How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want serious workout audio with active noise cancelling, a heart rate sensor and up to 45 hours of battery, choose Amazon Renewed Beats Powerbeats Pro; if you need a pocket interpreter that translates two-way in real time across 163 languages, choose IAMJOY Language Translation Earbuds. These two products only look like competitors because both sit in your ears. In reality they solve completely different problems, and once you see which problem is yours, the decision makes itself.
• Amazon Renewed Beats Powerbeats Pro — biggest strength: training-focused design with earhooks, Active Noise Cancelling, IPX4 sweat and water resistance, a real-time heart rate monitor and up to 45 hours of total battery with the charging case.
• Amazon Renewed Beats Powerbeats Pro — biggest trade-off: it's a renewed unit rather than new, and it's built for sound and sport, not for translating conversations.
• IAMJOY Language Translation Earbuds — biggest strength: real-time two-way translation in 163 languages (78 languages plus 85 accents), with multiple interpretation modes and no subscription fee for translation.
• IAMJOY Language Translation Earbuds — biggest trade-off: open-ear clip-on design means less bass isolation and no active noise cancelling, and battery runs 3–4.5 hours per charge before you need the case.
• Who each pick is for: the Beats for runners, lifters and gym regulars who want immersive sound and workout data; the IAMJOY for travelers, students and anyone who talks across languages daily.
The Powerbeats Pro 2 is a workout headphone first and a listening headphone second, and everything in the design says so. The earhook shape is engineered to stay locked in while you move, and the spec sheet notes over 1,500 hours of athlete testing behind that fit. You get the company's most advanced Active Noise Cancelling plus a Transparency mode when you'd rather hear traffic or a training partner. An IPX4 rating means rain, snow and heavy sweat are part of the job description, not a risk.
The feature that stands out most to me is the heart rate monitor, which pulses over 100 times per second and reads your pulse in real time — no chest strap required. Inside, the Apple H2 chip drives up to 45 hours of battery with the charging case, and the case itself is 33% smaller than the previous generation and supports wireless Qi charging for the first time. Adaptive EQ measures what you're hearing and adjusts frequencies on the fly, and Personalized Spatial Audio with dynamic head tracking adds a sense of stage around you. iPhone users get one-touch pairing, automatic switching, Audio Sharing, hands-free Siri and Find My. Android users aren't left out: the Beats App unlocks one-touch pairing, heart rate monitoring, customizable controls, battery widgets and Locate My Beats.
Buy it if you train hard, want noise cancelling that actually quiets a gym, and care about battery life measured in days rather than hours. Skip it if your main need is talking to people in other languages — nothing here translates speech — or if you prefer an open-ear fit that lets the world in. Note too that this is a Renewed Premium listing, so you're buying a refurbished unit backed by a 1-year warranty description rather than a brand-new box.
The IAMJOY CT28 is a translation device that happens to be shaped like earbuds. Its core claim is real-time, two-way translation across 163 languages, covering 78 languages and 85 accents, with accuracy stated at 90%+ and a response time of about 0.5 seconds. Importantly, the companion app carries no subscription fee — translation is lifetime free, which matters because a lot of translation gadgets quietly meter their best features. The language list spans English, Spanish, Chinese, Vietnamese, Arabic, French, Korean, Russian, Portuguese, Japanese, German, Thai, Italian and many more.
What makes it more than a one-trick translator is the mode list: AI Chat mode, Free Talk mode, Translation Machine mode, Headphones+Phone mode, Voice Notes mode that turns recordings into meeting-note text, Photo Translation mode that reads and translates text in images, Audio and Video Translation mode, and Simultaneous Interpretation mode. For a student in a lecture, a business traveler in a meeting, or a tourist pointing a phone at a menu, those modes cover very different situations with one device. It's also a normal set of earbuds: music playback through a large dynamic driver, clear phone calls, and Bluetooth 5.4 for stable connectivity.
The physical design is the other half of the story. These are open-ear clip-on earbuds with a C-bridge made from skin-friendly silicone and a high-resilience ring. Each earbud weighs just 5.1 grams, so they rest on the ear rather than plugging the canal, and you stay aware of your surroundings while listening. Battery runs 3–4.5 hours of continuous listening or live translation, and the Type-C fast-charging case extends that to a full day.
Buy it if you regularly cross language barriers, want translation without a subscription, or dislike in-ear pressure and prefer an open fit. Skip it if you want active noise cancelling, deep isolation for the gym, or a heart rate sensor — none of that is here. The warranty description is also short, at 3 months, so factor that into how you plan to use it.
• Best for battery life → Amazon Renewed Beats Powerbeats Pro. Up to 45 hours with the case versus 3–4.5 hours per charge on the IAMJOY.
• Best for workouts and sport → Amazon Renewed Beats Powerbeats Pro. Earhook fit, IPX4 sweat and water resistance, and the ANC/Transparency pairing are built for training.
• Best for fitness tracking → Amazon Renewed Beats Powerbeats Pro. The heart rate monitor reads your pulse in real time at over 100 pulses per second.
• Best for travel across languages → IAMJOY Language Translation Earbuds. 163 languages, 0.5-second responses and multiple interpretation modes.
• Best for comfort over long sessions → IAMJOY Language Translation Earbuds, in my opinion. At 5.1 grams per earbud with a silicone clip-on bridge, there's no canal pressure and no ear fatigue.
• Best for staying aware of your surroundings → IAMJOY Language Translation Earbuds. Open-ear design lets ambient sound in; the Beats give you the opposite, deliberate isolation.
• Best for study and meetings → IAMJOY Language Translation Earbuds. Voice Notes mode converts recordings to text and Photo Translation handles printed material.
• Best for iPhone or Android ecosystem extras → Amazon Renewed Beats Powerbeats Pro. One-touch pairing, Audio Sharing, Find My on Apple, and the Beats App on Android.
If I had to pick one, I'd buy the Amazon Renewed Beats Powerbeats Pro. In my opinion it's the more complete product for daily life: it does music, calls, noise cancelling, workout tracking and multi-day battery, and it fits two ecosystems without fuss. The IAMJOY is genuinely impressive at one specialized job — real-time translation in 163 languages with no subscription — but that job is narrow. Buy the Beats if you want headphones; buy the IAMJOY if you want a translator. If you truly do both, they don't overlap enough to be substitutes, so check the current price on Amazon and decide which problem costs you more.
They're renewed units rather than brand-new ones, but the listing is Renewed Premium and carries a 1-year warranty description. Functionally you get the same Powerbeats Pro 2 features: ANC, heart rate monitoring, IPX4, the H2 chip and the wireless charging case.
The specs describe online language translation and app-based modes, so plan on a connection for live translation. The 163-language support, 0.5-second response time and free lifetime translation all run through the companion app rather than the earbuds alone.
No. The Powerbeats Pro 2 is an audio and fitness product — noise cancelling, spatial audio, heart rate. There's no translation feature anywhere in its design, so it can't stand in for the IAMJOY.
For quiet, the Beats win: Active Noise Cancelling and up to 45 hours with the case make a long-haul flight easy. For talking to people at the destination, the IAMJOY is the one you'll actually need — just expect 3–4.5 hours per charge, topped up through the Type-C case.
