If you want a lightweight, simple pair of earbuds with a clear battery readout and voice-assistant control, choose The Voice Duo True; if you need active noise cancellation and a touchscreen case that lets you change EQ modes without touching your phone, choose jaddsa Earbuds. These two are aimed at pretty different buyers, and the specs make that split obvious.
• The Voice Duo True — biggest strength: A translucent magnetic charging case with an LCD screen showing live battery status, plus 20 hours of total playtime (4 in the buds, 16 more from the case) and Siri/Google Assistant support.
• The Voice Duo True — biggest trade-off: Bluetooth 5 and no active noise cancellation, so it's a straightforward everyday set rather than a feature-loaded one.
• jaddsa Earbuds — biggest strength: Active Noise Cancellation, Bluetooth 5.4, and a multifunctional touchscreen charging case that handles volume, track skipping, calls, EQ presets, and even a "locate earbuds" function.
• jaddsa Earbuds — biggest trade-off: The touchscreen case is a more complex system to learn, and the sport-focused design is a different intent than a simple pocket pair.
• Pick The Voice Duo True if you want fuss-free auto-pairing, voice commands, and a visible battery readout at a glance.
• Pick jaddsa Earbuds if you want to block out gym noise and tweak your sound without pulling out your phone.
The Voice Duo True is built around simplicity. The headline idea is that you take the buds out of the case and they connect — auto-pairing recalls your previously paired device automatically, and the auto on/off puts them to sleep while they sit in the case and wakes them when you take them out. For someone who hates fiddling with Bluetooth menus, that alone is the selling point.
The charging case is the other standout. It's translucent, magnetic, and includes an LCD screen showing live battery status. That means you can see roughly how much juice is left without opening an app or guessing from a blinking light. The company rates total playtime at up to 20 hours — 4 hours from the earbuds themselves plus 16 more from the case — and a full recharge takes about 2 hours over the included USB cord. The whole package (case plus buds) measures about 2 by 2 inches and weighs 1.5 ounces, so it disappears into a pocket or bag.
On the audio and control side, you get a dynamic driver with a 20 Hz–20,000 Hz frequency range, Bluetooth 5 with a 10-meter range, and a built-in mic for hands-free calls. Tap the touchpad twice and you can talk to Siri or Google Assistant to ask for the weather, the time, or to start a playlist. It's compatible with both Android and iOS.
Who should buy it: Anyone who wants a light, no-drama pair for commuting, podcasts, audiobooks, and phone calls — especially iPhone or Android users who lean on a voice assistant and like seeing battery status at a glance. Who should skip it: If you train in a loud gym and want to mute the room, or you want to sculpt your sound with EQ presets, this isn't that product. There's no active noise cancellation here, and the controls are voice- and tap-based rather than a full touchscreen.
The jaddsa Earbuds go the other direction: more tech, more control. The centerpiece is the multifunctional touchscreen charging case. Instead of tapping the buds and hoping, you swipe and tap on the case itself to switch songs, adjust volume, take calls, flip between five EQ modes, and even locate a missing earbud. That "locate earbuds" function is a genuinely practical touch if you're the type to lose one bud in a gym bag.
Sound is handled by 12mm dynamic drivers, which the company describes as delivering punchy bass down to 40Hz alongside crisp highs. The five EQ presets — Rock, Hip-hop, Pop and others — are meant to be switched on the fly, so you can match the sound to whatever you're doing. Mid-workout, that's a nicer experience than digging your phone out of an armband.
The bigger differentiator is Active Noise Cancellation. For sports, workouts and gym use, ANC is the feature that actually changes the experience: it cuts the drone of treadmills, fans and gym chatter so you can hear your music at a lower, safer volume. Bluetooth 5.4 is the newest version here, which generally means a more stable, efficient connection than the older 5.0 standard. The buds are in-ear with eartips included, finished in Dark Blue, and backed by a 1-year warranty.
Who should buy it: Runners, lifters, and anyone who treats earbuds as workout gear first. If you want ANC, want to control everything from the case, and like the idea of tuning your sound with EQ presets, this fits. Who should skip it: If you want the simplest possible pair — take out, listen, put back — the touchscreen case is more system than you need, and you're paying in complexity for features you may never touch.

• Best for gym and workout use → jaddsa Earbuds. ANC plus the sport-oriented design and EQ presets are built for training.
• Best for battery visibility → The Voice Duo True. The LCD screen on the case shows live battery status; jaddsa's case relies on its touchscreen interface.
• Best for total playtime clarity → The Voice Duo True. The spec is explicit: up to 20 hours total, split as 4 hours in the buds plus 16 from the case.
• Best for newest Bluetooth → jaddsa Earbuds. Bluetooth 5.4 versus Bluetooth 5.
• Best for hands-free voice control → The Voice Duo True. Siri and Google Assistant are a double-tap away for weather, time, calls and music.
• Best for on-case controls → jaddsa Earbuds. Volume, tracks, calls, EQ and earbud-finding all live on the touchscreen case.

If I had to pick one for myself, I'd take the jaddsa Earbuds. In my opinion, Active Noise Cancellation and Bluetooth 5.4 are the two features that matter most day to day, and the touchscreen case genuinely removes the phone from the equation during a workout. That said, if you mostly listen at a desk, on transit, or while walking and you just want something light that pairs itself and shows its battery, I'd point you to The Voice Duo True instead — it's the calmer, simpler buy. Either way, check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
