Ecoute Audio TH1

The Ecoute Audio TH1 is the world’s only headphone with a built-in vacuum tube headphone amplifier and preamp, delivering the warmth and dimensionality of true analog amplification. Inside its closed-back, over-ear frame is a complete audiophile-grade signal chain: hi-res DAC, a custom-tunable DSP, and dual-mono analog amplification for precise channel separation and clarity. The result is an exceptionally wide soundstage, the natural, realistic warmth you would expect from vacuum tubes, and detail that rivals reference-grade hi-fi systems costing many times more. With Bluetooth 5.3 (LDAC/AAC) for high-resolution wireless listening, USB-C digital for lossless playback, 3.5mm analog input, active noise cancellation (ANC), and app-based tuning, the TH1 combines the performance of high-end wireless audiophile headphones, a headphone DAC, and a portable vacuum tube headphone amplifier in 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.
