How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight neckband-style earbud set built for long listening sessions and near-zero TV audio lag with the right Avantree transmitter, choose Avantree Neckband Headphones Earbuds; if you need a volume-limited, light-up pair of over-ear headphones for a child, choose Candy Bila Kids.
• Avantree Neckband Headphones Earbuds — biggest strength: a 28 g (24 g listed in the item details) Flex-Form neckband with magnetic earbuds, inline volume remote, and up to 20 hours of playtime, plus low-latency TV pairing when used with compatible Avantree transmitters.
• Avantree Neckband Headphones Earbuds — biggest trade-off: it's adult-oriented in-ear gear, and the no-delay TV trick only works with specific Avantree transmitters (older HT4186/HT41866, Audikast series excluding Audikast 3, and Oasis/Oasis Plus) — the newer "-Q" transmitters need the separate NB16-Q model.
• Candy Bila Kids — biggest strength: a genuine kid-first design — 85/94 dB volume limiting, pulsing red/blue/green LEDs, soft protein earcups on a foldable padded headband, and a 3.5 mm wired mode plus TF card mode as backups.
• Candy Bila Kids — biggest trade-off: it's on-ear/over-ear rather than in-ear, so it's bulkier than a neckband, and it's aimed at children rather than adults who want a discreet personal audio setup.
• Who each pick is for: pick the Avantree for yourself — workouts, TV watching, calls, travel. Pick the Candy Bila for a kid or young teen who needs safe volume and a bit of fun.
The NB16 is a neckband headphone in the classic sense: a lightweight band that rests around your neck with two earbuds on a flex-form cable. The magnets hold the buds together when you're not using them, which keeps the wire from swinging around or tangling — a small detail that matters a lot during commutes or when you're moving between tasks. There's an inline remote for volume and calls, so you're not digging for your phone.
The headline number is battery life. Avantree rates it at up to 20 hours of continuous talk or music, with a 2-hour charge time. For most people that's several days of normal use between charges, and for a long-haul flight or a full workday it's more than enough. Sound is handled by a dynamic driver with a 20 Hz–20,000 Hz range and 32-ohm impedance, and the chipset is described as delivering hi-fi music plus clear voice for calls. Bluetooth 4.1 with a 10-meter range covers the usual phone-in-pocket, laptop-on-desk scenario. Fit is adjustable through a selection of earbud tips and wingtips, and the band is designed to be light enough that you forget it's there — the spec sheet puts it around 28 g, with the item details listing 24 g.
The feature that separates the NB16 from generic neckbands is the TV angle. Paired with compatible Avantree transmitters, it's built to virtually eliminate audio delay, and it can act as a second headphone in an HT4186 setup so two people can stream the same TV audio without lag. That's a real, specific use case: one person on the couch with a transmitter-equipped TV, two sets of earbuds, no lip-sync mismatch.
Who should buy it: adults who want a wearable, tangle-resistant earbud set for the gym, travel, calls, and especially TV watching through an Avantree transmitter they already own or plan to buy. Who should skip it: anyone shopping for a young child, anyone who wants over-ear cups instead of in-ear tips, and anyone with a newer "-Q" Avantree transmitter, since that combination needs the NB16-Q model instead.
This is a different product category entirely, and it's designed around a different user. The Candy Bila BH01 is an on-ear/over-ear headphone with soft protein earcups, adjustable metal sliders, and a padded, feather-light headband that folds for storage. The volume limiting is the core safety feature: it caps output at 85/94 dB, and the brand's pitch is that kids can still get clear vocals and full dynamic bass within that ceiling. For a parent, that's the reason to buy this over any adult headphone.
There's a lot of kid-appeal built in. Red, blue, and green LEDs at both ends pulse to the music, which is exactly the kind of thing that makes a child actually want to wear their headphones. Bluetooth is listed at 5.0 in the style field (the title says 6.0) with a 10-meter range — the title also cites 33 ft, which matches that 10 meters — and there's an HD noise-reduction mic for calls and online classes. The battery is rated at up to 25 hours with a 2-hour charge, though the title's "85 hours" figure likely refers to total playtime with the charging case or across multiple charges, so treat the 25-hour number as the realistic single-charge figure.
What I like most here is the redundancy. If the battery dies or Bluetooth misbehaves, there's a 3.5 mm wired jack and a TF card mode. That means the headphones don't become useless on a car trip or during a lesson. The controls are touch-based with media control, and the enclosure mixes protein leather-like material, metal, rubber, and foam — a build that reads as kid-durable rather than premium-audio. Warranty is listed at one year.
Who should buy it: parents of kids and young teens who want volume-limited, comfortable, fun-looking headphones for school, travel, and tablet time. Who should skip it: adults who want a discreet in-ear solution or low-latency TV audio, and anyone who needs a wired-only or in-ear form factor.
• Best for battery life → Candy Bila Kids on paper (25 hours rated versus Avantree's 20), though the Avantree's 20 hours is for a much smaller, lighter device.
• Best for TV and movie watching → Avantree Neckband Headphones Earbuds, because of the low-delay pairing with compatible Avantree transmitters and the dual-headphone HT4186 use case.
• Best for kids → Candy Bila Kids, thanks to the 85/94 dB volume limit, LED lights, and foldable over-ear comfort.
• Best for workouts and portability → Avantree Neckband Headphones Earbuds, with its 28 g neckband, magnetic buds, and tangle-free cable.
• Best for calls → a toss-up. Avantree has an inline remote and a chipset tuned for voice clarity; Candy Bila has an HD noise-reduction mic for clear communication. Pick based on who's wearing it.
• Best for backup play modes → Candy Bila Kids, which adds a 3.5 mm wired jack and TF card mode on top of Bluetooth.
• Best for a shared household → Avantree Neckband Headphones Earbuds. One adult set for TV and gym, and if you're buying for a child you'd add the Candy Bila alongside it rather than replacing it.
• Best for a child who breaks things → Candy Bila Kids, given the metal sliders, padded headband, and foldable design aimed at durability.
If I were buying for myself, I'd take the Avantree Neckband Headphones Earbuds. In my opinion, the combination of a 28 g neckband, magnetic earbuds, an inline remote, 20 hours of playtime, and genuine low-latency TV pairing with Avantree transmitters makes it the more versatile tool for an adult. It does the gym, the commute, calls, and movie night without asking you to swap gear.
That said, this isn't a "better product" call so much as a "different user" call. If the person wearing these is a child, I'd buy the Candy Bila Kids without hesitation — the volume limiting alone justifies it, and the LED lights, over-ear comfort, and wired/TF backup modes make it far more practical for a kid's daily routine. Check the current price on Amazon for whichever one matches your household.
The Avantree, clearly. It's designed to work with compatible Avantree transmitters to nearly eliminate audio delay, and it can pair as a second headphone in an HT4186 setup. The Candy Bila has no low-latency TV feature listed.
You can, but it's built for kids — the 85/94 dB volume limit will feel quiet to an adult, and the on-ear design is sized around a child's head. If you want headphones for yourself, the Avantree is the better fit.
Candy Bila is rated at up to 25 hours and Avantree at up to 20 hours, both with a 2-hour charge. The gap is small, and the Avantree is a much lighter device, so battery life shouldn't be the deciding factor.
Not any TV. It connects directly to Bluetooth-enabled smart TVs. For older TVs with optical or AUX ports, you need a compatible Avantree transmitter — older HT4186/HT41866, Audikast series (excluding Audikast 3), or Oasis/Oasis Plus. Newer "-Q" transmitters require the NB16-Q instead.
