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 on-ear headphone built around a single pair with a microphone, an inline remote, a tangle-resistant braided cable and a two-year warranty, choose ELECDER i45; if you need two lightweight retro-styled pairs in one box for sharing, travel or keeping a backup, choose Tnyvm 2.
• ELECDER i45 biggest strength: A 40 mm dynamic driver paired with a microphone and in-line media controls on a nylon-braided, tangle-free 1.5 m cord — a complete single-headphone package for calls, classes and playlists.
• ELECDER i45 biggest trade-off: It is one headphone, not a pair of two, and it relies on a 3.5 mm wired jack, so devices without a headphone port need an adapter.
• Tnyvm 2 biggest strength: You get two foldable on-ear headphones in one box, each with an adjustable headband, cushioned pads and a retro look — instant sharing or a spare.
• Tnyvm 2 biggest trade-off: No microphone, no in-line controls, no stated warranty, and the spec sheet lists a very light 9.07 g build that signals a simpler, more basic construction.
• Who the ELECDER i45 is for: One person who wants a do-everything wired headphone for school, travel, tablets and phones.
• Who the Tnyvm 2 is for: Two people, or one person who wants a nostalgia-styled set plus a backup for cassette players and older gear.
The ELECDER i45 is the more feature-complete of the two. Its core is a 40 mm dynamic driver, which is the piece of hardware responsible for the low end — the listing frames it as Hi-Fi stereo bass with a crisp midrange, and a driver that size is generally what gives an on-ear headphone some weight behind drums and basslines rather than a thin, tinny sound. The ear cushions are padded and the headband is adjustable via a size slider, so it should settle onto a range of head sizes rather than clamping in one spot.
What separates it from the Tnyvm 2 is everything around the driver. There is a microphone and in-line media control, so you can take a call or skip tracks without touching your phone. The cable is 1.5 m of nylon-braided fabric, which is the practical answer to the tangled-ball problem that kills cheap wired headphones. And the foldable design plus the adjustable slider make it genuinely portable — it collapses down for a backpack pocket, which matters if you are carrying it to class, onto a plane, or between home and an office.
The sound isolation is described as a passive effect of the padded cushions rather than active noise cancellation, so expect it to soften background chatter, not erase it. The brand also notes the ear cushions help protect children's ears up to 85 dB, which is a nod toward the school and kid-friendly use cases in the product title.
Tnyvm 2: Who It's For
The Tnyvm 2 takes the opposite approach: instead of packing features into one headphone, it gives you two. The box contains two black on-ear headphones, each with an adjustable headband, cushioned ear pads and a foldable, lightweight build. The styling is deliberately retro, and the listing points at cassette players as a natural companion — which tells you this is aimed at people who like the look and feel of older audio gear, or who want a cheap, simple wired headphone for a specific old device.
The specs are modest and honest about it. Impedance is 32 ohm with a 20 Hz – 20,000 Hz frequency range, which is the standard full-range window most consumer headphones cover. It uses passive noise cancellation, meaning the cushioned pads physically block some outside sound rather than any electronics doing the work. There is no microphone, no in-line control, and the warranty description simply reads "No." The listed item weight is just 9.07 g, which is extremely light — good for comfort over long sessions, but it also tells you the materials are basic, with a metal-and-plastic enclosure.
The two-pack is the real selling point. One pair for you, one for a friend, a sibling or a partner. Or one for the desk and one for the bag. For households where headphones get lost, borrowed or broken, having a spare in the same box is a genuinely useful thing.
Who should buy it: someone who wants two simple, light, retro-looking wired headphones for sharing, cassette players or backup duty. Who should skip it: anyone who needs to take calls, control playback from the cable, or wants a warranty behind the purchase.
Side-by-Side: Which Should You Choose?
• Best for calls and voice chat → ELECDER i45. It has a built-in microphone and in-line media control; the Tnyvm 2 has neither.
• Best for cable durability → ELECDER i45. The nylon-braided, tangle-free 1.5 m cord is designed to survive daily bag life.
• Best for a retro or cassette-player setup → Tnyvm 2. The styling is explicitly retro and the listing calls out cassette players.
• Best for bass and fuller sound → ELECDER i45. Its 40 mm dynamic driver is the more substantial audio hardware of the two.
• Best for all-day light comfort → Tnyvm 2. At a listed 9.07 g with cushioned pads, it is built to disappear on your head.
• Best for peace of mind → ELECDER i45. It comes with a stated 24-month warranty; the Tnyvm 2 lists no warranty.
• Best for a kid's first headphone → ELECDER i45. Adjustable fit, foldable build and the 85 dB ear-protection note fit school and young listeners.
I would buy the ELECDER i45. In my opinion it is the better standalone headphone: a 40 mm dynamic driver, a microphone, in-line controls, a braided tangle-free cable, a foldable adjustable frame and a 24-month warranty add up to one product that handles music, calls and travel without excuses. The Tnyvm 2 only wins on one axis — two pairs instead of one — and if that is your actual need, or you specifically want the retro look for a cassette player, it is the right call. Otherwise, the i45 does more per listener.
what are the best open ear headphones
Neither of these is an open-ear design — both are on-ear headphones, which rest on the ear rather than sitting outside it. So neither fits that category. If open-ear is what you want, look for a model explicitly described that way; between these two, the choice comes down to features (ELECDER i45) versus a two-pack (Tnyvm 2).
are on ear headphones good
They can be, and both of these are on-ear models. On-ear headphones are generally lighter and more portable than over-ear ones, and the cushioned pads here provide passive isolation. Their main trade-off is less sound isolation than over-ear designs, which matters in loud places like planes or busy trains.
are open ear headphones good
Open-ear headphones let in ambient sound, which some people prefer for safety and awareness, but it also means less bass and less isolation. That is not what either the ELECDER i45 or the Tnyvm 2 is — both are wired on-ear headphones with padded cushions that block some outside noise.
what are the best in-ear headphones
That is a different product category entirely, and neither the ELECDER i45 nor the Tnyvm 2 is an in-ear model — both are on-ear. If you specifically want in-ear, neither of these is the answer. If you want an on-ear wired headphone, choose the i45 for features or the Tnyvm 2 for two pairs.
