• Avantree HF039 biggest strength: a 16.4 ft / 5 m coiled cord with an inline volume dial and a stereo/mono switch — designed for TV and PC listening at a distance, with no charging ever.
• Avantree HF039 biggest trade-off: it's wired, has no microphone, and needs an RCA or 6.35 mm adapter (sold separately) for older TVs and AV receivers.
• Candy Bila Kids Headphones biggest strength: a dual 85/94 dB volume limiter plus an inline remote with mic, wrapped in a tear-resistant nylon cord and a foldable frame.
• Candy Bila Kids Headphones biggest trade-off: it's built for children, not for long-distance TV listening, and it has no active noise control.
• Pick Avantree HF039 if you're an adult watching TV, gaming on a PC, or listening at a desk where a long cord and a volume dial matter more than portability.
• Pick Candy Bila Kids Headphones if you're buying for a child who needs safe volume limits, a mic for class calls, and a headphone that folds up into a backpack.
The HF039 is, at heart, a problem-solver for one specific annoyance: sitting down to watch TV and finding your headphone cable is too short, too stiff, or constantly tugging at your ears. Avantree's answer is a coiled cable rated at 16.4 ft / 5 m when fully stretched, and the brand notes that in normal use you get well over 10 ft / 3 m of effective slack between the device and your head. That coil isn't just length — it absorbs tension, so a sudden movement doesn't rip the pads off your ears.
Sound is handled by 40 mm dynamic drivers with a 20 Hz–20 kHz range, 32 ohm impedance and 101 dB sensitivity. In plain terms, that's an easy-to-drive spec that any phone, tablet, laptop or TV headphone jack can push without a separate amp. Avantree describes the tuning as natural, clear and deep in the bass rather than flat and analytical. Comfort gets real attention too: over-ear faux-leather pads, an adjustable headband, and a total weight of just 155 g / 5.5 oz, which is light enough for a full film or a long work session. There's also a collar clip so the cable stays put instead of swinging around.
The details that matter most are the practical ones. Volume lives on an inline dial, not on the device. A stereo/mono switch solves the classic one-ear-only problem on some TVs. And there's no battery, no pairing, no charging — plug in and listen.
Who should buy it: anyone who watches TV or uses a PC at a distance, wants zero battery management, and prefers a physical volume control they can find by touch. Who should skip it: anyone who needs a microphone (the HF039 has none), anyone who wants wireless freedom, and anyone with a TV that only outputs RCA or 6.35 mm — you'll need to buy a converter separately, and you'll need to switch your TV's audio output setting to "Headset" or "External Speakers" in the menu. The spec sheet also notes Bluetooth under connectivity, but the headphone jack is 3.5 mm wired — treat this as a wired product first and confirm your exact use case before buying.
The Candy Bila set is designed around a different user entirely: a child, and a parent who wants one less thing to worry about. The headline feature is a dual volume limiter at 85/94 dB, which caps how loud the headphones can get — the single most useful safety feature you can put in a kid's headphone. Instead of a bare cable, you get a one-button inline remote that handles play/pause, answer/hang up, and track skipping. There's a built-in microphone, which turns these into a workable headset for online classes, video calls and chatting at home.
Build quality is clearly aimed at abuse. The cable is tear-resistant nylon, specifically chosen because kids yank on cords. The frame folds, which matters more than it sounds — folded headphones fit in a school bag pocket instead of getting crushed at the bottom of a backpack. The finish is a matte gradient red, and the whole thing ships in a rigid, cushioned box, which makes it a plausible gift rather than a loose accessory. Candy Bila backs it with a 1-year warranty.
Audio specs are modest but sensible: dynamic drivers, 32 ohm impedance, 20 Hz–20 kHz, over-ear faux-leather pads. That impedance means it runs fine from a Kindle Fire tablet, phone, laptop or PC over a standard 3.5 mm jack — no adapter hunting. There's no noise cancellation, which is normal at this tier and arguably fine for kids, since you generally want a child to still hear a parent or a teacher.
Who should buy it: parents buying for school-age kids, families who need a mic for remote learning, and anyone who wants volume limiting as a hard guarantee rather than a hopeful setting. Who should skip it: adults who want a serious TV headphone, anyone listening in a loud environment who needs isolation, and anyone who wants a long coiled cable — the Candy Bila is a normal-length portable cord, not a room-spanning one.
• Best for long-distance TV and PC listening → Avantree HF039. The 16.4 ft / 5 m coiled cable and >10 ft effective slack are the whole point.
• Best for child safety → Candy Bila Kids Headphones. The 85/94 dB limiter is a hard cap, not a suggestion.
• Best for calls and online classes → Candy Bila Kids Headphones. It has a microphone and a one-button inline remote; the HF039 has no mic at all.
• Best for never charging anything → Avantree HF039. Fully wired, no battery, no pairing, no downtime.
• Best for travel and school bags → Candy Bila Kids Headphones. The foldable design and tear-resistant nylon cord are built for being stuffed into bags.
• Best for adjustable volume at your fingertips → Avantree HF039. The inline dial plus the stereo/mono switch gives you more control over the listening experience.
• Best for long sessions in one seat → Avantree HF039. Over-ear pads on a 155 g / 5.5 oz frame with a collar clip to keep the cable from dragging.
• Best for a gift that arrives presentable → Candy Bila Kids Headphones. Rigid cushioned packaging and a matte finish.
• Best all-rounder for a family with both needs → buy both. They solve genuinely different problems, and neither one substitutes for the other.
If I were choosing for myself, I'd buy the Avantree HF039. My reasoning is simple: the coiled 16.4 ft cable, the inline volume dial, the stereo/mono switch and the light 155 g over-ear build solve a real daily annoyance for TV and PC listening, and the wired design means I never think about charging. That said, I'd only recommend it to an adult with a 3.5 mm output and no need for a mic.
If the headphone is for a child, I'd buy the Candy Bila Kids Headphones instead — the 85/94 dB limiter, the mic and remote, and the tear-resistant foldable build are exactly what a kid's headphone should prioritize. In my opinion these two aren't competitors so much as different tools, and the right answer depends entirely on who's wearing them.
FAQ
Yes. There's a built-in mic plus a one-button inline remote for play/pause, answering and ending calls, and switching tracks, which is what makes them usable for online learning.
If your TV has a 3.5 mm audio output, yes. If it only has RCA or 6.35 mm outputs, you'll need an RCA-to-3.5 mm or 6.35 mm-to-3.5 mm converter, sold separately, and you'll need to set the TV's audio output to "Headset" or "External Speakers."
For a child, the Candy Bila is the safer and more practical pick because of the volume limiter, mic and durable foldable build. For an adult who wants TV audio at a distance with no battery to manage, the Avantree HF039 is the better fit.
