If you want a sweatproof in-ear bud with active noise cancellation and a gaming mode, choose RED STAR TEC T-90; if you need all-day open-ear comfort with a huge 40-hour total playtime and a built-in translation feature, choose MINISO X15PRO. Those two sentences capture the whole decision. One is a sealed, focused, bass-forward workout bud. The other is an open, weightless, wear-it-all-day companion. Both are sweatproof, but they solve sweat in completely different ways.
• RED STAR TEC T-90 — biggest strength: In-ear fit with Active Noise Cancellation, IPX6 sweatproofing and a dedicated low-latency Gaming Mode. It's the more immersive, more feature-dense listening tool.
• RED STAR TEC T-90 — biggest trade-off: Shorter battery life at around 6 hours per charge (1.5-hour charge time), and the sealed in-ear design blocks out your surroundings — which is great for focus and bad for traffic awareness.
• MINISO X15PRO — biggest strength: Open-ear earhook design that never plugs your ear canal, plus up to 40 hours of total playback with the charging case and a 165-language translation feature via app.
• MINISO X15PRO — biggest trade-off: IPX5 protection (fine for sweat and splashes, less sealed than IPX6) and an open-ear shape that inherently lets ambient noise in — no active noise cancellation here.
• Pick RED STAR TEC T-90 if you want noise cancelling, deep bass and a secure sealed fit for gym sessions and gaming.
• Pick MINISO X15PRO if you want invisible-feeling buds you can wear for hours, long battery, and translation help while travelling.
The T-90 is built around immersion. It uses Environmental Noise Cancellation with built-in microphones to cut background noise, and it supports SBC/ANC codec playback for a bass-heavy sound signature. If you've ever tried to hear a podcast on a noisy train or a busy gym floor, you know why that matters. The dual-driver setup runs a 20 Hz–20,000 Hz frequency range, so it covers everything from low-end rumble to vocal detail.
The standout feature for active use is the split audio mode. Music Mode gives you deep bass; Gaming Mode drops latency so audio syncs with on-screen action. That's a rare thing at this tier — most budget buds make you choose between "fun sound" and "low lag," and the T-90 lets you switch on the fly. Touch controls handle calls, volume, media and even an AI assistant, so you're not digging for your phone mid-set.
Then there's the fit. It's an in-ear, rounded-tip design with S–L ear tips included, and it carries an IPX6 sweatproof rating — the higher of the two ratings in this comparison. IPX6 means it shrugs off heavy sweat and direct spray, which is exactly what you want from gym headphones. The package includes a charging case that supports wireless charging, plus a cable and spare tips.
Who should buy it: runners, lifters and gamers who want sealed, noise-cancelling sound and don't mind recharging every few hours. Who should skip it: anyone who needs to stay aware of traffic, coworkers or kids while wearing buds, and anyone who hates the plugged-ear feeling. If that's you, the open-ear design of the X15PRO is the better match. Check the current price on Amazon before deciding — the value math changes fast at this tier.
The X15PRO takes the opposite approach. It's an open-ear earhook bud, which means the driver sits outside your ear canal rather than inside it. Nothing gets plugged. You hear your music and the world around you at the same time. For cyclists, commuters and anyone who wears buds at a desk for eight hours, that's a genuine quality-of-life difference — no pressure, no ear fatigue, no "am I ignoring my surroundings?" anxiety.
Comfort is the headline. The body is ultra-light, the ergonomic hook grips your ear shape, and the design is explicitly aimed at not falling off during running and commuting. The enclosure is ABS plastic and the ear placement is open-ear, so there's nothing jammed into your canal.
Battery is the other big win: up to 40 hours of total playback with the charging case, plus fast charging. That's a travel-friendly number — a weekend trip without hunting for a wall outlet. Bluetooth 6.0 handles pairing, and the connection is rated stable with low latency for video and calls. Inside, a dynamic driver with 16-ohm impedance delivers the HiFi stereo tuning.
The X15PRO also does something the T-90 simply doesn't: two-way online translation across 165 languages through the dedicated SayMi app. It's positioned as a casual-conversation aid, not a professional interpreter tool, and it needs a network connection — no offline mode and no subscription fee. Treat it as a travel bonus, not the reason to buy.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → RED STAR TEC T-90. Active Noise Cancellation with built-in mics; the X15PRO has none.
• Best for long battery life → MINISO X15PRO. Up to 40 hours total with the case versus roughly 6 hours per charge on the T-90.
• Best for gym and heavy sweat → RED STAR TEC T-90. IPX6 beats IPX5, and the sealed in-ear fit stays put during intense movement.
• Best for all-day comfort → MINISO X15PRO. Open-ear, ultra-light, zero ear-canal pressure.
• Best for gaming → RED STAR TEC T-90. Dedicated Gaming Mode with ultra-low latency and audio sync.
• Best for travel and language help → MINISO X15PRO. 165-language app translation plus 40-hour playback.
• Best for staying aware of your surroundings → MINISO X15PRO. Open-ear design lets ambient sound through by default.
• Best for immersive bass → RED STAR TEC T-90. ANC codec support and a deep-bass Music Mode.
In my opinion, the MINISO X15PRO is the safer buy for most people, because the combination of open-ear comfort, up to 40 hours of total playback and IPX5 sweatproofing covers the widest range of daily situations — workouts, commutes, long workdays and travel. If your priority is noise cancelling sound, real bass and low-latency gaming, I'd take the RED STAR TEC T-90 instead; it's the more immersive tool, just with shorter battery life. Decide which of those two experiences you actually want, and the choice becomes obvious.
FAQ
what are sports earbuds
how to wear sports earbuds
In-ear models like the RED STAR TEC T-90 go into your ear canal with the correct tip size — S through L tips are included, so you can match your ear for a stable seal. Open-ear models like the MINISO X15PRO hook over the outside of your ear instead, leaving the canal open so you stay aware of your surroundings.
how to connect sports earbuds
Both are wireless Bluetooth buds with a 10-meter range. The T-90 pairs with iOS, Android and laptops over Bluetooth 5.3, while the X15PRO uses Bluetooth 6.0. In both cases you put the buds in pairing mode, select them in your device's Bluetooth menu, and they connect. The X15PRO's translation feature additionally needs the SayMi app and a network connection.
how to use sports earbuds
Use them the way the hardware is built: the T-90's touch controls handle calls, music, volume and AI assistant access, and you can switch between Music Mode for bass and Gaming Mode for low latency. The X15PRO is touch-controlled too, and its main daily use is long, comfortable listening plus casual two-way translation in 165 languages through the app.
