Ever been in the middle of a workout when your earbuds decide to take a dive? Not with our Wireless Earbuds Sport.

as a brand loyalist i had high hopes for these from rulefiss, i thought they'd hum with quality but reality hit, the bass is strong which is great for my gaming sessions but the call quality is just okay not crystal clear, they do last a long time and the fit is secure no drops during workouts, but comfort wise after a while my ears hurt a bit, the touch controls work well but sometimes too sensitive, overall they're decent but not amazing, could be better for the price
- Pros: they stay connected well and the sound is full with deep bass, i like that they fit securely with the earhooks and are waterproof, the long battery life is a plus and charging is quick, the touch controls are responsive and easy to use :)
- Cons: i was fairly disappointed that the sound clarity isn't as good as i expected during calls, it could be wrong but they feel a bit bulky and not as comfortable for long sessions, the battery indicator isn't always accurate which is annoying
