Was looking for a comparison so I've just checked it out and I don't think the ff3 would cut it. Swapable cables? absolutely. already worth an extra 10€ xD I only have low low lowest end earbuds currently just to replace my broken ones. I also wear them against the wind (my ears are so broken). I fell for the ff5 instantly even without hearing anything. Going to order them within the day 🎶 I listen to music basically all day for writing and chores. It's my thinking juice. I can't wear my Marshall on-ears for that long. Thanks again, you really saved my day.
