https://community.sony.no/t5/portable-audio/mdr-xb70bt-sound-deterioration/m-p/2280372#M3381 <P>Confused why when I 1st use these earbuds with my Samsung Galaxy S7 the sound is rich in bass and treble and powerful but after a while the sound becomes quieter with not much bass, treble or power. Have tried a couple of units and ran into the same problem. Sometimes factory resetting my phone temporarily fixes the problem.</P> Tue, 10 Jan 2017 16:39:57 GMT woodmj72 2017-01-10T16:39:57Z https://community.sony.no/t5/portable-audio/mdr-xb70bt-sound-deterioration/m-p/2280372#M3381 <P>Confused why when I 1st use these earbuds with my Samsung Galaxy S7 the sound is rich in bass and treble and powerful but after a while the sound becomes quieter with not much bass, treble or power.
