Écoute TH2: Next-Gen Tube Headphones with Improved Sound & Comfort

San Francisco-based audio brand Écoute is building on its innovative foray into vacuum tube-powered headphones with the launch of the TH2. The TH2, currently available via a Kickstarter campaign launched on February 11, 2026, represents a refinement of the company’s original TH1 headphones, introduced in 2023, which were the first over-ear headphones to integrate a built-in vacuum tube preamp and dual-mono amplification.

Écoute’s core design philosophy centers around the question: “What if your headphones didn’t sound like headphones?” The company believes the answer lies in replicating the experience of a high-fidelity (HiFi) system within a portable form factor. At the heart of both the TH1 and TH2 is the use of triode tubes in the signal path, responsible for voltage gain – a critical stage in any HiFi system. According to Écoute, this gain stage determines whether subtle nuances in audio, such as microdynamics, harmonic structure and spatial information, are preserved.

The TH2 isn’t a complete redesign, but rather a focused effort to improve upon the foundation laid by the TH1. While retaining the core architecture of its predecessor – the vacuum tube preamp and dual-mono amplification – the TH2 boasts several key upgrades. These include improved sound quality, with deeper bass, extended treble, and increased resolution across the frequency spectrum. The company has also redesigned the chassis and headband to enhance comfort through better weight distribution and improved durability.

A key feature of the TH2 is its modular design, allowing users to easily replace pads and headband wraps, extending the lifespan and customizability of the headphones. Écoute has also focused on improving noise control, achieving a lower noise floor in the active noise cancellation (ANC) mode and a more natural sound in transparency mode, alongside better passive sound isolation.

Beyond hardware improvements, the TH2 offers greater control over the audio experience. Users can customize the sound profile with eight adjustable frequency bands, each offering a ±12 dB adjustment. This level of customization allows for a tailored listening experience to suit individual preferences and music genres.

The rapid development cycle from the TH1 to the TH2 – less than four months – suggests that the TH1 was intended as a proving ground for the concept, according to Écoute. The company appears to be moving quickly to refine and expand on its initial design while maintaining momentum. Initial reactions to the TH1 were generally positive, with eCoustics Founder and CEO Brian Mitchell noting his generally impressed experience at CanJam SoCal 2025. However, a demo unit at CanJam also received criticism, with one Redditor noting that it “did not sound good at all” despite having good build quality (r/headphones).

The TH2’s development also appears to be progressing quickly, with pre-production units already being sent to reviewers as of January 28, 2026. A recent sound challenge video comparing the TH2 to the TH1 was published on February 3, 2026 (YouTube).

Écoute emphasizes that the TH2 represents a refinement of the original concept, aiming for a more musical and lifelike listening experience. The company’s goal is to allow listeners to enjoy the sound they love without compromising on portability or fidelity. The TH2 builds on the TH1’s success in demonstrating that a true analog signal path can be successfully integrated into a portable headphone design.
