How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want lightweight open-ear earbuds that stay hooked on your ears during a run and plug straight into a 3.5mm jack, choose Jiunai Open Ear; if you need wireless over-ear headphones for late-night TV watching with a charging stand and a transmitter in the box, choose ZUPVIY Headphones. These two products only look like competitors on a search results page. In reality they solve completely different problems, and the specs make that obvious the moment you line them up.
• Jiunai Open Ear — biggest strength: a true 3.5mm wired connection with 90° right-angled buds, 15° adjustable over-ear hooks, a cord clip, and a zipper carry case. It works with anything that has a headphone jack, no pairing, no battery, no charging.
• Jiunai Open Ear — biggest trade-off: it is wired, so you are tethered to your device, and its "open ear" design means sound isolation is limited by design. If you want to block out a noisy plane cabin completely, that is not what this is built for.
• ZUPVIY Headphones — biggest strength: a 2.4GHz wireless TV setup with a transmitter, up to 40 hours of playtime, and a claimed low-latency link that the spec sheet says is significantly faster than standard Bluetooth.
• ZUPVIY Headphones — biggest trade-off: it is a wireless system, not a wired headphone. There is no headphone jack at all, so it cannot plug into a 3.5mm port directly — it receives audio through its transmitter or over Bluetooth, and it costs you a charging routine.
• Who each pick is for: Jiunai for runners, gym-goers, commuters and anyone with a 3.5mm jack who wants zero charging hassle. ZUPVIY for TV and movie watchers, especially seniors, who want wireless listening without disturbing the household.
The Jiunai Open Ear is a corded earphone first and foremost. Its connector is a 3.5mm headphone jack with 90° right-angled buds, and that right-angle plug matters more than it sounds — it sits flatter against a phone or player in your pocket, which reduces the strain on the cable right where cheap earbuds usually fail. The bud itself is angled at 90° too, so it tucks toward the ear canal instead of sticking straight out.
In my opinion, this is the pick for people whose devices still have a headphone jack and who are tired of charging yet another gadget. The in-line button control and microphone make it workable for calls and online meetings, and the included zipper case, replacement ear tips and 3-month warranty round out a package aimed at daily, slightly rough use.
Who should skip it? Anyone who wants total isolation, or anyone who has already moved to a phone with no headphone jack and no adapter. The open-ear design deliberately lets surrounding sound in — that is the point for a runner who needs to hear traffic, but it is the wrong tool for blocking out a noisy office or a plane engine.
ZUPVIY Headphones: Who It's For
The ZUPVIY Headphones are a different animal entirely. This is a wireless over-ear system built around TV watching, and the box includes both the headphones and a transmitter. The transmitter accepts digital optical, 3.5mm AUX and RCA inputs, and ZUPVIY includes separate RCA and 3.5mm cables so you are not hunting for adapters before your first movie night. That three-input spread is what makes it flexible — it can hang off a TV, an AV receiver or a PC without a dongle chain.
The wireless side runs on 2.4GHz RF for the TV link, with a stated range of up to 295 feet, and the headphones also work independently with a phone over Bluetooth 5.0. The latency claim is the headline: ZUPVIY describes the 2.4GHz link as significantly faster than standard Bluetooth and cites 200ms as the typical Bluetooth figure it is beating. If lip-sync drift has ever ruined a film for you, that specification is the one to care about. Battery life is rated at up to 40 hours per charge, which covers a long weekend of viewing without a trip to the charger.
Comfort is clearly aimed at long sessions: over-ear cups with protein leather and memory foam, plus a headphone stand included for storage. ZUPVIY lists the age range as seniors, and the design choices line up with that — a one-to-one transmitter pairing is far less fiddly than juggling Bluetooth menus, and the over-ear fit does not press into the ear canal the way buds do.
Who should skip it? Anyone who specifically needs a wired 3.5mm headphone. There is no headphone jack on this model at all. If your goal is plugging directly into a handheld player, an old iPod or a airplane seat socket, this is not that product.
Side-by-Side: Which Should You Choose?
• Best for running, gym and cycling → Jiunai Open Ear. The 15° adjustable ear hooks, cord clip and open-ear awareness are all built for movement.
• Best for TV and movie watching → ZUPVIY Headphones. The included transmitter, optical/RCA/AUX inputs and 295ft range exist for exactly this.
• Best for battery life → ZUPVIY Headphones. Up to 40 hours per charge, against a wired earbud that never needs charging at all — different kinds of convenience, but ZUPVIY wins on raw runtime.
• Best for low-latency audio sync → ZUPVIY Headphones. The 2.4GHz link is specifically pitched as faster than standard Bluetooth.
• Best for long-wear comfort → ZUPVIY Headphones for stationary sessions. Protein leather and memory foam over-ear cups versus an open-ear bud that relies on hooks and light contact.
• Best for zero charging and zero pairing → Jiunai Open Ear. Plug in and press play. Nothing to top up, nothing to sync.
• Best for hearing your surroundings → Jiunai Open Ear. The open-ear design lets ambient sound through, which matters on roads and in shared spaces.
If I had to pick one for myself, I would take the Jiunai Open Ear — but only because my use case is movement and a 3.5mm jack, not a living-room TV setup. In my opinion it is the more versatile of the two for everyday carry: no charging, no pairing, a fit that is engineered to stay on, and a price you can check on Amazon via the button on this page. That said, if your actual problem is watching TV late without waking anyone, the ZUPVIY Headphones are the honest answer, and the Jiunai earbuds simply cannot do that job.
how to make aux cable with headphones
You do not need to make anything. A headphone like the Jiunai Open Ear already ends in a 3.5mm plug, which is the standard AUX connector, so it plugs directly into any AUX input on a car stereo, speaker or TV. The ZUPVIY Headphones have no jack at all — they connect through their transmitter's AUX, optical or RCA input instead.
how to use wired headphones without headphone jack
You need an adapter. A 3.5mm-to-USB-C or 3.5mm-to-Lightning dongle lets a wired set like the Jiunai Open Ear work with a phone that dropped its headphone jack. The alternative is a wireless model such as the ZUPVIY Headphones, which connect over Bluetooth 5.0 and need no physical port.
how do i connect my wired headphones to my phone
Plug the 3.5mm plug straight into the phone's headphone jack. If your phone has no jack, use the appropriate adapter, then press play — there is no pairing step. That is the main practical advantage of the Jiunai Open Ear over any wireless option.
Yes. The data sheet lists an in-line control with microphone, and the control type is push button, so calls and online meetings are covered without reaching for your phone. The ZUPVIY Headphones instead let you stay connected to your TV and your phone at the same time, so an incoming call does not interrupt what you are watching.
