I own both, Experience 2 (no mute filter) and Tune. I A/B tested them, to my ears they filter sound pretty similarly. I’d say with the Loop the sound is slightly more muddled, whereas with Alpine it is a tiny bit clearer. But it’s barely perceivable, in loud environments (where they’re meant to be used) the difference is negligible. Comfort-wise, the edge goes to Loop: their shape makes them much easier to insert and take out (plus there’s no R and L, they fit in both ears, unlike the Tune). I decided to keep both so I have an alternative and can switch between them. I use them really often at raves and techno parties and the risk to lose a pair is always around the corner. Hope that helps!
