• CASCHO Ear buds — biggest strength: Up to 60 hours of total listening time from the charging case, with a 14.5mm graphene diaphragm and IPX7 waterproofing, all backed by an over-ear hook that stays put during hard workouts.
• CASCHO Ear buds — biggest trade-off: These are true in-ear buds, so they seal off your ear canal and there is no active noise cancelling — you pick the right eartips or the bass and isolation suffer.
• JOYROOM Open Ear Headphones — biggest strength: An open-ear hook design with each bud weighing about 10g and a 16mm driver, so your ear canals stay open and comfortable for hours.
• JOYROOM Open Ear Headphones — biggest trade-off: IPX4 only resists sweat and light rain (not a soaking), and the open design deliberately lets outside sound in — there is no noise cancelling.
• Who each is for: CASCHO suits gym-goers, runners and anyone who wants long battery life and deep bass in a sealed fit. JOYROOM suits commuters, walkers and people who hate the plugged-up feeling of in-ear buds.
The CASCHO BX17 nails the fundamentals that matter for a sports earbud. The headline number is playtime: roughly 10 hours from a single bud, stretching to about 60 hours in total once you factor in the recharges stored in the 650mAh case. That charging case has a digital display showing battery in 25% increments for each side, so you always know how much juice is left before you head out the door. If you train several times a week and hate babysitting a charger, that math matters.
On the audio side, CASCHO uses a 14.5mm graphene diaphragm, which the spec sheet ties to strong bass that flows into the mids and highs. There is a built-in mic for calls, and the 32-ohm impedance and 103dB sensitivity mean these should be easy to drive from a phone. Bluetooth 5.3 handles the connection, with auto-pairing when you lift the lid and auto-disconnect when you drop them back in. The over-ear silicone hooks, with a non-slip finish at the tip, are the real selling point for movement — they are built so the buds stay put even during strenuous exercise.
Buy CASCHO if you want a sealed in-ear fit, deep bass, IPX7 protection against sweat and rain, and the longest battery life of the two. Skip it if you dislike things sitting inside your ear canal, need active noise cancelling (there is none here), or want to stay fully aware of traffic and surroundings. One honest caveat from the maker's own notes: don't swim or bathe in them, and if the sound feels thin, swapping eartips for a tighter seal is the fix.
The JOYROOM OE4 goes the opposite direction. Instead of sealing your ear, it hangs on a hook and leaves the canal completely open, and the brand leans hard into comfort — each bud is about 10g, and the silicone build is meant to let your ears breathe over a full day of wear. If in-ear buds always end up feeling itchy or painful after an hour, that open design is the entire reason to look here.
Battery is strong too, just not quite CASCHO-level: about 12.5 hours from a single charge and up to 50 hours with the charging case, with an LED display to track it. The driver is a 16mm dynamic unit paired with a bass-enhancement algorithm and directional sound transmission, which aims to push audio toward your ear while limiting how much leaks out — so your podcast stays your podcast on a quiet train. Bluetooth 5.4 is the newer standard of the two, and JOYROOM lists a 10-meter range with instant pairing when you pull the buds out.
The trade-offs are real. IPX4 means sweat and light rain are fine, but these are not the pair to dunk or wear in a downpour. And the open design means you hear the world — great for cycling and city walking, less great if you want to block out a noisy gym. There is no active noise cancelling here either.
Buy JOYROOM if comfort and situational awareness top your list, and you want the latest Bluetooth version in a lightweight open-ear format. Skip it if you need maximum sweat-and-rain protection, the deepest possible bass, or any degree of sound isolation.

If I had to pick one, I would buy the CASCHO Ear buds. In my opinion, the combination of up to 60 hours of playtime, IPX7 waterproofing and a non-slip over-ear hook makes it the more versatile pick for anyone whose main use is working out and who wants bass that actually lands. The JOYROOM is the better choice only if comfort and hearing your surroundings matter more to you than isolation and sweat protection. Neither has noise cancelling, so decide based on fit and environment, not on blocking the world out. Check the current price on Amazon before you commit, since that is the one thing that can flip this call.
Both are built for sport, but they differ in approach. CASCHO uses a sealed in-ear fit with non-slip hooks and IPX7 protection, while JOYROOM uses a lighter open-ear hook with IPX4. For heavy sweat, CASCHO has the edge.
No. CASCHO has no active noise cancelling and relies on eartip seal, while JOYROOM openly states its open-ear buds do not feature ANC. JOYROOM lists sound isolation, but the open design still lets ambient noise in by nature.
CASCHO offers up to 60 hours total with about 10 hours per single bud. JOYROOM offers up to 50 hours total with about 12.5 hours per single charge. So CASCHO wins overall, JOYROOM wins per charge.
No. CASCHO carries an IPX7 rating and is fine for sweat and rain, but the manufacturer's own guidance says not to use them while swimming or bathing. JOYROOM's IPX4 is even less suited to being submerged.
