Trendwoo Runner X3 Wireless Bluetooth 4.0 Stereo Sports Earphones are among the very best wireless Bluetooth earbuds for runners. Their low weight and high-fidelity sound quality make them easily recommendable for almost anybody. The only real exception are people with very large ears.

Trendwoo Runner X3 are designed specifically for runners, which is reflected in their overall construction and designed.


Running is one of the most demanding activities when it comes to how securely earbuds can stay in ears. When people run, they essentially create a large quantity of small shocks in quick successions. These shocks can slowly but surely shake earbuds out or just dramatically reduce sound quality due to poor fit.

Trendwoo Runner X3 intelligently distribute the bulk of the weight away from earbuds to prevent them from falling out of your ears. Included ear tips are also slightly more oval than the ones that you regularly get with new earphones. These small design improvements compound into what can only be described as a great fit and comfort.

Build quality

Runner X3 are sweat proof and seem to be built well enough to survive everyday use. The cable deserves a special praise as it’s very hard to tangle and twist, and it always comes back to its regular shape.

The most distinct aspect of these earbuds is their extraordinary small size, which makes them almost disappear in the ear. Only part that is visible are the robust stress relievers.

The built-in volume controller is located approximately on the same level as your jaw would be, and it’s easily controlled without looking. All buttons have slightly raised symbols to give users a useful tactile feedback to let them know for sure that the button has been pressed. Since they are spaced far apart from each other, it’s easy to use them even with gloves on.

Sound quality

These Bluetooth earbuds have a very pleasant warm sound signature. This makes you come back for more as music tends to feel like a soft blanket over your ears. The bass is not as boomy as we would like it to be for our gym workouts, but these are designed for runners after all.

The Trendwoo Runner X3 Wireless Bluetooth 4.0 Stereo Sports Earphones are fantastic with all music genres that heavily rely on prominent vocals. This is because the mids are very prominent and stand out from the rest of the frequency range.

Isolation is solid, but not overly impressive. Sounds around you will be much less disturbing, but you will still be able to make out loud conversations.

What is in the box?

You will get a total of 3 pairs of replaceable ear tips, one USB cable, a user manual, and Trendwoo Runner X3 Bluetooth earbuds themselves.
