The T+A Solitaire T marks a decisive milestone in the evolution of the German brand. Designed to “blur the lines between audiophile, professional, and travel headphones,” this closed-back circumaural model transcends traditional categories by offering unprecedented versatility. Whereas previous Solitaire P models required a dedicated environment, the Solitaire T adapts to any listening context while upholding T+A’s demanding quality standards.
Premium Construction and German Durability
The Solitaire T’s construction philosophy reflects T+A’s uncompromising approach. The bead-blasted aluminum components are fully machined from solid material, going beyond mere aesthetics to ensure exceptional robustness. This meticulous build guarantees durability designed to accompany the user for years.
The ear and head pads use high-quality, hypoallergenic synthetic leather, optimizing comfort during extended listening sessions. Despite its solid construction, the headphones maintain a weight of 326 grams, demonstrating the structural optimization achieved by German engineers.
The design establishes a subtle yet distinctive visual link with the reference Solitaire P models, affirming its place in the lineage while asserting its unique functionality.
Technological Versatility and Active Analog Concept
The Solitaire T revolutionizes the traditional approach with its versatile connectivity. Three wired inputs coexist: 3.5mm, 4.4mm Pentaconn, and 6.35mm connectors, allowing for purely passive use with balanced signal transfer. The USB-C port enables fully digital listening with no data compression.
The proprietary “Active Analog” concept is a major innovation. This approach maximizes the potential of analog inputs by granting them access to volume control and active noise cancellation, combining the benefits of pure analog with modern features.
In wireless mode, the Qualcomm QCC 5127 chipset manages Bluetooth 5.1 connectivity with support for SBC, AAC, aptX, and aptX HD codecs. The integrated Quad SABRE HiFi DAC ensures digital-to-analog conversion in active mode, maintaining audiophile quality even without an external source.
Audio Performance and Noise Reduction System
The 42-millimeter transducers have been specially developed. Selected for their low tolerances, they benefit from strategically placed damping to eliminate unwanted reflections. The cellulose diaphragms combine lightness, rigidity, and dynamic agility.
The bass system has been optimized to ensure flawless transient response while preserving frequency response integrity. This meticulous design allows for authentic reproduction in both active and pure passive modes.
The hybrid active noise reduction system relies on four microphones: two dedicated to ANC on each earcup, plus two communication microphones on the right side. This architecture ensures effective suppression without creating unpleasant pressure on the eardrum. Three listening modes are available: ANC, Ambient, and High Quality, with the ANC mode slightly warming the sound signature.
Exceptional Battery Life and User Convenience
The 1200 mAh lithium-ion battery delivers a remarkable 70 hours of standard use, reduced to 35 hours in high-quality mode. This endurance places the Solitaire T among the market leaders, allowing for weeks of use without recharging.
A full charge takes 2 hours via USB-C, with a maximum power of 5 watts. However, some users report insufficient volume when listening via USB-C while charging, recommending separating charging and listening.
The user interface combines machined physical buttons and an interactive touchpad. The right earcup integrates touch controls for volume, playback, and navigation, while the physical buttons manage power, pairing, and mode selection. A double tap activates transparency mode, and a light indicator shows the Bluetooth codec in use.
Accessories and Connectivity Ecosystem
T+A provides a complete set of low-structure-noise OFC cables with gold-plated contacts. This attention to detail ensures optimal transmission in all configurations.
The included adapters cover specific needs: an airplane adapter for travel and a 6.35mm converter for home hi-fi setups. This comprehensive approach eliminates the need for additional accessory purchases for most uses.
Compatibility extends to a wide range of sources: smartphones via Bluetooth or USB-C, audiophile players via balanced connections, traditional hi-fi systems, and even professional use thanks to the integrated microphones and voice assistant.

Frequently Asked Questions
What is the main difference between active and passive modes?
+
In passive mode, the Solitaire T functions as a traditional headphone without built-in amplification, preserving the purity of the analog signal. Active mode engages the integrated DAC and amplification, enabling features like ANC and digital volume control. The Active Analog concept combines both approaches on analog inputs.
How can I optimize the use of the different available connections?
+
Use balanced connections (4.4mm Pentaconn) for compatible audiophile sources, 3.5mm for most portable devices, USB-C for direct digital sources, and Bluetooth for maximum mobility. Each connection is optimized for its specific use.
Can the Solitaire T replace the Solitaire P models for home listening?
+
The Solitaire T offers a different approach with its closed-back design and integrated amplification. While it maintains T+A quality, the open-back Solitaire P models provide a different sense of spatialization for listening in quiet environments. The choice depends on your priorities: versatility (Solitaire T) or pure audiophile specialization (Solitaire P).
User reviews
Nathan
Yes, it is expensive and it is an investment, yes it can be seen as a luxury item. But the second I put it on my ears I understood why. The headphones are very light, you don’t feel them on your head, the ear pads are extremely soft and comfortable, although a little small, so those with large ears should take note. These are demanding headphones, focused on precision and perfect neutrality, requiring you to adjust the EQ to remove a bit of that neutrality, which may not appeal to some people depending on the style of music. The Bluetooth is high quality, but the maximum codec is only APTX HD; the headphones are much more interesting when wired, not only in passive mode connected to a good interface via jack, but also through USB-C via their internal DAC. There is a huge amount of work on the separation of frequencies and harmonics; for listening to unprocessed instrumental music or vocals, it is simply perfect.

Oui, il est cher et c'est un investissement, oui il peut être vu comme un objet de luxe.
Mais à la seconde où je l'ai mis sur mes oreilles j'ai compris pourquoi.
Le casque est très léger, on ne le sens pas sur la tête, les coussinets sont extrêmement moelleux et confortables, bien qu'un peu petits, donc attention à ceux qui ont de grandes oreilles.
C'est un casque exigeant, tourné vers la précision et une neutralité parfaite, nécessitant de bouger l'égalisation pour enlever un peu de cette neutralité qui peut déplaire à certaines personnes selon de style de musique.
Le Bluetooth est qualitatif, mais le codec maximal n'est que l'APTX HD, le casque se montre beaucoup plus intéressant en filaire, non seulement en mode passif branché à une bonne interface en jack, mais aussi en USB-C via son DAC interne.
Il y a un énorme travaille sur la séparation des fréquences et des harmoniques, pour écouter de la musique instrumentale non modulée ou du chant c'est tout simplement parfait.
