It seems to me there might likely be a 3.5mm audio jack on U according to the pic. Just look at the left side of the middle port.

HTC U “Ocean” to ditch headphone jack, gain water resistancehttps://www.slashgear.com/htc-u-ocean-to-ditch-headphone-jack-gain-water-resistance-18482388/3.5mm jack? Only in your dream!Even Samsung / LG has no guts to ditch 3.5mm jack. Only HTC has the guts to remove the 3.5mm jack, a suicidal decision.
Please refer to U Ultra.That spot is just a little tiny hole for the microphone.I don't think the 3.5mm audio jack will back on U.=================================更正一下.早上沒看仔細.原來提到的是中間那個大孔左邊連著一個圓孔.還是期待一下那裡會有什麼好了.
