If you want earbuds that physically cannot fall out mid-sprint and never need charging, choose VJK Upgrade; if you need true wireless freedom with app-tuned sound and a pocket-size case, choose JLab Go Air Pop+.
• VJK Upgrade — biggest strength: Ear-hook stability. The wrap-around silicone loops plus IPX5 sweat resistance are built for running, cycling and gym work where bud slippage is the enemy.
• VJK Upgrade — biggest trade-off: It's wired. The 3.5mm jack means no Bluetooth, and newer phones without a headphone port need an adapter.
• JLab Go Air Pop+ — biggest strength: True wireless convenience with serious stamina: 9+ hours per bud, 26+ extra hours in the case, Bluetooth 5.3, and app-based EQ presets.
• JLab Go Air Pop+ — biggest trade-off: No ear hooks and no official water-resistance rating in the specs, so heavy sweat sessions and rough trail runs aren't its home turf.
• Pick VJK Upgrade if you want a locked-in fit and don't mind a cable.
• Pick JLab Go Air Pop+ if you want cable-free listening, long battery life and sound you can tune yourself.
The VJK Upgrade is a wired sports earbud built around one problem: staying in your ear. VJK redesigned the ear hooks so they wrap around the back of your ear, and the hybrid soft silicone loops are shaped to sit comfortably even if you wear glasses. The result is a fit that doesn't rely on a tight seal alone — it relies on geometry. For runners, hikers, cyclists and anyone doing burpees, that matters more than almost any spec.
The audio side is honest and practical. A 16-ohm impedance, 97dB sensitivity and a dynamic driver covering 20Hz–20kHz mean these are easy to drive from a phone or laptop without a headphone amp. The in-ear seal does double duty: it helps deliver bass and isolates outside noise, which is exactly what you want when you're jogging next to traffic you'd rather tune out. The IPX5 rating covers sweat and moisture spray, so a hard workout won't kill them.
Who should buy it: athletes and gym-goers who are tired of buds popping out, people who prefer the zero-latency simplicity of a wired connection, and anyone whose device still has a 3.5mm jack. Who should skip it: if you want to charge nothing and carry nothing, or you need wireless freedom for calls across the room, this isn't your pair — and note the fit isn't designed for small children.
JLab Go Air Pop+: Who It's For
The JLab Go Air Pop+ is a true wireless earbud that leans hard into convenience. Take the buds out of the charging case and they power on and pair with each other automatically; from there you connect to your phone over Bluetooth 5.3, which JLab describes as its fastest handsfree connection yet. No cable, no jack, no adapter drama — just a case in your pocket.
That case is genuinely small. JLab says it's smaller than a credit card, and the buds themselves are 15% smaller and 40% lighter than the Go Air, which makes them easy to carry for a run or toss in a bag. Battery life is the headline number: 9+ hours in each earbud, plus 26+ hours from the case, for 35+ hours total. The case recharges over an integrated USB-C cable, and a quick 10-minute top-up buys about an hour of playtime — handy when you're heading out the door and realize you forgot to charge.
Sound is customizable rather than fixed. The 6mm dynamic driver covers 20Hz–20kHz, and the JLab app lets you switch between EQ presets like JLab Signature, Balanced and Bass Boost, adjust the Be Aware mode that lets ambient sound in for safer outdoor listening, and remap touch controls. Each bud has a built-in MEMS microphone, and you can use either earbud solo or both together. This bundle also includes Cloud Foam earbud tips designed to expand in your ear for a never-slip fit, along with three gel tip sizes to dial in the seal.
Who should buy it: commuters, casual gym users, students and anyone who wants wireless earbuds with app-tuned sound, long battery life and a case that disappears into a pocket. Who should skip it: if your priority is a mechanical, hook-based fit for intense sport, or you specifically need a 3.5mm wired connection for a device without Bluetooth.
• Best for intense sport and sweat → VJK Upgrade. The ear hooks and IPX5 rating are purpose-built for running, cycling and gym sessions.
• Best for battery life and wireless freedom → JLab Go Air Pop+. 9+ hours per bud and 35+ hours total with the case, all without a cable.
• Best for sound customization → JLab Go Air Pop+. EQ presets and Be Aware mode in the JLab app give you control the VJK simply doesn't offer.
• Best for zero-latency, plug-and-play use → VJK Upgrade. A 3.5mm jack means no pairing, no charging, no dropouts — plug in and go.
• Best for glasses wearers → VJK Upgrade. The soft silicone ear loops are specifically shaped to stay comfortable alongside glasses.
• Best for pocketability → JLab Go Air Pop+. A case smaller than a credit card beats a 1.2m cable you have to coil and stow.
• Best for calls anywhere → JLab Go Air Pop+. Independent single-bud use and a MEMS mic in each bud make it the more flexible calling setup.
• Best for older phones and MP3 players → VJK Upgrade. The 3.5mm plated jack covers Android devices, MP3/MP4 players, laptops, tablets and desktops.
If I had to pick one, I'd buy the JLab Go Air Pop+ for everyday life — the true wireless setup, 35+ hours of total playtime and app-based EQ make it the more versatile companion for commuting, study and casual training. But if your workouts are the whole point, I'd take the VJK Upgrade instead: the ear-hook design and IPX5 sweat protection solve the one problem that ruins sports earbuds, and the wired connection never needs a charge. Match the pick to your routine, not the spec sheet, and check the current price on Amazon before you commit.
For running specifically, the VJK Upgrade has the edge. Its wrap-around ear hooks and IPX5 sweat resistance are designed to keep the buds locked in during rigorous activity, while the JLab Go Air Pop+ relies on its tip seal alone and has no listed water-resistance rating.
Yes — they're wireless, so they run on battery. JLab lists 9+ hours of playtime per earbud plus 26+ extra hours from the charging case, and a 10-minute quick charge gives roughly an hour of listening.
Not directly. The VJK Upgrade connects via a 3.5mm jack, so phones without a headphone port need a suitable adapter. If your phone still has a 3.5mm jack, it plugs straight in.
Both cover a 20Hz–20kHz frequency range with a dynamic driver, so the hardware is comparable on paper. The JLab Go Air Pop+ lets you adjust the tuning with EQ presets in the JLab app, while the VJK Upgrade leans on its in-ear seal to isolate noise and bring out bass. Which sounds "better" depends on whether you prefer a sealed wired fit or app-tuned wireless sound.
