IPhone 5 versus iPod Touch 5th generation SOUND QUALITY?

I was wondering if the sound (audio) quality of the iPod Touch 5th generation is the exact same as the iPhone 5's.

Or is one's audio quality (for music) any better than the other?

Does anyone know the answer to this question? I couldn't find a direct answer on Google.

Also in general how good is the sound quality of the iPod Touch 5th generation/ iPhone 5? Has the sound quality improved at all over previous models?

The iPhone 5 has dual stereo speakers and the iPod Touch has just one speaker. The iPhone has better sound than all the previous models from before.
