Phone is not charged
If the smart phone being used is not charged enough it will continue to turn itself off. When the phone was purchased it should've come with a micro USB charger. If you do not have one, you can easily purchase one from any grocery or electronic store.

If the phone continues to freeze the phone may just need to be restarted. This is a common flaw with even the most recent smart phones.

No sound when using headphones

The headphones may be broken
The headphones used may be broken in some way. Try buying a replacement pair at any grocery or electronics store.
The phone may have water damage
Firstly, remove as many components of the phone as possible (Battery, SIM card, back cover etc.), because the water will corrode parts and boards if not taken care of quickly. If the phone has water damage that isn't too severe, placing it in a bag of rice or silica gel should absorb the water from the phone; however, if the phone has been submerged or exposed to any significant amounts of water, it is always a good idea to have it disassembled and cleaned to prevent corrosion.

If the previous steps are taken and there is still no sound when using headphones, the headphone jack itself may need to be replaced.
