How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a headset built for long work calls and hands-free talking, choose RAOPINGX MERAIJIN Trucker; if you need volume-limited headphones for a child's ears, choose Puro Sound Labs. These two wireless on-ear Bluetooth headphones sit in completely different lanes, and picking the wrong one is mostly a matter of ignoring what you actually need them for.
• RAOPINGX MERAIJIN Trucker — biggest strength: A boom microphone with active noise cancellation and a claimed 16–17 hours of talk time, built around clear voice pickup in noisy places.
• RAOPINGX MERAIJIN Trucker — biggest trade-off: It's a specialist. The design and feature set are aimed at calls, not at kids, not at critical music listening, and there's no volume limiting.
• Puro Sound Labs — biggest strength: Volume capped at 85 dB with noise isolation rated up to 87% of ambient sound, plus a lighter 22-hour battery and fast USB-C charging.
• Puro Sound Labs — biggest trade-off: The 85 dB ceiling is the whole point, so it will never get loud — which is wrong for an adult who wants punchy output in a loud environment.
• Pick RAOPINGX MERAIJIN Trucker if: you're a driver, dispatcher, or anyone on calls all day who needs a mic and long talk time.
• Pick Puro Sound Labs if: you're buying for a child and hearing safety matters more than anything else on the spec sheet.
This is a single-purpose tool, and it's honest about it. The M97 is an on-ear headset with a rotating boom microphone, Bluetooth 5.0, and a range of up to 33 feet. The mic uses active noise cancellation to pull your voice out of a noisy cab or office and push the background down. That's the core of the product — the drivers are dynamic with a 20 Hz to 20,000 Hz range, but nobody buys this for the driver tuning. They buy it so the person on the other end of the call can hear them.
The battery story is the other headline. The spec sheet claims up to 16 hours of continuous talking and 180 hours of standby, with a full charge in about 2 hours. The description repeats similar figures — around 17 hours of talking and 200 hours of standby — so treat the exact number as approximate, but the shape of it is clear: this is a headset you charge overnight and wear through a shift. It recharges by dropping onto a charging base with micro USB, which is a genuinely nice detail if you work from a fixed spot like a truck cab or a desk. No hunting for a cable.
Comfort is pitched at long wear. It weighs 1.8 oz, uses a padded flexible headband, and the microphone rotates 330 degrees so you can park it on whichever side you prefer. It pairs with two devices at once, so you can keep a phone and a tablet or PC connected and switch between music and calls without re-pairing. It works with Android and iOS.
Who should buy it: drivers, call center staff, remote workers on back-to-back voice calls, anyone who wants a boom mic and doesn't care about premium audio. Who should skip it: kids (there's no volume limiting at all), and anyone who wants a headphone primarily for music, movies, or gaming — the call-first design and plastic on-ear build aren't aimed at that.

The JuniorJam Plus is designed around one non-negotiable idea: protect a child's hearing. Output is capped at 85 dB, and the sensitivity spec confirms that 85 dB figure rather than just marketing it. For a parent, that single number is the reason to buy this and the reason to skip everything else on the shelf. Ordinary headphones let a kid crank the volume until it hurts; this one physically won't.
The surprise is that the sound isn't a compromise. Puro's Balanced Response Curve, dynamic drivers, and a 20 Hz–20,000 Hz range mean the tuning is aimed at clarity and usable bass even under the volume ceiling. Puro also rates the isolation at up to 87% of ambient noise, which matters more than people think — if outside sound is blocked, a kid doesn't feel the need to turn it up in the first place. Noise control here is sound isolation, not active cancellation, so plan for passive blocking rather than a silence bubble.
Battery and connectivity are modern. Bluetooth 5.1 with a 30-foot range, up to 22 hours of playtime, and a full charge in about 60 minutes over USB-C. That's a faster charge than the RAOPINGX headset and a longer rated runtime, though it's playtime rather than talk time, so the two numbers aren't directly comparable. It's wired and wireless capable, connects two devices at once, has a foldable frame, and adjusts to fit kids through teens. Controls are touch-based. The package includes a storage bag, audio and USB-C cables, and a sharing cable, and it carries a one-year warranty. The purple leather on-ear design is squarely aimed at younger listeners.
Who should buy it: parents of younger kids through teens, for home, school, and travel. Who should skip it: adults who want volume, anyone who needs a boom mic for calls, and anyone working in a genuinely loud environment where 85 dB just won't cut through. Check the current price on Amazon before deciding.
• Best for voice calls and a boom mic → RAOPINGX MERAIJIN Trucker. The rotating mic and active noise cancellation are built for exactly this.
• Best for protecting a child's hearing → Puro Sound Labs. The 85 dB cap is the entire reason this product exists.
• Best for long talk sessions → RAOPINGX MERAIJIN Trucker. Up to 16–17 hours of continuous talking with a 180–200 hour standby figure.
• Best for long listening sessions → Puro Sound Labs. Up to 22 hours of playtime with a 60-minute USB-C charge.
• Best for a fast recharge → Puro Sound Labs. One hour to full versus roughly two hours for the RAOPINGX.
• Best for a charging dock workflow → RAOPINGX MERAIJIN Trucker. Drop it on the base and forget it.
• Best for noise blocking → Puro Sound Labs. Rated at up to 87% ambient isolation, though via passive isolation rather than cancellation.
• Best for fitting growing kids → Puro Sound Labs. Lightweight, flexible, foldable, and adjustable from little ones to teens.
• Best for pairing two devices at once → either. Both support dual connections, so this one's a tie.
If I had to pick one, it depends entirely on the job — and I'd pick RAOPINGX MERAIJIN Trucker for myself, because a boom mic with noise cancellation, a charging base, and 16-plus hours of talk time solves a concrete problem I actually have. In my opinion, the Puro Sound Labs JuniorJam Plus is the better buy for its intended buyer: a parent who wants their kid to listen safely without wrecking their hearing. Buy the RAOPINGX for calls. Buy the Puro for a child. Buying the wrong one isn't a bad product — it's a bad match.
how do wireless bluetooth headphones work
They connect to a phone, tablet, or computer over a short-range Bluetooth radio link instead of a cable. The RAOPINGX MERAIJIN Trucker uses Bluetooth 5.0 with a range up to 33 feet, and the Puro Sound Labs uses Bluetooth 5.1 with a range up to 30 feet. Both stream audio wirelessly and both can hold two paired devices at once.
how to put wireless headphones in pairing mode
On the RAOPINGX MERAIJIN Trucker, you turn the headset off, then long-press for 5–8 seconds until the LED flashes blue and red alternately — that's pairing mode. Once paired, it works with Android and iOS devices within range. The Puro Sound Labs pairs the same way any Bluetooth 5.1 headphone does; the key is making sure the headset isn't already connected to another device first.
how connect bluetooth headphones to phone
Turn the headphones on, put them into pairing mode, then open your phone's Bluetooth settings and select the headset from the list. The RAOPINGX MERAIJIN Trucker pairs with any Bluetooth-enabled phone, tablet, PC, or iPad within roughly 33 feet. If the volume still feels low after that, the manufacturer notes you should also raise your phone's own volume, not just the headset's.
how to connect sony wh ch520 on ear wireless bluetooth headphones
That's a different brand with its own pairing routine, so follow Sony's instructions for that model rather than anything here. The general process is identical, though: power on, enter pairing mode, then select the headphones in your phone's Bluetooth menu. The same steps apply to the two on-ear headphones compared on this page.
