How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a retro-styled, featherweight on-ear pair with a huge 60-hour battery, app-based EQ and dual-device switching, choose iKF R1; if you need real hybrid active noise cancellation, over-ear memory-foam comfort and 40 mm drivers for Hi-Fi sound, choose Ulacici Active Noise Cancelling.
• iKF R1 — biggest strength: up to 60 hours of playtime, 38 ms low-latency mode, multipoint pairing for two devices, and an app with EQ customization, all in a lightweight retro on-ear design in Pink.
• iKF R1 — biggest trade-off: no noise cancellation at all, and it is on-ear rather than over-ear, so it blocks less outside sound.
• Ulacici Active Noise Cancelling — biggest strength: hybrid ANC with four microphones that cuts ambient noise by up to 90%, plus 40 mm dynamic drivers in an over-ear, memory-foam and protein-leather build.
• Ulacici Active Noise Cancelling — biggest trade-off: ANC drains battery (about 40 hours with it on instead of 60), it is heavier and bulkier than the on-ear iKF, and the stated warranty is shorter.
• Who each is for: pick the iKF R1 if you want style, long battery life and everyday wireless convenience; pick the Ulacici if quiet is the whole point of your purchase.
The iKF R1 is a lifestyle headphone first and a listening tool second, and I mean that as a compliment. The 30 mm dynamic drivers cover a 20 Hz – 20,000 Hz range at 32 ohms, which is a sensible everyday tuning for pop, podcasts and playlists on the move. What really separates it is the combination of a 60-hour battery and a 2-hour charge time: you can genuinely leave the house for a week and not think about the cable. Bluetooth 5.3 with a 10-meter range keeps the connection stable around an apartment, and the 38 ms low-latency figure is the number gamers and video watchers should care about, because it is the spec that decides whether audio drifts behind the picture.
That last point defines who should skip it. If your commute is a noisy train, an open-plan office or a plane, the iKF R1 gives you music, not silence. Buy it if you want a light, stylish, long-lasting on-ear pair with app tuning and gaming-friendly latency. Skip it if cancellation is non-negotiable.
Ulacici Active Noise Cancelling: Who It's For
The Ulacici is built around one job: making the world quieter. Its hybrid ANC uses four microphones and digital processing to reduce ambient noise by up to 90%, which is aimed squarely at city traffic, engine drone and the general hum of a crowded space. The over-ear design reinforces that physically — memory foam and skin-friendly protein leather seal around the ear, which helps block sound passively before the electronics even kick in. If you have ever tried to work on a plane with on-ear headphones, you already know why this matters.
Sound hardware is a step up on paper too. The 40 mm dynamic drivers are larger than the iKF's 30 mm units, and the claim here is Hi-Fi audio with detail from deep bass to crisp highs, plus lossless wireless audio when paired with Android devices. Battery life is 60 hours, dropping to about 40 hours with ANC switched on — still a long stretch, and the fast-charge claim of 5 minutes for roughly 4 hours of playback is the kind of thing that saves you on a rushed morning. The rotatable, foldable structure makes the over-ear frame easier to pack, and there is a 3.5 mm jack in addition to Bluetooth, so you can keep listening on a wired connection if you want.
The trade-offs are honest ones. It is bigger and heavier than the iKF, so it is less of a "throw it in a pocket" headphone. Its stated warranty period is shorter. And with ANC engaged you are giving up a third of the battery. Buy it if quiet, comfort and fuller sound are what you are shopping for. Skip it if you want something ultra-light, retro and app-customizable.
• Best for noise cancellation → Ulacici Active Noise Cancelling. Up to 90% ambient noise reduction with four ANC mics; the iKF R1 has no noise control at all.
• Best for battery life → iKF R1. 60 hours regardless of mode, versus 60 hours that falls to roughly 40 with ANC on.
• Best for long-wear comfort and isolation → Ulacici. Over-ear memory foam and protein leather; the iKF is on-ear and lets more sound in.
• Best for gaming and video → iKF R1. The 38 ms low-latency figure is the relevant spec here.
• Best for switching between phone and laptop → iKF R1. Multipoint keeps two devices connected at once.
• Best for sound tuning to taste → iKF R1. The iKF app offers EQ presets and saveable custom profiles.
• Best for wired backup → Ulacici. It has a 3.5 mm jack; the iKF R1 is Bluetooth-only.
• Best for style and portability → iKF R1. Retro metal-look finish, Pink colorway, lightweight on-ear build.
In my opinion, the right pick depends entirely on one question: do you need silence? If yes, buy the Ulacici Active Noise Cancelling — the hybrid ANC, over-ear seal and 40 mm drivers are built for commuting, flights and noisy rooms, and the 40-hour ANC battery is plenty. If no, I would buy the iKF R1: 60 hours of playtime, multipoint, app EQ and 38 ms latency in a light retro shell is a more enjoyable everyday headphone. I would only choose the Ulacici for quiet, and the iKF for everything else.
FAQ
No — 60 hours is the figure without ANC. With active noise cancellation running you get up to about 40 hours of continuous listening, and a 5-minute fast charge adds roughly 4 hours.
Yes. It has a 38 ms low-latency mode for games and video, a built-in mic for hands-free calls, and multipoint so your phone and laptop stay connected at the same time.
Both are value-focused designs, so the deciding factor is features rather than anything I would quote here. Check the current price on Amazon for each, then match the spec list above to your commute — cancellation versus battery and portability.
