If you want wireless TV listening with a drop-in charging dock, choose Avantree Loop Dock; if you need wired, over-ear-routed in-ear monitors, choose HIFI WALKER A20. For toddlers, though, neither is a purpose-built headband headphone: the Avantree is the more convenient wireless option, while the A20 requires a cable and a 3.5 mm jack.
For a child, I would start by checking fit, supervision, and device compatibility—not by assuming either design is made for toddlers. The main difference is simple: the Loop Dock is built around wireless listening and easy charging; the A20 is a wired in-ear option with a detachable cable and three included ear-tip sizes.
• Avantree Loop Dock’s strength: Bluetooth and Auracast support, three EQ presets including Voice Clear, and a charging dock. Trade-off: it needs a compatible Bluetooth audio source for direct TV connection; it will not connect directly to a TV that outputs audio only through HDMI ARC/eARC, Optical, or AUX.
• HIFI WALKER A20’s strength: a wired in-ear design with an over-ear cable route, detachable two-pin cable, and three silicone ear-tip sizes. Trade-off: it has no wireless connection and no microphone.
• For wireless TV listening and simpler charging: choose the Avantree Loop Dock, after checking the TV’s audio output.
• For a wired listening setup with a 3.5 mm jack: choose the HIFI WALKER A20, provided its in-ear fit suits the listener.
The Avantree Loop Dock is the more flexible choice if you want to listen wirelessly. It supports Bluetooth and Auracast, and its audio codec support includes LC3, aptX Adaptive, aptX HD, aptX, and SBC. For TV or everyday listening, the three EQ presets give you options, including a Voice Clear mode intended to make speech stand out. That could be useful for dialogue-heavy shows, but it does not change the need for a compatible source.

The charging dock is its most practical distinction from the A20. Rather than plugging a cable into the earbuds for each charge, you place the headphones into the dock. That may make the routine simpler in a shared living room where you want the set kept together and ready for another listening session.
There is an important TV limitation: the Loop Dock is designed for TVs and devices with built-in Bluetooth audio. If a TV outputs audio only through HDMI ARC/eARC, Optical, or AUX, the headphones will not connect directly. I would skip this model if your setup lacks Bluetooth audio and you do not intend to add a compatible transmitter. I would also avoid treating it as a toddler-specific headset: the product information describes an adult age range, not a toddler fit. It is an in-ear neckband design, not a headband headphone.
The HIFI WALKER A20 is a wired in-ear monitor. Its cable routes over the ears, and the set includes three pairs of silicone tips in small, medium, and large. The over-ear route is designed to help keep the earbuds in place and reduce cable pull during use. That makes it a more suitable candidate when you want a wired setup for a device with a 3.5 mm jack and do not need wireless freedom.
The cable is detachable, which gives the design a different kind of flexibility from the Loop Dock. You can remove the included two-pin cable, but the A20 remains a wired product; it does not offer Bluetooth or Auracast. The product is described for music, gaming, and studio use, but it has no microphone. So I would not choose it for calls or voice chat when a mic is required.
For toddlers, the A20’s small ear tips may sound like an easy fit advantage, but the listed tip sizes do not establish that the earbuds are designed or sized for young children. It is still an in-ear monitor with a cable. If you are searching for the best headband headphones for toddlers, neither pick matches that form factor. I would also skip the A20 if the listening device lacks a 3.5 mm jack or if you want a wireless setup.
• Best for wireless listening → Avantree Loop Dock. It supports Bluetooth and Auracast; the A20 is wired.
• Best for a drop-in charging routine → Avantree Loop Dock. Its charging dock avoids plugging a charging cable into the headphones.
• Best for a wired device with a 3.5 mm jack → HIFI WALKER A20. It connects through a standard 3.5 mm headphone jack.
• Best for choosing among ear-tip sizes → HIFI WALKER A20. Three silicone tip sizes are included, though that alone does not guarantee a toddler fit.
• Best for dialogue-focused EQ options → Avantree Loop Dock. It has three presets, including Voice Clear.
• Best for avoiding wireless setup → HIFI WALKER A20. Its wired connection needs no Bluetooth pairing.
• Best for a toddler-specific headband design → Neither. Both products are in-ear options, and neither is described as a toddler headband headset.
• Best for voice chat with a built-in mic → Neither is a clear choice. The A20 is specified as having no mic, and the Loop Dock’s listed MEMS voice mic is not a reason to assume it suits every call or gaming setup.
I would choose the Avantree Loop Dock for a household that wants wireless listening, Voice Clear EQ, and a dock that simplifies charging—provided the TV supports Bluetooth audio or you have a compatible transmitter.
For toddlers, my recommendation is more cautious: neither product is presented as toddler-specific, and neither is a headband design. If those are the main requirements, I would keep looking rather than assume an in-ear fit is appropriate. Between these two, I would still pick the Loop Dock for supervised, compatible wireless listening because it avoids a cable and has the more convenient charging setup.
Neither is described as made for toddlers. The Loop Dock’s product information gives an adult age range, while the A20 is an in-ear monitor with a cable. Check fit and suitability carefully before choosing either for a young child.
No. They are designed for TVs and devices with built-in Bluetooth audio. A TV that outputs audio only through HDMI ARC/eARC, Optical, or AUX will not connect directly to them.
No. The A20 is wired through a 3.5 mm jack, and its product description specifies no microphone. It is not a Bluetooth option for wireless listening or voice chat.
The A20 is described for gaming and connects by wire, but it has no mic. The Loop Dock offers Bluetooth and aptX Adaptive support for lower audio lag with compatible transmitters, but its usefulness depends on the source and setup. Neither is a clearly specified gaming headset for toddlers.
