If you want marathon-grade battery life and a secure earhook fit for hard training, choose GTbeans Open Ear Earbuds; if you need the lightest possible clip-on with Hi-Res LDAC audio and dual-device switching, choose Linklike Air Open Ear.
• GTbeans Open Ear Earbuds — biggest strength: a genuine battery fortress, with 16 hours on a single charge and 56 hours total with the case, plus a 16mm dynamic driver for a bass-forward sound.
• GTbeans Open Ear Earbuds — biggest trade-off: earhook design and a larger 44g case make it the bulkier, more "sport kit" of the two.
• Linklike Air Open Ear — biggest strength: featherweight comfort at just 5g per bud, a patented clip-on Z-Structure, and Hi-Res LDAC with a 10.8mm carbon fiber driver.
• Linklike Air Open Ear — biggest trade-off: shorter endurance at 6 hours per charge and 42 hours with the case, and no active noise cancellation by design.
• Who GTbeans is for: runners, cyclists and shift workers who want to charge rarely and never think about battery anxiety.
• Who Linklike Air is for: all-day wearers, students, commuters and gamers who prioritise near-weightless comfort and low-latency, high-resolution audio.
The GTbeans E20 is built around two ideas: staying put and staying charged. The ergonomic arc pairs 2.8mm slim earhooks with a 0.7mm titanium memory wire, so the hook can flex to your ear shape and hold tension through movement, while the skin-friendly silicone covering keeps it comfortable. At 8.58g per bud it's light enough for long sessions, and the open-ear design lets air flow so your ears don't feel sealed or sweaty.
The spec that really separates it is power. You get 16 hours of playback on a single charge and 56 hours with the case topping it up, plus fast charging that gives you 2 hours of use from a 10-minute top-up. That combination is aimed squarely at people who forget to charge: cyclists, runners, gym regulars, and anyone on a long shift who doesn't want a dead bud halfway through.
Buy it if you want the longest possible runtime, a hook that survives burpees, and bass you can feel. Skip it if you want the absolute lightest bud, the smallest case, or app-based EQ — the E20 offers none of those.
Linklike Air Open Ear: Who It's For
The Linklike Air takes the opposite approach: shave every gram and engineer the fit like jewellery. Each bud is just 5g, and the patented 3.0 Z-Structure uses a silicone teardrop contact surface to spread pressure instead of clamping down — Linklike says it was developed around 3600+ ear profiles and claims it fits essentially all ear shapes, including small ear canals. The mirrored left/right ergonomics and flexible memory-wire bridge let you fine-tune tension for what the brand calls a zero-pressure feel.
Sound is where this one gets interesting for the price-conscious audiophile crowd. It uses a 10.8mm BPU carbon fiber driver with dual-magnet power and supports Hi-Res LDAC, which is a step above standard Bluetooth codecs and typically means more detail and a warmer low end. Bluetooth 6.0 adds ultra-low latency for gaming and video, and a dual-device link lets you jump between a laptop meeting and your phone without re-pairing.
Battery is 6 hours per charge and 42 hours total with the case, recharging fully in about 1.5 hours. It's IPX5 rated for rain and heavy sweat, and — worth flagging — it deliberately has no noise cancellation, because the whole point of open ear is staying aware of traffic and surroundings. You also get a 2-year warranty and a premium gift box.
Buy it if you wear earbuds for hours and hate the feeling of anything clamped to your ear, or you want LDAC detail and low-latency gaming. Skip it if you need maximum runtime or noise cancellation.
Side-by-Side: Which Should You Choose?
• Best for all-day comfort → Linklike Air Open Ear. 5g per bud with a pressure-spreading clip beats an 8.58g earhook for long wear.
• Best for runners and cyclists → GTbeans Open Ear Earbuds. The titanium memory-wire hook and IP55 nano-coating are built for sweat and motion.
• Best for high-resolution audio → Linklike Air Open Ear. LDAC plus a carbon fiber driver is the more audiophile-leaning spec sheet.
• Best for gaming and video → Linklike Air Open Ear. Bluetooth 6.0 with ultra-low latency and lip-sync precision is the gaming-focused feature here.
• Best for calls in noisy places → GTbeans Open Ear Earbuds. Four beam-forming mics with environmental noise cancellation is the stronger mic array on paper.
• Best for travel and portability → Linklike Air Open Ear. A 5g bud and compact clip-on shape pack down smaller than a hook-style set.
• Best for switching between laptop and phone → Linklike Air Open Ear. The seamless dual-device link is the standout convenience feature.
In my opinion, the Linklike Air Open Ear is the one I'd pick for everyday life. At 5g per bud it disappears on your ear, LDAC and the carbon fiber driver give you genuinely better sound quality, and dual-device switching is the kind of feature you use every single day. If your priority is never touching a charger — or you train hard and want a hook that won't budge — the GTbeans E20 is the better buy, and its 56-hour total runtime is hard to argue with. Two very different philosophies: weightless audio versus endless battery. Check the current price on Amazon before you decide, since that's the one variable that can flip this call.
FAQ
how to wear tws earbuds
For the GTbeans E20, loop the earhook over your ear and let the 0.7mm titanium memory wire settle against your ear shape — it should sit lightly, not press. For the Linklike Air, align the L and R marks first, then clip the silicone teardrop onto your ear and adjust the memory-wire bridge until it feels weightless.
how to use tws earbuds
how to open tws earbuds
"Opening" usually means getting them out of the case and powered on. Both ship with a charging case — the GTbeans case measures roughly 3.07 by 2.48 by 0.9 inches — so you lift the lid, take out the buds, and they power on and reconnect to your last paired device automatically.
how to operate tws earbuds
Operation is all touch-based on both models. Expect taps for play/pause and track skipping and a hold gesture for other functions, and both include a user manual in the box that lists the exact tap map. The GTbeans E20 also has a 1-year warranty, while the Linklike Air carries 2-year coverage.
