BS1 has a phenomenal tuning until the sub bass, but if you weren't opposed to bumping the bass by like 2-4db wow what a threat that earbud is, I can only fault one little peak at 4khz (only because the v20/30 is bright) and other than that its wonderfully smooth and has more detail than almost all the $100 earbuds, infact its got more detail than the bk in some places.I agree - I guess the tension of the cable is key to wearing them with no adjustments.....it will be interesting to hear your take on EB2 compared to Ling for comfort!
....BS1 were another "almost" buy - would have loved to have heard jazz etc on them - but the heavy/fatiguing cable seemed like a deal-breaker!
Waiting to find a 15mm driver compatible shell to transplant the driver, make a lighter copper and silver plated cable for it and ill use it daily.
