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, over-ear headphone with marathon battery life and a wired fallback, choose iKF R2; if you need hybrid active noise cancellation and a removable boom mic for calls on the move, choose ONANOFF Fokus+ Hybrid ANC.
• iKF R2 biggest strength: A 40mm dynamic driver, 60 hours of playtime, Bluetooth 5.4 multipoint, and a 3.5mm wired option — a lot of everyday flexibility in one retro package.
• iKF R2 biggest trade-off: Its noise control is Environmental Noise Cancellation (ENC), which is aimed at cleaning up your voice on calls rather than actively silencing the world around you.
• ONANOFF Fokus+ biggest strength: True hybrid active noise cancellation, 50 hours of battery, a removable boom mic, and a wireless charging stand that doubles as storage.
• ONANOFF Fokus+ biggest trade-off: It uses Bluetooth 5 and relies on an on-ear fit, and its calling setup is more specialized — you're buying it for the mic and the ANC, not for style or gaming latency.
• Pick the iKF R2 if you want one headphone for music, movies, gaming, and commuting with a vintage look.
• Pick the ONANOFF Fokus+ if your priority is blocking out background noise and sounding clear on work calls.
The iKF R2 is built around a clear idea: take a vintage 80s/90s silhouette and load it with current specs. You get metal accents and litchi-textured leather in a brown finish, a steel strip and leather headband, and over-ear cushions made from protein skin and zero-pressure sponge. That combination matters if you wear headphones for hours — the design is explicitly aimed at a pressure-free fit, and the over-ear cup style spreads contact around your ear rather than pressing on it.
Inside, a 40mm NdFeB dynamic driver covers a 20Hz–20,000Hz range at 32 ohm impedance. In practice that's a balanced tuning meant to handle music, movies, and general listening without leaning hard in one direction. Bluetooth 5.4 supports simultaneous connection to two devices, so you can jump between a laptop and a phone without re-pairing. Battery life is rated at 60 hours with a 2-hour charge time, which is the kind of number that lets you stop thinking about charging for days at a time.
Who should buy it: anyone who wants one retro-looking over-ear pair for commuting, work, travel, and casual gaming, and who values long battery life and a wired backup over active noise cancellation. Who should skip it: if your main problem is airplane engine drone or a noisy open office, ENC won't do what hybrid ANC does — it's there for call clarity, not for silencing your surroundings.
ONANOFF Fokus+ Hybrid ANC: Who It's For
The ONANOFF Fokus+ is a work-first headset. Its headline feature is hybrid active noise cancellation, which uses microphones inside and outside the ear cup to reduce the noise around you. That's a different job from ENC: instead of only sharpening your voice on a call, it lowers what you hear — which is what you want for concentration, clearer conversations, and a cleaner music listening experience in a loud room.
The calling setup is the second clue about who this is for. There's a removable boom mic, so you can position the microphone near your mouth for work calls and meetings, then take it off when you just want to listen to music. Multipoint Bluetooth keeps it connected to more than one device, which suits the person who spends the day switching between a laptop and a phone. Battery life is rated at 50 hours, and the package includes a wireless charging stand — that stand is part of the "built-in media" listing, which tells you ONANOFF intends this to live on a desk, not in a bag.
The design leans practical rather than decorative: a Midnight Blue plastic enclosure, an on-ear fit, touch controls, Bluetooth 5, and a 3.5mm jack for wired listening. The listed weight is 1.16 kg, which is noticeably heavier than the iKF R2's 0.32 kg — that figure almost certainly includes the stand and accessories rather than the headset alone, but it's a fair signal that this is a desk-and-travel kit rather than a featherweight pair you forget you're carrying.
Who should buy it: remote and hybrid workers, frequent flyers, and anyone who takes a lot of calls and needs the room to go quiet. Who should skip it: if you mainly want a stylish everyday headphone for music and gaming, you'd be paying for ANC and a boom mic you won't use, and you'd give up the R2's longer battery rating and lower-latency game mode.
Side-by-Side: Which Should You Choose?
• Best for blocking out noise → ONANOFF Fokus+. Hybrid ANC actively reduces ambient sound; the iKF R2's ENC is a voice-focused feature.
• Best for calls and meetings → ONANOFF Fokus+. A removable boom mic puts the microphone where it belongs for voice.
• Best for gaming → iKF R2. The 35ms ultra-low latency mode is built for audio that matches on-screen action.
• Best for commuting and travel → split decision. The R2 wins on weight and battery; the Fokus+ wins if you're flying and want engine noise pushed down.
• Best for style → iKF R2. Metal accents, litchi-textured leather, and a brown retro finish versus a plain Midnight Blue plastic shell.
• Best for desk setup → ONANOFF Fokus+. The wireless charging stand keeps it topped up and out of the way.
• Best for wired backup → iKF R2. The included 3.5mm AUX cable keeps it usable when the battery is empty.
• Best for lighter, all-day wear → iKF R2. 0.32 kg with an over-ear, pressure-free design and a leather headband.
• Best for multi-device switching → iKF R2. Bluetooth 5.4 with simultaneous two-device connection (the Fokus+ also offers multipoint, but on Bluetooth 5).
In my opinion, the iKF R2 is the better buy for most people. It covers more ground — music, movies, calls, gaming, wired listening — with 60 hours of battery, Bluetooth 5.4 multipoint, and a design you'll actually enjoy wearing. I'd only steer you to the ONANOFF Fokus+ if noise cancellation and a boom mic are the whole point of the purchase, because that's what it does better and what you're paying for. Buy the R2 for everyday life; buy the Fokus+ if your day is calls in noisy rooms. Either way, check the current price on Amazon before you decide, since that's the one thing that can flip this call.
The ONANOFF Fokus+ is better. It uses hybrid active noise cancellation designed to reduce the noise around you. The iKF R2 uses ENC, which targets ambient noise for clearer voice calls rather than actively silencing your environment.
Yes. It includes a 3.5mm AUX cable, so you can plug in and keep listening wired. That's useful when the battery is drained or when you're on a device without Bluetooth. The ONANOFF Fokus+ also has a 3.5mm jack.
The iKF R2 is rated for 60 hours of playtime with a 2-hour charge time. The ONANOFF Fokus+ is rated for 50 hours. Both are long enough to get through a week of commuting or a long trip without daily charging.
The ONANOFF Fokus+ is the more purpose-built option, thanks to its removable boom mic and hybrid ANC. The iKF R2 still handles calls well with ENC and dual-device Bluetooth, but it doesn't put a microphone in front of your mouth.
