Écoute TH1 Headphones

Headphones with valves: meet the Écoute TH1…

More like a wearable hi-fi system than typical Bluetooth headphones, the Écoute TH1 incorporate a high-performance DAC, valve-based preamp and dual-mono amplification

Buckinghamshire, England -- The TH1 by Écoute Audio is a pair of high-end Bluetooth headphones unlike any other. Leading ‘head-fi’ distributor Electromod is delighted to officially bring them to discerning ears in the UK, with immediate effect.

What makes the Écoute TH1 so different? An obvious factor is the incorporation of a vacuum tube – or valve, as we say in the UK – as a preamp stage within the headphones themselves. (The valve is a genuine triode, albeit not a conventional one.) This alone makes them unique, but it’s only part of the story…

Most Bluetooth headphones use SoC (System on a Chip) technology, supplied by IC specialists such as Qualcomm. These chips incorporate all necessary functions to deliver an audio signal to the headphones’ drivers, from Bluetooth reception and processing to D-to-A conversion and amplification. This is an efficient way of doing things; but in terms of sound quality, it is restrictive and lacks refinement.

The Écoute TH1 headphones are designed differently, with a technical architecture distinct from even the most premium Bluetooth headphones. In fact, their design is more akin to a high-end hi-fi system with discrete electronic elements, each engineered to maximise sonic performance and deliver a true dual-mono signal path. Highlights include:

▪ High-resolution dual-core DAC captures every detail.

▪ True valve preamp breathes life into the midrange.

▪ Dual-mono Class A/B amplification maintains channel separation and dimensionality.

▪ Firmware-level DSP tuning lets you shape voicing precisely to your taste via an iOS/Android app.

Remarkably, Écoute has engineered all these elements into the headphones’ durable aluminium body whilst maintaining a comfortable weight of 424g.

When developing the TH1, Écoute asked itself this question: “How do we make the sound of a high-end audio system portable – without compromise?” The result is the closest thing to a hi-fi system you wear on your head.

A hi-fi system on your head

At the headphones’ heart nestles a Nutube 6P1 dual-triode valve acting as a stereo preamp, shaping the signal with harmonic richness and dimensionality before it reaches a pair of discrete Class A/B analogue amplifiers. Developed in Japan by Korg and Noritake Itron, the Nutube 6P1 is tiny in size, runs cool and consumes a fraction of the power of conventional audio valves. Its existence makes the Écoute TH1 concept possible.

The valve is visible through a small display window in the left ear cup, emitting a turquoise glow when the headphones are powered up – a striking visual reminder of its presence. With an expected service life of over 30,000 hours, the Nutube 6P1 is built for many years of use.

The inclusion of the Nutube valve is not a mere effect layered on after the fact – it’s a fundamental part of the discrete signal path within the headphones themselves. With its dual-triode construction, the Nutube 6P1 adds voltage gain whilst keeping the left and right channels separate, handing over to the two mono solid-state amps which maintain channel isolation through to the 40mm titanium-coated Mylar drivers.

This discrete, dual-mono DAC/amp design – unique in a pair of headphones – eliminates crosstalk and preserves imaging with remarkable space, depth and warmth. Instruments lock into place, vocals sound human, details unfold naturally across a three-dimensional soundstage – a listening experience that feels grounded, expressive and unconfined, more like hi-fi separates than Bluetooth headphones.

Listen how you like

As well as Bluetooth for wireless convenience, the TH1 headphones include a USB-C input for cabled digital connections, and a 3.5mm input for analogue sources and external headphone amps. This means you can choose to listen in the following ways:

▪ Bluetooth: High-definition wireless sound with LDAC and AAC support; Bluetooth 5.3 delivers reliable low-latency performance up to 10m from the source device (smartphone, tablet etc).

▪ USB-C input: Hi-res lossless digital sound, up to 32-bit/384kHz.

▪ Analogue 3.5mm input: Select ‘active mode’ to utilise the headphones’ built-in valve preamp and dual-mono power amp. Or ‘passive mode’ to enable an external amp to power the drivers directly, like a regular pair of corded headphones.

Summary of other features

▪ Construction: Closed-back design; aluminium body and armature; adjustable headband;

replaceable fabric-covered over-ear memory foam earpads; physical controls on right ear cup.

▪ Microphone: Built-in mic for calls and voice assistant compatibility.

▪ Noise control: Choice of passive isolation or Active Noise Cancellation (FF and FB) with Transparency Mode setting – the latter uses the built-in mic to pass through some ambient noise, so the listener stays connected to their environment.

▪ Battery: 1600mAh capacity provides 20-plus hours of playback.

▪ Finish options: Gunmetal or Satin Aluminium.

A true world-first, the Écoute TH1 Bluetooth ‘Tube Headphones’ are now officially available in the UK, at an RRP of £900. Customers who purchase the TH1 from an official UK stockist benefit from UK-based tech support and a two-year warranty through distributor Electromod.
