How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, DJ-focused tool with pivoting earcups built for one-ear cueing, choose Hercules HDP DJ45; if you need a wireless, all-day Bluetooth headset for travel and calls, choose MZYDM Headphones Over Ear.
• Hercules HDP DJ45 — biggest strength: a closed-back, circumaural design with rotating earpieces, a spiral cable that stretches from about 3.3 feet to over 6.6 feet, and a 1/4-inch adapter for pro gear.
• Hercules HDP DJ45 — biggest trade-off: it's wired only, weighs 0.6 kg, and is tuned around 60-ohm DJ monitoring rather than casual wireless listening.
• MZYDM Headphones Over Ear — biggest strength: Bluetooth 5.3 with a claimed 60-hour average battery life, a 3-hour charge time, and a foldable lightweight frame with a travel pouch.
• MZYDM Headphones Over Ear — biggest trade-off: 20-ohm impedance and 94 dB sensitivity mean it's built for convenience and streaming, not for isolating stage-level monitoring.
• Who each pick is for: Hercules for DJs and wired-critical listeners; MZYDM for commuters, travelers and phone-first users.
The Hercules HDP DJ45 is a purpose-built DJ headphone, and that shows in every design choice. The earpieces are circumaural, meaning they encircle your ears rather than sit on top of them, which is the better starting point for sound isolation. That matters when you're standing next to a monitor or in a loud room and still need to hear your cue track clearly. The soft padding on the earpieces and under the headband is there to keep pressure off your ears during long sets.
The feature I'd point a DJ to first is the rotating earpiece design. It lets you flip one cup off your ear for comfortable one-ear monitoring while the other stays sealed — the standard way to beatmatch against a room. The cable runs on one side only, which keeps it out of your way, and the spiral cable adjusts from roughly 3.3 feet up to more than 6.6 feet when extended. That range is genuinely useful: short enough to stay tidy, long enough to move around. You also get both a 1/8-inch / 3.5 mm stereo jack and a 1/4-inch / 6.35 mm stereo jack adapter, so it plugs into laptops, phones and DJ mixers without hunting for a dongle.
On audio, the specs list a 60-ohm impedance, a dynamic driver, and a 20 Hz – 20 kHz frequency range. The 60-ohm rating is the interesting number: it's high enough to be a deliberate load, but low enough that it still plays loudly from ordinary sources. The enclosure is metal and plastic, the color is black, and the weight is listed at 0.6 kg, so it feels like a tool rather than a featherweight. Controls cover volume and sound isolation, and the control method is remote — meaning adjustment lives on the cable, not on the cups.
Buy it if you're a DJ, a bedroom mixer, or a wired-only listener who wants rotating cups and a coiled cable. Skip it if you want Bluetooth, a microphone for calls, or something you can toss in a bag without a thought — this is a wired headphone with a specific job.
The MZYDM Headphones Over Ear is the opposite philosophy: convenience first. It's a wireless over-ear headset running Bluetooth 5.3 with a stated range of 10 meters. That means you can leave your phone on a desk or in a bag and walk around a room without the cable tugging at you. The stated average battery life is 60 hours with a 3-hour charge time, which is the kind of number that changes how you use a headphone — you stop thinking about charging it every night and just top it up occasionally.
The audio specs describe a dynamic driver with a 20 Hz – 30,000 Hz frequency range, 20-ohm impedance and 94 dB sensitivity. Read those together and you get a headphone that's easy to drive: low impedance plus high sensitivity means it gets loud from a phone or tablet without a headphone amp. The extended treble figure is a spec-sheet claim about range, not a guarantee of tuning, but the low-impedance design is a real, practical advantage for casual listening. There's also a 3.5 mm jack listed, so wired listening is available as a fallback — handy on a plane seat-back screen or when the battery is flat.
Physically, it's over-ear with silicone in the enclosure material, black, and described as foldable and lightweight. It ships with a travel pouch, which tells you who it's aimed at: people who pack a headphone in a backpack and want it protected. Controls are push-button with button control, covering sound isolation. The age range is listed as teen, and the warranty is 30 days, which is worth knowing before you commit — it's a shorter coverage window than the Hercules.
Buy it if you want wireless freedom, long battery, a built-in mic for calls, and a foldable frame for travel. Skip it if you need one-ear monitoring, a coiled cable, or the kind of isolation a closed-back DJ cup is designed to deliver.
Side-by-Side: Which Should You Choose?
• Best for DJ monitoring and one-ear cueing → Hercules HDP DJ45. Rotating earpieces and a one-sided coiled cable exist for exactly this.
• Best for long sessions away from a charger → MZYDM Headphones Over Ear. The 60-hour average battery life with a 3-hour charge dwarfs what any wired-only set can offer.
• Best for plugging into a mixer or pro interface → Hercules HDP DJ45. The included 1/4-inch / 6.35 mm adapter and 3.5 mm jack cover both ends.
• Best for sound isolation by design → Hercules HDP DJ45. A closed-back circumaural build with soft padding is the more isolating architecture of the two.
• Best for travel and packing → MZYDM Headphones Over Ear. Foldable, lightweight, and supplied with a travel pouch.
• Best for calls and streaming → MZYDM Headphones Over Ear. The microphone and button controls make it a phone-first headset.
• Best for durability confidence → Hercules HDP DJ45. Metal-and-plastic construction and a 1-year warranty versus a 30-day warranty.
In my opinion, these two aren't really competing — they're two different jobs. If you're a DJ or you want a wired headphone with rotating cups, a coiled cable and a 1/4-inch adapter, I'd buy the Hercules HDP DJ45. Its whole design is aimed at performance, and the 1-year warranty backs that up. If you're a commuter, student or traveler who wants Bluetooth, a mic, a foldable frame and a 60-hour battery, I'd buy the MZYDM Headphones Over Ear — just go in knowing the warranty is short. Buy for the job you actually have.
Foldable headphones are over-ear models whose earpieces fold or pivot so the whole thing collapses into a smaller shape for storage and transport. Both picks here qualify: the Hercules uses pivoting earpieces, and the MZYDM is described as foldable and lightweight with a travel pouch.
The exact motion depends on the hinge design. On a pivoting style like the Hercules HDP DJ45, you rotate the earpieces flat against the headband; on a foldable travel set like the MZYDM, the cups fold inward toward the headband. Always fold along the joint the manufacturer built in — don't force a cup past its stop.
Most folding-headphone faults are at the hinge, the cable or the pads. Check the pivot for a cracked or loose joint before anything else, then inspect the cable where it enters the cup — the Hercules runs its cable on one side only, so that's the first place to look. If the hinge itself has snapped, it's usually a replacement rather than a repair.
For pure travel convenience, I'd pick the MZYDM: it's wireless, foldable, lightweight and comes with a travel pouch. The Hercules folds too, but it's a 0.6 kg wired headphone with a coiled cable — better suited to a DJ booth than a seat-back tray.
