Problem with headphone jack

I have an iPhone 6. Yesterday my headphones got caught while they were plugged in and the headphone jack bent while still plugged in. Since then, the headphone jack is behaving weirdly. I was able to have a phone call with hands-free perfectly fine. But playing music through in-ear headphones doesn't work - the sound is very low and only comes from the right (tried a few different ones). However, everything works with on-ear Bose headphones. Can anyone help?

Thanks!
