Great sound and ability to customise sound and hear through on/off through Jabra App. No drop outs. I leave my phone on the other side of the gym (at least 15 - 20m away) and still no drop outs. Also these are comfortable to wear and stay in my ear and don't fall out when running, however if you are chewing/eating they do fall out eventually. Blocks out a good amount of ambient/outside noise even when on the areoplane. Works good with watching video too - no lag/delay in sound. Battery life is as advertised and mine last a whole week of workouts without recharging the case. I returned the stupid looking earpods for these and so glad I did.
