Hover
Kestrel makes closed-back listening instruments in a small Rotterdam workshop. The first series uses a 40 mm biocellulose driver set inside a machined aluminium earcup, with memory-foam pads wrapped in vegetable-tanned lambskin. The headband is a single strip of spring steel, shaped by hand and finished with full-grain leather. No logo is moulded into the plastic; the only mark is a small serial number etched inside the yoke.
These are made for long listening sessions at a desk, on a train, or in a dim room with an album played end to end. The detachable cable system accepts three lengths, each terminated in the same locking 2.5 mm connector. The earcups rotate flat for travel, and the included hemp case uses no foam.
Orders ship within five business days from the Netherlands, in plastic-free packaging. We offer a 30-day return window for unused items in original condition; shipping costs for returns are covered if there is a manufacturing defect. Custom-engraved or made-to-measure orders are final sale.
