The soprano enchants with her timbre, sensitive musicality and sinuous legato which are irresistible.
NDR Kultur 

In songs by Sibelius, Grieg or Frank Bridge, Wegener explores the depths of the soul and lets her marvellously radiant voice, as powerful as it is rich in colour, and calm, perfectly balanced vibrato glide over the water conjured up by pianist Götz Payer, which at times delicately sparkles, at others swells powerfully like waves.
FAZ, 2017

Wegener’s ability cannot be disputed. The placement of her voice is flawless, she has the complete range of ambitious tone colour, superb timbre that still remains smooth even at a high volume, and perfect legato.

Sarah Wegener is excellent in the role of Signe, ending on a celestial high.
Evening Standard, Barry Millington, November 2015

[...]and midwife Sarah Wegener, who is competent in this initial role before returning as Johannes’s daughter Signe. As Signe, she is the most authentic and moving character we encounter; discordant, mournful und distant and first, and finally gasping out her grief in a hoarse, poignant whistle.
Londonist, Holli-Mae Johnson, November 2015

Sarah Wegener is an extraordinary soprano, with a round and supple voice.
Musicologie.org, Eusebius, February 2015 (on the performance of Dvořák's Stabat Mater with the Orchestre des Champs-Élysées under Philippe Herreweghe at the Opéra de Dijon)

The beauty, the expression that never seems to be put on, with which Wegener interprets this farewell music so securely in the high registers is simply fantastic.
Kronen Zeitung, Martin Gasser, November 2014 (on Richard Strauss’ Four Last Songs)

What the soprano Sarah Wegener mastered with her concise interventions of vocal stunts – and how she made these warm and cantabile, never sounding shrill in the higher ranges – borders on the miraculous.
Frankfurter Rundschau, Holger Noltze, January 2014 (on the world premiere of Widmann's III Labyrinth)

The soprano Sarah Wegener was sensational when she joined in the third and fourth movements of Schönberg’s second string quartet in F-sharp minor op. 10. She made her voice sound almost instrumental, infinitely refined with a wide range of dynamics, a large spectrum of colours and gorgeously dramatic expressivity.
Zürcher Kultur, Alfred Zimmerlin, January 2014

We must explicitly mention Sarah Wegener. The soprano addressed herself to the second work by Haas “…wie stille brannte das Licht” with an extraordinarily brilliant intonation. Haas quite often linked the soprano part very closely to the trumpet part and in the end united both voices in harmony again. Wegener hit all the audacious vocal jumps without losing any of the tonal quality. The precision of her voice is fantastic and was the reason for a well-deserved extra applause.
