How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the more feature-rich everyday earbuds with adaptive noise cancelling and a smart case dial, choose CMF BY NOTHING Buds Pro 2; if you need maximum battery life and true IPX8 sweat-and-water protection for hard training, choose Ordtop Sport.
• CMF BY NOTHING Buds Pro 2 — biggest strength: 50dB adaptive hybrid ANC, Dirac-tuned dual drivers (11mm bass + 6mm tweeter) with LDAC, and a smart charging case dial for volume, tracks and noise modes.
• CMF BY NOTHING Buds Pro 2 — biggest trade-off: IP55 only (splash and rinse resistant, not swim-proof), and 43 hours total battery is less than the Ordtop's.
• Ordtop Sport — biggest strength: 70 hours total playtime, IPX8 waterproofing, and a 45° tilt-angle earhook design built to stay put during running and gym work.
• Ordtop Sport — biggest trade-off: Passive noise cancellation only, no ANC, and a slightly shorter single-charge runtime of 14 hours versus the CMF's 10-hour figure — but the Ordtop's total is far larger.
• Pick CMF BY NOTHING Buds Pro 2 if you want active noise cancelling, hi-res audio and a smarter control experience for commuting, working and casual listening.
• Pick Ordtop Sport if you sweat heavily, run outdoors, or want a secure fit and a battery that simply refuses to quit.
The CMF BY NOTHING Buds Pro 2 is the more "tech-forward" pair in this comparison. Its headline feature is 50dB adaptive hybrid ANC, which automatically compensates for leakage between the earbud and your ear canal — that's the kind of detail that matters if you wear buds loosely or move around a lot. There's also a transparency mode with smart ambient sound recognition, so you can stay aware of traffic or announcements without pulling the buds out. On the audio side, it uses a dual-driver setup: an 11mm ultra-bass driver plus a 6mm tweeter, tuned with Dirac and supporting LDAC lossless transmission. In my opinion, that combination is aimed squarely at people who care about sound detail, not just volume.
Who should buy it: commuters, remote workers, gamers and anyone who wants active noise cancelling plus higher-resolution audio in a compact case. Who should skip it: if your priority is surviving repeated soaking sweat sessions or you want the longest possible total battery, the Ordtop is the better fit.
Ordtop Sport: Who It's For
The Ordtop Sport is unapologetically built for movement. The spec that jumps out is IPX8 — a nano-coating on the surface that resists water and sweat penetration, which is a step beyond the CMF's IP55. Combined with liquid silicone ear tips and a 45° tilt-angle earhook design, the goal here is a dual-lock fit that doesn't shift when you run, lift or do burpees. If you've ever had a bud pop out mid-sprint, this is the design philosophy you want.
Battery is the other big story. A single charge gives 14 hours, and the USB-C charging case pushes that to 70 hours total. A 15-minute top-up delivers 2 hours of listening, and an LED display shows real-time battery status so you're never guessing. Bluetooth 5.4 is the newer version here, with faster connection speeds and improved anti-interference — Ordtop claims it holds signal through walls and doors, and the 15-meter range is longer than the CMF's 10 meters. Sound comes from a single 14.2mm dynamic driver with a sound guide architecture for low-frequency rebound, and 4 ENC microphones work to reject background noise on calls.
Here's the honest trade-off: the Ordtop uses passive noise cancellation only. There's no active ANC, so it won't silence a plane cabin or an open-plan office the way the CMF will. Controls are button-based (play/pause, track skip, volume, calls, voice assistant), which many people actually prefer during workouts because sweaty taps on touch controls are unreliable. The Pure Rose Gold finish and 35g weight keep it light.
Side-by-Side: Which Should You Choose?
• Best for active noise cancelling → CMF BY NOTHING Buds Pro 2. 50dB adaptive hybrid ANC versus the Ordtop's passive-only approach.
• Best for battery life → Ordtop Sport. 70 hours total and 14 hours per charge beats the CMF's 43 hours total and 10 hours per charge.
• Best for water and sweat resistance → Ordtop Sport. IPX8 is a higher protection class than the CMF's IP55.
• Best for sound detail and hi-res audio → CMF BY NOTHING Buds Pro 2. Dual drivers, Dirac tuning and LDAC support are hard to match with a single dynamic driver.
• Best for secure fit during workouts → Ordtop Sport. The 45° tilt-angle earhook and silicone tips are designed for stability; the CMF uses a standard in-ear bud shape.
• Best for calls in noisy places → roughly a tie, leaning CMF. The CMF has 6 mics with Clear Voice Technology 3.0; the Ordtop has 4 ENC mics. Both are built for voice clarity, but the CMF's mic count is higher.
• Best for gaming and latency → CMF BY NOTHING Buds Pro 2. 120ms low latency and Bluetooth 5.3 multipoint give it the edge.
• Best for quick top-ups → Ordtop Sport. A 15-minute USB-C charge yields 2 hours versus the CMF's 10 minutes for 3 hours — both fast, but the Ordtop's larger battery makes it more forgiving on long days.
My Verdict
For casual jogging, yes — the CMF's IP55 and ambient sound mode are fine. For heavy sweat or rain, the Ordtop's IPX8 and earhook fit are the safer bet.
It has passive noise cancellation only, plus 4 ENC mics for calls. There's no active ANC, so it won't block engine noise the way the CMF's 50dB hybrid ANC does.
The Ordtop Sport wins clearly: 70 hours total versus 43 hours, and 14 hours per charge versus 10. The CMF's 10-minute fast charge does give 3 hours, though.
No. It's rated IP55, which covers sweat and a quick rinse, not submersion. The Ordtop's IPX8 is the more water-resistant of the two, but neither is marketed as a swim-specific earbud.
