The quality is good but the connector sucks...

Instead of a separate Mic jack and a clean, 3 pole audio out jack; the tablet combines the two with a proprietary, 4 pole A/V jack.
Getting clean audio to a standard 3.5 audio in jack found in cars and stereo equipment has been problematic.

It would help if Nokia provided such a patch cord though.

BTW, it's not the equipment that limits audio quality. MP3's @ even 192kHz leave something to be desired... IMHO
