StarksAdapters don't effect sound quality. The Q701 is terminated in a 3.5mm connection and comes with an adapter, so it doesn't really matter. If you have more headphones with 1/4'' jacks the desktop version might be more convenient, but if it's your only good headphone, the standard 3.5mm version will work just fine.
TylerJ.ChiltonThanks for the quick reply. I realize a lot of audiophile headphones only come in 1/4. So lets say I upgrade in the future, am I stuck if I get the 1/8" version? Do you include an adapter for the 1/8" model? I am just deciding which version to get now. Please help me decide. Thanks
