How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired in-ear monitor built for serious music listening and a replaceable cable you can keep for years, choose erjigo in-Ear Monitors; if you need a plug-and-play USB-C headset with an inline mic for video calls, choose AFGHOA USB C Headphones. These two look similar on a shelf, but they solve completely different problems — one chases hi-fi stereo sound, the other chases convenience and clear voice pickup. If your day is built around video calls, meetings and online classes, that difference decides everything.
• erjigo's biggest strength: a six-driver hybrid setup (one dynamic driver plus five balanced armatures) tuned for a wide, articulate hi-fi stereo stage, with a 7 Hz–40 kHz range.
• erjigo's biggest trade-off: it's a 3.5 mm wired, mic-free monitor. There's no inline microphone on this version, so it isn't the tool for calls.
• AFGHOA's biggest strength: a USB-C plug with an inline mic and button controls — answer/end calls, play/pause, skip tracks, adjust volume, wake a voice assistant.
• AFGHOA's biggest trade-off: a single dynamic driver with a 2000 Hz–20,000 Hz range and a fixed cable. No detachable cable, no hybrid driver array.
• Buy erjigo if you're a musician, mixer or detail-obsessed listener who plugs into a 3.5 mm source.
• Buy AFGHOA if you live on USB-C devices and want one cable for calls, classes and casual listening.
The erjigo in-Ear Monitors (KZ ZSX) is a hybrid IEM: one dynamic driver handles the low end while five balanced armatures carry the mids and highs. That combination is the whole point of the product — it's designed to produce a balanced, powerful and articulate sound stage rather than a bass-forward consumer thump. Sensitivity is rated at 111 dB/mW with a 24 ohm impedance, and the frequency range runs from 7 Hz all the way to 40 kHz. In plain terms, that's a monitor spec sheet built for people who listen closely, not casually.
The build backs that up. The shell uses a zinc alloy cover with an imported resin cavity, so the edges are cut-proof and the finish is meant to keep its shine over long use. The lower shell was redesigned around ergonomics for better wearing stability, and at 31 g the whole thing stays light enough for long sessions. The detachable 0.75 mm 2-pin cable is the detail I appreciate most: you can swap cables, extend the earphones' working life, and change the sound signature without replacing the whole unit. The 3.5 mm gold-plated L-shaped plug reduces signal loss and fits computers, tablets, phones and players.
Who should buy it? Musicians, home-studio users, gamers who want positional detail, and anyone who already owns a decent DAC or amp and wants an affordable hybrid monitor. It also suits people who hate the idea of a sealed, disposable headset. Who should skip it? Anyone whose main job is talking. This version ships without a microphone, and it terminates in 3.5 mm — so if you're hunting for a volume limiting wireless headset for video calls, or anything with a built-in mic, this isn't it. It's also a wired, in-ear design with sound isolation rather than active noise cancellation or a transparency mode.
The AFGHOA USB C Headphones are built around a single idea: one cable, plugged straight into a modern USB-C port, doing voice and music at the same time. AFGHOA uses a dedicated DAC chip inside the plug to deliver lossless audio and to stay compatible across older and newer USB-C audio ports. The driver is a dynamic type, rated 32 ohm, 105 dB sensitivity, with a 2000 Hz–20,000 Hz frequency range. The in-ear fit provides passive sound isolation, so background noise gets pushed down without any battery or pairing.
The feature that matters most for calls is the inline microphone and button remote. You can answer, end and reject calls, play and pause music, skip tracks, adjust volume and wake Siri — all from the cable. That makes it a genuinely practical headset for online courses, conferencing, gaming, study and office use. The cable is 1.5 m (about 4.9 ft) with a ribbed, line-cut surface designed to survive repeated bending, and it's longer than most earbuds in this category, which gives you real slack when you move. You also get wingtips to help the buds stay put, plus a zipper carrying case. AFGHOA lists an 8-month worry-free warranty.
Compatibility is unusually broad: iPhone 17/16/15 families, a long list of Samsung Galaxy S and A models, Google Pixel, iPad Pro/Air/Mini, Kindle Fire Max 11, OnePlus, MacBook Pro, Surface laptops and more. Who should buy it? Students, remote workers, commuters and anyone whose laptop or phone no longer has a headphone jack. Who should skip it? If you want to swap cables, chase a hybrid driver array, or plug into a 3.5 mm interface, this isn't the right tool — the cable is fixed and the audio design is simpler.
Side-by-Side: Which Should You Choose?
• Best for hi-fi stereo sound quality → erjigo in-Ear Monitors. Six drivers and a 7 Hz–40 kHz range versus one dynamic driver at 2000 Hz–20,000 Hz.
• Best for modern phones and laptops → AFGHOA USB C Headphones. USB-C covers iPhone 15 and later, most recent Samsung Galaxy, Pixel, iPad, MacBook and Surface.
• Best for older gear and audio interfaces → erjigo in-Ear Monitors. The 3.5 mm gold-plated plug fits computers, tablets, players and dedicated audio hardware.
• Best for long-term ownership → erjigo in-Ear Monitors. The 0.75 mm 2-pin detachable cable means a broken cable doesn't kill the earphones.
• Best for cable length and movement → AFGHOA USB C Headphones. The 1.5 m reinforced cable is longer than most rivals.
• Best for a secure, stable fit → tie, with different approaches. erjigo leans on an ergonomically redesigned shell; AFGHOA adds wingtips.
• Best all-rounder for a student or hybrid worker → AFGHOA USB C Headphones. Calls, classes and music in one cable, with a case and a warranty.
In my opinion, most people shopping this comparison should buy the AFGHOA USB C Headphones. The reason is simple: it does the job most of us actually have — video calls, classes, meetings and everyday listening — through one USB-C cable, with a mic and controls built in. The erjigo in-Ear Monitors are the better-sounding, better-built audio tool, and if you're a musician or a detail-focused listener with a 3.5 mm source, I'd pick them without hesitation. But a mic-free monitor can't run your calls. If you want a volume limiting wireless headset for video calls, a transparency mode bluetooth headset, or the best crystal clear calls gaming headset for video calls, this AFGHOA wired option still covers the call side cleanly — just check the current price on Amazon before you commit. For everyone else, AFGHOA is the safer, more useful buy.

Neither product here is wireless. The erjigo in-Ear Monitors are wired with a 3.5 mm jack (the listing notes Bluetooth under wireless technology, but the connection is a wired 3.5 mm plug), and the AFGHOA USB C Headphones are wired with a Type-C connector and no wireless technology. If wireless is a hard requirement, both are the wrong category.

For hi-fi stereo sound, the erjigo in-Ear Monitors are the stronger pick on paper: one dynamic driver plus five balanced armatures, 24 ohm impedance, 111 dB/mW sensitivity and a 7 Hz–40 kHz range. The AFGHOA set uses a single dynamic driver with a 2000 Hz–20,000 Hz range. In my opinion erjigo wins on pure audio hardware; AFGHOA wins on convenience.

do these headphones have a microphone for video calls?
The AFGHOA USB C Headphones do — an inline mic with button controls for answering calls, adjusting volume and waking a voice assistant. The erjigo in-Ear Monitors in this version ship without a microphone, so for video calls the AFGHOA pair is the one to choose.
