Foster Electronics (Fostex' parent company) have quietly been leading closed back headphone design for decades. The Sony R10, Denon D2000/5000/7000 were OEMs of Foster's Biodynamic transducer. More recently, ZMF, Mr. Speakers etc. have made a small cottage industry out of modding the Fostex T50RP into a new generation of planar magnetic headphones.
These TH900 represent Fostex' own take on the top of the line in closed back headphones. These feature a skull shuddering 1.5 Tesla of magnetic flux density, compared to ~1 Tesla in the TH6xx and THX00 as well as the modern OEM variants from E-Mu etc.
The headphone is beautifully crafted, featuring Urushi lacquer cups (mesmerizing!), all hand made in Japan. The packaging and product presentation is luxurious, including a glamour brochure like that included with a new car. . . the nice Fostex wooden stand to display your treasure is also much appreciated.
The sound profile on these is not neutral. I disagree with Fostex' description of these as a reference headphone - these are a STATEMENT headphone. Their aim is not accuracy, but curation, offering you a luxuriously selected spectrum on a platter. The V profile frequency response on these is wild, the bass is amazing but also the large cup size and detailed highs combine for an enormous soundstage for closed backs. I also have the TR-X00 Ebony from Massdrop, and although wonderful in their own right, can attest that the 1 Tesla variant simply can't quite muster the impressive force the TH900 brings to your ears.
I own many top tier headphones (electrostats, planar mags, balanced armature as well as an army of high impedance german dynamics). These are not the most accurate headphones I own, but they may be the most FUN, the most joyous. They have made me late for work because I can't help but finish up listening to an album on them. Re-listening to my collection with these is like meeting an old friend I haven't seen in years, but somehow noticing something new about them immediately. A prominent YouTube reviewer joked that he got excited even about listening to 'The Aladin soundtrack' on them - lolz aside, I completely agree - I look for excuses to try these everywhere I can.
Praise aside, there are some downs. The cable, thankfully replaceable in the MK2, is cumbersome and long. It kinks up more like a garden hose than a headphone cable. Also, despite being closed back, these do not isolate particularly well. You can hear the room around you somewhat still, and expect that others will be able to make out what you are listening to as well - more appropriate for the living room than the office.
After having listened to these for about a month, I may like them even more than I did initially (and I liked them right away). Ironically, they were my first Fostex pair, but they definitely will not be my last. An absolute joyous headphone that celebrates Foster's rich history in audio.
