If you want a lightweight, retro-styled everyday headphone with app-tuned sound and a huge 60-hour battery, choose iKF R1; if you need active noise cancelling, kid-safe volume limiting, and a rugged build for travel, choose iClever BTH20.
• iKF R1 — biggest strength: Bluetooth 5.4, multipoint pairing, a custom EQ app, and up to 60 hours of playtime in a 93 g on-ear frame with a brown retro metal-and-plastic look.
• iKF R1 — biggest trade-off: It only offers passive noise cancellation — no active noise cancelling — and there's no wired jack, so it's wireless-only.
• iClever BTH20 — biggest strength: Active Noise Cancelling (35 hours ANC on, 60 hours off), an 80 dBA volume limit with Sound Refiner, a 3.5 mm AUX cable, and a drop-and-bend-resistant build for kids 3 and up.
• iClever BTH20 — biggest trade-off: It's a heavier over-ear at 220 g, and its kid-focused tuning and light blue color aren't aimed at adult listeners who want a neutral sound.
• Who each pick is for: iKF R1 for adults who want retro style and flexible app control; iClever BTH20 for parents who need safe, durable travel headphones for a child.
The iKF R1 leans hard into a single idea: a vintage-looking on-ear headphone that still behaves like a modern one. The metal-and-plastic enclosure, circular earcups, and brown finish give it a look that stands apart from the glossy plastic most budget headphones share. At 93 g, it's genuinely light, so the adjustable headband and soft cushions are doing less work than they would on a heavier set.
On the tech side, the R1 covers the things a daily listener actually notices. Bluetooth 5.4 with a rated 15-meter range keeps the connection steady, and multipoint lets you jump between a phone and a tablet without repairing. The 30 mm dynamic drivers, 32 ohm impedance, and 20Hz–20,000Hz range are standard on-ear territory — nothing exotic, but the real differentiator is the app, which lets you shape a custom EQ and control playback by touch or button. Battery is the headline: up to 60 hours per charge with a roughly 2-hour top-up.
Who should buy it: anyone who wants a featherweight, stylish headphone for commutes, long flights, and desk work, and who likes the idea of tuning the sound to taste. Who should skip it: if you fly often and want to quiet engine drone, passive noise cancellation won't cut it — and there's no 3.5 mm jack, so you can't fall back to a wired connection.
The iClever BTH20 is built around a different question: how do you make headphones a child can use safely, for hours, without breaking them? The answer shows up in the details. The ABS shell uses materials free of BPA and PVC, with reinforced internals meant to survive drops, bends, and the button wear that typically causes one-sided sound loss. The 90° rotatable earcups and 10-level adjustable headband are sized for kids aged 3 and up, and the large push buttons are easy for small hands.
The safety engineering is the part parents care about most. iClever's Sound Refiner and an 80 dBA volume limit reduce output in the frequency range most vulnerable to hearing damage while keeping the sound balanced — which matters on a plane or in a car where kids tend to crank the volume. Active Noise Cancelling is genuinely useful here: it cuts the ambient roar so your child doesn't need to push volume up to hear a show. Battery runs 60 hours with ANC off and 35 hours with ANC on, and a 10-minute USB-C charge buys about 5 hours. The included 3.5 mm AUX cable also means it works on in-flight entertainment systems with no battery at all.
Who should buy it: parents of young kids who want durable, volume-limited, ANC-equipped travel headphones. Who should skip it: adults who want a neutral sound signature or a subtle-looking set — at 220 g and in light blue, this is clearly a kids' product.
• Best for active noise cancelling → iClever BTH20. It's the only one of the two with ANC; the iKF R1 relies on passive isolation only.
• Best for battery life → effectively a tie, with a caveat. Both hit 60 hours, but the iClever only reaches that with ANC off (35 hours with it on), while the iKF R1's 60 hours is its normal figure.
• Best for hearing safety and kids → iClever BTH20. The 80 dBA limit, Sound Refiner, and age-3-and-up fit are purpose-built; the iKF R1 has none of these.
• Best for lightweight comfort → iKF R1. At 93 g versus 220 g, the R1 is dramatically lighter on the head.
• Best for wired use → iClever BTH20. It has a 3.5 mm jack and ships with an AUX cable; the iKF R1 has no jack at all.
• Best for sound customization → iKF R1. The companion app's custom EQ and touch controls give you tuning the iClever doesn't offer.
• Best for switching between devices → iKF R1. Multipoint connection lets it hold two devices at once.
• Best for surviving rough handling → iClever BTH20. Reinforced structure and impact-resistant materials are specified for drops and bends.
In my opinion, these two barely compete for the same buyer, so the choice is really about who's wearing them. For an adult who wants a light, retro-looking headphone with app-tuned sound and multipoint, I'd pick the iKF R1 — the 93 g build and custom EQ make it a genuinely pleasant all-day set. But if the listener is a child, or you mainly want to kill airplane and road noise, I'd buy the iClever BTH20 without hesitation. Its ANC, 80 dBA limit, and durability engineering are things the R1 simply doesn't attempt.
The iClever BTH20, clearly. It has active noise cancelling, while the iKF R1 only offers passive noise cancellation, which relies on the earcup seal rather than electronics.
Both are rated at 60 hours. The difference is that the iClever drops to 35 hours once you switch ANC on, whereas the iKF R1's 60 hours applies to normal listening.
The iKF R1 isn't designed as a kids' product and has no volume limit or age rating. For a child, the iClever BTH20's 80 dBA cap and Sound Refiner make it the safer choice.
Only the iClever BTH20. It includes a 3.5 mm AUX cable for wired listening, while the iKF R1 has no headphone jack and is wireless-only.
