What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

T+A
Solitaire T
1700
/
Released
2022
From the first day the Solitaire T was developed with a single goal in mind: to blur the distinctions between audiophile, working and travel headphones by making the values and convictions which are the hallmark of every T+A product accessible in almost every situation in life. Their transducer system is a completely new development, capable of reproducing the most subtle nuances in audiophile quality in active and passive mode alike, while the passive insulation on its own is sufficient to push the outside world into the background.
Check Amazon
T+A is a hifi brand that combines transistor and valve technologies in their HV-Series amplifiers, using high voltage for linear performance, while their A 200 Power Amplifier uses PURIFI Eigentakt technology for low distortion regardless of speaker load.
Expand Details

Our Summary

Product Strengths

  • Impressive sound quality bridges the gap between wired and wireless performance
  • It is a versatile product that can be used as a passive headphone, a USB DAC, or a Bluetooth headphone
  • High build quality, with premium materials like milled aluminum contributing to a robust and luxurious feel
  • Comfortable to wear for extended periods
  • Long battery life, especially in standard mode—up to 70 hours

Product Considerations

  • The fit may not be ideal for those with wider heads
  • The treble response could be sweeter
  • The active noise cancellation may not be class-leading compared to some competitors
  • The volume in wireless mode may not be loud enough for some listeners
  • Soundstage presentation feels intimate compared to full-sized reference headphones

Comparisons (according to reviewers)

  • Vs Mark Levinson No.5909: The Solitaire T has more detail and better organization, though the No. 5909 has a bigger, more spacious presentation
  • Vs Bowers & Wilkins PX8: The noise cancelling of the PX8 is better
  • Vs Focal Celestee: The Solitaire T is comparable when used as a passive wired headphone

Takeaway: The T+A Solitaire T is a versatile and well-built headphone that offers high-quality sound in both wired and wireless modes, making it a great choice for audiophiles on the go or those who want one set of headphones for all situations. Listeners can enjoy music in a lot of different ways with these, and they sound very good.

Comparisons (according to reviewers)

  • Vs Bang & Olufsen H95: H100 has a massive soundstage and is more comfortable
