PFRV1 | Personal Field Speaker Headphones | Sony | SonyStyle USA
I was doing a little research today about permendur for use in magnetic circutis. At the company I work for, our highest end speaker drivers use all permendur magnetic circuits in a field coil configuration. The sound of all permendur is completely bonkers. Unbeleivable (and incredibly expensive, but worth it for the money...). Truely though, there are no words to describe it. Sorry for the ones I already spent. Ill let you read up on it, but even that won't do much good. Permendur is VERY special stuff. the fabric of musical existence perhaps. must be experienced properly to be understood.
In either case, I noticed these Sony headphones. This is a Sony Personal Field Speaker Headphone for 400 bucks. It claims a Neodynium magnet and all permender magnetic circuit. If what happens to the sound given the permendur is what I think will happen, then this might be worth looking into? The sound of Neodynium I am not a particular fan of (yet). No emotional connection to it like I share for alnico. Perhaps I have not heard the right implimentation of it? Truely, I do not want to come across like some seasoned and infallable "expert" on this topic. I have not heard very many neodynium magnetic circuits in the first place.
Of course also we make it back to the sonys where we have no guarantee of what the shape, thickness, or grade of permendur is... if not properly designed, the circuit might not exhibit any real world "torque" characteristics and only look good on paper....the proof is in the hearing.
Basically, this seems like a tiny loudspeaker that sits on your head. kinda cool?
lemme know anyone if you have come across this, thanks in advance!
