There is an illumination mode in the Music Centre App > Setting on your XB40 > Illumination > Lighting mode > Random Flash Off; is basically Rave, but without the strobes! Hope this helps as you said you thought it could do without the strobes!
is it true that when it hits 50% then it turns down the volume and as well saying you need to charge it , because thats very irritating . great review by the way , i am in doubt getting the sony or the jbl 3
If the battery is low it will automatically lower the volume,but if you turn of and turn on the device it will go back to full volume without charging?
