No complaints equals a boring review but a good product. A well-balanced signature that will suit both, bass-heads and normal people. Punchy enough for pop, subby enough for hip-hop and warm enough for a fleshy rock track. And given how clean and detailed the WI-XB400 is, the sound profile is suitable for acoustic genres as well. Add to that some decent call clarity, long battery life, and you’ve got a solid pair of wireless earbuds for your daily commute. The price isn’t crazy either.

They're extremely portable and they're stable enough for most sports. Breathability shouldn't be an issue, as they're earbuds, and the in-line remote is easy to use, though it can be slightly annoying, as it tends to bounce around a lot during heavy movements.

The sound feels muted in the midrange and some parts of the treble, whereas the bass stays fairly balanced and controlled.
