TRAUSI i27

The TRAUSI i27 wireless earbuds are a battery monster with 54 hours of total playtime, IPX7 waterproofing, and a secure ear-hook fit that's perfect for workouts. Sound quality is below average and the case feels cheap, but for budget buyers who prioritize durability and battery life over audio fidelity, these are a solid pick.

The i27's standout metric is battery life, and the numbers back it up. You get 6 hours from the earbuds themselves and 54 hours total with the case, which lands in the 92nd percentile of all wireless earbuds in our database. That's enough for a full week of workouts without touching a charger. The 10-minute quick charge adding 2 hours of playback is a nice touch for forgetful types, and the case supports Qi wireless charging alongside USB-C.

Connectivity is another bright spot. Bluetooth 5.4 with dual-channel transmission means pairing is fast and stable, and the claimed 15m range is decent for most situations. The ANC performance sits at 74th percentile, which is solid for budget earbuds. It won't compete with Sony or Bose flagships, but it takes the edge off gym noise and airplane hum. The microphone lands at 68th percentile, which is fine for calls but not exceptional. Sound quality is where things get rough. At 29th percentile, the audio output is below average for the category. The dynamic driver delivers clear mids and vocals, but bass is thin and the overall tuning lacks depth. There's no companion app for EQ adjustments, so what you hear is what you get.

Against the Sony WF-1000XM6 or Apple AirPods Pro 3rd Generation, the i27 doesn't compete on sound quality or ANC strength. Those flagships are in a completely different league for audio fidelity and noise cancellation. But they also cost several times more. The i27's real competition is the Soundcore P31i and EarFun Air Pro 4+. The EarFun Air Pro 4+ delivers noticeably better sound and a more premium build, while the Soundcore P31i offers a more balanced audio profile with a companion app for EQ tweaks. Where the i27 wins is battery life and the ear-hook design. If you've ever had earbuds fall out during a run, the i27's secure fit is a genuine advantage that the other two don't offer.

The Technics EAH-AZ100 is another step up in price and performance, with superior sound and ANC. But for someone who just wants reliable workout earbuds that won't die mid-session, the i27's 54-hour case battery and IPX7 rating make it a practical choice. The question is whether you can live with the mediocre audio.

The TRAUSI i27 sits in the budget earbud bracket, and for the money, the battery life alone is hard to argue with. You're getting 54 hours of total playtime, IPX7 waterproofing, and ANC in a package that costs a fraction of what premium brands charge. The trade-off is sound quality and build materials. The charging case feels cheap, and the audio output won't impress anyone who cares about music fidelity. If your priority is battery life and workout durability over audio performance, this is a strong value. If you want better sound, the Soundcore P31i or EarFun Air Pro 4+ offer more balanced audio at a slightly higher price.

The TRAUSI i27 is a budget-friendly pair of wireless earbuds with an ear-hook design, aimed squarely at runners, gym-goers, and anyone who's tired of earbuds falling out mid-workout. They pack Bluetooth 5.4, active noise cancellation, and an IPX7 waterproof rating into a package that weighs just 7g per bud. The charging case adds a hefty 54 hours of total battery life, which is one of the best numbers we've seen at this end of the market.

People searching for cheap workout earbuds with good battery life will find a lot to like here. The i27 hits 92nd percentile for battery and 92nd percentile for connectivity in our database, which means it punches way above its price class on the features that matter most for daily use. The 10-minute quick charge giving you 2 hours of playback is genuinely useful when you're heading out the door and realize you forgot to charge them.

But the sound quality tells a different story. At 29th percentile, it's one of the weaker performers we've tested in that department. The 140Ω impedance rating is unusual for wireless earbuds and hints at some compromises under the hood. If you're buying these for critical listening, you'll be disappointed. If you're buying them to survive sweaty workouts and long commutes, they make a lot more sense.

Skip the TRAUSI i27 if you care about audio quality or want a premium build. The 29th percentile sound performance means bass-heavy genres like hip-hop and EDM will sound thin, and there's no EQ app to compensate. If you're an audiophile or someone who listens to music critically, the Soundcore P31i or EarFun Air Pro 4+ are better choices at a similar price. Also skip these if you need reliable long-range Bluetooth, as several owners report the connection drops sooner than the claimed 15m. And if you're rough on your gear, the cheap-feeling charging case probably won't hold up to abuse.

Should you buy the TRAUSI i27? If you're a runner, gym-goer, or commuter who prioritizes battery life, waterproofing, and a secure fit over audio quality, yes. The 54-hour total battery life is genuinely excellent, the IPX7 rating means you don't have to baby them, and the ear-hook design keeps them in place during intense workouts. The quick charge feature is a lifesaver for forgetful people.

But if you care about how your music sounds, look elsewhere. The 29th percentile sound quality is a real weakness, and the lack of an EQ app means you can't fix it. The cheap-feeling case is another annoyance. For the same money or slightly more, the Soundcore P31i or EarFun Air Pro 4+ deliver better audio. The i27 is a battery and durability champ that happens to play music, not a music lover's earbud.
