If you want in-ear fit, personalized sound, and sweat resistance for children, choose Denon PerL Pro True; if you need long battery life and an over-ear design, choose Edifier ES850NB. The Denon is the more compact, feature-rich option, while the Edifier offers much longer stated playback between charges. Neither is listed as waterproof, so I would not choose either for swimming or water-heavy activities.
• Denon PerL Pro True: In-ear earbuds with customizable sound, adaptive noise cancellation, and IPX4 sweat and water resistance; trade-off: 8 hours of playback in Normal Mode, with more in Low Power Mode when using the case.
• Edifier ES850NB: Over-ear headphones with up to 92 hours of playback with ANC off; trade-off: its listed weight is 260 g, and it is not specified as water-resistant.
• Choose Denon for an in-ear fit, multiple ear-tip and wing options, customizable touch controls, and adaptive audio features.
• Choose Edifier for over-ear coverage, several noise-control modes, a foldable design, and extended playback.
• For children: Denon may suit someone who prefers earbuds and needs sweat resistance; Edifier may suit someone who wants an over-ear style and fewer charging interruptions.
The Denon PerL Pro True is an in-ear set built around customizable listening. Its Masimo Adaptive Acoustic Technology and the Denon Headphones app let users tailor the sound, while Dirac Virtuo adds spatial audio. Adaptive noise cancellation, Social Mode for hearing nearby sounds, and an Immersion Mode that adjusts bass give it several ways to shape listening.
It comes with five ear-tip options and two wing attachments, which offer more fitting combinations than a one-shape-only design. There are four customizable touch inputs on each earbud, and the stated Bluetooth range is 10 meters. For calls, the product information lists eight microphones, Qualcomm aptX Voice, and Multipoint for connecting two devices at once. Those features could be useful for a child who moves between a tablet and another device, though the listed age range is adult, so fit and suitability should be considered individually.

The Edifier ES850NB takes the opposite approach: it is an over-ear design with leather ear cushions, a steel headband, and a stated weight of 260 g. Its foldable construction is useful to consider for packing, while Touch-to-Chat and app and touch controls add ways to manage listening. It supports wired and wireless listening according to its product description, though the listed connectivity details specify wireless technology and no headphone jack. I would not assume a wired connection is available through a conventional jack.
Its standout spec is battery life: up to 92 hours with ANC off or 53 hours with ANC on. Edifier also states that a 15-minute fast charge can provide up to 11.5 hours of playback with ANC off. For long travel days or a child who often forgets to charge headphones, those figures make the Edifier compelling on paper. The sound options include Music, Game, and Spatial modes, and its 40 mm titanium-coated drivers support LDAC and SBC.
The trade-offs are different from Denon’s. The Edifier is not listed as water-resistant, so I would avoid treating it as suitable for sweaty workouts or wet play. Its over-ear build may appeal to a child who dislikes earbuds, but 260 g is a specific weight to keep in mind for extended wear. The listing describes it for adults, so check whether the fit works for the intended child rather than assuming the headband will suit every age.
• Best for a child who prefers earbuds → Denon PerL Pro True. Its in-ear shape, five tip options, and two wing attachments allow several fit combinations.
• Best for long playback between charges → Edifier ES850NB. It is listed for up to 92 hours with ANC off and 53 hours with ANC on; Denon states 8 hours in Normal Mode.
• Best for sweat resistance → Denon PerL Pro True. Its IPX4 rating covers sweat and water resistance, but neither product is described as waterproof.
• Best for over-ear coverage → Edifier ES850NB. The design uses leather ear cushions and a steel headband rather than earbuds that sit in the ear.
• Best for tailoring sound to your ears → Denon PerL Pro True. Its adaptive acoustic technology and companion app are specifically described as personalization features.
• Best for different noise-control situations → Edifier ES850NB. It offers high, medium, wind-reduction, and ambient-sound modes.
• Best for calls and two-device connection details → Denon PerL Pro True. The listed call features include eight microphones, aptX Voice, and Multipoint.
• Best for a foldable travel design → Edifier ES850NB. Its foldable build and long stated battery life make it the more travel-oriented option on paper.
The phrase “crystal clear calls kids headphones for children” points toward a real distinction: Denon lists specific call-related features, while the Edifier description also mentions clear calls but does not provide the same microphone count or voice-codec details. I would not treat that as proof of call performance; it only tells me Denon provides more detail about the call setup.
Likewise, neither product should be mistaken for waterproof gaming headphones for children. Denon lists IPX4 sweat and water resistance, and Edifier lists no water-resistance rating. Edifier does include a Game sound effect, but that does not make it waterproof. And if the search is for on ear headphones for children, these are not on-ear designs: Denon is in-ear, while Edifier is over-ear.
For the comfort decision, fit preference matters more than a label. A child who dislikes anything inside the ear may prefer the Edifier’s over-ear cushions. A child who finds a headband bulky may prefer the Denon’s earbuds, provided the tips and wings fit securely. Since both are described for adults, I would not assume either is sized specifically for children.
I would choose the Denon PerL Pro True for children if the child is comfortable with earbuds and sweat resistance, personalized sound, and call features are the priorities.
Its shorter Normal Mode playback is a real drawback, but its fit options and IPX4 rating make it the more versatile choice for everyday listening that may include active use.
I would choose the Edifier instead for a child who specifically wants over-ear headphones and needs longer battery life.
For children, my recommendation is Denon, with the important caveat that neither product is listed as waterproof or specifically designed for children.
Denon is the more suitable choice on paper for a child who prefers earbuds and may benefit from IPX4 sweat and water resistance. Edifier may fit better for a child who prefers over-ear headphones. Both are described for adults, so check fit and comfort for the intended child.
Which has longer battery life, Denon PerL Pro True or Edifier ES850NB?
Neither is listed as waterproof. Denon has an IPX4 sweat and water-resistance rating, which is not a swimming rating. The Edifier information does not specify a water-resistance rating.
Edifier offers a Game sound effect, while Denon lists spatial audio, eight microphones, aptX Voice, and Multipoint. Those features serve different needs; the listed details alone do not establish which will sound better in a particular game or call setup.
