• iClever BTH20 — biggest strength: Full over-ear design with genuine Active Noise Cancellation, a 40 mm dynamic driver, and roughly 47.5 hours of average battery life per charge.
• iClever BTH20 — biggest trade-off: It's the heavier, bulkier option at 220 g, and its button controls and over-ear fit are less convenient for sweaty, high-movement exercise.
• TRAUSI Earbuds — biggest strength: Ultra-light earhook earbuds (about 7 g each) with IPX7 water resistance, three earplug sizes, and a charging case that pushes total playtime to 54 hours.
• TRAUSI Earbuds — biggest trade-off: They use Environmental Noise Cancellation (a mic-side feature for calls) rather than active noise cancellation, and each bud only runs about 6 hours before it needs the case.
• Pick iClever BTH20 if you want one pair of headphones for a child, a traveler, or a noise-sensitive listener who needs real ANC and marathon battery life.
• Pick TRAUSI Earbuds if you want secure, sweat-proof buds that stay put during runs, gym sessions, and commutes, and you don't mind recharging via the case.
The BTH20 is a kids-first over-ear headphone that doesn't feel like a toy. The over-ear cups are built from ABS, leather, and POK, with a 40 mm dynamic driver covering a 20Hz–20,000Hz range and 32 ohm impedance — a standard, easy-to-drive setup that plays nicely with phones, tablets, and laptops. What stands out to me is the combination of Active Noise Cancellation and a listed average battery life of about 47.5 hours, recharged in around two hours over USB-C. For a child on a long flight or a car trip, that's the difference between "we forgot the charger" panic and not thinking about charging at all.
Where it falls short: it's not a workout product. At 220 g it's substantial, the over-ear cups trap heat, and there's no water-resistance rating anywhere in the specs. If your main use is running or lifting, this isn't the tool. It's also a single full-size headphone, not something you can slip into a pocket. So the people who should skip it are athletes and anyone who wants something tiny and discreet. Everyone else — parents, travelers, students, and noise-sensitive listeners who want ANC — is squarely in its lane.
TRAUSI Earbuds: Who It's For
The TRAUSI Earbuds (model i27) are the opposite philosophy: tiny, light, and built to move. Each bud is only about 7 g with a soft earhook design, and you get three sizes of silicone earplugs (S/M/L) so you can dial in a secure fit. That earhook is the whole point — it's what keeps them from popping out mid-sprint. Add IPX7 water resistance (sweat, rain, splashes — just not full submersion) and you have a pair that's clearly aimed at runners, gym-goers, and anyone who gets wet and sweaty outdoors.
On the tech side, these run Bluetooth 5.4 with dual-channel transmission and a listed range of up to 15 meters, covering iOS, Android, and Windows, with low-latency audio and support for the usual profiles (HSP, HFP, A2DP, AVRCP). Sound is true wireless stereo, and the mic uses Environmental Noise Cancellation to clean up your voice on calls in noisy places. Be clear on that distinction: ENC helps the person on the other end hear you better — it is not active noise cancellation for you. If you want to mute a plane cabin, these won't do it the way the BTH20 will.
Battery is where the case earns its keep. You get about 6 hours per charge, and the 400mAh charging case stretches that to a claimed 54 hours total. The Type-C case fully charges in about 1.5 hours, and a 10-minute quick charge gives roughly 2 hours of playback — genuinely handy when you're heading out the door. An LED percentage display on the case tells you exactly how much juice is left, which beats guessing. Controls are touch-based (play/pause, skip, volume, voice assistant), and the packaging includes the case, cable, eartips, and manual.
Who should skip these? Anyone who wants big, immersive over-ear sound, real ANC, or a wired fallback. There's no 3.5mm jack here — it's wireless only. And the 90-day warranty is notably shorter than the BTH20's 12 months, so if longevity coverage matters to you, weigh that.
• Best for true noise cancellation → iClever BTH20. Active Noise Cancellation beats the TRAUSI's call-focused Environmental Noise Cancellation for blocking background sound.
• Best for workouts and running → TRAUSI Earbuds. Earhooks, 7 g per bud, and IPX7 sweat/rain resistance are made for movement; the BTH20 has none of that.
• Best for maximum battery per charge → iClever BTH20. ~47.5 hours on one charge versus ~6 hours per TRAUSI bud before you need the case.
• Best for all-day total playtime with a case → TRAUSI Earbuds. The 400mAh case takes you to a claimed 54 hours and the quick charge tops up fast.
• Best for kids and travel with multiple devices → iClever BTH20. Kid–Adults sizing, a detachable 3.5mm cable, plus a protective case covers planes, cars, and tablets.
• Best for discreet, portable everyday listening → TRAUSI Earbuds. They live in a pocket-sized case; the BTH20 is a full-size over-ear pair.
• Best for hands-free touch convenience → TRAUSI Earbuds. Touch controls and voice-assistant activation versus the BTH20's push buttons.
• Best for longer warranty coverage → iClever BTH20. 12 months versus the TRAUSI's 90 days.
My Verdict
If I had to pick one, I'd buy the iClever BTH20 for the majority of buyers — especially parents, travelers, and anyone who wants real Active Noise Cancellation and doesn't want to think about charging for days. That ~47.5-hour battery, the wired fallback, and the 12-month warranty make it the more versatile, lower-stress choice. But I'd recommend the TRAUSI Earbuds without hesitation to runners, gym-goers, and commuters who need lightweight, sweat-proof buds that stay put. Honestly, these barely compete — they solve different problems. Match the product to your routine, not the other way around.
The TRAUSI Earbuds, clearly. Their earhook design, 7 g weight per bud, and IPX7 water resistance are built for sweat and movement. The BTH20 is a 220 g over-ear headphone with no water-resistance rating, so it's a poor fit for hard exercise.
No. TRAUSI uses Environmental Noise Cancellation, which improves how your voice sounds to callers. The BTH20 has true Active Noise Cancellation, which reduces background sound for you. Different features, different purposes.
It depends how you count. The BTH20 gives roughly 47.5 hours on a single charge. Each TRAUSI bud runs about 6 hours, but the 400mAh case extends total playtime to a claimed 54 hours before you need a wall outlet.
I don't quote prices here — check the current price on Amazon before deciding. On specs, "value" depends on your use: the BTH20 wins for kids, travel, and ANC, while the TRAUSI wins for workouts and portability.
