If you want one pair of wired headphones with a genuinely long cord and simple in-line volume control for TV and PC listening, choose C G CHANGEEK 18Ft; if you need wireless kids' headphones with a built-in mic, a safe volume ceiling and all-day battery, choose EarFun K2.
• C G CHANGEEK 18Ft — biggest strength: A spring coiled cord that stretches to 18FT / 5.5M, plus in-line volume control, so you can sit back and still reach the TV or PC.
• C G CHANGEEK 18Ft — biggest trade-off: Wired only, no microphone, and the in-line control reduces or mutes sound but cannot boost it above your TV's output level.
• EarFun K2 — biggest strength: Bluetooth 5.4 with a built-in mic, 40 hours of playtime, and 85/94dB volume limiting for kids.
• EarFun K2 — biggest trade-off: It's a kids' product sold as a 2-pack, and its volume story is a safety cap rather than a user-facing volume dial on the headphones themselves.
• Who each is for: C G CHANGEEK 18Ft suits adults, seniors and anyone who wants zero charging and zero pairing; EarFun K2 suits kids and teens who need wireless freedom and hearing protection.
The C G CHANGEEK 18Ft solves one problem extremely well: distance. Its spring coiled cord extends to 18FT / 5.5M, and before stretching it sits at roughly 4.8FT / 1.5M. That means you can leave the headphone plugged into the TV, walk to the kitchen for a refill, and still hear everything. The TPE cord is described as flexible and soft, so it stretches easily rather than yanking on your head.
The second thing it solves is simplicity. There's no battery, no pairing, no charging routine — you plug the 3.5mm AUX jack into a TV, laptop, desktop PC, CD player, MP3 player or phone and you're done. The in-line control lets you drop the volume or mute in seconds instead of hunting for the TV remote. That's a genuinely thoughtful detail for anyone who has ever fumbled through sofa cushions mid-show.
Two things to go in with your eyes open. First, the in-line control only reduces or mutes — it cannot amplify. If the maximum is still too quiet, you raise the volume on the TV itself. Second, there is no microphone, so this is not a headset for calls or voice input. The sound is tuned to a balanced preset from two 40mm NdFeB dynamic drivers, and C G CHANGEEK explicitly notes it isn't aimed at bass lovers.
EarFun K2: Who It's For
The EarFun K2 is built for a completely different user: a kid or teen, roughly ages 3 to 18, who needs headphones for school, travel, tablets and online tutoring. Its headline feature is the 85/94dB volume limit, which EarFun ties to the WHO recommended level for protecting young ears. That's the whole point of the product — the volume ceiling is the safety feature, not a convenience feature.
Around that sit some genuinely useful specs. Bluetooth 5.4 handles a stable wireless connection to iPads, Chromebooks and other Bluetooth devices. A built-in microphone enables hands-free calls and online classes, so a child can talk without holding anything. Battery life runs up to 40 hours, with a 2.5-hour USB-C recharge, and you also get a 3.5mm audio cable so listening can continue in wired mode once the battery runs out. The 40mm dynamic drivers cover a 20Hz–20kHz range with 32-ohm impedance and 100dB sensitivity.
Comfort and durability are clearly priorities too. The memory foam headband and earpads are meant for long wear, the ergonomic headband can be twisted and bent without breaking, and the foldable design packs down for school bags and trips. EarFun states the materials comply with RoHS2.0 and FCC standards and pass CPC certification, and the package includes a 2-pack along with an audio splitter adapter, cable and manual.
Who should buy it? Parents who want a wireless, mic-equipped, volume-capped pair for one or two kids. Who should skip it? Adults shopping for themselves — this is a kids' product, and its volume control philosophy is a protective limit rather than an adjustable dial. If you're an adult who wants to control loudness yourself, the C G CHANGEEK 18Ft's in-line control is the more relevant tool.
Side-by-Side: Which Should You Choose?
• Best for reaching across the room → C G CHANGEEK 18Ft. 18FT / 5.5M coiled cord versus a wireless range you don't have to think about but do have to charge.
• Best for adjustable listening volume in your hand → C G CHANGEEK 18Ft. The in-line control reduces and mutes instantly.
• Best for kids' hearing safety → EarFun K2. The 85/94dB limit is the defining feature.
• Best for calls and online classes → EarFun K2. It has a built-in mic; the C G CHANGEEK 18Ft has none.
• Best for battery life → EarFun K2. Up to 40 hours, plus a 2.5-hour USB-C recharge and a 3.5mm cable backup.
• Best for travel and packing → EarFun K2. Foldable, 175g, and supplied as a 2-pack with an audio splitter.
• Best for bass-forward listeners → neither, honestly. C G CHANGEEK states a balanced, non-bass preset; EarFun K2 is tuned for kids' content.
If I were buying for myself or for an older relative who just wants to watch TV without disturbing anyone, I would buy the C G CHANGEEK 18Ft. The 18FT coiled cord, the plug-and-play 3.5mm connection and the in-line volume control solve the exact problems that make wireless headphones annoying for that use case. If I were buying for a child heading to school or a tablet, I would buy the EarFun K2 — the 85/94dB limit, built-in mic and 40-hour battery are the right features for that job, and the 2-pack covers siblings. Different jobs, different answers. Just confirm your TV has a headphone or AUX OUT port before committing to the wired route, and check the current price on Amazon for both.
how to disable volume control on wired headphones
You can't disable the in-line control on the C G CHANGEEK 18Ft — it's a physical slider on the cable, not a software setting. Practically, you just leave it at maximum and control loudness from your TV, PC or phone instead. Note that the in-line control on this model only reduces or mutes; it never boosts volume above the source level.
do earbuds have volume control
Some do, some don't — it depends entirely on the model. The C G CHANGEEK 18Ft is an over-ear headphone, not an earbud, and it does include an in-line volume control on the cable. The EarFun K2 uses button-based media controls on the headphones themselves, and its volume approach is a fixed 85/94dB safety limit rather than a free-range dial.
That depends on your setup. The C G CHANGEEK 18Ft is wired over 3.5mm AUX, so it needs no charging or pairing — but your TV must have a headphone or AUX OUT port, or you'll need a USB, optical or RCA to 3.5mm adapter. The EarFun K2 is Bluetooth 5.4 with a 3.5mm cable included as a backup, which suits tablets and Bluetooth-capable sources.
Nothing in the specs restricts it by age, but it isn't designed as a kids' product. It has no volume-limiting feature, so a child could turn it up as loud as the source allows. If hearing protection matters to you, the EarFun K2's 85/94dB limit is the safer design choice.
