BeWare!
Of the 20pairs of standard Be7 I have in circulation at the moment, most users are on their 2nd pair, some are on their 3rd.
Most issues appear to relate to terminal receiver failure due to wax/moisture ingress. Some users also appear to cause alarmingly quick stress-hardening and failure of the microphone wire sheath. That’s in addition to the issues with the mic ports blocking.
Hopefully the MK2 Be will have these issues resolved. I’m pushing for a free upgrade for all my customers - if not the lot will be going back and they’ll get moved to Unitron Fuse.
My own Be9 experience (I’m on my second) is that they work OK for a while and then lose amplification. This unit has now gone the same way and has been back to GN and supposedly fixed.
They seem to still be able to create volume during the feedback calibration but just fail to make quiet sounds audible once the fault occurs.
So, my experience is they still sharpen up normal conversation suddenly my hearing threshold changes (quiet conversation, whispers, clicks, clocks ticking, quiet TV dialogue are all “lost”) once the fault occurs.
(the fault also signals a change in the sound of feedback - from a high pitch to a lower warble - and a sudden ability to use a mobile phone without causing a screech!)
I have found the mic filter responds well to careful use of a “rocket blower” (with the filter removed!) to unblock the 4 tiny ports.
On the plus side, the sound quality is extremely “clean” with both voice and music essentially unaffected by distortion of any kind.
Frustratingly close to a great solution!
What is the “Mark 2 Be” and is there any update on your solution?
