mine had a perfectly good grip at first. Then it started losing it overtime. First with angled plugs and now even with straight ones. Hope your 2.5mm works great.Just gotten my second hand four month old dpx1. So far, I must say it sounds pretty good (even with my ve monks which I'm using as my daily driver until my nobleb4 comes in). That said, I already knew this while getting it but, isn't the 3.5mm jack kind of loose compared to everything else? It's not that it's disconnecting or anything just that it just takes considerably less force to pull jacks out compared to other devices. Just would like a confirmation here that its a common thing.
My 3.5mm now gets interrupted/paused by any minute movement of the cable through the plug
