• SIMOLIO Dual's biggest strength: Two infrared headsets and one transmitter that let two people adjust volume independently, plus Balance control for uneven left/right hearing and an ambient "MIC" mode.
• SIMOLIO Dual's biggest trade-off: Infrared needs a clear line of sight to the transmitter, with an optimal receiving distance of roughly 12 meters, so furniture, walls or bodies in the way can affect the signal.
• JBL Junior 470NC's biggest strength: A Safe Sound design that never exceeds 85dB, with a customizable lower limit, daily listening-time caps and PIN-protected settings in the JBL Headphones app.
• JBL Junior 470NC's biggest trade-off: It's a single pair of over-ear kids' headphones, so it can't serve two listeners at once, and it's built around limiting volume rather than maximizing it.
• Who each pick is for: SIMOLIO Dual for adults or seniors who want louder, clearer TV audio with per-ear tuning — JBL Junior 470NC for parents who want to cap how loud and how long a child listens.
The SIMOLIO Dual (model SM-863D) is an infrared TV listening system, not a general-purpose headphone. The box includes one infrared transmitter and two infrared headphones, along with optical, RCA and AUX cables and a power adapter. You plug the transmitter into the TV's audio output, power both units on, and there's no pairing step — the system simply works. That plug-and-play simplicity is the core of the appeal: no Bluetooth menus, no reconnecting, no dropped links mid-scene.
Volume is where this system earns its keep. Each headset has its own volume control, so two people watching the same TV can set completely different levels — one can crank dialogue while the other keeps things moderate. On top of that, the Balance control adjusts left and right ears separately, which is genuinely useful for anyone with asymmetrical hearing. A three-profile tone control (high, middle, low) lets you tune toward vocal clarity, and the "MIC" ambient mode pipes in nearby conversation without making you remove the headphones. A full charge takes about 3 hours and runs roughly 15 hours depending on volume and content, and the base doubles as a charging dock so the headsets just drop back in.
Who should buy it: couples or families where two people want to watch TV together at their own volumes, seniors who struggle with dialogue clarity, and anyone in a senior apartment or nursing home who wants private listening without blasting the room. The earbuds use memory foam tips and ear loops, which suits long sessions.
JBL Junior 470NC: Who It's For
The JBL Junior 470NC is designed around a single idea: protect young ears. Its Safe Sound design never exceeds 85dB, and you can set a limit even lower than that. Through the JBL Headphones app you can cap both maximum volume and daily listening time, then check daily and weekly reports on how long your child listened and at what level. A PIN code locks your settings so they can't be changed from the headphones themselves. That combination — hard ceiling, time limits, reporting, PIN — is the whole reason to buy this model.
The hardware is built for kids, not adults. You get durable, oversized control buttons that small hands can actually operate, a built-in mic for talking with teachers or family, and Active Noise Cancelling to shut out background noise so content stays enjoyable at lower volumes. Battery life is up to 50 hours with a 2-hour charge, and it connects over Bluetooth 5.3 — but JBL also includes a 3.5mm audio cable in the box, so it can run wired when needed. The over-ear design uses plastic, silicone and fabric, weighs 196g, and ships white with a sticker set for personalization.
Who should buy it: parents of younger kids who want enforceable, visible control over volume and screen-adjacent listening time, and households where a child uses headphones for school, video calls or entertainment. The 3.5mm cable makes it flexible for devices that don't do Bluetooth.
Who should skip it: anyone buying for an adult, or anyone who needs two people listening to the same source at independent volumes. This is one pair of headphones for one child, and its defining feature is a ceiling, not a boost. If you're chasing louder, clearer dialogue on a TV, this is the wrong tool.
Side-by-Side: Which Should You Choose?
• Best for two people watching one TV → SIMOLIO Dual. Two headsets and one transmitter, each with independent volume.
• Best for protecting a child's hearing → JBL Junior 470NC. The 85dB ceiling is the entire point of the design.
• Best for parental oversight → JBL Junior 470NC. App reports on volume and listening time, plus a PIN lock.
• Best for long battery life → JBL Junior 470NC. Up to 50 hours per charge versus roughly 15 hours on the SIMOLIO.
• Best for zero setup and no pairing → SIMOLIO Dual. Infrared connects automatically once powered on.
• Best for moving around the room → JBL Junior 470NC. Bluetooth 5.3 frees you from line-of-sight restrictions.
• Best for dialogue clarity on TV → SIMOLIO Dual. Its tone profiles and ambient mode are aimed squarely at that problem.
In my opinion, these two don't really compete — they solve opposite problems. If your goal is hearing the TV better, sharing it with a second person, and tuning each ear, I'd buy the SIMOLIO Dual. It's the only one of the two that lets two listeners run separate volumes off one source. If your goal is making sure a kid can't listen too loud or too long, I'd buy the JBL Junior 470NC, because that 85dB ceiling and the app controls are exactly what a parent needs. Pick based on the listener, not the brand. And if budget is the deciding factor, check the current price on Amazon for each before you commit.
how to disable volume control on wired headphones
There's no universal switch — inline volume on wired headphones is usually a physical wheel or slider, or handled by the device. On the JBL Junior 470NC, the 85dB cap is built into the headphone and managed through the JBL Headphones app, not something you toggle off with the 3.5mm cable.
do earbuds have volume control
Can two people listen to the same TV at different volumes?
Yes — with the SIMOLIO Dual. It ships with two infrared headsets and one transmitter, and each headset has its own volume control, so two viewers can set independent levels. The JBL Junior 470NC is a single pair of headphones and can't do this.
It works, but it's designed for kids: an 85dB maximum, time limits and PIN-protected parental settings. If you're an adult wanting louder, clearer TV audio with per-ear tuning, the SIMOLIO Dual is the better fit.
