• Poounur strength: silicone ear hooks plus three sizes of ear tips (S, M, L) and an IP7 waterproof body — the fit is built for hard workouts that would shake ordinary in-ears loose.
• Poounur trade-off: it seals your ear canal, so you lose awareness of what's around you, and the manufacturer notes call time drops to roughly 3–4 hours versus the 8–10 hours of music playback.
• MAcnas strength: the ear-clip open design keeps your ear canal clear, so you hear approaching cars, cyclists and people while music plays — plus a claimed 50-hour total with the case.
• MAcnas trade-off: no noise control at all, and open-ear buds sit outside the canal, so bass depth and isolation are naturally limited compared with a sealed in-ear fit.
• Pick Poounur if you train in a gym, lift, or run on quiet routes and want punchy sound with a locked-in fit.
• Pick MAcnas if you run or ride near traffic, or you simply dislike things plugging your ears for hours.
The Poounur Earbuds (model H9) are a sport-focused true wireless set built around fit security. Each bud weighs just 4.2 g and uses flexible silicone ear hooks plus an ergonomic shell, so the design intent is clear: keep the bud in place during running, lifting and other movement-heavy sessions. Three pairs of ear tips in small, medium and large let you dial in the seal. The buds are purple, and the charging case matches.
On the audio side, Poounur lists a 13 mm dynamic driver in the marketing copy and a 10 mm driver in the spec sheet — the two figures don't agree, so I'd treat the exact driver size as uncertain and focus on what's consistent: a dynamic driver tuned for punchy bass and a full midrange, with a 20 Hz–20,000 Hz frequency range and 32 ohm impedance. There's ENC noise cancelling for calls, and the controls are touch-based with active noise cancellation listed under noise control. Bluetooth 5.3 handles the connection, with support for HSP, HFP, A2DP and AVRCP, and the sheet lists a 10 m range (the feature copy claims up to 15 m — again, the two don't match).
Battery is the headline feature. The buds are rated around 10 hours of music per charge, and the 500 mAh case extends total playtime to roughly 50 hours, with a dual LED display showing real-time battery status on the case. A USB-C charge takes about 1.5 hours for the buds and 1.5 hours for the case. The IP7 waterproof rating covers sweat and rain, though the manufacturer advises wiping the metal charging contacts dry after exercise to avoid corrosion.
Buy it if you want a sealed, hook-anchored fit for gym sessions, treadmill runs, and commutes where you'd rather block the world out. Skip it if you need to stay aware of traffic or your surroundings, or if you take long calls — the quoted 3–4 hour call time is a real limitation.
The MAcnas Earbuds Open Ear (model M47) take the opposite approach. Instead of plugging your canal, they clip around the ear and fire sound at it — an air-conduction, open-ear design. The stated purpose is safety and awareness: you keep hearing ambient sound, which matters if you run near roads, share paths with cyclists, or want to hear a training partner. The buds are white, and the charging case comes in black, yellow or white depending on which variant you pick.
The specs are straightforward: Bluetooth 5.3, a 20 Hz–20,000 Hz dynamic driver, 32 ohm impedance and 115 dB sensitivity, which suggests the buds are easy to drive to a loud level. There's no noise control listed at all — that's a deliberate trade-off of the open design, not an oversight. Touch controls handle volume, track changes and calls on either bud, and the case uses a hall switch so the buds reconnect automatically when you open the lid after the first pairing. Range is listed at 10 m. The case is ABS and plastic, weighs 68 g, and measures roughly 2.9 × 1.6 × 1.3 inches — noticeably bulkier than typical pocket cases.
Battery figures are a bit tangled. The spec sheet lists about 6 hours per charge for the buds and a 50-hour total with the case, while the feature copy mentions 5 hours of continuous playback and an extra 40 hours from the case. Either way, it's a long-running setup: 1.5 hours to charge the buds, 2 hours for the 200 mAh case. The case has a mirrored dual LED display for power levels. Warranty is listed at 30 days, which is shorter than Poounur's "yes" (a warranty is included but the length isn't specified).
Buy it if situational awareness is your priority — outdoor running, cycling, walking in the city, or wearing buds for hours without canal fatigue. Skip it if you want deep isolation, heavy bass slam, or you mostly listen in loud environments like a packed train or a noisy gym.
• Best for workout security → Poounur Earbuds. Silicone ear hooks plus three ear-tip sizes are purpose-built to stay put.
• Best for outdoor safety → MAcnas Earbuds Open Ear. The open clip design keeps ambient sound audible, which the manufacturer explicitly frames around hearing vehicles and pedestrians.
• Best for bass and sealed listening → Poounur Earbuds. A sealed in-ear fit with a bass-forward dynamic driver will always outperform an open-ear design on low-end depth.
• Best for all-day comfort → MAcnas Earbuds Open Ear. Nothing enters your ear canal, so there's no pressure or "plugged" feeling over long sessions.
• Best for total battery with the case → MAcnas Earbuds Open Ear on the numbers (up to 50 hours claimed, versus roughly 50 hours for Poounur — effectively a tie, but MAcnas quotes the higher single-charge figure in its feature copy).
• Best for long calls → neither, strictly speaking. Poounur quotes only 3–4 hours of call time; MAcnas emphasizes call clarity but doesn't break out call battery. If calls dominate your day, plan for charging.
• Best for water and sweat resistance → Poounur Earbuds. IP7 is an explicit rating; MAcnas doesn't list one.
• Best for awareness plus music at the same time → MAcnas Earbuds Open Ear. This is the one job the open design does that Poounur fundamentally can't.
In my opinion, the choice comes down to one question: do you need to hear the world while you listen? If yes, I'd buy the MAcnas Earbuds Open Ear — the clip design, 115 dB sensitivity and long case runtime make it a sensible everyday companion for runners and city walkers. If you want sound that hits harder and a fit that survives burpees, I'd buy the Poounur Earbuds instead; the ear hooks, IP7 rating and bass-tuned driver are better suited to indoor training. I'd only hesitate on Poounur if you take a lot of calls, because that's where its battery rating drops off most.
For awareness, yes. The open ear-clip design lets ambient sound in, which the manufacturer ties directly to hearing vehicles and pedestrians. Poounur seals your canal, so you'll hear less of what's around you.
That's their stated purpose. Flexible silicone ear hooks plus three ear-tip sizes (S, M, L) are designed to keep them seated during running and other movement. The IP7 rating also covers sweat, though you should dry the metal contacts after use.
Poounur, in my opinion. A sealed in-ear fit with a bass-forward dynamic driver will deliver more low-end than an open-ear clip design, which by nature can't isolate or pressurize your ear canal.
Poounur lists active noise cancellation for calls via ENC, which filters environmental noise on the microphone side. MAcnas lists noise control as "none" — it's an open design, so blocking sound isn't part of the plan.
