T+A SOLITAIRE T

The T+A Solitaire T marks a decisive step in the evolution of the German brand. Designed to "blur the distinctions between audiophile, work, and travel headphones," this closed-back, circumaural model transcends traditional categories, offering unprecedented versatility. Where the previous Solitaire P headphones required a dedicated listening environment, the Solitaire T adapts to any listening environment, maintaining the T+A quality standards.

Premium Construction and German Durability

The Solitaire T's construction philosophy reflects T+A's uncompromising approach. The pearl-finished aluminum components are machined entirely from solid billet aluminum, going beyond mere aesthetics to ensure exceptional strength. This meticulous construction ensures durability designed to last for years.

The ear and headband cushions use high-quality, anti-allergic synthetic leather, optimizing comfort during long listening sessions. Despite their solid construction, the headphones weigh just 326 grams, a testament to the structural optimization achieved by German engineers.

The design establishes a subtle yet distinctive visual link with the Solitaire P reference models, affirming their belonging to this line while also highlighting their functional uniqueness.

Technological Versatility and the Active Analog Concept

The Solitaire T revolutionizes the traditional approach thanks to its connectivity versatility. Three wired inputs are available: 3.5mm, 4.4mm Pentaconn, and 6.35mm connectors, allowing for purely passive use with symmetrical signal transfer. The USB-C port enables fully digital listening without data compression.

The proprietary "Active Analog" concept represents a significant innovation. This approach maximizes the potential of analog inputs, offering access to volume control and active noise cancellation, combining the advantages of pure analog with modern features.

In wireless mode, the Qualcomm QCC 5127 chipset handles 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 drivers were developed specifically for this model. Selected for their tight 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 impeccable transient response while preserving the integrity of the frequency response. This meticulous design allows for authentic performance in both active and purely passive modes.

The hybrid active noise reduction is based on four microphones: two dedicated ANC on each earcup, plus two communication microphones on the right side. This architecture ensures effective cancellation without creating unpleasant pressure on the eardrum. Three listening modes are available: ANC, Ambient, and High Quality, with ANC mode slightly warming the sound signature.

Exceptional battery life and ease of use

The 1200 mAh lithium-ion battery offers a remarkable 70 hours of battery life in standard use, reduced to 35 hours in High Quality mode. This battery life 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 simultaneously listening via USB-C, recommending separating charging and listening.

The user interface combines textured physical buttons and an interactive touchpad. The right earcup features touch controls for volume, playback, and navigation, while the physical buttons manage power, pairing, and mode selection. A double tap activates transparent mode, and a light indicates the Bluetooth codec used.

Accessories and Connection 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 every setup.

The included adapters cover specific needs: an airline adapter for travel and a 6.35mm converter for home hi-fi systems. This comprehensive approach eliminates the need for additional accessories for most applications.

Compatibility extends to a wide variety of sources: smartphones via Bluetooth or USB-C, audiophile players via symmetrical connections, traditional hi-fi systems, and even professional use thanks to the built-in microphones and voice assistant.
