Satin Aluminum TH1 Closed-Back Audiophile Headphones with Vacuum Tube Preamp Bundle — 3.5mm cable included

The écoute TH1 is the world's only headphone with a built-in vacuum tube preamp stage. Inside its closed-back, over-ear frame is a complete hi-fi signal chain: a dual-core high-resolution DAC, a real vacuum tube preamp, custom tunable 8-band parametric DSP, and true dual-mono amplification architecture with fully independent channels from DAC to driver.

The tube preamp stage shapes harmonic structure and microdynamics before the signal reaches amplification — the same function it performs in a reference rack system. Dual-mono architecture keeps left and right channels physically separate throughout, eliminating inter-channel crosstalk and preserving the imaging and spatial depth of the recording. The result is an exceptionally wide soundstage, natural realistic warmth, and detail you'd expect from a full hi-fi system.

The écoute TH1 was designed for listeners who want reference-grade audio wherever they listen — wired or wireless. Among the best tube headphones and wireless headphones for audiophiles, it delivers the experience of a serious hi-fi system with the convenience of modern wireless headphones. Bluetooth 5.3 with LDAC for high-resolution wireless listening, USB-C lossless digital input, 3.5mm analog, and active noise cancellation. The complete signal chain of a reference hi-fi system — DAC, tube preamp, dual-mono amplification — in a portable headset.
