Don't do it. I was very unsatisfied with the sound on my Nexus 5 so I called Google. I got my replacement yesterday. After making a nandroid backup of my 1st phone and restoring it on my second, I can't believe the difference in the sound. I can now hear my ringtones and notifications. Youtube is loud and clear. I would recommend that anyone who got one of the early phones that has a volume issue like me get a replacement phone immediately.
