How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day open-ear comfort with marathon battery life for workouts and music, choose Bulktech OWS True; if you need earbuds that translate 144 languages in real time with offline packs for travel and cross-language conversation, choose diujzld AI Translation Earbuds.
• Bulktech OWS True — biggest strength: Up to 60 hours of playback with a quick-charging case, plus IPX5 sweat and rain resistance and Bluetooth 5.3 with a 50-foot range. It is built to stay on your ears and keep going.
• Bulktech OWS True — biggest trade-off: No active noise cancellation and no translation features. It plays audio, it does not interpret the world for you.
• diujzld AI Translation Earbuds — biggest strength: Real-time translation across 144 languages with eight offline packs (Chinese, English, Japanese, Korean, Russian, German, French, Spanish), plus conversation, photo, audio recording, and video-call translation modes.
• diujzld AI Translation Earbuds — biggest trade-off: Up to 4 hours of continuous use per charge for translation or music, and a 10-meter Bluetooth range. That is a fraction of the Bulktech's endurance.
• Who each pick is for: Bulktech OWS True for runners, gym-goers, commuters, and anyone who lives in their earbuds all day. diujzld for travelers, language learners, meeting-heavy professionals, and anyone who talks across languages.
The OWS True is an open-ear headphone in the truest sense. Nothing plugs your ear canal. Instead, an earhook design holds a dynamic driver just outside it, and the frame is a 0.7mm memory-flex titanium alloy wrapped in skin-friendly silicone. That combination matters more than it sounds. Titanium memory-flex means the hook can flex to your ear shape without permanently bending out of shape, and silicone keeps it from digging in during a long day. If you have ever taken off a pair of in-ear buds after two hours because your canals felt raw, this is the category that fixes that.
Where it really pulls ahead is stamina. Bulktech rates it at up to 60 hours of music playback, and the quick-charging case alone gives 15 hours of use on a 1.5-hour charge. Read that again: a single case charge covers most people's entire week of workouts. Bluetooth 5.3 keeps the connection stable with low latency out to 50 feet, and AAC/SBC support covers the codecs your phone already uses. The IPX5 rating with a hydrophobic coating handles sweat and light rain, which is exactly the exposure an open-ear bud sees on a run or a rainy walk to the train.
Who should buy it: runners, cyclists, gym regulars, warehouse and delivery workers, and anyone who wants to hear traffic, coworkers, or their kids while music plays. Open-ear design is also the honest answer for people whose ears get sore or itchy from sealed buds.
Who should skip it: anyone who needs to disappear into their music on a plane. There is no noise cancellation here — noise control is listed as none — so engine roar and crowd noise come through. And if your actual problem is talking to someone in another language, this headphone has no answer for that. It is a music and call device, full stop.
The diujzld pair is a different animal entirely. It is also an OWS (open-wear style) earbud, so you get the same don't-plug-your-ears comfort, an ergonomic secure fit, and a lightweight portable build. But the headline is the translation engine: 144 languages in real time, with offline packs for Chinese, English, Japanese, Korean, Russian, German, French, and Spanish available inside the app. The included one-year free subscription covers the translation service.
The mode list is what makes it genuinely useful rather than a gimmick. Conversation mode handles face-to-face back-and-forth. Offline mode keeps translating without a network, which also means your audio isn't routing through a server — a fair privacy argument when you're discussing business or personal matters. Photo translation covers signs, menus, and documents. Audio recording translation handles lectures and meetings you want to review later. Video call translation covers the remote half of your life.
The trade-offs are real and worth stating plainly. Battery life is up to 4 hours of continuous use for translation or music, so this is a charge-often device, not a leave-in-your-bag-for-a-week one. Connectivity range is a stable 10 meters, roughly 33 feet — fine for a room, tighter than the Bulktech's 50 feet. And while a 2-year warranty and multiple color options are nice touches, this is not a workout headphone in the way the Bulktech is; nothing in the spec sheet claims a water-resistance rating.
Who should buy it: frequent travelers, international students, people with multilingual families or clients, sales and support staff on cross-border calls, and anyone who has ever stood in a foreign pharmacy trying to explain a symptom.
Who should skip it: pure music listeners and gym rats. You'd be paying for a translation stack you'd never open, and you'd give up a huge amount of battery life in the process.
• Best for battery life → Bulktech OWS True. Up to 60 hours versus up to 4 hours is not a close contest.
• Best for workouts and sweat → Bulktech OWS True. IPX5 with a hydrophobic coating is the only water-resistance rating between the two.
• Best for travel across language barriers → diujzld AI Translation Earbuds. 144 languages, eight offline packs, and five translation modes.
• Best for long-range freedom from your phone → Bulktech OWS True. 50 feet of Bluetooth 5.3 range versus 10 meters.
• Best for privacy-conscious conversations → diujzld AI Translation Earbuds. Offline mode translates without a network connection.
• Best for all-day wear without ear fatigue → either one. Both are open-ear designs built for comfort, so this one is a genuine tie.
• Best for students and meeting-heavy work → diujzld AI Translation Earbuds. Audio recording and video call translation modes are built for exactly that.
• Best for people who just want music all week → Bulktech OWS True. Fewer features, far more endurance, and a frame designed for movement.
In my opinion, most people searching this comparison should buy the Bulktech OWS True. Sixty hours of playback, IPX5 protection, a titanium memory-flex frame, and 50-foot Bluetooth range solve the problems open-ear buyers actually have: fit, sweat, and charging anxiety. I would only steer you to the diujzld AI Translation Earbuds if translation is the reason you're shopping — because if it is, no amount of battery life substitutes for 144 languages and offline packs. Decide which problem you're solving first. That answer picks the product for you.
FAQ
how to wear ows earbuds
how to use ows earbuds
Use them like any Bluetooth headphone: pair once, then play audio, take calls, and control playback with the on-ear buttons (the Bulktech uses push-button controls). The difference is awareness — because your canal stays open, you hear ambient sound at the same time. The diujzld pair adds a companion app where you select translation modes and download offline language packs.
how to connect tws earbuds
Take both earbuds out of the charging case and they should power on and pair with each other automatically. Then open your phone's Bluetooth settings, wait for the earbud name to appear, and select it. The Bulktech uses Bluetooth 5.3 with a range up to 50 feet, so keep your phone nearby during that first pairing.
how to pair ows earbuds
If your earbuds don't appear in Bluetooth settings, put them back in the case, close it, then reopen it to restart the pairing broadcast. On the phone side, toggle Bluetooth off and on and rescan. Once paired, both the Bulktech and the diujzld pair should reconnect automatically the next time you take them out of the case.
