2x Phantom I Gold Glossy White purchased in January 2017:
J48P****4U06 (Quite warm to the touch on their backs, 24/7, playing music or not)
Replaced with 2x Phantom Gold I Matte White, arrived today:
U36A****4U20 (No discernible heat anywhere)
3 weeks without them was painful.
All is good now! 
(The old ones sounded great, but didn´t always show when trying to stream to them.)
