How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven, simple over-ear with a long battery and active noise cancellation, choose iJoy ISO; if you need a lightweight, budget-friendly pair with eye-catching LED lights for studying, travel or casual listening, choose LFGKeng Headphones.
• iJoy ISO — biggest strength: Bluetooth 5.0 with a claimed 30 hours of battery life, active noise cancellation, touch controls and a foldable over-ear build.
• iJoy ISO — biggest trade-off: The buttons and touch controls need a bit of learning, and the over-ear fit is bulkier than a lightweight set.
• LFGKeng Headphones — biggest strength: A light 250 g foldable frame with colourful LED lighting, Bluetooth 5.0 and a built-in mic for hands-free calls.
• LFGKeng Headphones — biggest trade-off: It doesn't publish a battery life figure, so long-haul listening is less predictable.
• Who each pick is for: iJoy ISO suits commuters and call-heavy users who want ANC and long playtime; LFGKeng Headphones suit students, kids and casual listeners who want a fun, light, easy-to-carry set.
The iJoy ISO is the more "serious" pair of the two. It runs Bluetooth 5.0 with a quoted range of 33 feet, so you can leave your phone on a desk or kitchen counter and keep listening while you move around the room. The headline number is battery: up to 30 hours of use, with a full charge taking about 2.5 hours. That's the kind of figure that means you can get through a week of commutes or a long stretch of calls without hunting for a cable.
On top of that, it adds active noise cancellation and touch controls. ANC is the feature that separates it from most budget over-ears — it's aimed at dulling the drone of a train, plane or open-plan office so you can hear your audio at lower volumes. The touch panel handles volume, track skipping, calls and power, and there's a built-in mic for hands-free talking.
The fit is over-ear with cushioned cups and a padded headband, and the whole thing folds down for storage. The drivers run a 20Hz–20,000Hz range, which covers the full audible spectrum. There's also a 3.5 mm jack, so you can fall back to a wired connection when you want.
Skip it if: you want the lightest possible set for a kid, or you'd rather have visible, fun lighting than noise cancellation.
LFGKeng Headphones: Who It's For
The LFGKeng Headphones take a different approach. The standout feature is the colourful LED lighting built into both earcups, which pulses with the rhythm of your music. It's a style choice as much as a spec — for a teenager, a dorm room or a gaming desk, that reactive glow is the whole point.
Weight is the other big selling point: 250 g. That's light for an over-ear set, and combined with the foldable design it's genuinely easy to toss in a bag. The cups are plastic, the colour is red and black, and the drivers are dynamic with the same 20Hz–20,000Hz range as the iJoy. Impedance is listed at 32 ohm, which is a fairly standard figure for consumer headphones and means they'll play fine from a phone, laptop or tablet.
Connectivity is Bluetooth 5.0 with a stated range of 10 metres — roughly 33 feet, so effectively the same freedom of movement. There's a built-in mic for hands-free calls, media controls, active noise cancellation and a 3.5 mm jack for wired use. The brand also emphasises customer support, promising a reply within 24 hours if something goes wrong.
The catch is what isn't stated. There's no published battery life figure, so if you're planning eight-hour study sessions or long flights, you can't plan around a number. And while ANC is listed, the focus of the product is clearly the look and the light weight rather than premium noise blocking.
Buy it if: you want a light, affordable, foldable set with LED flair for study, travel, class, the office or casual PC use — and you're happy to charge it regularly.
Skip it if: you need a documented long battery life, or you want the most capable noise cancellation.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → iJoy ISO. Both list ANC, but the iJoy is built around it as a core feature.
• Best for light weight → LFGKeng Headphones. 250 g is easy to carry all day.
• Best for style and fun → LFGKeng Headphones. The reactive LED lighting is a genuine differentiator.
• Best for calls and commuting → iJoy ISO. 30 hours of talk time plus ANC and touch controls.
• Best for students, kids and casual desk use → LFGKeng Headphones. Light, foldable and visually engaging.
• Best for wired fallback → a tie. Both include a 3.5 mm jack.
• Best for people who want a documented spec sheet → iJoy ISO. More of the key numbers are published.
In my opinion, the iJoy ISO is the better buy for most people. It gives you a real battery figure, active noise cancellation and a foldable over-ear design that covers commuting, calls and long listening sessions. The LFGKeng is a fine choice if light weight and LED looks matter more to you than battery certainty — it's the more playful set. But if you want one pair that handles the daily grind without a charging anxiety, I'd take the iJoy ISO. Check the current price on Amazon before you decide, since that gap often settles the argument.
For long trips, yes — the 30-hour battery and ANC make it the more predictable travel companion. The LFGKeng folds smaller and weighs less, so it's easier to pack, but you'll be charging it more often.
Both list active noise cancellation and Bluetooth 5.0. The iJoy ISO treats ANC as a headline feature; on the LFGKeng it's listed alongside the LED lighting and lightweight build, which are the main selling points.
The LFGKeng Headphones are the more natural fit — 250 g, a foldable frame and colourful LED lighting suit a backpack, a dorm desk or a classroom. The iJoy ISO is the better pick for a working adult who needs ANC and battery life.
Yes. Both the iJoy ISO and the LFGKeng Headphones include a 3.5 mm jack, so you can plug in when the battery runs down or when you want zero latency.
