Metallic theme California Headphones, any opinions?

    finally, i got to see Tyll for real at CES 2012.
    It is my frist time to encounter a set of headphones with entire metalic ear cups. i wonder how well it performs. any reviews on this yet or in line with such genre?? 
  2. Armaegis
    Metallic earcups? The Sennheiser Amperior, NuForce HP-800, Pioneer HDJ-200 comes to mind. I'm sure there are plenty others. Cup vibration will be reduced slightly compared to, but resonance issues will still be the same as that's mostly a geometry thing. 
  3. JamesM
    when it comes to vibration issue, it reminds me of Fidelio S2 which allegedly claims its metal housing is meticulously engineered to reduce resonance and vibration. so is it really true that metallic shells have a genetic edge over others?
  4. Armaegis
    Yes, but just slightly (plastics can be quite rigid as well). Cup damping will make a bigger difference. 
  5. JamesM
    Cup damping? kindly elaborate on it please?
  6. Armaegis
    Cup damping is mostly filler in the cups, like cotton, fiberglass, felts, or acoustic foams. These all disperse reflections in the cup and affect the frequency response.
    The effects of cup damping will generally be far more noticeable than changing the cup or baffle material (assuming all geometries and weights are mostly the same).

    thanks for reminding me some basic principles in physics from college, 
    next time when i am on a mod job, i will definitely try them out.
    I was planning to buy those to use for a driver transplant...
