How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want serious over-ear monitoring for DJ work, mixing or any situation where you need to shut the room out, choose Hercules HDP DJ45; if you need a coordinated school set for a 5–8 year old girl — backpack, foldable headphones, lunch bag and pencil case in one box — choose Similove Kids Backpack. These two products share almost nothing except the word "headphones," and that is exactly why this comparison matters: they are bought by completely different people for completely different reasons.
• Hercules HDP DJ45 — biggest strength: A closed-back, circumaural DJ design with pivoting earpieces, a one-side spiral cable that extends from about 3.3 feet to over 6.6 feet, and 60-ohm dynamic drivers rated 20 Hz–20 kHz.
• Hercules HDP DJ45 — biggest trade-off: It is a wired, single-purpose tool. No wireless, no carry case mentioned, and a 0.6 kg weight that you feel on longer casual listens.
• Similove Kids Backpack — biggest strength: A four-piece matching set (15-inch backpack, foldable kids headphones, insulated lunch bag, pencil case) in a purple flower design, sized for ages 5–8 and rated waterproof in a lightweight polyester build.
• Similove Kids Backpack — biggest trade-off: It is a children's school set, not audio gear. The headphones are foldable and kid-friendly, but nothing in the specs positions them for monitoring, isolation or adult listening.
• Buy the Hercules HDP DJ45 if you are a DJ, a bedroom producer, or anyone who wants one-ear cueing and strong passive isolation from a wired over-ear pair.
• Buy the Similove Kids Backpack if you are a parent or grandparent shopping for a girl starting primary, kindergarten or elementary school and you want one coordinated, ready-to-go bundle.
The HDP DJ45 is built around one idea: keep the outside world out and let you hear your cue mix. The closed-back, circumaural design means the earpieces encircle your ears rather than sit on top of them. That matters practically — over-ear cups with soft padding on the earpieces and under the headband rest against your head instead of pressing down on your ears. If you have ever worn on-ear headphones through a three-hour session, you know why that distinction shows up in the spec sheet.
The DJ-specific features are the real story here. The cable runs on one side only, which frees your other hand during a set, and it is a spiral cable that adjusts from roughly 3.3 feet up to more than 6.6 feet when extended — short enough to stay out of the way at the booth, long enough to reach across a desk or a controller. The earpieces rotate, which is what makes one-ear monitoring comfortable: you swing one cup back, cue the next track with your free ear, and swing it back. The same pivoting design lets you fold and turn the earpieces so the headphones pack down for transport.
On the audio side, the 60-ohm impedance is a genuinely useful number. It is low enough that a phone, laptop or controller output can drive these to a powerful level without a dedicated amp, but high enough that they are not a fragile, hiss-prone pair. The dynamic drivers cover 20 Hz to 20 kHz, the full audible range. You get both output formats out of the box — a 1/8-inch / 3.5 mm stereo jack plus a 1/4-inch / 6.35 mm stereo jack adapter — so the same pair plugs into a phone and into a mixer or interface without hunting for a dongle. There is also a volume control on the remote, and the whole thing is a wired connection in black, with metal and plastic construction.
Who should buy it: DJs who cue one ear at a time, producers and editors who need isolation while tracking, and anyone who wants a wired, no-battery, full-size pair that plugs into both consumer and pro gear. Who should skip it: anyone who wants Bluetooth, anyone who mostly listens on the move and wants something feather-light, and anyone shopping for a child — this is an adult-oriented product with a 1-year manufacturer warranty, and the 0.6 kg weight is not a kids' accessory weight.
This is a back-to-school bundle, and the bundle is the point. You get four coordinated pieces: a 15-inch kids backpack, a foldable kids headphone, a matching insulated lunch bag, and a pencil case. The colorway is a purple flower design, and every piece matches, so you are not assembling a set from three different listings and hoping the purples agree. For a parent in late August, that single-box convenience is the actual feature.
