If you want a single wearable that keeps a pair of true wireless earbuds tucked inside the watch itself, choose Desong Watch; if you need two genuinely different pairs of earbuds in one case — an open-ear set for awareness and an in-ear set for focus — choose RCA EarSwitch Pro 4-in-1. For swimming, neither is built for laps, but the Desong's IP67 rating and hidden earbud compartment make it the more practical poolside companion, so that's the one I'd lean toward if water resistance is your priority.
• Desong Watch's biggest strength: a 2.02-inch HD screen with true wireless earbuds hidden inside the watch body, plus a 300 mAh battery rated for 12-day standby and 2–3 recharges of the buds.
• Desong Watch's biggest trade-off: the buds sit in a compartment under the screen, so you're locked into that one pair — and IP67 covers sweat, rain and handwashing, not swimming.
• RCA EarSwitch Pro's biggest strength: a 4-in-1 system giving you two pairs of buds (open-ear + in-ear) in one LED charging case, with Bluetooth 5.4 and up to 6 hours of playtime.
• RCA EarSwitch Pro's biggest trade-off: no watch, no fitness tracking, and no water-resistance rating listed — it's an audio-first product, not a wearable.
• Pick Desong Watch if you want one device on your wrist that handles calls, notifications, fitness tracking and music, and you'd rather not carry a separate earbud case.
• Pick RCA EarSwitch Pro if you want maximum audio flexibility — open-ear for awareness, in-ear for immersion — and you don't care about a screen or sports metrics.
The Desong Watch is a wearable first and an audio product second, and that ordering matters. The pitch is a 2.02-inch HD touchscreen watch with a pair of TWS earbuds stored in a hidden compartment beneath the display. That compartment is the real design story here: because the buds live inside the watch, they're protected from dust and accidental drops, and they won't go flying out mid-workout the way a loose case can. In my opinion, that single design decision is what makes this product worth a look — it solves the "where do I put my earbuds" problem for people who hate carrying a second case.
On the fitness side, the spec sheet is genuinely broad. You get step counting, dynamic heart rate monitoring, sleep tracking, calorie calculation, a sedentary reminder, a water-drinking reminder, an alarm, a stopwatch and more than 100 sports modes — walking, running, cycling, climbing, yoga, skiing, football and treadmill among them. There's also a breathing exercise function, music control, weather, a calculator and even games, plus GPS functionality routed through your phone. Call and message notifications come through the watch, and you can answer calls with one tap, either on the watch or through the buds. It pairs with Android 5.0+ and iOS 9.0+.
The battery picture is the part I'd flag for heavy users. The 300 mAh cell charges in about 2 hours and is rated for up to 12 days of standby, while the earbuds recharge automatically when you drop them back into the watch and are rated for 2–3 full charges, delivering up to 3.5 hours of non-stop music. That's fine for commutes and workouts; it is not a "leave them in all day" arrangement.
Who should buy it: someone who wants one thing on their wrist that handles calls, notifications, fitness metrics and music without a separate earbud case. Who should skip it: anyone who wants premium audio tuning, long continuous listening sessions, or a device they can actually swim with. IP67 handles sweat, rain and handwashing — it is not a lap-swimming rating.
The RCA EarSwitch Pro takes the opposite approach: it's an audio product, full stop, and it throws versatility at you instead of features. The headline is the "4-in-1 Duo" system — two complete pairs of true wireless earbuds, one traditional in-ear style and one open-ear design, both living in a single LED charging case. Switch to the open-ear pair when you need to hear traffic, a coach or a coworker; switch to the in-ear pair when you want to shut the world out. In my opinion, that's a genuinely useful idea for anyone who currently owns two sets of buds for two different situations.
Under the hood, RCA leans on Bluetooth 5.4 for a stable connection and low-latency performance, and the buds use 2-MW drivers tuned for what the spec sheet calls "Ultra Bass." The open-ear design is explicitly about situational awareness, while the in-ear set is the one you reach for in the gym or the office. Noise-reduction technology is part of the package, though the open-ear half is by definition about letting sound in rather than blocking it out.
Playtime is rated at up to 6 hours of continuous talk and music on a single charge, with a "Faster Charge" internal battery and an LED display on the case that shows battery levels at a glance. Controls are touch-based — play, pause, volume, and hands-free calls — and the system works with Google Assistant and Siri for voice control. RCA lists a 1-year warranty.
Who should buy it: athletes, commuters and office workers who want two distinct listening modes without buying two separate products, and who value situational awareness on one pair and immersion on the other. Who should skip it: anyone who wants a screen, fitness tracking, heart rate or sleep data — none of that exists here. There's also no water-resistance rating listed, so if you're hunting for earphones for swimming, this isn't the spec you're looking for.
• Best for fitness tracking → Desong Watch. Heart rate, sleep, steps, calories and 100+ sport modes are all built in. The RCA has none of this.
• Best for audio flexibility → RCA EarSwitch Pro. Two pairs of buds, two listening styles, one case. Nothing else here matches that.
• Best for battery endurance on the wrist → Desong Watch. Up to 12 days of standby, with 2–3 recharge cycles for the buds from the watch itself.
• Best for continuous listening per charge → RCA EarSwitch Pro. Up to 6 hours of playtime per charge versus up to 3.5 hours of music from the Desong buds.
• Best for staying aware of your surroundings → RCA EarSwitch Pro. The open-ear pair exists specifically for that; the Desong buds are standard in-ear TWS.
• Best for one-device simplicity → Desong Watch. Watch, notifications, calls and music in a single item on your wrist — no second case to remember.
• Best for connectivity spec → RCA EarSwitch Pro. Bluetooth 5.4 versus the Desong's Bluetooth (no version listed).
• Best for water resistance → Desong Watch. IP67 covers sweat, rain and handwashing. The RCA lists no water-resistance rating.
If I had to pick one, I'd buy the Desong Watch — and it comes down to consolidation. One device on my wrist that tracks my activity, shows notifications, answers calls and holds its own earbuds is a cleaner setup than juggling a watch and a separate charging case. For swimming specifically, its IP67 rating is the closest thing to water confidence between these two, though I'd still treat it as splash-and-sweat protection rather than a lap-swim guarantee. The RCA EarSwitch Pro is the better audio product and the smarter buy if two listening modes matter more to you than a screen — but for a single everyday wearable, my vote goes to the Desong.
how to connect tws earbuds
On the Desong Watch, you pair the watch and its hidden earbuds over Bluetooth with an Android 5.0+ or iOS 9.0+ phone. On the RCA EarSwitch Pro, you pair via Bluetooth 5.4 to a phone, tablet or laptop. Both are standard wireless pairings — no cables involved.
how to pair tws earbuds
For the RCA set, the two bud styles share one LED charging case, so you pair whichever pair you're using through your device's Bluetooth menu. For the Desong, the buds live under the watch screen and recharge when docked, so you pair them alongside the watch itself.
how to reset tws earbuds
Neither data sheet lists a specific reset procedure, so I won't invent one. The practical reset for either product is to unpair them from your phone's Bluetooth list and re-pair from scratch, which clears most connection hiccups.

If you mean "how do TWS earbuds work" — true wireless stereo means the two buds connect to your device wirelessly with no wire between them. The Desong stores its pair inside the watch, while the RCA gives you an in-ear pair and an open-ear pair in one case.
