Fostex build TH610 in beautiful matte finished black walnut housings, a plain finish that still reeks of sophistication, finesse and engagement. Do judge this book by its cover, at the sound quality awaiting you.
TH610's 50mm driver is made of Biodyna. Stiff and lightweight as a diaphragm but also promising excellent damping, this biocellulose material allows Fostex to keep the large driver under control at all times even as frequencies rise, averting any harsh intermodulation due to cone modal break-up.
Notes start and stop on a dime, transients properly defined without smear or bleed – clearly a low-distortion affair for even-handed and natural music reproduction throughout. A one-tesla magnet keeps TH610's driver locked down and under control at all times.
Fostex have a mid-tier headphone that makes claim to get you all the way, carving a space for itself in an ever-more competitive market with its closed-back isolation by design and easy-to-drive nature from humble amplification. Hi-Fi World say TH610 is among the best.
