If you want rugged, sweat-proof earbuds for workouts and small ear canals, choose Xmenha TWS True; if you need a travel companion that translates 165 languages and runs for days, choose Rulbovs NE70. These two look similar on the shelf — both are wireless earbuds with a charging case and touch controls — but they are built for completely different jobs. One is a gym-first audio device. The other is a pocket interpreter. Here's how I'd decide between them.
• Xmenha TWS True — biggest strength: IPX6 waterproofing on both the buds and the case, plus a genuinely tiny, lightweight build (18.14 g total) aimed at small ear canals.
• Xmenha TWS True — biggest trade-off: No translation features, no screen, and an on-earbud battery that runs about 4–5 hours before you need the case.
• Rulbovs NE70 — biggest strength: A 1.3-inch LCD touch screen built into the charging case that controls 165-language translation, including offline packs, with under-1-second latency claimed.
• Rulbovs NE70 — biggest trade-off: It's a niche tool first and a music earbud second — the design and feature set revolve around translation, not workouts.
• Who Xmenha TWS True is for: Runners, gym-goers, and anyone with small ears who wants simple, water-resistant earbuds with a long case-backed runtime.
• Who Rulbovs NE70 is for: Travelers, international business users, and anyone who regularly needs to talk across a language barrier.
The Xmenha TWS True is a straightforward pair of true wireless earbuds, and it doesn't pretend to be anything else. The headline feature is durability: an IPX6 waterproof rating applies to both the earbuds and the charging case, which is more than you get from a lot of budget earbuds where only the buds get a rating. In practice that means sudden rain and heavy sweat are part of the design brief, not an accident waiting to happen. If you run outdoors, lift, or cycle, that matters more than any spec sheet number.
The second thing that stands out is the size story. These are described as mini, "invisible" earbuds designed for small ear canals, and the whole package weighs about 18.14 g. For people who find standard earbuds uncomfortable or prone to falling out, that focus on a rounded-tip, compact in-ear shape is the real reason to pick these. You also get Bluetooth 5.3 for a stable connection at roughly 10 meters, dual microphones with ambient noise cancellation for calls, and touch controls for volume, calls, and voice assistants.
Battery life is where you need to set expectations. The buds themselves play about 4–5 hours per charge, and the 800 mAh case stretches that to a claimed 45 hours total, with a full recharge taking around 2 hours. There's a digital LED display showing power from 1% to 100%, and the case doubles as an emergency charger for your phone. Who should skip it? Anyone who needs language translation, a screen on the case, or premium audio tuning — this is a practical everyday and workout earbud, not a specialist device.
The Rulbovs NE70 is a different animal entirely. Its defining feature is the 1.3-inch full-color LCD touch screen built into the charging case — you select languages, switch translation modes, and check battery without pulling out your phone. That's the whole philosophy of this product: keep the phone in your pocket and control everything from the case. It supports 165 languages, with 8 major languages (English, Spanish, French, Japanese, Chinese, and more) available as free offline packs you download once and use without Wi-Fi or cellular data.
Translation speed is pitched at under one second of latency, backed by dual-mic beamforming and environmental noise cancellation so your voice is picked up in airports and restaurants. There are 9 translation modes, from face-to-face AI conversation to binaural earbud-and-phone collaboration for groups, machine-assisted translation for complex sentences, and image-based text translation for menus and signs. That's a genuinely wide feature set for a single pair of earbuds.
Battery is travel-grade: 6 hours of continuous translation, 8 hours of music at 50% volume, and a case that holds 4 full recharges for 60+ hours total, with USB-C charging the case in about 1.5 hours. The average battery life is listed at 4.5 hours. Who should skip it? If your main goal is gym audio, the NE70's feature weight and on-ear design are overkill — you'd be paying for translation you'll never use. It's aimed at adults, and the warranty description is listed as "no," so factor that in.
• Best for workouts and sweat → Xmenha TWS True. The IPX6 rating covers both earbuds and case.
• Best for travel and language barriers → Rulbovs NE70. 165 languages, 8 offline, controlled from the case screen.
• Best for small ears → Xmenha TWS True. It's explicitly designed for small ear canals and weighs around 18.14 g.
• Best for long trips away from a charger → Rulbovs NE70. 60+ hours total, versus 45 hours claimed for the Xmenha.
• Best for fast top-ups → Rulbovs NE70. The case charges in 1.5 hours versus 2 hours for the Xmenha.
• Best for phone-free control → Rulbovs NE70. The LCD touch screen handles languages and modes without your phone.
• Best for simple everyday listening → Xmenha TWS True. Bluetooth 5.3, touch controls, and an emergency phone-charging case.
• Best for charging your phone in a pinch → Xmenha TWS True. The 800 mAh case doubles as an emergency power bank.
In my opinion, these aren't really competitors — they're two different tools that happen to share a form factor. If you're buying for fitness, comfort in small ears, and water resistance, I'd buy the Xmenha TWS True; it does the core job without distraction. If your problem is talking to people in another language, I'd buy the Rulbovs NE70 without hesitation, because nothing about the Xmenha addresses that need. Match the earbud to your actual daily life, not to the spec that sounds most impressive.
Only if you need translation. The NE70's value is its 165-language support and LCD case; for plain music and workouts, the Xmenha is the more sensible pick. Check the current price on Amazon to compare value for your own use case.
The NE70 claims 60+ hours total with its case versus up to 45 hours for the Xmenha. Per charge, the NE70 lists 6 hours of translation or 8 hours of music, while the Xmenha lists 4–5 hours per bud charge.
Yes — both the earbuds and the case carry an IPX6 waterproof rating, which is designed to handle sweat and sudden rain during exercise. That's the Xmenha's strongest argument for gym and outdoor use.
Yes. Eight major languages come with free offline translation packs you download once, so you can translate without Wi-Fi, cellular data, or roaming charges. The remaining languages in the 165-language set work through the companion app.