The sizing is aimed squarely at young children. The backpack is a small harness with adjustable shoulder straps and a zipper closure, and the manufacturer describes it as designed for girls ages 5–8, with an age range of 3+ years. The dimensions given are 7.1 inches deep by 12.6 inches wide by 7.1 inches high, with a compatible device size of up to 15 inches — so a tablet or a small laptop-style sleeve fits, and a folder or a couple of books fits comfortably. Storage volume is listed at 25 liters, which for a primary-school child is a real backpack, not a toy.
Two spec details are worth flagging because they affect daily life. First, the material is polyester with a nylon lining and the water resistance level is listed as waterproof — useful for walks to school in drizzle and for the inevitable juice-box incident. Second, the care instruction is hand wash only, which tells you the shell is a soft, lightweight fabric rather than a structured, wipe-clean pack. If you want something you can throw in a washing machine, this is not it.
Who should buy it: parents, grandparents and gift-givers shopping for a girl in kindergarten, preschool or elementary school who wants a complete, matching set and a pack that fits a small frame. Who should skip it: older kids and teens, anyone who needs a large school pack for heavy textbook loads, and anyone shopping for audio gear — the included headphones are a foldable kids' accessory, and nothing in the specs suggests they are a substitute for a proper listening pair.
• Best for isolation and one-ear cueing → Hercules HDP DJ45. The closed-back circumaural design and pivoting earpieces exist specifically for this.
• Best for a complete, coordinated gift in one purchase → Similove Kids Backpack. Four matching pieces, one box, ages 5–8.
• Best for plugging into pro gear → Hercules HDP DJ45. It ships with both a 3.5 mm jack and a 6.35 mm adapter, so mixers and interfaces are covered.
• Best for a child's school day → Similove Kids Backpack. Waterproof polyester, adjustable shoulder harness, 25 liters, and an insulated lunch bag in the set.
• Best for travel and packing down small → Hercules HDP DJ45. Fold and turn the earpieces; the spiral cable shortens to about 3.3 feet.
• Best for a device up to 15 inches → Similove Kids Backpack. The compatible device size is listed at 15 inches, matching the pack's own 15-inch class.
• Best for long listening sessions without ear pressure → Hercules HDP DJ45. Circumaural padding around the ears and under the headband is the whole design intent.
• Best for low-maintenance cleaning → Hercules HDP DJ45. The kids' pack is hand wash only; the headphones just need a wipe.
In my opinion, the right pick depends entirely on who you are shopping for, and I would not pretend otherwise. If you are buying for yourself and you want a wired, isolating, DJ-ready over-ear pair with one-ear monitoring and both jack formats, I would buy the Hercules HDP DJ45 — the rotating earpieces and the 60-ohm drivers do a specific job well, and the design is honest about what it is. If you are buying for a 5–8 year old girl heading back to school, I would buy the Similove Kids Backpack — the four matching pieces and the waterproof polyester build solve a real problem in one purchase. Just check the current price on Amazon before you decide, since that is the one thing that can tip the balance either way.
Yes — that is exactly what it is built for. Closed-back circumaural cups for isolation, rotating earpieces for one-ear monitoring, a one-side spiral cable that extends past 6.6 feet, and both 3.5 mm and 6.35 mm connections for consumer and pro outputs.
Yes. The set includes four pieces: a 15-inch backpack, a foldable kids headphone, an insulated lunch bag, and a pencil case, all in a matching purple flower design. The headphones are a children's accessory, not a monitoring pair.
They are not in the same category. The HDP DJ45 uses 60-ohm dynamic drivers rated 20 Hz–20 kHz with passive sound isolation. The Similove headphones are a foldable kids' item with no audio specs listed, so a direct sound comparison is not meaningful.
Honestly, no — they serve different buyers. One is adult DJ gear; the other is a children's school bundle. They are only compared here because shoppers sometimes see "headphones" in both listings and wonder which one fits their need.
