Nobody expected this. Vacuum tubes belong in amplifiers, not in wireless headphones, sitting on a shelf. French company Écoute Audio just changed that with the TH1, and the audiophile world is paying attention.
What Is the Écoute Audio TH1?
Écoute Audio whose name translates from French as “Listen to Sound,” has unveiled the TH1, a pair of Bluetooth headphones built around fully discrete circuitry, including a real vacuum tube preamp stage.

Unlike every other wireless headphone on the market, which uses a standard system-on-chip design, the TH1 uses a Nutube 6P1 dual triode preamplifier developed by Korg and Noritake Itron of Japan. After the tube preamp stage, solid-state Class AB analog amplifiers handle the final drive, a hybrid approach borrowed directly from high-end desktop amplifier design.
The most striking detail is that you can see the tube glowing through a window cut into the left earcup.

Why the Nutube 6P1 Makes This Different
The Nutube 6P1 is not a traditional glass tube it was developed by Korg specifically for portable, battery-powered applications. It runs at low voltage, produces minimal heat, and consumes very little power. But it behaves like a real triode, producing the characteristic harmonic qualities that give tube amplification its warmth and three-dimensional character.

This is why the TH1 can claim 20 hours of battery life; despite the tube circuitry, a conventional tube in the same position would drain a battery in under an hour.
