[BC] Robust headphones

[Mike McCarthy]

I love my Sony 7806's.  I can bridge them across a circuit and the 
audio produced is deafening if more than -10dBu/dbm.  They also fit 
tight to head and mask much external noise. Audio is VERY good to 
excellent. Any they're hard to feedback if used correctly.

The connector is a PIA to replace.  But doable.  If the cable breaks 
in the headset itself, send them back.  Sony does fix them and I've 
had a number repaired under warranty even when it had expired.
