Yes. Same quality, same volume.
While we're on the subject of sound quality, I use Poweramp as my preferred music player.
https://play.google.com/store/apps/details?id=com.maxmpz.audioplayer&hl=en It has a really great equalizer built in, with customizable presets that can be associated with either the stereo speakers, or a headset, or a bluetooth device, or some combination. There are probably other music players out there that have a descent equalizer, but the point is that there's some room for improvement over the stock sound.
I chose to boost some of the lower frequencies and turn down the midrange. The end result is a less "tinny" and warmer sound. In a sense, the device sounds like it's larger than it is.
