Default Studio Condenser Microphone issue?

I own a behringer C1 studio condenser, I also own a Phantom power supply.

I have a XLR female that plugs into the Microphone with a male ending that goes into the phantom power supply.

I also have a Female XLR to a quarter jack cable, the Female XLR goes into the other end of the phantom power supply and the quarter jack I put a 3.5 mm jack adapter on the end to plug into my computer.

It picks up the mic and the sound.BUT the playback of the recorded sound is very quiet and makes my voice sound high pitched.

If someone would PLEASE help me rectify this, I would be very very grateful!

I Need this working to help push my Youtube channel Android Insanity increase in quality.

Top reliable phones I have had: HTC One. LG G2, Nexus 4, Note 2, Nokia 5800, Motorola RAZR V3X, Motorola RAZR i, Nexus 5 Had many more, but these devices were the best IMO.

Current Phone: HTC One M8
