How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, plug-and-play headset that keeps long calls clear and barely registers on your head, choose NUBWO HW02; if you need a wireless single-ear piece with built-in AI translation, hands-free calling and a charging case that keeps going all day, choose epekops AI.
• NUBWO HW02 — biggest strength: At just 60 grams with an on-ear design, an adjustable noise-minimizing boom mic and a USB + 3.5mm wired connection, it's a straightforward, always-ready headset for desk work and long voice sessions.
• NUBWO HW02 — biggest trade-off: It's wired, has no noise cancellation (noise control: None), and depends on your device's USB or 3.5mm port — no Bluetooth freedom.
• epekops AI — biggest strength: Bluetooth 6.1 wireless freedom plus an AI translator app for live spoken translation, ENC noise reduction, and up to 72 hours of total use with the charging case.
• epekops AI — biggest trade-off: It's a single-ear in-ear hook design, so it's not for immersive stereo listening, and the translation feature depends on pairing with the AI Translator app.
• Pick NUBWO HW02 if you live on MS Teams, Skype or Zoom calls at a desk and want a simple, comfortable wired headset.
• Pick epekops AI if you're on the move — driving, trucking, traveling or talking to people in another language — and want wireless, hands-free audio.
The NUBWO HW02 is built around one idea: keep spoken communication clean and effortless. The control box houses an enhanced Digital Signal sound card, which is what gives it that clear, natural, rich audio whether you're on a video call or just playing music in a busy workspace. The adjustable boom mic is designed to minimize background noise, so the person on the other end hears your voice rather than the office around you. Platforms like MS Teams, Skype and Zoom are all in scope.
Comfort is where this headset quietly wins. At 60 grams it's genuinely light, and the on-ear, circular earpieces are meant to stay put through all-day use and long calls. The inline controls let you adjust volume and mute the mic without touching your computer, and there's a mute indicator light so you always know whether you're live — a small detail that matters more than people expect. Connectivity is flexible in a very practical way: a 3.5mm plug goes straight into a phone or tablet, while the detachable USB inline controls handle PC and Mac calls. The 27mm dynamic drivers run 20 Hz–20 kHz at 32 ohm and 96 dB sensitivity, which is a sensible spec set for voice-first listening.
Who should buy it: office workers, call center staff, webinar hosts, students and anyone who spends hours on voice calls and wants something wired, predictable and light. It's also a smart pick if you're equipping a team — it comes in 1-pack, 5-pack and 10-pack options, and there's a 2-year manufacturer warranty. Who should skip it: if you want wireless freedom, immersive music with strong isolation, or active noise cancellation, this isn't the tool. There's no noise control here at all, and everything depends on a physical connection to your device.
The epekops AI is a different species of device entirely. It's a single-ear Bluetooth headset (model YYK-525) with a rotatable ear hook and a 180° mic handle, so you can flip it between ears and wear it for hours without pressure. The headline feature is AI translation: paired with the AI Translator app, the headset broadcasts live voice translations straight to your ear during in-person conversations — essentially a pocket interpreter. One-tap answer and hang-up plus auto-pairing keep the day-to-day mechanics simple, and voice assistant support means hands-free control while driving.
Audio hardware is surprisingly serious for a single-ear bud. A 14mm moving coil paired with a 10mm graphene diaphragm is designed to deliver HD voice and deep bass, while ENC (environmental noise cancellation) filters background noise so your voice cuts through in loud places. Battery life is the other standout: 10–12 hours on a single charge from the headset's 60mAh cell, extended to as much as 72 hours total via the 400mAh charging case, which has a power display so you're never guessing. Recharging is 1.5 hours for the headset, 2 hours for the case, and it supports both magnetic charging and direct Type-C.
Durability and fit are built for motion: IPX7 waterproofing handles rain, sweat and workouts, and the ABS+PC body keeps the total weight at 83g for headset plus case. Bluetooth 6.1 covers iOS, Android, PC and basically anything Bluetooth-capable. Who should buy it: drivers, truckers, delivery and field workers, travelers, gym-goers, and anyone who regularly communicates across languages or wants hands-free calling and voice assistant access. Who should skip it: if you want stereo music, a full over-ear or on-ear fit, or a wired connection with zero charging involved, this isn't it. There's no headphone jack, and the translation feature is tied to the companion app.
Side-by-Side: Which Should You Choose?
• Best for wired reliability and zero charging → NUBWO HW02 (USB + 3.5mm, no battery to manage).
• Best for wireless freedom and all-day battery → epekops AI (12h per charge, up to 72h with the case).
• Best for driving, trucking and hands-free use → epekops AI (one-tap call control, voice assistant, single-ear fit).
• Best for live translation and multilingual conversation → epekops AI (AI Translator app broadcasting translations to your ear).
• Best for all-day wear comfort → NUBWO HW02 for desk sessions (60g on-ear), epekops AI for movement (rotatable hook, "barely-there" single-ear fit).
• Best for rain, sweat and workouts → epekops AI (IPX7 waterproof; the NUBWO is a desktop-oriented wired headset).
• Best for equipping a team → NUBWO HW02 (available in 1-pack, 5-pack and 10-pack options).
In my opinion, these two barely compete — they solve different problems. If your day is built around calls at a desk, I'd buy the NUBWO HW02: it's light, wired, instantly usable, and its mic and sound card are clearly aimed at exactly that job. If your day happens in a car, on a job site, or across two languages, I'd buy the epekops AI: the wireless freedom, ENC mic, IPX7 build and translator app are worth far more to you than a wired headset could ever be. Decide which of those two days sounds like yours, and the choice makes itself. Either way, check the current price on Amazon before you commit.
The NUBWO HW02, in my view. It's explicitly built for those platforms with an adjustable boom mic and an enhanced Digital Signal sound card, and the wired USB connection keeps things stable. The epekops AI works for calls too, but it's a single-ear Bluetooth design aimed more at mobile, hands-free use.
Yes — the product pairs with an AI Translator app that broadcasts live voice translations to your ear during in-person conversations. It's designed as a real-time interpreter tool, though you do need the app and a paired phone to use it.
The epekops AI, by a wide margin — it's wireless with 10–12 hours per charge and up to 72 hours using the 400mAh charging case. The NUBWO HW02 has no battery at all because it's wired, so it simply draws power from your device.
Both are built for long sessions, just differently. The NUBWO HW02 is only 60 grams and designed for all-day on-ear comfort during calls. The epekops AI uses a 360° rotatable hook and 180° mic handle for a light single-ear fit, with the charging case covering you through the day.
