I've heard higher end strings in action and there's definitely a difference, even among equally skilled violinists, but these guys are definitely perfectly good, both in general and especially given the price differential. When I first got my violin and before I got it set up with a set of Wittner fine-tune pegs I accidentally snapped a couple of strings during tuning, which I had to do a lot of since the thing wouldn't stay in tune worth a darn. So, especially for a novice like myself or if you're tuning a lot because of slippage with regular pegs, these are nice because they get good sound without being so expensive you're going to get angry if one of them breaks or otherwise needs to be replaced.
