How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want compact in-ear earbuds with a big 13mm driver, Bluetooth 5.4, ENC call clarity and a 10-minute quick charge that buys you real listening time, choose HARMONY TWENTY-TWO HTT-9; if you need a volume-limited, drop-resistant pair of over-ear kids' headphones with marathon battery life and a wired fallback, choose iClever BTH22.
• HARMONY TWENTY-TWO HTT-9 — biggest strength: A 13mm dynamic driver paired with Bluetooth 5.4 and 45 ms latency, plus ENC on a four-mic array for calls. It is built for people who take a lot of voice calls on the move.
• HARMONY TWENTY-TWO HTT-9 — biggest trade-off: These are in-ear buds with 6 hours per charge and 40 hours total in the case. There is no wired audio option, and the ENC is for your voice on calls, not for muting the world you hear.
• iClever BTH22 — biggest strength: Volume-limited listening at 85 dBA (or 74 dBA for toddlers), a 60-hour battery, and a 3.5 mm cable that keeps the music going when the battery runs out.
• iClever BTH22 — biggest trade-off: It is an over-ear kids' headphone with passive noise isolation only and push-button controls. No app, no active noise cancellation, no adult-tuned sound signature.
• Who each is for: Pick the HTT-9 if you want everyday earbuds for music, gaming and hands-free calls. Pick the BTH22 if you are buying for a child aged 2+ and want hearing protection plus durability above everything else.
The HTT-9 is a classic true-wireless earbud, and the spec sheet tells you exactly where its priorities sit. The 13mm dynamic driver is large for an in-ear bud, which usually translates into more low-end presence than you get from the small drivers common at this size. Impedance is 32 ohm and sensitivity is 98 dB across a 20 Hz–20 kHz range, so it should be easy to drive from a phone without pushing the volume. Bluetooth 5.4 with a 10-metre range and 45 ms latency is the interesting part: that latency figure matters if you game or watch video, because it is the kind of number that keeps lip-sync tight.
Battery is where you need to read carefully. Harmony lists 6 hours of continuous play per charge and up to 40 hours total with the case, and the case itself carries a 400 mAh cell that recharges in about 1.5 hours. The quick-charge claim is the standout: 10 minutes in the case gives you roughly 100 minutes of playback. If you are the kind of person who remembers to charge things five minutes before leaving the house, that single feature is worth more than a bigger total number.
Then there is ENC. Harmony is explicit about what it is and is not — ENC cleans up the sound your microphones pick up so the person on the other end hears your voice and not the café, the street or the train carriage. It does not reduce what you hear while listening. That is an honest, useful distinction, and it tells you this bud was designed around calls: four mics, voice assistant activation by touch or hands-free with Siri or Google Assistant, IPX5 for sweat and light rain, and touch controls on the bud itself.
In my opinion, this is the pick for a commuter, a remote worker who lives on calls, or a casual gamer who wants low latency without a headset. Skip it if you want active noise cancellation for your own ears, if you refuse to charge a case, or if you need a wired fallback on a long flight. There is no 3.5 mm jack here — it is wireless or nothing.
The BTH22 is a different animal entirely, and it is not pretending otherwise. This is an over-ear kids' headphone with a hearing-safety mandate at its core. iClever's Sound Refiner caps output below 85 dBA, and it specifically attenuates the 2 kHz–4 kHz band — the range most associated with hearing damage at high volume. Hold the "+" and "–" buttons together and you drop into a 74 dBA mode aimed at toddlers. If you have ever winced watching a four-year-old crank the volume on a tablet, that button combination is the entire reason to buy this pair.
Battery is the headline number: 60 hours. Used four hours a day, that is roughly half a month between charges, and the charge itself takes about 1.5 hours over USB-C. More importantly, when it does run flat, you plug in the included 3.5 mm cable and keep going. On a long flight or a road trip, that wired fallback removes the single most common reason kids' headphones stop working mid-journey. Note the trade-off: the wired mode exists, the battery anxiety does not.
Build and fit are the other half of the story. The BTH22 weighs 0.33 lb, uses ABS that iClever says is BPA- and PVC-free and 50% stronger than standard, and pairs that with a reinforced button structure rated for double the presses. Rotating ear cups plus a 10-level headband adjustment cover heads aged 2 and up, and the protein leather cushions are there to avoid pressure on long trips. The 40 mm driver with low-frequency compensation and high-frequency enhancement is tuned for a clear, balanced result rather than thump.
What it is not: there is no app, no active noise cancellation (the noise control is passive), and controls are physical push buttons rather than touch. For a child, buttons are arguably the right call — they are harder to trigger by accident. Skip the BTH22 if you are buying for yourself and want adult-grade audio, ANC, or a low-latency mode for gaming. That is not what this product is for.
• Best for call clarity on the go → HARMONY TWENTY-TWO HTT-9. Four mics with ENC, voice assistant access, and a design built around your voice being heard.
• Best for hearing protection → iClever BTH22. 85 dBA ceiling, 74 dBA toddler mode, and targeted reduction of the 2K–4KHz range.
• Best for battery life → iClever BTH22. 60 hours on a charge versus 6 hours per bud charge on the HTT-9.
• Best for topping up fast → HARMONY TWENTY-TWO HTT-9. 10 minutes in the case yields about 100 minutes of playback.
• Best for low-latency video and gaming → HARMONY TWENTY-TWO HTT-9. The 45 ms latency figure is the relevant spec; the BTH22 lists no latency figure at all.
• Best for flights and long trips with kids → iClever BTH22. The 3.5 mm cable means the headphones keep working after the battery is done.
• Best for workouts and sweaty commutes → HARMONY TWENTY-TWO HTT-9. IPX5 protects against sweat and light rain; the BTH22 has no water-resistance rating listed.
• Best for durability against rough handling → iClever BTH22. Reinforced ABS and a button structure rated for double the presses.
• Best for a child aged 2+ → iClever BTH22. Rotating cups, 10-level headband adjustment, and a 0.33 lb weight.
• Best for one person who wants one pair of everyday earbuds → HARMONY TWENTY-TWO HTT-9.
In my opinion, these two do not compete for the same buyer, so the honest answer is to match the product to the person. If I were buying earbuds for myself — commuting, taking calls, gaming, walking in light rain — I would buy the HARMONY TWENTY-TWO HTT-9. The 13mm driver, Bluetooth 5.4, 45 ms latency, ENC call handling and the 10-minute charge that returns 100 minutes of playback are the features I would actually use.
If I were buying for a child, I would buy the iClever BTH22 without much hesitation. The 85 dBA cap with a 74 dBA toddler mode, the 60-hour battery, the wired backup and the reinforced build are precisely the things a parent worries about. Neither product is trying to be the other one, and that is fine. Check the current price on Amazon before you commit — the buttons on this page will show you where things stand today.
FAQ
No. It has ENC, which reduces background noise picked up by the microphones so callers hear you more clearly. Harmony states plainly that ENC does not reduce the noise you hear while listening — that would be ANC, which this model does not list.
iClever rates it at 60 hours, and about 75 hours in the 74 dBA toddler mode. At roughly four hours of use per day, that is around half a month between charges. When it does run down, the 3.5 mm cable keeps audio going.
Yes. It includes a 3.5 mm audio cable, so you can plug straight into a tablet, phone or in-flight entertainment system and keep listening with no battery at all. The HTT-9 has no wired option — it is Bluetooth only.
