If you want the longer-lasting, more water-resistant option for running, choose Visual Land Soundwave A1; if you need the newer Bluetooth version and a splashproof design with a translucent case, choose JVC Gumy. Both are in-ear true wireless earbuds with active noise cancellation and a transparency or ambient mode, so the real decision comes down to battery, water resistance, fit and connectivity. Here's how I'd split them.
• Visual Land Soundwave A1 — biggest strength: up to 40 hours of total playtime and a 15-minute quick charge that gets you roughly 5 hours of listening.
• Visual Land Soundwave A1 — biggest trade-off: IPX5 water resistance handles sweat and splashes but isn't built for full submersion.
• JVC Gumy — biggest strength: Bluetooth 5.4 with a 10-meter range, plus a low-latency gaming mode and a translucent case with a strap holder.
• JVC Gumy — biggest trade-off: IPX4 splashproof protection and a shorter 26-hour total battery mean more frequent charging.
• Visual Land Soundwave A1 is for you if long battery life and tougher water resistance matter most on your runs.
• JVC Gumy is for you if you want the freshest Bluetooth spec, a gaming mode, and a see-through case you can clip to a bag.
The Soundwave A1 leans hard into stamina. Visual Land rates it at up to 40 hours of total playtime, and the carrying case alone holds enough for about 30 of those hours. That's the kind of number that matters if you're the type who charges once and forgets about it for a week of commutes and workouts. The fast-charging figure is the real headline for me: 15 minutes on the cable gets you up to 5 hours of playback, which is genuinely useful when you're heading out the door and realize the case is empty.
Its noise cancellation comes from a 6-microphone array, and you can switch it off or flip to transparent mode when you want to stay aware of traffic, a running partner, or someone calling your name. For running specifically, the IPX5 rating means sweat and light rain won't be a problem. Combine that with three ear tip sizes and touch controls, and you have a set that's built to stay put and be operated without pulling your phone out mid-stride.
Who should buy it: runners and gym-goers who want the longest possible time between charges, plus anyone who values a quick top-up before a workout. The balanced armature driver covers a 20Hz–20,000Hz range, and Bluetooth 5.3 keeps the connection current.
Who should skip it: if you need full waterproofing for poolside or heavy-rain use, or you specifically want the newest Bluetooth version and a gaming mode, look elsewhere. IPX5 is splash-and-sweat resistant, not submersible.
The Gumy Premium takes a different angle. JVC built it around Bluetooth 5.4, the newer of the two specs here, with a stated 10-meter range. In practice that means a stable connection that holds up when your phone is on a treadmill tray or across the room. The low-latency gaming mode is a bonus that the Soundwave A1 simply doesn't advertise — useful if you also game or watch video and hate lip-sync lag.
Battery is where it gives ground: 26 hours total, split as 6 hours per charge plus 20 from the case. That's still a full week of short sessions for most people, but it's meaningfully less headroom than the Soundwave A1. Charging takes about 2 hours for the buds and 2 hours for the case, so there's no fast-charge claim to lean on here.
The design details are where the Gumy wins hearts. An ergonomic stem design with four ear tip sizes (S/M/L/XL) is a genuine fit advantage for people whose ears sit between standard sizes. The translucent case in Olive Black, Coconut White, Mocha Brown or Grape Yogurt looks distinctive, and the strap holder lets you clip it to a bag or keychain. Audio comes from a 6mm dynamic driver at 16 ohm impedance, covering the same 20Hz–20,000Hz range.
Who should buy it: anyone who wants the newest Bluetooth, a low-latency mode for gaming and video, and a case they'll actually enjoy carrying. The IPX4 rating covers sweat, light rain and workout moisture.
Who should skip it: if you run long distances in unpredictable weather or want maximum battery, the Soundwave A1's IPX5 and 40-hour figure are the safer bet.
Side-by-Side: Which Should You Choose?
• Best for battery life → Visual Land Soundwave A1. Up to 40 hours total versus 26 for the Gumy.
• Best for quick top-ups → Visual Land Soundwave A1. 15 minutes of charging yields up to 5 hours; the Gumy takes about 2 hours to charge.
• Best for the newest Bluetooth → JVC Gumy. Bluetooth 5.4 with a 10-meter range versus 5.3.
• Best for gaming and video → JVC Gumy. Its low-latency mode targets audio delay; the Soundwave A1 lists no equivalent.
• Best for fit options → JVC Gumy. Four ear tip sizes versus three, though both aim for a secure in-ear seal.
• Best for microphone count → Visual Land Soundwave A1. A 6-mic array drives its noise cancellation and transparency mode.
• Best for case personality → JVC Gumy. Translucent shell, four colors and a strap holder versus a straightforward grey plastic case.
For running, I'd buy the Visual Land Soundwave A1. The combination of up to 40 hours of total playtime, a 15-minute fast charge, and IPX5 water resistance is exactly what a runner wants: fewer charges and more sweat tolerance. The 6-mic ANC with a transparent mode also gives you the situational awareness you need near traffic. In my opinion, the JVC Gumy is the better pick if you're a gamer or video watcher who prizes Bluetooth 5.4, a low-latency mode and a stylish translucent case — but for the specific job of being a wireless headphone for running, the Soundwave A1's battery and water rating win it for me.
what is ambient mode on earbuds
Ambient mode — sometimes called transparent mode — is a setting that pipes outside sound back into your ears through the earbuds' microphones so you can hear your surroundings without removing them. Both the Visual Land Soundwave A1 and JVC Gumy offer it. On the Soundwave A1 it's driven by a 6-microphone array and can be switched on when you need awareness.

In short, it's the opposite of active noise cancellation. ANC blocks chatter and traffic; ambient mode lets those sounds through on purpose. Both earbuds here include active noise cancellation alongside the ambient option, so you can flip between blocking the world out and letting it back in.
Do these earbuds work for running in the rain?
The Visual Land Soundwave A1 carries an IPX5 water-resistance rating, and the JVC Gumy carries IPX4 splashproof protection. Both handle sweat and light rain during a run. Neither is rated for full submersion, so I wouldn't swim or soak either one.
The Visual Land Soundwave A1 lasts longer overall, with up to 40 hours of total playtime versus 26 hours for the JVC Gumy. The Soundwave A1 also charges faster, giving up to 5 hours from a 15-minute charge, while the Gumy takes about 2 hours to charge.
