first off the sound sucks its tinny sounding bass is weak the fit is horrible there is no isolation i turned on the anc and everything got louder which was weird the tips they provide are all way to small you can hear every noise around you. The tune beams are cheaply made way to light just awful jbl been cutting corners and charging large dollars for them these buds are worth 50 dollars tops and that is pushing it i will never buy JBL ever again i called JBL support and they were rude and informed that i will have to buy 3rd party earbud tips so i said i am just going to return these garbage earbuds and buy a premium set
Purchased these for work besides PowerBeats Pro and Jabra Elite 5 , and I am impressed with how they fit. Not precise sound like Jabra but if you play with the equalizer a little bit they sound pretty good with strong bass. Finally, an app that works, you can on/off, and adjust everything. Good job JBL!
