How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the lightest possible open-ear fit with modern Bluetooth flexibility, choose mifo FiiTii Z Open; if you need an in-ear hook design with a bigger charging case and ENC call clarity, choose Fabater Lightweight Headphone Noise. That's the short version. The longer answer comes down to one question: do you want your ears open to the world, or do you want sound delivered straight into them? Both are built around the idea of staying light on your head, but they get there in completely different ways.
• mifo FiiTii Z Open — biggest strength: a genuinely featherweight open-ear hook at just 5.9g per earbud, with a hook radius under 1mm that's designed to sit alongside glasses without pressure.
• mifo FiiTii Z Open — biggest trade-off: the open-ear shape means no passive isolation, and the spec sheet lists no active noise cancellation at all.
• Fabater Lightweight Headphone Noise — biggest strength: an in-ear hook design that injects sound directly into the ear canal for a private, immersive listen, backed by ENC noise cancelling for calls.
• Fabater Lightweight Headphone Noise — biggest trade-off: the spec sheet gives no weight figure, no battery-hour rating, and no IP water-resistance rating, and lists connectivity as ethernet — a field that simply doesn't match a wireless headphone.
• Who each pick is for: mifo FiiTii Z Open for runners, cyclists, glasses wearers and anyone who wants an open ear; Fabater Lightweight Headphone Noise for desk work, study and commuting where a slim in-ear hook and clear voice pickup matter more.
The FiiTii Z Open is built around one number: 5.9g. mifo states that most open-ear headphones on the market weigh over 10 grams, and the design work here is aimed squarely at that gap — a wire radius under 1mm and an ear hook radius under 1mm, versus the 3mm-plus hooks mifo says are typical elsewhere. If you wear glasses, that thin hook is the detail that matters. A chunky hook and a glasses arm fight for the same real estate behind your ear; a sub-millimetre hook is designed to coexist with it. In my opinion, that alone makes this a serious candidate for anyone who has given up on open-ear buds because of glasses.
Buy it if: you run, cycle or train outdoors, wear glasses, want an open ear for safety and awareness, and value dual-device Bluetooth switching. Skip it if: you want isolation from traffic, gym noise or a loud office — this is an open design with no noise cancellation listed, so background sound gets in.
Fabater Lightweight Headphone Noise: Who It's For
The Fabater is the opposite philosophy in a similar physical format. It's an in-ear hook headset, not open-ear, and the pitch is precise sound delivery — audio injected directly into the ear canal for a private, immersive listen. That's the meaningful difference for buyers: you get more isolation and more perceived bass from an in-ear seal, and your audio stays yours. If you study in a library, work in a shared office, or commute on a bus and don't want your podcast broadcast to the row behind you, an in-ear hook is the smarter shape.
The slimness claim is specific: 8mm wide and 6mm thick. That's a thin profile designed to sit flush and avoid the pressure points that thicker earbuds create over long sessions. Fabater also lists ENC noise cancelling for calls, which targets the same problem the mifo does — making your voice intelligible on the other end — and it's the single most useful feature here if you take a lot of meetings or calls.
Buy it if: you want an in-ear hook for study, desk work, office and commute, you care about voice clarity on calls, and you prefer a thin, low-profile fit. Skip it if: you need confirmed water resistance, a stated playtime figure, or an open-ear design for outdoor awareness.
Side-by-Side: Which Should You Choose?
• Best for the absolute lightest fit → mifo FiiTii Z Open. 5.9g is stated outright; Fabater gives no weight figure at all.
• Best for glasses wearers → mifo FiiTii Z Open. The sub-1mm hook radius is specifically designed to sit next to glasses arms.
• Best for privacy and isolation → Fabater Lightweight Headphone Noise. In-ear delivery keeps sound in your head; the mifo is open by design.
• Best for outdoor sports and sweat → mifo FiiTii Z Open. IPX5 plus ENC wind-noise reduction up to 20 km/h is a clear outdoor brief.
• Best for calls and meetings → a tie, leaning Fabater. Both list ENC, but the in-ear shape blocks more of the room around you.
• Best for battery transparency → mifo FiiTii Z Open. 8 hours per charge and 27 hours with the case are stated; Fabater gives mAh only.
• Best for multi-device workflow → mifo FiiTii Z Open. Bluetooth 5.4 dual-device pairing is spelled out on the spec sheet.
• Best for a slim, low-pressure profile → Fabater Lightweight Headphone Noise. 8mm wide and 6mm thick is a genuinely thin build.
My Verdict
For running, yes — in my opinion. It's rated IPX5 for sweat and light rain, and its ENC is tuned to reduce wind noise up to 20 km/h. The Fabater lists no water-resistance rating, so I wouldn't pick it for sweaty outdoor sessions.
The Fabater Lightweight Headphone Noise. It's an in-ear hook design that injects sound directly into your ear, so you get more isolation and more privacy than the open-ear mifo, which lets the room in by design.
Not in the same sense. Both list ENC, which is call-side noise cancellation for clearer voice pickup. Neither spec sheet lists active noise cancellation for the listener. If you want to block out sound, the Fabater's in-ear seal does more of that work.
The mifo states 8 hours per charge and 27 hours total with the case; the Fabater states 600mAh in the case and 45mAh per earbud without an hour figure. On stated playtime, the mifo is the more concrete answer. For current pricing on either, check the price on Amazon — the page has a button for it.
