• Buoikik's biggest strength: The LCD touch display on the charging case plus active noise cancellation and a low-latency mode — a lot of control and features packed into a small package.
• Buoikik's biggest trade-off: Playtime is rated at 6–8 hours on a single charge, which is modest compared to the QXUFV's much longer total battery life.
• QXUFV's biggest strength: True open-ear design with a 9.5g weight, IPX7 waterproofing, 48 hours of total playtime, and 164-language real-time translation.
• QXUFV's biggest trade-off: No active noise cancellation and no built-in display on the buds themselves — the LED display is on the charging case, and noise control is listed as "None."
• Who Buoikik is for: Buyers who want an in-ear fit with noise blocking, a touchscreen case, and gaming-oriented low latency.
• Who QXUFV is for: Runners, cyclists, and travelers who want to hear their surroundings, stay dry in rain, and translate languages on the fly.
The Buoikik Q31 is built around control and immersion. The standout design element is the full-color LCD touchscreen on the charging case — the main interface puts sound effects, settings, QR codes, and volume right on the case itself, so you tap to navigate instead of digging through your phone. That's a genuinely unusual feature in this category, and it's the first thing that separates this model from a typical pair of sport buds.
On the audio side, the Buoikik uses a dynamic driver and includes active noise cancellation, which blocks outside noise for focused listening, calls, and gaming. There's also a low-latency mode aimed at gamers, keeping audio in sync with in-game action. Bluetooth 5.4 handles the wireless connection, and the touch controls live on the buds themselves, with Alexa listed as the control type. Battery life is rated at 6–8 hours per charge, with a one-hour charge time and a charging case that measures about 5 × 4 × 3 cm and weighs 20g. Multiple ear tip sizes are included, and the whole package is white with a black case.
Who should buy it: If you want noise cancellation, a touchscreen case you can actually interact with, and low-latency performance for gaming, the Buoikik is the more feature-dense pick. It suits someone who wants an in-ear fit that seals and blocks the world out.
Who should skip it: If long battery life is your priority, or if you specifically want to keep your ear canals open for safety while running outdoors, look at the QXUFV instead. The Buoikik's in-ear design and 6–8 hour runtime won't match an open-ear model on either front.
The QXUFV QX68 is designed around a very different idea: staying aware. The open-ear build rests gently around your ears and keeps your ear canals completely open, so you can hear approaching cars while running or cycling. It's also remarkably light at just 9.5g, using skin-friendly materials meant for all-day wear without ear fatigue. That combination — open fit plus low weight — is the core of the pitch, and for outdoor athletes it's a real safety argument, not a marketing one.
Sound comes from upgraded 14.2mm dynamic drivers delivering HD stereo and clear calls via an HD mic, with bass tuned to add energy during workouts. Bluetooth 5.4 connects up to 15 meters and reconnects automatically after the first pairing. Touch controls handle play/pause, calls, volume, track switching, and voice assistant activation, and the buds pair with phones, tablets, and computers.
Battery is where the QXUFV pulls ahead: 48 hours total playtime with up to 10 hours of continuous use per bud, and an LED display on the charging case shows remaining power in real time. The IPX7 waterproof rating means sweat and rain aren't a concern. Then there's the feature that makes this model genuinely different — 164 built-in languages for real-time translation through the Ear Dance app, with no subscription required. For travelers and language learners, that's a capability the Buoikik simply doesn't offer. The QXUFV comes in pink, with a matching pink case, and ships with two earbuds, a cable, and a manual.
Who should buy it: Runners, cyclists, gym-goers, and travelers who want open-ear awareness, IPX7 water resistance, long battery life, and translation built in.
Who should skip it: If you want active noise cancellation to shut out the world, the QXUFV isn't the tool — noise control is listed as "None," and the open design is the opposite of isolating by nature.
• Best for battery life → QXUFV Open Ear Headphones. 48 hours total with 10 hours per bud beats the Buoikik's 6–8 hour rating.
• Best for noise blocking → Buoikik Open-Ear Earbuds-Bluetooth 5.4. It's the only one of the two with active noise cancellation.
• Best for outdoor safety → QXUFV Open Ear Headphones. The open-ear design keeps your ear canals clear so you hear traffic and hazards.
• Best for gaming → Buoikik Open-Ear Earbuds-Bluetooth 5.4. Low-latency connectivity is built in specifically for in-game sync.
• Best for travel and language barriers → QXUFV Open Ear Headphones. 164 languages with real-time translation and no subscription.
• Best for sweat and rain → QXUFV Open Ear Headphones. IPX7 waterproofing is an explicit rating; the Buoikik sheet doesn't state a comparable IP rating.
• Best for hands-on control → Buoikik Open-Ear Earbuds-Bluetooth 5.4. The LCD touchscreen case gives you settings and volume without touching your phone.
• Best for all-day light wear → QXUFV Open Ear Headphones. At 9.5g with an open fit, it's built to disappear on your head.
If I were buying for myself, I'd pick the QXUFV Open Ear Headphones. The combination of a true open-ear fit, 9.5g weight, IPX7 waterproofing, 48 hours of playtime, and 164-language translation covers more of my real-world days — commuting, running, and traveling — than a touchscreen case does. In my opinion, the Buoikik wins on features you interact with, while the QXUFV wins on the things you actually feel: comfort, battery, and staying aware. If noise cancellation and gaming latency matter more to you than any of that, go with the Buoikik.
FAQ
The QXUFV is rated at 48 hours total with up to 10 hours of continuous use per bud. The Buoikik is rated at 6–8 hours on a single charge with a one-hour charge time. If runtime is your deciding factor, the QXUFV is the clear choice.

The QXUFV. It carries an IPX7 waterproof rating, so it resists sweat and rain. The Buoikik's data sheet doesn't list a comparable waterproof rating, so I'd treat the QXUFV as the safer bet for wet conditions. As for cost, check the current price on Amazon for both before deciding.
