• C G CHANGEEK 12Ft — biggest strength: an extra-long coiled cable that stretches to roughly 12 feet (about 3.5m), so you can sit back on the sofa or move around the room while staying plugged into a TV or desktop.
• C G CHANGEEK 12Ft — biggest trade-off: it is built around stationary, corded listening, so the dangling cable is not something you want to fight with during a run or a gym session.
• Avantree E171 — biggest strength: an ear-hook design plus three sizes of silicone tips, which gives a secure, snug fit aimed squarely at running, jogging and workouts.
• Avantree E171 — biggest trade-off: it is a standard short-cord earbud, so there is nothing here to help you reach across a living room; it is meant for a phone or device that travels with you.
• Who each is for: pick the C G CHANGEEK 12Ft if your priority is long-cable reach for TV and PC use; pick the Avantree E171 if your priority is a stable, workout-ready fit with in-line control.
The C G CHANGEEK 12Ft is, first and foremost, a length solution. The coiled cord extends to about 12 feet (350cm), and the 2021 revision added roughly 50cm (20 inches) of extra coiled length over the earlier version. That single design decision changes how you use a wired earbud. Instead of perching on the edge of the seat to keep the cable from tugging, you can settle back on the sofa, stretch out, or move around the room while the audio stays connected. It ships with a cable clip and a velcro tie, which tells you the designers understood that a long cord needs managing rather than fighting.
On the audio side, the specs point to 10mm dynamic drivers with a 20Hz–20kHz frequency range, 16 ohm impedance and 105dB sensitivity. In practice, that low impedance and high sensitivity combination is easy for phones, laptops and TVs to drive — you are not going to need a headphone amp to get usable volume out of a 3.5mm jack. The noise control is listed as sound isolation, so the sealed in-ear fit does the work of muting background noise rather than any active processing.
The controls are a genuinely practical touch for its intended audience. There is a sliding volume control on the cord, which means you can lower the TV volume without hunting for the TV remote — a small thing that matters a lot if you are the person in the house watching late at night. There is also a hands-free button for answering calls or switching songs, plus a built-in microphone that the brand positions for phone conversations and PC conference calls. A 3.5mm plug keeps it compatible with most smartphones, tablets, laptops and desktops that still have an analog jack.
So who should buy it? I'd point to anyone whose main listening happens at a fixed device — a TV, a desktop PC, a laptop on a desk — and who is tired of short cables. It is also a sensible pick for parents or older family members who want a simple, no-pairing, no-charging way to hear the TV better at their own volume, and the brand explicitly markets it that way. The sliding control is easier to find by feel than a touch panel.
Avantree E171: Who It's For
The Avantree E171 is designed around fit and movement. The spec sheet lists an ear-hook design, an over-ear earpiece shape and a silicone enclosure, and the package includes three different sizes of silicone earbuds. That combination — a hook that anchors the bud plus a choice of tip sizes — is the practical answer to the single most common complaint about cheap earbuds: they fall out. If you run, jog, lift or do anything that involves your head moving, the hook is doing real work that a plain bud cannot.
The sound is described as well-balanced with solid bass and an emphasis on mids and highs, and the brand notes that if you want extra-strong bass, larger headphones are the better route. That is a fair, honest framing rather than an overclaim, and it tells you what to expect: a clean, mid-forward tuning rather than a bass cannon. The dynamic drivers cover 20Hz–20kHz. One thing to flag from the spec sheet: the impedance is listed as 32 ohm and the sensitivity field oddly repeats "16 ohm" — that looks like a data-entry quirk in the listing, so I would treat the impedance figure as the reliable one and not read too much into the sensitivity number.
The in-line control is the other half of the story, and it is more feature-dense than the C G CHANGEEK's. Avantree lists play/pause, volume adjustment, track skipping, accepting or rejecting calls, activating the voice assistant, and redialing the last number. The built-in microphone is positioned for clear calls over phone or VoIP. The plug is gold-plated 3.5mm, which the brand says helps avoid distortion, and compatibility covers iPhones, Android phones, iPads, MP3/MP4 players, Macs, laptops, tablets, desktops and portable players. Warranty is 12 months, extendable to 24 months with product registration, with support channels including chat, email, phone and video guides.
Who should buy it? Runners, gym-goers, commuters and anyone who takes calls on the move and wants a physical button under their thumb rather than a touch surface or a voice command. The white colorway and the sports-and-exercise theme make the intended use obvious.
Side-by-Side: Which Should You Choose?
• Best for watching TV from the sofa → C G CHANGEEK 12Ft. The coiled cord reaches about 12 feet, so you are not tethered to the front of the screen.
• Best for running, jogging and the gym → Avantree E171. The ear-hook design plus three tip sizes is built for a secure fit during movement.
• Best for controlling TV volume without the remote → C G CHANGEEK 12Ft. The sliding in-line volume control is designed for exactly that.
• Best for phone and VoIP calls on the move → Avantree E171. Its in-line control handles accept/reject, redial, voice assistant and track skipping, with a mic tuned for calls.
• Best for PC conference calls at a desk → C G CHANGEEK 12Ft. The long cable and built-in mic suit a fixed desktop or laptop setup.
• Best for easy-to-drive audio from a phone or laptop → C G CHANGEEK 12Ft. At 16 ohm with 105dB sensitivity, it is an easy load for a basic 3.5mm output.
• Best for a two-year warranty path → Avantree E171. The coverage extends to 24 months with product registration, versus a flat 12 months.
• Best for older users or parents who want simplicity → C G CHANGEEK 12Ft. No pairing, no charging, a physical volume slider and a cable long enough to sit comfortably.
In my opinion, the C G CHANGEEK 12Ft is the one I would buy for the most common reason people search out a wired earbud in the first place: listening to a TV or a desktop PC without being chained to the device. The 12-foot coiled cable, the sliding volume control and the easy-to-drive 16 ohm, 105dB spec sheet all line up behind that single job, and the 2021 revision fixed the fit and added the mic. The Avantree E171 is a genuinely good product, but it solves a different problem — staying in your ears while you move — and if that is your problem, buy the E171 instead. Just match the product to the job, not the other way around.
FAQ
Yes, in my opinion. The 12Ft's coiled cable extends to roughly 12 feet and it has a sliding volume control designed so you can lower TV volume without the remote. The E171 is a standard short-cord earbud with no long-cable option.
The Avantree E171. It uses an ear-hook design with three sizes of silicone tips for a secure fit, and it is themed for sports and exercise. A 12-foot coiled cable is a liability while running.
Both use a standard 3.5mm jack, so both work with most phones, tablets, laptops and desktops that have an analog headphone port. Devices with only USB-C, Lightning, optical, coaxial, RCA or 6.35mm audio will need the matching adapter with either pair.
The Avantree E171 offers 12 months extendable to 24 months with product registration, plus chat, email, phone and video support. The C G CHANGEEK 12Ft carries a 12-month warranty. I would weigh that against the fact that the two products are built for different jobs in the first place.
Since I cannot quote prices here, check the current price on Amazon for both and compare them against the feature that actually matters to you — cable reach for TV and PC, or a secure ear-hook fit for sport. The right pick depends on the job, not the sticker.
