• RCA Earbuds — biggest strength: A proper in-ear sport build. Flexible earhooks, just 7.8g per earbud, three sizes of silicone tips, IPX5 sweat and rain resistance, and a 13mm dynamic driver tuned for deep bass. In my opinion, this is the one built for hard training.
• RCA Earbuds — biggest trade-off: In-ear means you're sealed off from your surroundings, and passive noise cancellation is exactly that — passive. No ambient mode to let traffic or a training partner through.
• CHENRUIDA Open Ear Clip — biggest strength: The open-ear clip format. Nothing goes into your ear canal, so you hear music and the world at the same time. Add Bluetooth 6.0, IPX6 waterproofing, and a charging case with an LED percentage display.
• CHENRUIDA Open Ear Clip — biggest trade-off: Open-ear design trades isolation for awareness, so bass and volume won't hit like a sealed in-ear bud. There's also no published per-earbud weight or charge time per bud to compare against.
• Who each pick is for: Choose RCA Earbuds if you want maximum grip, sweat protection and bass for running, gym and cycling. Choose CHENRUIDA Open Ear Clip if you want all-day comfort, situational awareness, and a case that doubles as a fashion accessory.
RCA's WAVE-40 is a sport-first design, and the spec sheet reads that way. Each earbud weighs only 7.8g and uses a flexible earhook that loops over the ear, so the bud is anchored in two places rather than relying on the ear canal alone. For running, cycling or lifting, that's the difference between a bud that stays put and one you keep re-seating between sets. You also get three sizes of soft silicone tips, which matters more than people think — the seal is what delivers the bass and the passive noise blocking, so a correct fit is doing real work here.
The audio side is straightforward: a 13mm dynamic driver, 16 ohm impedance, and a stated frequency response up to 50 KHz, which is far beyond what any human ear can hear but signals the tuning is aimed at a lively, bass-forward presentation. Bluetooth 5.3 with a 16 ms latency figure and a 10-meter range covers the practical stuff — gym, trail, commute, with audio staying in sync well enough for video and casual gaming. Battery is 6 hours per charge and up to 48 hours with the case, with a 1.5-hour charge time and a 420 mAh case battery that itself recharges in about 2 hours. IPX5 covers sweat, splashes and light rain.
The control scheme is touch plus a physical button, which is a genuinely useful combo when your hands are sweaty — touch gestures alone can be finicky mid-workout. Built-in ENC microphones suppress background noise on calls.
Buy it if you train hard, want a locked-in fit, and want the bass and isolation that come with a sealed in-ear tip. Skip it if you need to hear traffic, your surroundings, or a coach while you listen — an in-ear bud is the wrong tool for that job, and RCA doesn't offer an ambient mode to solve it.
The CHENRUIDA M156 is the opposite philosophy, and it's a smart one for a specific buyer. It's an open-ear clip-on: the bud rests on the outside of your ear and fires sound toward the canal without plugging it. Nothing presses into your ear, so there's no in-ear fatigue after a few hours, and you stay fully aware of traffic, coworkers, or your kids while music plays. For cyclists on open roads, runners on shared paths, and office workers who need to hear a doorbell, this is the design that actually makes sense.
The headline spec is Bluetooth 6.0 — a newer generation than the 5.3 on the RCA pair, promising a faster, more stable link. CHENRUIDA pairs it with a dedicated bass-enhancement driver, a sensible move because open-ear designs typically leak low end. Battery is 5 hours per bud and up to 40 hours total with the case, and the case has an LED display showing exact remaining percentage — small thing, genuinely useful, no more guessing whether you have enough juice for the commute home. IPX6 waterproofing is a notch above IPX5, so sweat, rain and splashes are covered, and the case charges via Type-C in about 1.5 hours.
Then there's the part that makes this product unusual: the detachable pearl resin bead bracelet on the charging case, plus a hidden fold-out mirror. It's a styling choice pitched squarely at women who want their earbuds to look like jewelry rather than tech. The case is white plastic, the fit is open-ear, and controls are touch-based with environmental noise cancellation on calls.
Side-by-Side: Which Should You Choose?
• Best for intense workouts and sweat-heavy training → RCA Earbuds. Earhooks, 7.8g buds, three tip sizes and IPX5 are a purpose-built sport package.
• Best for all-day comfort and no in-ear pressure → CHENRUIDA Open Ear Clip. The clip-on format never enters the ear canal.
• Best for staying aware of your surroundings → CHENRUIDA Open Ear Clip. Open-ear by design; the RCA pair seals you in with passive noise cancellation.
• Best for bass and a sealed, immersive sound → RCA Earbuds. A 13mm dynamic driver plus a proper tip seal is the combination that delivers low end.
• Best connectivity generation → CHENRUIDA Open Ear Clip. Bluetooth 6.0 versus Bluetooth 5.3 on the RCA pair.
• Best battery readout and travel convenience → CHENRUIDA Open Ear Clip. Up to 40 hours total with an LED percentage display on the case.
• Best battery ceiling on paper → RCA Earbuds. Up to 48 hours with the case, plus a stated 1.5-hour charge time.
• Best for a style-forward, giftable design → CHENRUIDA Open Ear Clip. The pearl bracelet and fold-out mirror case are genuinely unusual.
• Best for gym, running and cycling with maximum grip → RCA Earbuds. That's the use case the whole design is organized around.
In my opinion, the RCA Earbuds are the better buy for anyone whose priority is training. The earhook fit, 7.8g per bud, IPX5 rating and 13mm driver all point at one job — staying in your ears and sounding full while you move — and the 48-hour case capacity means you're not charging constantly. I'd pick the CHENRUIDA Open Ear Clip only if comfort and awareness are non-negotiable for you, or if the bracelet-and-mirror case is the kind of detail that makes you actually want to carry them. Different jobs, different tools. Since neither page here lists a price, check the current price on Amazon before you commit — that's the number that should break a tie this close.
FAQ
RCA states 6 hours per charge and up to 48 hours with the case; CHENRUIDA states 5 hours per charge and up to 40 hours total. RCA has the higher ceiling, but CHENRUIDA's case shows an exact battery percentage, which makes it easier to plan around.
Yes — they're IPX6 waterproof, lightweight, and the open-ear clip keeps you aware of traffic and other people. Just expect less bass and no isolation compared with a sealed in-ear bud like the RCA pair.
That's the design intent. The flexible earhooks anchor each 7.8g bud over the ear, and the three included silicone tip sizes let you dial in a seal. For heavy lifting and running, that's a more secure setup than a plain in-ear bud.
Both include microphones with noise cancellation for calls — ENC on the RCA Earbuds and environmental noise cancellation on CHENRUIDA. Both are wireless Bluetooth and work with iOS, Android and other Bluetooth devices.
