TH1 -Closed-Back Audiophile Headphones with Vacuum Tube Preamp

The TH1 is not just another pair of audiophile headphones. It is the world’s only headphone with a built-in vacuum tube headphone amplifier and preamp, delivering the warmth, depth, and dimensionality of true analog amplification.

Inside its closed-back, over-ear design is a complete audiophile-grade signal chain: a high-resolution DAC, a custom-tunable DSP, and dual-mono analog amplification for exceptional channel separation and clarity.

The result is a remarkably wide soundstage, the natural warmth expected from vacuum tubes, and detail that rivals reference-class hi-fi systems costing many times more.

With Bluetooth 5.3 (LDAC/AAC) for high-resolution wireless listening, USB-C digital input for lossless playback, 3.5 mm analog input, active noise cancellation (ANC), and app-based tuning, the TH1 unifies the capabilities of high-end wireless audiophile headphones, a headphone DAC, and a portable vacuum tube amplifier into one design.

These closed-back audiophile wireless headphones deliver the experience of a reference-grade hi-fi system with the convenience, features, and portability of modern LDAC Bluetooth headphones—making them one of the standout headphones of 2025.
