Persej, no idea. NO uses the Windows Media Player, so we're probably stuck with even more delays (the video you posted says it used to be half a second, but that nowadays it is "much better").Can we use this with NO?
As DBZ points out above, it takes our brain another eternity (300ms! I thought it was shorter than that) so we might as well forget about latency issues. What I would like to see in a future NO soundwise is a better quality. FLAC or WAV encoded from a direct analog or CD source (NOT from an MP3!). Don't use the speaker/HP output; use the Line-out or a USB DAC, into a cross-feed circuit and lastly a suitable headphone amp. There's an instructable out there to DIY the cross-feed: Cheap Acoustic Simulator (Crossfeed) for Headphones
As a result of all this, after a session I would expect to feel relaxed but not tired with sometimes a slight headache.
