If you want a volume-limited, foldable on-ear headphone built specifically for a child's school day, choose AILIHEN I35; if you need a five-pack of USB-C in-ear earbuds to hand out to a class, a team or a family, choose Bulktech 5.
These two look like they belong in the same shopping cart, but they solve completely different problems. One is a single pair of kid-focused headphones with a hearing-safety cap and a 3.5mm plug. The other is a bulk box of five USB-C earbuds meant to be distributed, replaced and forgotten. If you are torn, the deciding question is simple: are you buying for one young child, or are you equipping several people at once?
• AILIHEN I35 — biggest strength: A 93dB volume limit plus pillow-soft memory-protein ear cushions and an adjustable headband, all in a foldable on-ear frame for kids aged 3 and up.
• AILIHEN I35 — biggest trade-off: It is one pair, wired to 3.5mm only, so it will not connect to a USB-C-only phone or tablet without the right adapter.
• Bulktech 5 — biggest strength: Five individually wrapped USB-C in-ear earbuds with inline mics, so you can equip a whole group or keep spares everywhere.
• Bulktech 5 — biggest trade-off: No volume limiting, no on-ear cushioning, and a USB-C-only plug that will not fit older 3.5mm jacks.
• Buy the AILIHEN I35 if you are shopping for one child's classroom, Chromebook or tablet use and you care most about comfort and capped volume.
• Buy the Bulktech 5 if you need several pairs at once for students, staff, travel kits or backups and your devices are USB-C.
The AILIHEN I35 is a wired on-ear headphone with a very specific mission: keep a child's listening volume capped and keep the headset comfortable enough that they stop fidgeting with it. The 93dB limit is the headline feature here. That ceiling is the whole reason this product exists, and it is the thing that separates it from a generic pair of headphones you might hand a kid. If your child is on a Chromebook, tablet, laptop, MP3 player or computer with a standard 3.5mm jack, this is a straightforward plug-and-play fit.
Comfort is the second story. The headband is adjustable to fit different head sizes, and the memory-protein ear cushions and faux leather on-ear pads are designed to reduce the tiredness that builds up over a long school day or a flight. It is lightweight at 5.92 ounces, so it does not weigh a young child down. The frame folds up, which matters more than people expect — it slips into a backpack pocket instead of getting crushed loose in a bag.
The inline microphone on the braided cable is the practical classroom feature. There is a single button for play and call control, so a child can join a video lesson, answer a call or pause audio without reaching for the device. The control type is listed as touch and the noise control as sound isolation, so expect some passive blocking of background noise rather than active cancellation.
Who should skip it? Anyone buying for an adult, anyone who needs a USB-C-only connection with no adapter, and anyone who needs several pairs at once. It is also not the pick if you want in-ear tips or active noise cancellation. This is a single-purpose kids' headphone, and it is honest about that.
The Bulktech 5 is a different animal entirely. You are buying five pairs of black USB-C in-ear earbuds in one box, each individually wrapped. That packaging detail is the point: it makes the set easy to hand out, store, and keep hygienic when different people are using them. If you run a classroom, a small office, a training session or a conference, or you just want a spare pair in every bag and drawer, this is the format that makes sense.
The connection is USB-C, plug-and-play, no adapters and no Bluetooth pairing. That is a real convenience with modern Chromebooks, Android phones, tablets and laptops. The trade-off is equally real: if a device only has a 3.5mm jack, these will not fit it. Check what your devices actually have before you commit, because that single detail decides whether this set works for you at all.
In-ear silicone tips give a snug fit and passive noise isolation, which helps in a noisy room, on a call, or during a test where you want to shut out distractions. The inline mic and one-button controller handle calls, play/pause and voice assistant activation. The 4ft flat tangle-free cable is built for being stuffed into bags and pulled out again. Impedance is 32 ohm and the frequency range runs 20Hz to 20,000Hz, matching the AILIHEN on paper.
Who should skip it? Anyone buying for a young child who needs a capped volume ceiling, anyone who wants on-ear cushions instead of in-ear tips, and anyone whose devices are still on 3.5mm. There is also no volume limiting here, so a child using these has no built-in hearing protection. Age range is listed as kids and adults, but the safety feature that makes the AILIHEN a kids' product is simply absent.
• Best for young children → AILIHEN I35. The 93dB limit is the reason to pick it; the Bulktech 5 has no volume cap.
• Best for equipping a group → Bulktech 5. Five pairs, individually wrapped, ready to distribute.
• Best for comfort over long sessions → AILIHEN I35. Memory-protein cushions, an adjustable headband and a lightweight 5.92-ounce build designed for kids.
• Best for USB-C devices → Bulktech 5. Native USB-C, no adapters, no pairing.
• Best for 3.5mm devices → AILIHEN I35. Standard 3.5mm jack for Chromebooks, laptops, tablets and MP3 players.
• Best for travel and storage → AILIHEN I35. The folding design packs down; the Bulktech 5 relies on its flat tangle-free 4ft cable.
• Best for hygiene and sharing → Bulktech 5. Individually wrapped pairs are far easier to hand out and keep separate.
• Best for isolating noise → Bulktech 5. In-ear tips with passive noise isolation block more background than on-ear pads.
• Best for a single-headphone purchase → AILIHEN I35. One pair, one owner, one clear purpose.
If you want to know how the two compare on cost, check the current price on Amazon — the two products sit in very different buying categories, and the value math changes depending on whether you need one pair or five.
In my opinion, the right pick comes down to one question: how many people are you buying for? If it is one young child and you care about a capped 93dB volume and all-day comfort, I would buy the AILIHEN I35. The hearing-safety cap and the foldable, adjustable, cushion-heavy design are exactly what a school-age kid needs. If you are outfitting several people and your devices are USB-C, I would buy the Bulktech 5 instead — five individually wrapped pairs with mics is simply the more practical purchase for a group, even though it gives up volume limiting and on-ear comfort. For a single child, AILIHEN wins. For a group, Bulktech wins.
FAQ
For a young child, yes — in my opinion. The AILIHEN I35 has a 93dB volume limit and memory-protein on-ear cushions, while the Bulktech 5 has no volume cap and uses in-ear tips. If hearing safety is your priority, the AILIHEN is the more appropriate choice.
No. The Bulktech 5 uses a USB-C connector, so it fits USB-C phones, tablets, Chromebooks and laptops. If your device only has a 3.5mm jack, you need the AILIHEN I35 or the right adapter.
The Bulktech 5. Its in-ear silicone tips create a seal that passively blocks background noise. The AILIHEN I35 is an on-ear design listed with sound isolation, which blocks less than a proper in-ear seal.
Five, each individually wrapped. That is the main reason to choose it over the AILIHEN I35, which is a single pair of headphones. If you need spares or you are equipping a group, the five-pack is the more efficient buy.
Yes. It has an inline HD microphone on a braided cable with a single button for music and call control, and it connects over a standard 3.5mm jack, so it works with Chromebooks, laptops, tablets and phones that still have that port.
