I recently bought myself a laptop for making music on the go. It's a Razer Blade 14" and it's great, but the on-board sound card is predictably crap - for example, when played through my headphones (which sound fine when plugged into my desktop), a 50Hz sine wave sounds more like a triangle wave. I'm thinking about getting an external USB sound card and was wondering if anyone has any recommendations. I won't be using any additional hardware so I don't need a proper audio interface with a bunch of different ins and outs, nor do I need anything particularly high-end. I'm considering one of these two.
Does anyone have any experience with this kind of thing? I'm running Windows 8 (likely to be upgraded to 10 in the near future).
