Four products
One acoustic target, four ways to hear it. Every unit is measured in our chamber before it leaves Singapore, and every part is available for a decade.
Kestrel One
40 mm beryllium driver, 32 Ω, 285 g. The pair we send to every mastering room that asks.
Kestrel Open
50 mm driver, 300 Ω, 340 g. Open-back and deliberately inefficient, for valve amplifiers.
Kestrel Studio
Folding closed-back pair for editing and travel, with the same driver as the Kestrel One.
Kestrel Amp
Class A/B, 2 × 2 W into 300 Ω, with a relay-switched attenuator and no digital stage.
Closed, and honest about it.
A closed-back headphone without the usual low-mid hump. The cup is machined from a single billet and lined with three densities of felt.
Every part is replaceable: pads, cable, headband, even the driver, which is held by four screws rather than glue. A repair in year eight costs a fraction of a new pair.
Numbers, as measured
Measured in our anechoic chamber at 1 m, averaged across three units from the current batch.
