How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a protective, travel-ready home for a pair of foldable on-ear headphones, choose DigiCharge Carry Case; if you need a classroom-ready set of eight wired on-ear headphones for kids, choose Hengliyuan Kids Headphones Bulk.
These two products barely compete for the same buyer — one is a storage shell, the other is a stack of budget headphones — but shoppers searching them side by side are usually trying to solve one of two problems: protecting a headset they already own, or equipping a room full of students without spending a fortune. This comparison breaks down what each one actually does, where it falls short, and which one fits your situation.
• DigiCharge Carry Case — biggest strength: A hard EVA shell with a 900D nylon exterior, water-resistant finish, soft flocking lining and honeycomb air cushion built specifically around flat-folding on-ear headphones.
• DigiCharge Carry Case — biggest trade-off: It is storage only. You still need to own compatible folding headphones, and it will not fit headphones that do not fold flat.
• Hengliyuan Kids Headphones Bulk — biggest strength: Eight individually wrapped wired on-ear headphones in eight colors, with retractable headbands, swivel earcups and reinforced 3.5mm plugs.
• Hengliyuan Kids Headphones Bulk — biggest trade-off: Wired, plastic-bodied, and clearly built as a classroom consumable rather than a hi-fi listening device.
• Who each pick is for: DigiCharge is for one careful adult protecting one good pair of folding headphones. Hengliyuan is for teachers, schools and parents buying for a group.
The DigiCharge Carry Case is a single-purpose object, and that is exactly its appeal. Its job is to keep a pair of flat-folding on-ear headphones safe when they leave your desk. The construction tells you how seriously it takes that job: a strong EVA foam shell to absorb knocks and drops, a 900D nylon exterior with a black diamond pattern that resists splashes and impacts, and an interior lined with soft flocking plus a honeycomb air cushion to stop scratches from the inside out.
The design leans on your headphones' own folding feature. Because the case is built around flat-folding models, it stays compact — the listed dimensions are 8.27 x 7.87 x 2.95 inches — and a comfortable handle plus a heavy-duty zip make it a realistic thing to throw in a backpack or carry-on. There is also a mesh pocket and a moulded insert for cables, chargers and small accessories, so your charging cable does not end up loose in a bag.
Compatibility is the part to check carefully before buying. DigiCharge lists it as fitting Sony WH-CH520, WH-CH510, MDR-ZX110, MDR-ZX310 and related models, plus JBL Live 680NC, Tune 520BT, Tune 510BT, Tune 660NC, Tune 560BT and others, along with a wider list that includes JBL JR 310, JBL T450BT, JBL Tune 500, JBL Tune 670NC, Sony MDR-XB550AP, MDR-ZX110NA and MDR-ZX310AP.
Hengliyuan Kids Headphones Bulk: Who It's For
Hengliyuan's bulk pack attacks a completely different problem: getting a usable set of headphones into the hands of eight people at once. You get eight wired on-ear headphones in red, orange, yellow, light blue, dark blue, pink, white and black, each individually wrapped and sealed — which matters if you are handing them out to students, storing them between classes, or giving them as small gifts. The color spread also makes it easy to assign one color per child and cut down on mix-ups.
The build is aimed at rough, everyday classroom use rather than critical listening. The cables are sturdy PVC and measure 1.2 m (about 47.25 inches), which gives kids real room to move without yanking the plug out. That 3.5mm plug uses a reinforced process that Hengliyuan says extends the cable's usable life by at least 6 to 12 months. The headband is retractable, so the same pair fits a child and an adult, and the earcups swivel to make storage easy. Soft sponge cushions and a lightweight plastic housing round out the comfort story.
On paper the audio side is modest but honest: 32 ohm impedance, 92 dB sensitivity and a 20.4 KHz frequency response, with sound isolation rather than active noise cancelling, and a wired 3.5mm connection to iPads, tablets, smartphones and PCs. There is no microphone or Bluetooth listed, so treat these as straightforward plug-in headphones.
Buy it if you are a teacher, school buyer or parent who needs eight functional, kid-friendly headphones in one go, with a retractable fit that works across ages and a one-year warranty. Skip it if you want wireless listening, premium sound quality, or a single pair for an adult who cares about audio fidelity.
Side-by-Side: Which Should You Choose?
• Best for protecting headphones you already own → DigiCharge Carry Case. The EVA shell, nylon exterior and flocking interior exist for one purpose.
• Best for equipping a whole classroom → Hengliyuan Kids Headphones Bulk. Eight sealed headphones in eight colors is a set, not a single item.
• Best for young children → Hengliyuan Kids Headphones Bulk. Retractable headbands, swivel earcups, sponge cushions and a reinforced 3.5mm plug suit smaller, rougher users.
• Best for cable and accessory organization → DigiCharge Carry Case. The mesh pocket and moulded insert keep cables and chargers from rattling loose.
• Best for shared or multi-user settings → Hengliyuan Kids Headphones Bulk. Individually wrapped units and eight distinct colors fit rotation between students.
• Best for water and impact resistance → DigiCharge Carry Case. The case is explicitly water-resistant with a shockproof, scratch-resistant interior.
• Best if you need headphones, not a case → Hengliyuan Kids Headphones Bulk. DigiCharge does not produce sound at all.
In my opinion, the right pick comes down to whether you already own the headphones. If you have a pair of flat-folding on-ear headphones — a Sony WH-CH520, WH-CH510, MDR-ZX110 or a JBL Tune or Live model on the compatibility list — I would buy the DigiCharge Carry Case. It protects an investment you have already made, and the EVA shell, water-resistant nylon and soft lining are exactly the features that keep a headset alive through daily commuting and travel. I would only choose the Hengliyuan Kids Headphones Bulk if my goal were outfitting a group: eight wired, adjustable on-ear pairs, each sealed and color-coded, with a reinforced plug designed for heavy classroom handling. Different jobs, different answers — and if you are torn purely on cost, check the current price on Amazon before deciding, since the value math changes completely between a single protective case and an eight-pack.
are on ear headphones good
On-ear headphones rest against the ear rather than around it, which makes them lighter and easier to fold flat — that is precisely why DigiCharge builds its case around folding on-ear models like the Sony WH-CH520 and JBL Tune series. The trade-off is less sound isolation than over-ear designs. For travel, school and everyday listening they are a practical, portable choice.
which are the best over the ear headphones
That depends on your priorities, and neither product here is an over-ear model. DigiCharge makes a carry case for on-ear and flat-folding headphones, and Hengliyuan's bulk pack is explicitly on-ear with circular earcups. If you specifically want over-ear headphones, you would be shopping a different category — these two solve storage and classroom supply problems instead.
what are the best over the ear headphones to buy
I would not point you to either product for that, because both are on-ear rather than over-ear. What I can say is that if you already own flat-folding on-ear headphones, the DigiCharge Carry Case is the better companion buy, while Hengliyuan's eight-pack suits classrooms and families. Match the accessory to the headphones you actually have.
are these headphones wireless or wired
The Hengliyuan Kids Headphones Bulk is wired only, using a 3.5mm jack with a reinforced plug and a 1.2 m PVC cable — there is no Bluetooth listed. The DigiCharge Carry Case is not a headphone at all; it is a storage case, though it does include a mesh pocket for cables and small accessories.
