If you want a wired on-ear headphone with a detachable cable, a swappable mic option and a fold-flat design for music and calls at a desk or on a commute, choose ALTEAM On-Ear Headphone; if you need a lightweight in-ear with a bass-forward tuning, a tangle-resistant flat cable and an ergonomic fit for long listening sessions, choose erjigo in-Ear Earbuds Headphones.
• ALTEAM's biggest strength: a full-size on-ear build with 40mm drivers, a detachable cable system and two cables in the box — one with an inline mic and one silver-plated for music.
• ALTEAM's biggest trade-off: it's the bulkier option of the two, and the on-ear fit means you're wearing a headband, not a tiny bud — plus the cable is a separate piece you have to keep track of.
• erjigo's biggest strength: a genuinely pocketable in-ear with a 10mm dynamic driver, a 34Ω impedance and a flat oxygen-free copper cable that resists tangling.
• erjigo's biggest trade-off: the variant here is the without mic version, so there's no hands-free calling — and in-ear fit is personal, so comfort depends on your ear shape.
• Who each is for: ALTEAM suits someone who wants one wired headphone for music and phone calls at a desk or on a train; erjigo suits someone who wants the smallest, lightest wired option for music on the move.
The ALTEAM is the more "complete system" of the two. It's a wired on-ear headphone built around 40mm driver units, which is a large driver for this category — the kind of size that usually translates to a fuller low end and a wider sense of space than a small bud can manage. The spec sheet lists a frequency range of 10Hz–20kHz with a 40kHz frequency response figure and 50Ω impedance, so it's aiming at the hi-res, detail-first listener rather than someone chasing maximum loudness from a weak source.
What I like most about the design is the cable flexibility. The detachable cable means you can run the silver-plated cable for serious music listening and switch to the inline-mic cable when you need to take a call. That inline button handles play/pause and call receive, so you're not pulling your phone out every time it rings. The fold-flat, swivel ear cups collapse down for storage, and it ships with a travel drawstring bag — a small thing, but it makes the headphone far easier to live with than a fixed, non-folding pair.
Buy it if you want a single wired headphone that handles music and calls, you like having a spare cable and a carry bag, and you don't mind a bit of bulk. Skip it if you want something you can shove in a jeans pocket, or if you only ever listen to music and never take calls — the extra cable and mic hardware are wasted on you.
erjigo in-Ear Earbuds Headphones: Who It's For
The erjigo is the opposite philosophy: strip everything down to the smallest possible package and put all the effort into the sound and the fit. It's a wired in-ear built around a 10mm high-polymer diaphragm dynamic driver, tuned for what the spec sheet describes as bass-driven, crystal-clear sound with a natural soundstage. The polymer composite diaphragm is described as light, thin and highly elastic — the design intent being clear vocals and instruments without muddiness.
The numbers back up the "easy to drive" angle: 34Ω impedance and 105dB sensitivity, with a 20Hz–40kHz frequency range. Lower impedance and higher sensitivity together generally mean a phone or laptop can push these to a decent volume without a separate amp. If you mostly listen straight out of a handset, that matters.
Fit is where in-ears live or die, and the erjigo leans into an ergonomic cavity structure with a lightweight shell and a PU memory ear hook to spread pressure around the auricle. The promise is no pressure even after long wear. The housing mixes a metallic surface with a resin cavity, which also gives it a more premium look than the price-sensitive in-ear norm. The cable is an OFC double-line parallel flat cable, 125+5cm long, with a 0.75mm pin type — flat cables resist tangling and knotting far better than round ones, and oxygen-free copper is the standard choice for clean signal transmission. There's a remote media control on the cable.
Buy it if you want a light, pocketable wired in-ear, you listen mostly to music on a phone, and you like a bass-forward tuning with a clean top end. Skip it if you need to take calls — this is the without mic variant, so there's no microphone and no call handling. Also skip it if you know you dislike deep in-ear fit; on-ear designs like the ALTEAM are a safer bet for you.
• Best for phone calls → ALTEAM On-Ear Headphone. The inline mic cable and one-button call receive are the whole point of that second cable.
• Best for pure music listening on the go → erjigo in-Ear Earbuds Headphones. Smaller, lighter, no headband, flat tangle-resistant cable.
• Best for portability → erjigo. Two tiny buds versus a folding on-ear with a bag.
• Best for storage versatility → ALTEAM. Fold-flat swivel cups plus a drawstring travel bag, and the cable detaches so nothing gets bent in transit.
• Best for a bass-forward, easy-to-drive tuning → erjigo, given the 10mm dynamic driver, 34Ω impedance and 105dB sensitivity.
• Best for a bigger, more open presentation → ALTEAM, on the strength of 40mm drivers and the silver-plated detachable cable.
• Best for long-session comfort if you hate things in your ear canal → ALTEAM. Soft foam, faux leather cushions, adjustable headband and soft head strap.
• Best if cable durability is your worry → erjigo. The OFC flat parallel cable is explicitly designed to resist tangling and last longer.
In my opinion, this comes down to one question: do you need a microphone? If yes, the ALTEAM On-Ear Headphone is the pick — you get music and hands-free calls, two cables, a folding frame and a carry bag, all in one box. If you only listen to music and want the smallest thing that still sounds serious, I'd take the erjigo in-Ear Earbuds Headphones: the 10mm dynamic driver, the 34Ω/105dB spec and the tangle-resistant flat cable make it the more convenient everyday companion. I'd buy the ALTEAM for a desk-and-commute setup and the erjigo for pocket music. Check the current price on Amazon before you decide, since that gap is usually what settles it.
Yes. The ALTEAM ships with an inline microphone cable and a one-button control for receiving calls, while this erjigo variant is the without-mic version, so it has no microphone at all.
The erjigo. It's a lightweight in-ear with a small metallic-and-resin housing and a 125+5cm flat cable. The ALTEAM folds flat and comes with a travel bag, but it's still a full on-ear headphone with a headband.
Probably not. The erjigo lists 34Ω impedance and 105dB sensitivity, which is easy to drive from a phone. The ALTEAM is 50Ω, still manageable from most phones, tablets and laptops with a 3.5mm jack.
The erjigo is explicitly tuned as bass-driven with a 10mm dynamic driver. The ALTEAM's 40mm drivers give a bigger, more open presentation with punchy bass as well. Which you prefer is really about fit preference, not just the numbers — if you want a fuller, more spacious feel, go ALTEAM; if you want tight, in-your-head bass, go erjigo.
