• CASCHO Ear buds — biggest strength: A 650mAh charging case that stretches playback to a claimed 60 hours, plus IPX7 waterproofing and over-ear earhooks that hold firm in sweat and rain.
• CASCHO Ear buds — biggest trade-off: Push-button controls and no active noise cancellation, so it blocks sound only through fit, not electronics.
• GUANDA TECHNOLOGIES CO., LTD Earbuds — biggest strength: A wireless-charging case with dual LED battery readouts, 13mm drivers and dual mics for calls — a slicker, lighter everyday package.
• GUANDA TECHNOLOGIES CO., LTD Earbuds — biggest trade-off: Roughly 40 hours total with about 6 hours per charge, and rounded-tip buds that rely on a good seal rather than earhooks to stay put.
• Pick CASCHO Ear buds if you train hard, sweat a lot, or hate recharging.
• Pick GUANDA Earbuds if you want wireless charging, touch control and a low-key set for commuting, calls and desk work.
The CASCHO set is built around one idea: keep going. Each bud runs about 10 hours, and the case adds five more full charges for a claimed 60 hours total. The case carries a digital display broken into quarters — each grid representing 25% — plus separate left/right indicators, so you always know what's left before you leave the house. A full charge takes about an hour.
Sound comes from a 14.5mm graphene diaphragm, which the specs frame around strong bass with a natural handoff to mids and highs. There's a built-in mic for calls, and Bluetooth 5.3 handles pairing: open the lid and it reconnects to your last device, close it and it disconnects.
Buy it if you're a runner, gym regular or outdoor worker who wants long battery, a locked-in fit and buttons that work when wet. Skip it if you want active noise cancellation — this set has none, and quiet depends entirely on getting a good eartip seal — or if you'd rather tap than press, or if standard rounded buds are simply more comfortable for your ears than hooks.
GUANDA TECHNOLOGIES CO., LTD Earbuds: Who It's For
The GUANDA pair is the more polished daily driver. It runs roughly 6 hours per bud, about 40 hours with the case, and charges fully in around 2 hours. The headline convenience is wireless charging — drop the case on a pad and forget the cable. A dual LED display keeps battery levels visible.
Audio uses 13mm double-layer diaphragm drivers tuned for bright treble, solid bass and clear mids, with dual microphones for calls. That second mic matters: it's aimed at picking up your voice cleanly so conversations don't sound like you're talking into a tin can. Bluetooth 5.3 handles pairing, and a hall switch means the buds reconnect the moment you open the case.
Control is touch-based — one tap for play/pause and calls, two taps to skip tracks, with volume and voice assistant also on board. The shape is rounded tips with an ergonomic seal, and three pairs of eartips are included so you can dial in fit. That seal is doing double duty: it improves bass and blocks outside noise by isolation rather than electronics. Build is ABS plastic in black; weight is around 90g for the set.
Buy it if you want a light, comfortable all-rounder for commuting, calls, TV, laptop and travel, and you value wireless charging and touch controls. Skip it if you need maximum runtime between charges, want earhooks for sprinting or heavy lifting, or know that you fumble touch controls with sweaty hands.
• Best for battery life → CASCHO Ear buds. A claimed 60 hours total versus roughly 40 on the GUANDA set.
• Best for workout security → CASCHO Ear buds. Over-ear hooks with non-slip tips are far harder to shake loose than rounded-tip buds.
• Best for water and sweat → CASCHO Ear buds. IPX7 waterproofing is a step beyond the GUANDA's sweatproof-only framing.
• Best for charging convenience → GUANDA Earbuds. Wireless charging means no cable hunting.
• Best for calls → GUANDA Earbuds. Dual microphones versus a single built-in mic.
• Best for touch-free control → GUANDA Earbuds. Tap gestures are quicker for quick skips; CASCHO's buttons are better with gloves or wet hands.
• Best for all-day comfort → GUANDA Earbuds. Lighter build, rounded tips and three eartip sizes suit long, low-intensity wear.
• Best for sharing or one-bud use → CASCHO Ear buds. Stereo/mono switching is built in.
In my opinion, I'd buy the CASCHO Ear buds — but only if your life involves movement. The combination of IPX7 waterproofing, non-slip earhooks and a claimed 60 hours of playback is exactly what makes a training pair useful, and the physical buttons are a genuine advantage when your hands aren't dry. If you're mostly at a desk, on calls, or you just want to drop a case on a charging pad at night, I'd take the GUANDA Earbuds instead — lighter, touch-controlled, with dual mics and wireless charging. Decide by your routine, not by the spec sheet's biggest number.
Yes, based on the specs. CASCHO claims up to 60 hours total from a 650mAh case, with about 10 hours per bud. GUANDA claims about 6 hours per bud and 40 hours total. Real numbers depend on volume and usage.
No. GUANDA lists sound isolation, meaning the seal from the eartips blocks outside noise — there's no active noise cancellation. CASCHO is the same: no ANC, isolation only. A good eartip fit matters on both.
No. They're IPX7 waterproof for sweat and rain, but the manufacturer specifically says not to swim or bathe in them.
CASCHO, in my opinion. The over-ear hooks and non-slip tips are designed to stay put during strenuous exercise, and the higher waterproof rating handles heavy sweat better than a rounded-tip design.
