How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a familiar, wired-backup-capable over-ear headphone for work, study and long desk sessions, choose iJoy Over-Ear; if you need all-day open-ear awareness for running, gym and commutes, choose TEDELON Open Ear Earbuds. That's the short version. The longer version comes down to one question: do you want your ears sealed off from the world, or do you want them open to it while music plays alongside?
• iJoy Over-Ear — biggest strength: over-ear cups with passive noise cancellation, a 3.5 mm jack and an AUX cable in the box, so you're never fully dependent on Bluetooth or a charged battery.
• iJoy Over-Ear — biggest trade-off: 10 hours of playtime and a 2-hour charge, with no water-resistance rating listed — this is a desk and commute headphone, not a sweat-soaked gym one.
• TEDELON Open Ear Earbuds — biggest strength: 50 hours of battery life, IPX6 water resistance and an open-ear hook design that keeps you aware of traffic and surroundings.
• TEDELON Open Ear Earbuds — biggest trade-off: open-ear means no passive isolation at all, and there's no wired fallback if the battery runs dry.
• Choose iJoy Over-Ear if you want immersion, a mic for calls and a backup wire for zero-battery emergencies.
• Choose TEDELON Open Ear Earbuds if you want maximum runtime, sweat resistance and your ears left open to the world.
The iJoy Ultra is a classic over-ear Bluetooth headphone built around the idea that your ears should be covered. The cups are over-ear with rounded tips, the enclosure is plastic, and the finish here is silver. Inside sits a dynamic driver covering a 20 Hz to 20,000 Hz frequency range at 32 ohm impedance — the full audible span, which is what you'd expect from a general-purpose listening headphone rather than a bass-only novelty.
What makes it genuinely practical is the redundancy. Bluetooth 5 gives you a 10-meter range, and there's a mic for calls, so it works fine as a wireless headset for meetings and classes. But there's also a 3.5 mm jack and an AUX cable in the box. If the battery dies mid-commute, or you want to plug into a laptop, airplane seat or audio interface without pairing anything, you just plug in. Charging is USB-C and takes about 2 hours for roughly 10 hours of playback. Controls are touch-based with volume control, and noise control is passive — meaning the cups physically block sound rather than cancelling it electronically.
TEDELON Open Ear Earbuds: Who It's For
The TEDELON F9 is the opposite philosophy. Nothing goes inside your ear canal. Each earbud hangs on an adjustable ear hook and fires sound toward your ear using directional transmission, which the design uses to limit sound leakage while leaving your ear canal open. The claimed result is that you hear your music and the world at the same time — no stuffiness, no sealed-in pressure.
The headline number is battery life: up to 50 hours, with a wireless charging case in the box alongside the two earbuds, a charging cable and a manual. That's a different category of runtime from the iJoy's 10 hours. It runs Bluetooth 5.4, which the manufacturer says pairs faster and holds a more stable connection in crowded Bluetooth environments than earlier versions. Audio comes from 16.2 mm dynamic drivers — notably large for earbuds — and there's AI Clear Call noise-cancelling that filters background noise on calls, whether that's a subway, a street or a gym. Touch controls handle music and calls, and the earbuds auto-connect to your phone when you lift them out of the case.
Durability is where it separates itself further: IPX6 water resistance means sweat and sudden rain aren't a concern, and the non-in-ear design keeps your ear canal from getting hot and blocked. Who should buy it: runners, gym-goers, cyclists, delivery riders, warehouse workers — anyone who needs situational awareness as a feature, not an afterthought. Who should skip it: people who want to disappear into an album on a plane or block out a noisy open-plan office. Open-ear gives you almost no isolation. It's the point of the design, but it's also the limitation.
Side-by-Side: Which Should You Choose?
• Best for battery life → TEDELON Open Ear Earbuds. Up to 50 hours with a charging case versus about 10 hours on the iJoy.
• Best for running, gym and sweaty workouts → TEDELON Open Ear Earbuds. IPX6 water resistance and secure ear hooks are built for exactly this.
• Best for work, study and long desk sessions → iJoy Over-Ear. Full-size cups, a mic and touch volume control suit hours of seated listening.
• Best for awareness and safety outdoors → TEDELON Open Ear Earbuds. Directional open-ear audio keeps traffic and conversations audible.
• Best for wired fallback and plug-in flexibility → iJoy Over-Ear. The 3.5 mm jack and included AUX cable mean you're never stranded by a dead battery.
• Best for call clarity in noisy places → TEDELON Open Ear Earbuds. AI Clear Call filtering is designed to isolate your voice from background noise.
• Best for a single headphone that does a bit of everything → iJoy Over-Ear. Wireless, wired, mic and over-ear comfort cover more situations in one device.
In my opinion, the right pick depends entirely on where you'll wear them most. If I were buying for an office, a dorm room, a library or a long train ride, I'd take the iJoy Over-Ear — the sealed cups, the mic, the 3.5 mm backup and the plug-in-when-dead flexibility make it the more versatile everyday headphone. If I were buying for running, cycling, the gym or any job where I need to hear what's happening around me, I'd take the TEDELON Open Ear Earbuds without hesitation: 50 hours, IPX6 and an open-ear hook design are purpose-built for movement. One is immersion; the other is awareness. Pick the one that matches your day.
