T+A Solitaire P Headphone, Wired, Planar‑Magnetostatic Open‑Back (XLR4)

Hear truth, not hype: reference‑grade transparency with real‑world comfort and craftsmanship

The Solitaire P is built for the listener who’s done chasing flavor-of-the-month signatures and just wants the recording—whole, unforced, and beautifully intact. T+A’s in‑house planar‑magnetostatic driver unlocks a vast, effortless stage with micro‑detail that feels lived‑in rather than lit‑up, while its milled‑aluminum architecture and hand‑finished pads make long sessions feel as considered as they sound. This XLR4 variant ships ready for fully balanced playback, so your chain can disappear and the music can stand up on its own.

Why Audiophiles Choose This Product

• • Sound quality: Natural, neutral‑to‑slightly‑warm tuning with outstanding micro‑dynamics, precise bass control, lifelike timbre, and a wide, stable soundstage. Reviewers consistently praise its “balanced and neutral tonal profile” with extension from airy highs to deep bass that arrives only when the music calls for it.
• • Engineering: The TPM 3100 planar‑magnetostatic transducer uses 19 high‑performance neodymium magnets and an ultra‑thin, vapor‑deposited conductor on a lightweight film, with a laminar airflow design that minimizes turbulence and distortion. The result: very low THD (<0.015% @ 100 dB) and high dynamic range.
• • Practicality and build: Earcups and yokes are CNC‑machined from solid aluminum; pads and headband are hand‑made in Germany from allergen‑free synthetic leather and Alcantara for long‑wear comfort. Military‑grade two‑pole connectors at the earcups ensure secure, serviceable cabling.
• • Compatibility: With 80 Ω impedance and 101 dB/1V sensitivity, the Solitaire P is comparatively easy to drive for a flagship planar and scales beautifully with desktop amplification—single‑ended or fully balanced.
• • What sets it apart: Elliptical 110×80 mm driver geometry, a meticulously controlled magnetic field for true laminar airflow, and T+A’s low‑inductance, low‑capacitance cable architecture deliver reference clarity without edge or fatigue—an uncommon combination in the category.
