Just like with their bass, the JLab Audio JBuds Air Executive’s excited sound signature gives them very inaccurate treble. The response is flat continuing from the high-mids into low-treble, but quickly rises, giving extra detail and presence to most instruments. The overemphasis persists into mid-treble, which gives these earbuds added brightness, but also makes them sound a bit harsh. Certain sounds, like cymbals or sibilants such as “S” or “T” sounds, can sound especially piercing. Not everyone hears sounds in these ranges the same way, though, so this may not be an issue for some people.
