud cueing in a noisy booth → Reloop RH-2500. 118 dB ±3 dB sensitivity and a stated high output capacity, versus 102 dB on the Heil.
• Best low-end extension on paper → Heil Sound Pro Set 3. 10 Hz–22 kHz versus 20 Hz–20 kHz.
• Best for DJ mixing and turntable work → Reloop RH-2500. Swivel cups, one-sided cord routing and a DJ-first design brief.
• Best for podcast, broadcast and voice work → Heil Sound Pro Set 3. Closed back, sound isolation, a remote volume control and a protective case.
• Best travel kit in the box → Heil Sound Pro Set 3. Case, ear cushions and multiple cables included; the Reloop ships as the headphone and cable only.
For a recording studio, I'd buy the Heil Sound Pro Set 3. My reasoning is simple: the three detachable cables, the screw-on 1/4″ adapter, the protective case and the wider 10 Hz–22 kHz range map directly onto studio life, where you're swapping between an interface, a console and a phone, and where the headphone mostly lives on a desk. The Reloop RH-2500 is a genuinely good DJ headphone — lighter, more sensitive, and folding — but those strengths serve a booth, not a control room. If you split your time between DJing and studio work, the Reloop is the more versatile one on the move. If the studio is the job, the Heil is the one I'd reach for.
what is the use of headphones in recording studio
In a studio, closed-back headphones like these let you monitor a mix, track a performance, and hear your own voice or instrument without the sound bleeding into a live microphone. The Heil Sound Pro Set 3 adds sound isolation and a remote volume control, which is exactly what you want when a mic is open in the room.
what are the best recording studio headphones
There's no single answer, because "best" depends on your job. For seated studio and broadcast work I'd point to the Heil Sound Pro Set 3, thanks to its closed back, 10 Hz–22 kHz range, 1,000 mW maximum input and three detachable cables. For DJ and mobile cueing, the Reloop RH-2500's swivel design and 118 dB sensitivity make more sense.
what are good studio recording headphones
Good ones are closed-back, comfortable for long sessions, and able to take level without distortion. Both of these are 32-ohm, over-ear dynamic designs. The Heil Sound Pro Set 3 leans toward studio use with a case and multiple cables; the Reloop RH-2500 leans toward DJ use with a folding 150 g frame.
what are the best home studio headphones
For a home studio, cable options and comfort usually decide it. The Heil Sound Pro Set 3 gives you a 1.8 m straight cord, a 1.8 m phone-compatible cord and a 3 m coil cord, plus ear cushions and a case — in my opinion the more useful package for a desk-based home setup. The Reloop RH-2500 is the better choice if your home setup doubles as a DJ rig.
