• AILIHEN Kids Headphones — biggest strength: A volume-limited 93dB design with a foldable, adjustable, pillow-soft build clearly aimed at children aged 3 and up.
• AILIHEN Kids Headphones — biggest trade-off: It is wired only, with no noise control and no wireless option, so it lives and dies by the 3.5mm jack.
• ULTECHNOVO Retro Over Ear — biggest strength: A vintage-looking wired design marketed for studio, travel, photography and costume use, with an ergonomic fit and a lightweight build.
• ULTECHNOVO Retro Over Ear — biggest trade-off: It ships with no warranty and the data sheet describes it as an in-ear placement model, so the "over ear" naming and the actual fit description don't line up cleanly.
• Who AILIHEN is for: Parents buying for a young child who needs a safe, comfortable, school-ready headphone.
• Who ULTECHNOVO is for: Adults chasing a retro aesthetic for recording sessions, travel, photography or costumes.
The AILIHEN I35 is designed around one idea: protecting young ears. The headline spec is a volume limit of 93dB, which the brand frames as hearing protection for children. That single number tells you more about this headphone than any styling detail. If a child turns the volume all the way up, the output is capped rather than left entirely in their hands. For a parent, that is the whole point.
Comfort is the second pillar. AILIHEN uses memory-protein cushioned earmuffs and a pillow-soft headband, and the headband is adjustable to fit different head sizes. The build is lightweight, and the brand positions it for kids aged 3 and up. There is also an inline HD microphone on a braided cable with a single button for music and calls, so it works for classroom video calls and casual chatting, not just music.
Who should buy it: Parents of a child aged 3 or older who wants a durable, comfortable, foldable headphone for school, homework, travel and general listening — especially if the child uses a Chromebook or tablet with a headphone jack.
Who should skip it: Anyone who wants wireless freedom, active noise cancellation or a grown-up aesthetic. There is no noise control here and no Bluetooth. Adults looking for a personal listening headphone should look elsewhere.
ULTECHNOVO Retro Over Ear: Who It's For
The ULTECHNOVO Retro Over Ear is a very different animal. Its identity is style first. The black PVC-and-sponge build is pitched as a vintage, classic look, and the brand explicitly suggests it for studio recording, travel, photography and costumes. If you are building a retro look for a shoot, a stage costume or a themed setup, this is the kind of headphone that reads correctly on camera.
Functionally, it is plug-and-play. It uses a standard jack plug and a wired connection, so it hooks up to computers, phones and audio players without charging. ULTECHNOVO describes clear, detailed stereo reproduction of vocals and instruments, and an ergonomic design that reduces ear pressure so it can be worn for longer sessions at a desk or on a trip. The adjustable fit is meant to keep it secure during movement. It weighs just 27.22 grams, which is genuinely light.
Two things in the data sheet deserve a plain warning. First, the warranty description is "No Warranty," so you are buying this as-is. Second, the product details list the ear placement as "In Ear" and the folding feature as "In Ear," even though the title and description call it over-ear. That mismatch is worth knowing before you buy. It may be a listing inconsistency, but you should not assume a plush, full-size over-ear fit.
Who should buy it: Someone who values the vintage look for recording, photography, costume or travel use, wants a lightweight wired headphone with no charging hassle, and is comfortable buying without a warranty.
Who should skip it: Parents shopping for a child, anyone who needs a volume cap, and anyone who wants a guaranteed over-ear fit or noise isolation. There is no volume limiting and no noise control here.
• Best for young children → AILIHEN Kids Headphones. The 93dB volume limit is the deciding spec.
• Best for a retro or costume look → ULTECHNOVO Retro Over Ear. Its stated purpose is style, photography and recording.
• Best for school and Chromebook use → AILIHEN Kids Headphones. The 3.5mm wired connection and inline mic fit classroom and homework setups.
• Best for lightweight wear → ULTECHNOVO Retro Over Ear. At 27.22 grams, it is built to sit lightly.
• Best for comfort data → AILIHEN Kids Headphones. Memory-protein cushions and a pillow-soft, adjustable headband are spelled out.
• Best for travel and packing → AILIHEN Kids Headphones. It folds, which the ULTECHNOVO data sheet does not claim.
• Best for warranty peace of mind → AILIHEN Kids Headphones. ULTECHNOVO states no warranty.
• Best for plug-and-play with no charging → Either. Both are wired and neither needs a battery.
• Best fit certainty → AILIHEN Kids Headphones. Its on-ear design is described consistently, while ULTECHNOVO's fit description is contradictory.
In my opinion, the AILIHEN Kids Headphones are the safer, more coherent buy. The data sheet is consistent, the volume limit is a real safety feature, and the comfort and folding design line up with how families actually use headphones. I would pick ULTECHNOVO only if the retro look is the entire point — for a shoot, a costume or a themed desk setup — and I would accept the no-warranty and fit ambiguity as part of that choice. If you are buying for a child, AILIHEN is the one I recommend. If you are buying for a look, ULTECHNOVO earns its place.
FAQ
No. They are wired with a standard 3.5mm jack and an inline microphone on a braided cable. There is no Bluetooth and no battery to charge.
They are not marketed for children and the data sheet shows no volume limiting. For a child, I would steer toward the AILIHEN model instead.
The product details state no warranty. That is a real trade-off to weigh against the vintage styling.
Both data sheets omit pricing, so I cannot compare cost here. Check the current price on Amazon for each before deciding, since value depends on what each is going for at the time.
