If you want a wired, closed-back headphone with 53 mm drivers and a long cable for a stationary listening setup, choose Audio Technica ATH-A990Z; if you need a closed-back headphone built around portability, lightweight construction, and 40 mm aluminum/magnesium drivers, choose Focal AZURYS High-Fidelity Closed-Back. For toddlers, neither is described as a child-specific or open-ear design, so I would not choose either on the assumption that it offers those features.
• Audio Technica ATH-A990Z: Large 53 mm drivers, aluminum housings, and a system designed for deep bass; the 3.0 m wired cable is a practical drawback when moving around.
• Focal AZURYS High-Fidelity Closed-Back: Lightweight magnesium yoke, memory foam earpads, and a portable-focused design; it has smaller 40 mm drivers and a shorter listed frequency range.
• Choose Audio Technica for a more stationary setup and a long reach to your listening device.
• Choose Focal if you want a closed-back headphone described for listening at home or on the move.
• For toddlers, neither is specified as child-sized, open-ear, wireless, or sweat-resistant.
The ATH-A990Z is a wired, over-ear closed-back headphone built around 53 mm dynamic drivers. Its aluminum housings are intended to reduce unwanted resonance, while Audio-Technica’s Double Air Damping System is designed to support deep bass reproduction. The stated frequency response is 5 Hz to 45,000 Hz. Those are useful specifications for a listener who wants a full-size headphone geared toward detailed music playback and substantial low-frequency response.
Its 3.0 m cloth-wrapped cable suits a desk, home stereo, or another setup where you want room to move without sitting right beside the source. The package also includes a 6.3 mm stereo adapter. The trade-off is plain: a long wired cable is less convenient for walking around, and this is not presented as a wireless or child-specific model. The soft earpads and 3D wing support are intended to make extended listening comfortable, but the adult-oriented over-ear design may not suit every wearer.

I’d consider it for an adult who listens mostly in one place and values the combination of large drivers, closed-back construction, and a long cable. I’d skip it if portability is the priority, or if you are specifically looking for open ear headphones for toddlers. The product details do not identify it as open-ear or designed for children.
Focal’s AZURYS is also a wired, closed-back headphone, but its design is presented with listening on the move in mind. It uses 40 mm aluminum/magnesium “M”-shaped dome speakers, with a listed frequency response of 15 Hz to 22 kHz. The magnesium yoke is described as lightweight and balanced, while the headband combines genuine leather and braided textile with memory foam earpads. That package points toward someone who wants a more portable full-size listening option without giving up a cushioned fit.
The AZURYS also has a 3.5 mm jack and is described as a passive headphone. Its materials and build details are a distinctive part of the proposition: the blue finish draws inspiration from azurite, and the headphone is handcrafted in France. The available information does not specify a cable length, so I wouldn’t assume it offers the same reach as the ATH-A990Z’s 3.0 m cable.
I’d look at the Focal if you want a closed-back headphone for home and travel, and if its lightweight design and memory foam pads matter more to you than a long cable. I would not choose it as a substitute for sweat resistant earphones for toddlers: it is described as a wired, over-ear headphone, not a sweat-resistant or child-focused earphone.
• Best for a long cable reach → Audio Technica ATH-A990Z. Its cloth-wrapped cable measures 3.0 m, which is useful when your listening setup is not right beside your chair.
• Best for a portable-oriented design → Focal AZURYS. Focal describes its magnesium-yoke construction as lightweight and suited to listening at home or on the move.
• Best fit for a deep-bass priority → Audio Technica ATH-A990Z. Its Double Air Damping System is specifically described as supporting deep bass reproduction.
• Best fit for 40 mm aluminum/magnesium drivers → Focal AZURYS. Its “M”-shaped dome speakers are built from that material combination.
• Best for a specified 6.3 mm adapter → Audio Technica ATH-A990Z. That adapter is included alongside the headphone’s 3.0 m cable.
• Best for memory foam earpads and a genuine-leather headband → Focal AZURYS. Those materials are part of its comfort-focused construction.
• Best match for toddlers → Neither, based on the stated features. Neither is described as open-ear, child-sized, or sweat-resistant, and both are wired closed-back designs.
The driver size alone does not determine which headphone will sound better to you. The Audio Technica’s larger drivers and bass-focused design may appeal if you want a substantial low end, while Focal emphasizes precise, clear sound from its aluminum/magnesium drivers. Those are different design priorities, not a guaranteed winner for every listener.
For long listening sessions, both give you comfort-related features, but they approach them differently. Audio Technica cites soft earpads and a 3D wing support system. Focal lists memory foam earpads, a genuine-leather headband, and breathable braided textile. Those details help distinguish the designs, though they don’t establish how either will fit a particular person.
My Verdict
I’d choose the Focal AZURYS for an adult who wants a closed-back headphone with a lightweight, portable-minded design and memory foam earpads. The Audio Technica ATH-A990Z makes more sense for a stationary setup where its 3.0 m cable and deep-bass-oriented design are useful.
For toddlers, I would buy neither based on these specifications: neither is described as open-ear, child-sized, or sweat-resistant. If you are looking for open ear headphones for toddlers, these two closed-back models do not match that brief.
The ATH-A990Z is the clearer match if deep bass is your main priority: its design includes a Double Air Damping System described as supporting deep bass reproduction. That does not, by itself, establish which headphone will sound better to every listener.
No. Both are described as closed-back, wired, over-ear headphones, and neither is identified as a child-specific or open-ear model. The available product details do not establish suitability for toddlers.
Focal positions the AZURYS for listening at home or on the move and describes its magnesium yoke as lightweight. The ATH-A990Z has a 3.0 m cable, which is useful in a stationary setup but may be less convenient while walking around.
Neither product is described as sweat-resistant, and both are over-ear headphones rather than earphones. I would not treat either one as a sweat-resistant option for a toddler based on the listed features.
