How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the better all-round daily earbud with stronger bass, serious waterproofing and a long battery case, choose OAIXRYQ Earbuds; if you need open-ear comfort plus built-in AI translation across 165 languages, choose JKNKCO NE39.
• OAIXRYQ Earbuds — biggest strength: a sealed in-ear design with 14.2mm dynamic drivers, a claimed 43% more bass, ENC call noise reduction with four microphones, and an IPX8 waterproof rating that handles sweat and rain without drama.
• OAIXRYQ Earbuds — biggest trade-off: it's a traditional in-ear bud, so it plugs your ear canal and there's no translation feature or open-ear ambient awareness.
• JKNKCO NE39 — biggest strength: open-ear earhooks that keep your ear canals unblocked, plus AI online translation covering 165 languages and 8 modes through the SayMi app — a genuinely different kind of product.
• JKNKCO NE39 — biggest trade-off: translation only works through the dedicated app and needs a cellular or WiFi connection, with no offline mode, and the open acoustic structure means you won't get the same sealed-in bass feel.
• Pick OAIXRYQ if you want a straightforward HiFi stereo music and call earbud for workouts, commutes and long listening sessions.
• Pick JKNKCO NE39 if you're a traveler, cyclist or language learner who values hearing your surroundings and wants translation on tap.
The OAIXRYQ Earbuds are built around one idea: give you a solid, sealed in-ear listening experience that survives real life. The 14.2mm dynamic drivers paired with a high-resolution decoder are the headline for sound — that's a fairly large driver for a true wireless bud, and the spec sheet frames it around deep bass with a claimed 43% boost. If your playlist leans toward hip-hop, electronic or anything rhythm-driven, that's the kind of tuning you notice immediately. The 38 ohm impedance and 88 dB sensitivity figures suggest a set that's easy enough to drive from a phone without any external amp.
Battery is the other strong card. You get up to 8 hours on a single charge and up to 48 hours total with the charging case, plus fast charging that the description pegs at 10 minutes for 2 hours of playback. That's the difference between a bud you charge every night and one you can genuinely forget about for a few days. Bluetooth 5.4 handles the connection side, with instant pairing when you lift the buds out of the case and auto-reconnect to the last device, and the supported profiles (HFP, HSP, A2DP, AVRCP) cover calls, music and remote control properly.
For calls, there are four microphones working with ENC noise reduction, which is designed to suppress background noise and push your voice forward in busy places. The IPX8 rating is the spec I'd point to most for anyone active — that's a sealed shell with nano-coating, so sweat, rain and a rinse under the tap are all in scope. At roughly 4g per bud and a 29g case, they disappear into a pocket.
Who should skip it: if you hate the plugged-up feeling of in-ear tips, or you specifically want translation features, this isn't the one.
JKNKCO NE39: Who It's For
The JKNKCO NE39 is a different animal entirely. It's an open-ear earhook design, which means the driver sits outside your ear canal rather than inside it. The practical upside is comfort and awareness: no pressure build-up after hours of wear, and you can still hear traffic, announcements and people talking to you. For cyclists, runners on shared paths, and drivers who need to stay alert, that open acoustic structure isn't a gimmick — it's the whole point.
Then there's the feature nobody else in this comparison has: AI online translation across 165 languages with 8 translation modes, handled through the dedicated SayMi app. For overseas travel, mixed-language households or anyone studying a second language, that's a real capability rather than a marketing line. Two caveats matter, though. First, translation only works through that app. Second, it requires a cellular or WiFi connection — there's no offline translation at all. If you're heading somewhere without reliable data, plan around that.
On the audio side, JKNKCO pairs a Bluetooth 6.0 chip with built-in speaker drivers tuned for 360° spatial HiFi stereo. The newer Bluetooth generation is framed around fast pairing, low latency and stable anti-interference in crowded places like stations and airports, which is exactly where cheap buds tend to stutter. Battery life is listed at 40 hours with the case, and the whole package is light — about 3.52 ounces including the case — with a slim, pocket-sized form and minimalist silver and beige colorways.
Who should buy it: travelers, cyclists, commuters, language learners and anyone who finds in-ear buds uncomfortable after an hour.
Who should skip it: if you want maximum bass isolation or need translation to work without a network connection, look elsewhere.
• Best for bass-heavy music → OAIXRYQ Earbuds. The 14.2mm dynamic drivers and the claimed 43% bass boost are aimed squarely at low-end punch.
• Best for workouts and rain → OAIXRYQ Earbuds. IPX8 is the highest water resistance rating in this comparison, and the sealed shell backs it up.
• Best for total battery life → OAIXRYQ Earbuds. Up to 48 hours with the case beats the 40 hours listed for the NE39, and fast charging adds a safety net.
• Best for call clarity in noise → OAIXRYQ Earbuds. Four microphones with ENC noise reduction is the more call-focused setup on paper.
• Best for travel and translation → JKNKCO NE39. 165 languages, 8 modes, no subscription framing — nothing else here comes close.
• Best for situational awareness → JKNKCO NE39. The open-ear earhooks keep your canals clear, which matters on roads and shared paths.
• Best for all-day comfort → JKNKCO NE39. Open-ear designs avoid the soreness that sealed tips can cause over long sessions.
• Best for newer connectivity → JKNKCO NE39. Bluetooth 6.0 versus 5.4, with the low-latency and anti-interference claims that go with it.
In my opinion, the OAIXRYQ Earbuds are the safer buy for most people. The combination of big-driver bass, IPX8 waterproofing, 48-hour case battery and a four-mic call setup covers the everyday jobs — gym, commute, calls, long listening — with no caveats attached. The JKNKCO NE39 is the more interesting product, and if translation or open-ear awareness is your reason for shopping, it's the only one of the two that does those things at all. But that translation depends on an app and a live connection, and the open design trades isolation for awareness. If you don't specifically need either of those two things, the OAIXRYQ is the one I'd reach for.
what hifi wireless earbuds
Both of these are HiFi stereo wireless earbuds, just with different approaches. The OAIXRYQ uses 14.2mm dynamic drivers in a sealed in-ear design for deep bass, while the JKNKCO NE39 uses speaker drivers in an open-ear earhook design tuned for 360° spatial stereo. Which is "HiFi" for you depends on whether you want isolation or awareness.
what hifi earbuds
HiFi earbuds are ones built around higher-resolution audio processing and capable drivers rather than basic playback. The OAIXRYQ pairs its 14.2mm dynamic drivers with high-resolution decoder technology and a 38 ohm impedance, while the NE39 pairs a Bluetooth 6.0 chip with spatial stereo drivers. Both are positioned as HiFi stereo, at very different price points — check the current price on Amazon to compare.
what are the best hifi wireless earbuds
There's no single answer, because "best" depends on your use case. For bass, waterproofing and battery life, I'd point to the OAIXRYQ Earbuds. For travel with translation and open-ear comfort, the JKNKCO NE39 is the more capable pick. Match the specs to how you'll actually use them rather than chasing a universal winner.
do open-ear earbuds sound worse than in-ear earbuds
Not worse — different. Open-ear designs like the JKNKCO NE39 leave your ear canal unblocked, so you lose the passive isolation and sealed-in bass feel that in-ear buds like the OAIXRYQ provide. In exchange you get ambient awareness and comfort over long sessions. Neither approach is objectively better; it comes down to whether you prioritize bass impact or hearing your surroundings.
