About the On1

The Thinksound On1 headphones are designed as professional studio monitors with a focus on accurate, neutral sound and detailed imaging. They feature 40mm dynamic drivers with a wide frequency response from 5Hz to 22kHz and an impedance of 50 ohms, making them suitable for use with smartphones and higher-end audio sources alike. The earcups are made from hand-crafted natural wood, contributing to a warm, natural sound signature and aesthetic appeal. The headphones include two detachable Kevlar-reinforced, tangle-resistant fabric cables—one with an inline microphone and single-button control for smartphone compatibility, and one standard cable. The On1s have memory foam ear pads and a flexible metal headband with a fabric overlay for comfort. They provide passive noise isolation and minimal sound leakage, with a soundstage that is fairly wide for on-ear closed-back headphones. The build quality combines wood and plastic components, with some reports of the plastic parts feeling less robust, though the overall durability is supported by the manufacturer. The package includes a cotton carrying pouch and a two-year limited warranty. These headphones are praised for their neutral, monitor-like sound with a slight bass enhancement, clear mids, and detailed highs, suitable for both critical listening and enjoyable music playback.
