A good choice for active people, Bass-addicts will be extremely pleased by the amount of oomph offered. They also offer superthumpy and encompassing bass. The deepness of the low-end is truly stunning for earphones of this size. [CNet USA]

The Endorphins stay in place and I have yet to have them pop out while running. I REALLY like the Endorphins and plan to use them quite a lot. [ZDNet]

The sound quality was awesome with nice deep bass and adequate highs and lows, perfect for listening to upbeat music while you work out. [BuyMeAniPhone.com]

They sound phenomenal. JayBird throws caution to the wind, cranks the bass ratio up about as high they possibly can, and are apparently willing to go ahead and accept the fact that anyone who does not care for a large heaping of bass is not going to be interested in their product. With that big of a bass sound coming from earbuds, you would expect there to be a metaphorical crack in the audio architecture once you crank up the volume even a little, but that is not the case. The bass sounds brilliant at any volume, as does the treble. [Beatweek Magazine]
