How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a tiny, hidden in-ear earpiece that can plug into almost anything through an adapter and works well for computer calls and discreet listening, choose VKBAND 108B; if you need a kid-friendly, over-ear Bluetooth headphone with long battery life, volume limits and an AUX cord for a computer or tablet, choose seenda JCH-01.
• VKBAND 108B biggest strength: a 5x7x10mm in-ear earpiece weighing 0.8g that stays hidden in the ear canal while delivering calls, music and radio through a wired inductive loop with 3.5mm, Lightning and Type-C support.
• VKBAND 108B biggest trade-off: the earpiece runs on replaceable SR416SW/337 button batteries rated for 6–8 hours, and it needs an Apple-certified adapter to work reliably with iPhones.
• seenda JCH-01 biggest strength: Bluetooth 6.0, up to 75 hours of playtime, active noise cancellation, a 3.5mm AUX cord and 85/94dB volume limiting — a lot of kid-focused features in one over-ear package.
• seenda JCH-01 biggest trade-off: it's built for kids, weighs 250g, and its volume limit and playful Blue&Yellow design make it a poor fit for adults who want discreet or critical listening.
• Who each pick is for: VKBAND 108B for adults who need a covert earpiece that can connect to just about any device; seenda JCH-01 for parents buying a durable, long-lasting headphone for a child's school, travel and tablet use.
The VKBAND 108B is not a conventional headphone, and that's the whole point. The earpiece itself measures just 5x7x10mm and weighs 0.8g, so it disappears into the ear canal. Instead of streaming audio over Bluetooth, it picks up sound through an inductive loop you wear around your neck, hidden under a collar. That loop connects to your device with a 3.5mm plug, and VKBAND includes both a Lightning and a Type-C adapter so the same earpiece can serve an iPhone, an Android phone, a tablet or a handheld device.
For computer use, the appeal is the flexibility. Any laptop or desktop with a 3.5mm jack can drive it directly, and machines that only offer Type-C can use the bundled adapter. Because the receiver is analogue and magnetic, there's no pairing, no app, no dropouts — you plug in, tuck the loop under your shirt, and listen. It handles phone calls, music and radio reception, with a balanced armature driver covering 20 Hz to 20,000 Hz and a maximum volume of 110dB. Battery life comes from a non-rechargeable 337/SR416SW cell rated at 6–8 hours, and VKBAND ships two of them, so you can swap and keep going.
seenda JCH-01: Who It's For
The seenda JCH-01 is the opposite philosophy: visible, comfortable, and built around kids. It's an over-ear design in Blue&Yellow ABS plastic, weighs 250g, and uses a dynamic driver. Connectivity is Bluetooth 6.0, with a 3.5mm AUX cord in the box as a fallback for devices that don't do wireless — which is exactly what makes it useful for a school laptop or a desktop computer that only has a headphone jack.
The headline numbers are strong for this category. Battery life is rated at 75 hours, with a 1.5-hour charge time, so a child can get through a week of school and travel without a charger. There are three light modes, stickers and doodle-friendly fun in the box, and active noise cancellation. Volume is capped at 85/94dB, which is the feature parents actually care about: a hard ceiling on how loud the headphones can go.
For computer use, the AUX cord matters more than the Bluetooth. A kid doing homework on a laptop or joining a class call can plug in directly, and the built-in microphone handles voice. The padded fit is designed for smaller heads, and the over-ear shape spreads pressure rather than pressing into the ear canal.
Who should skip it? Adults. The volume limit, the bright colour scheme and the kid-oriented styling all point to a young user. If you want serious audio quality, deep bass or a grown-up look, this isn't it. But as a first proper headphone for a child — school, travel, iPad, long car rides — the combination of 75-hour battery, ANC, a wired backup and volume limiting is a sensible package, backed by a 1-year manufacturer warranty.
• Best for discreet, hidden listening → VKBAND 108B. The 0.8g earpiece sits inside the ear canal and the loop hides under clothing.
• Best for kids → seenda JCH-01. Volume limited to 85/94dB, padded over-ear fit, playful design, 1-year warranty.
• Best for battery life → seenda JCH-01. 75 hours per charge versus a 6–8 hour replaceable button cell.
• Best for connecting to old and new ports → VKBAND 108B. 3.5mm, Lightning and Type-C all covered out of the box via adapters.
• Best for computer calls with a microphone → both, but differently. VKBAND 108B for a private, invisible call on a laptop; seenda JCH-01 for a child on a class call with the AUX cord or Bluetooth.
• Best for noise control → seenda JCH-01. It has active noise cancellation; the VKBAND 108B has none.
• Best for true wireless freedom → seenda JCH-01. Bluetooth 6.0 with no cable to your device; VKBAND 108B always needs the loop connected.
• Best for adults who want a normal headphone experience → neither, honestly. VKBAND is covert by design, and seenda is built for children.
If I were buying for myself and my priority was a single earpiece that works with every device I own — including a computer — I would choose the VKBAND 108B. The adapter set, the analogue connection and the fact that it never needs pairing make it the more universal tool, and the hidden form factor is something no ordinary headphone can match. If I were buying for a child, I would choose the seenda JCH-01 without hesitation: 75 hours of battery, volume limiting and an AUX cord for a computer make it the safer, more practical gift. In my opinion, the deciding question isn't which is better — it's who's wearing it. For covert, all-device listening, go VKBAND. For a kid's daily driver, go seenda.
how to disconnect headphones from all devices
On the seenda JCH-01, you manage this the normal Bluetooth way: turn Bluetooth off on each device, or remove the JCH-01 from that device's paired list, and it will stop reconnecting. The VKBAND 108B doesn't pair at all — it connects physically through the loop and 3.5mm, Lightning or Type-C adapter, so "disconnecting" just means unplugging the loop from your device.
how to make headphones forget all devices
For the seenda JCH-01, open the Bluetooth settings on each phone, tablet or computer, find the JCH-01 entry and choose "forget" or "unpair" — repeat on every device you've connected it to. The VKBAND 108B has no stored pairings, because it uses an analogue inductive loop rather than Bluetooth, so there's nothing to forget.
how to unpair headphones from all devices
Unpairing is the same process as forgetting: go into each device's Bluetooth menu and delete the seenda JCH-01 from the saved list. If you only want to switch devices temporarily, just turn Bluetooth off on the one you're leaving. With the VKBAND 108B, unpairing isn't a concept — you simply move the loop's 3.5mm plug, or its Lightning/Type-C adapter, to the device you want to use.
how to listen to two devices at once with headphones
Neither of these two products is designed for simultaneous multi-device audio. The seenda JCH-01 connects over Bluetooth 6.0 to one source at a time, though you can switch sources by unplugging the AUX cord or reconnecting Bluetooth. The VKBAND 108B is analogue and wired through its loop, so it plays whatever single device the loop is plugged into. If you need true dual-device listening, you'd need a headphone with that specific feature — it isn't part of either spec sheet here.
