How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a compact, low-latency true-wireless set for gym work, runs and poolside laps, choose Aoslen Earbuds; if you need a volume-limited, kid-sized over-ear headset for a toddler or young child, choose iClever BTH27. Those are genuinely different jobs, which is why this comparison matters — and why "for swimming" keeps coming up. Neither product is a bone-conduction swim headphone, so if you specifically want the best long battery life bone conduction headphones for swimming, you are looking at the wrong pair entirely. What follows is a spec-based look at what each set actually is.
• Aoslen Earbuds biggest strength: true-wireless in-ear design with Bluetooth 5.3, a claimed 15 m range, 13 mm dynamic drivers, four ENC mics, 6–7 hours per charge and a charging case that extends total playback to about 42 hours.
• Aoslen Earbuds biggest trade-off: in-ear buds mean small parts to lose, no headband or ear-cup structure, and the IP rating is described inconsistently in the listing (IP6 in one bullet, IP7 in another), so I would treat water resistance as splash-and-sweat level, not swim-proof.
• iClever BTH27 biggest strength: child-specific design — 75/80 dBA dual-mode volume limiting, Sound Refiner tuning, BPA-free materials, a flexible headband with 10-level extendable arms, and up to 74 hours of battery life with a 10-minute quick charge giving roughly 8 hours.
• iClever BTH27 biggest trade-off: it is built for small heads and young ears, with a stated frequency range of 20 Hz–4 kHz, so it deliberately cuts high frequencies and is not a serious listening headphone for adults or for detailed music.
• Who each pick is for: Aoslen Earbuds for an adult who wants pocketable wireless earbuds for workouts and calls; iClever BTH27 for a parent who wants a safe, durable, volume-capped headset for a toddler or young child.
The Aoslen A60Pro is a classic true-wireless in-ear package. Two buds, a charging case, Bluetooth 5.3, and a 15-metre claimed connection range. The spec sheet lists 13 mm dynamic drivers, a 20 Hz–20,000 Hz frequency range, 32 ohm impedance, four ENC microphones, touch and voice controls, and a USB-C case that recharges in about 1.5 hours. Each bud is rated for around 6.5 hours of playback, with the case pushing total listening toward 42 hours. The earbuds also carry an LED battery display so you can see the charge level of each bud and the case.
Who should skip it? Anyone shopping for a child's headset. There is no volume limiter here, no headband, and the ear tips are small enough to be a choking hazard around very young kids. Also skip it if you want true swim headphones: the water resistance claim is aimed at sweat, rain and splashes, not submersion. For swimming specifically, a headset for swimming usually means bone conduction with an IP68-style rating and onboard storage — neither of these two products is that.
iClever BTH27: Who It's For
The iClever BTH27 is a purpose-built kids' headphone, and the spec sheet reads like it. The headline feature is a dual-mode volume limiter at 75 dBA and 80 dBA, with the lower setting intended for younger, more delicate ears. On top of that, iClever's Sound Refiner softens harsh frequencies in the 2 kHz–4 kHz band, which is exactly the range that makes cheap kids' headphones sound shrill. Materials are BPA-free and described as meeting ASTM safety standards, with soft leather ear cushions.
The physical design is all about small heads. Child-sized ear cups, a flexible headband, 110° rotating ear cups and 10-level extendable arms that grow with your child. It folds for storage, and the buttons are oversized and raised so a small kid can find play/pause without help. Weight is listed at 160 g. Battery life is the other standout: up to 74 hours, or roughly 15 days at 4–5 hours a day, with a 10-minute Type-C charge giving about 8 hours. If the battery runs flat, there is a 3.5 mm jack and a bundled cable so it keeps working as a wired headphone.
That wired fallback is a bigger deal than it sounds. It means the headset never becomes a dead plastic shell on a long trip. Bluetooth 5.4 handles the wireless side, pairing with phones, tablets and iPads, with a claimed range of about 33 feet. There is a 12-month warranty listed.
Who should skip it? Adults, teens, and anyone who wants full-range music. The stated frequency range tops out at 4 kHz, which is a deliberate hearing-safety choice, not a defect — but it also means cymbals, sibilance and air are simply not there. It is a child's tool, not a hi-fi product.
• Best for a toddler or young child → iClever BTH27. Volume limiting, BPA-free materials, rotatable cups and extendable arms are all built for kids.
• Best for adult workouts and running → Aoslen Earbuds. Compact in-ear fit, three ear-tip sizes, and splash/sweat-level water resistance.
• Best for long battery life → iClever BTH27. Up to 74 hours versus roughly 42 hours of total case-included playback on the Aoslen.
• Best for call clarity → Aoslen Earbuds. Four ENC microphones with voice-boosting processing are aimed squarely at phone calls.
• Best for low-latency video and gaming audio → Aoslen Earbuds. Bluetooth 5.3 with lossless-style audio coding and lower-latency transmission is the relevant spec here.
• Best for travel with a child → iClever BTH27. Folding design, wired 3.5 mm fallback, and a 10-minute charge that buys about 8 hours.
• Best for pocketability → Aoslen Earbuds. A charging case beats a folding headband for slipping into a jacket pocket.
• Best for swimming → neither. If that is your goal, look for a dedicated bone-conduction swim headphone with onboard memory instead of either of these.
If I were buying for myself, I would take the Aoslen Earbuds. Bluetooth 5.3, 13 mm drivers, four ENC mics, a 42-hour case and a small in-ear form factor cover the everyday adult use case — commuting, calls, workouts, video — better than a volume-capped kids' headphone ever could. If I were buying for a 2-to-5-year-old, I would take the iClever BTH27 without hesitation: the 75/80 dBA limiter, Sound Refiner tuning, BPA-free build and 74-hour battery are exactly what a parent needs. And to repeat the one thing worth repeating: if your actual target is music for swimming, skip both and buy a real swim-rated bone conduction pair. Check the current price on Amazon for whichever one you land on.
FAQ
how to bluetooth headphones to ps5
how to bluetooth headphones to xbox
Xbox consoles likewise do not support generic Bluetooth audio. You would need either a transmitter plugged into the controller's 3.5 mm jack or a Bluetooth adapter for the console, then pair the headphones to that. Because the iClever BTH27 supports wired 3.5 mm input, it can plug straight into an Xbox controller with the included cable and skip Bluetooth entirely.
how to bluetooth headphones to roku tv
Roku TVs and Roku streaming players do not send audio over standard Bluetooth to headphones. The common solution is the Roku mobile app's private listening mode, which routes TV audio to your phone — pair the Aoslen Earbuds or the iClever BTH27 to your phone, and the phone becomes the audio receiver. Alternatively, a Bluetooth transmitter on the TV's audio output works.
how to bluetooth headphones
Turn the headphones on and put them into pairing mode — on the Aoslen Earbuds, opening the charging case triggers automatic pairing and reconnection to the last device; on the iClever BTH27, use the power/pairing control. Then open your phone or tablet's Bluetooth settings, select the device from the list, and confirm. Both use Bluetooth (5.3 and 5.4 respectively) and reconnect automatically to previously paired devices afterward.
