Well,
there are serious issues with respect to working with beryllium -
notably when the metal is being machined - producing beryllium
particulate matter.
In fact, the issue is serious enough that several governments
and universities around the world have issued advisory
papers, bulletins, guidance and the like.
These include, but are not limited to:
The US Dept of Labor - Occupational Health
and Safety Administration
https://www.osha.gov/SLTC/beryllium/
the eu's 8 element Beryllium Safety Model (Belgium)
http://beryllium.eu/product-stewardship/beryllium-safety-model-2/
Fermilab (USA)
https://www-esh.fnal.gov/CourseHandout_Mat/BeVideo1.pdf
MIT (USA)
Beryllium Policy and Procedures

the Ontario Ministry of Labour

iter (France)

Los Alamos National Laboratory (USA)

Health and Safety Executive (UK)

Generally, the essential hazards lie with breathing or touching beryllium salts,
breathing any "dust" generated in machining or otherwise "working" the metal itself,
and even coming into contact with the metal is considered potentially hazardous,
doing so is to be avoided.
Just posting this to hopefully shed some extra light on OP's question,
and hoping as well that it might provide some potentially useful information
on the subject to the Head-Fi community.
It does seem interesting that Focal has not responded at all to 6 emails,
although there could be many legitimate reasons why OP has not
yet received a response.
If I might, I would certainly suggest phone contact with Focal regarding
the emails which have evidently gone unanswered to date.
Cheers,
