écoute TH2: The World’s Only
Headphones With a Real Vacuum Tube
Wangdoo Scorecard — écoute TH2
Why These Headphones Are Unlike Anything Else
écoute Audio is a San Diego, California-based startup that in 2023 launched the TH1 — the world’s first wireless headphones with a built-in vacuum tube preamp and dual-mono amplification. The TH1 was met with genuine enthusiasm from the audiophile press, reviewed seriously by publications including Positive Feedback and The Absolute Sound, and proved that a true analog signal path could exist inside a portable headset. The TH2 is its evolution — refining every element of the original architecture while expanding its capabilities.
The TH2 debuted publicly at CanJam Dubai before its Kickstarter launch on 11 February 2026. It was also demonstrated at CanJam NYC on 7–8 March 2026, where listeners could directly compare TH1 and TH2. The campaign closed on 12 March 2026 having raised $620,978 from 831 backers — 6,200% of its $10,000 goal. The average pledge was approximately $741, reflecting the device’s premium positioning. General retail availability is expected in September 2026, with worldwide shipping.
“What if your headphones didn’t sound like headphones?” — écoute Audio’s founding design question
What makes the TH2 genuinely different
- The only wireless headphones in the world with a real vacuum tube preamp built into the earcup — not a DSP emulation
- True dual-mono architecture: physically separate left and right signal paths from DAC to driver — eliminating crosstalk at a structural level
- 32-bit/384kHz dual-core DAC — far beyond the 24-bit/96kHz of most hi-res streams
- 40mm titanium-coated mylar drivers — one per channel, driven independently
- The TH1 was funded, shipped, and praised — écoute has an established delivery track record
Inside the Signal Path — How It Actually Works
Understanding why the TH2 sounds different requires understanding how it’s built. In a typical wireless headphone, both channels share a single amplification circuit — efficient and compact, but at the cost of channel separation and stereo imaging. écoute takes the opposite approach, modelling the internal architecture of a two-channel home hi-fi system.
The Korg Nutube 6P1 is a modern, miniaturised vacuum tube designed specifically for portable use — it runs at low voltage, generates minimal heat, and is far more resistant to shock than traditional glass tubes. It is the same component used in Korg’s own Nutone guitar amplifiers. In the TH2, it performs genuine voltage gain: shaping the harmonic structure and microdynamics of the signal before it reaches the solid-state amplification stage. This is why tube-based audio has a reputation for warmth and spatial depth — it is not a tone control, it is a fundamental change to how the signal is processed.
Why dual-mono matters for headphones
- In conventional headphones, both channels share amplification — left and right bleed into each other, collapsing the soundstage
- TH2 physically separates left and right throughout the entire chain — DAC → tube → amplifier → driver
- This preserves the stereo imaging embedded in the original recording with precision normally only found in rack-mounted hi-fi systems
- Additional RF shielding around the tube stage reduces interference from Bluetooth and external sources — a known challenge in tube-based portable design

Three Ways to Listen — No Compromises
Unlike many audiophile headphones that force a choice between wireless convenience and wired fidelity, the TH2 offers three fully independent input paths — each feeding into the same dual-mono tube architecture.
What’s Actually New Over the Original TH1
The TH2 is not a rebrand. It builds on the TH1’s proven architecture with measurable improvements across sound, ergonomics, noise control, and shielding — while preserving the core dual-mono tube signal path that made the TH1 stand out.
Confirmed upgrades over TH1
- Deeper bass extension and more extended treble — improved resolution across the full frequency range
- Lower ANC noise floor — cleaner noise cancellation with less artefact
- More natural transparency mode — better ambient sound integration
- Better passive isolation — reduced bleed in and out of the earcups
- Additional RF shielding around the tube stage — reduced microphonics and interference
- Redesigned chassis and new hybrid suspension headband — improved weight distribution and comfort over long sessions
- Modular design — replaceable pads, headband wrap, and head pad for longevity
- New Charcoal colour option added after $500K stretch goal was unlocked
écoute TH2 vs Sony WH-1000XM6 vs AirPods Max
The TH2 competes on price with Sony’s flagship noise-cancelling headphones and Apple’s AirPods Max — but it is a fundamentally different product. These are not lifestyle headphones. They are audiophile instruments.
