Some years ago I came across a technical article (that I can no longer find) claiming that the original BL5 microphone calibration had a notional life of about 200 uses, but that owners often liked to demonstrate the calibration to visitors to the extent that the mechanisms often suffered premature failure. Apparently B&O thought that calibration would only ever take place a handful of times.
Worst thing I ever did: calibrate the BL5. They were never the same again! When they first shipped they sounded fantastic, but as my (large) apartment has wooden flooring and sash windows, decided to calibrate after 2 months. It was almost as if someone removed the bass overnight. Incredible difference.
BL5s sound amazing when they aren't calibrated, but not sure I'd recommend them. I kept mine for 6 months, someone came along and offered a decent price and I had no hesitation selling them on. Great decision.
The idea of owning BL5 is more fantastical than actually using them. And unless you have a HUGE space and no neighbours, what's the point? I had enough complaints from my BL2.
