When they worked, sounded great. All 5 times I used them!! Died sent them back. Got another pair and they won't synchronize with my phone. Tried several other phones. You get what you pay for!!! Got a set of Bose...twice the cost ; even better sound, much much longer battery life and they stand up to my sweaty workouts.
GeodHi Geod, I've sent an inquiry into your issue to the customer service team. You shouldn't have any issues connecting Evo X to your phone. If you haven't done so already, try draining the battery, fully recharge and pair again. You have to long press the power button to put Evo X in a pairing mode. -Peter
GeodBose has an awful freq response curve with scooped mids. I never had problem with mine syncing to five different devices over the year plus I have owned these. YMMV
