Beyerdynamic Say….
The T 90 is an open hi-fi headphone, and therefore the ideal choice for music lovers, who listen to the music in acoustically favourable environments. The open design gives the T 90 a spatial sound and avoids the feeling of being isolated from the environment. Due to the latest Tesla technology the T 90 provides highest efficiency and lowest distortion. Silky-soft head and ear pads made of micro velour’s and microfibre ensure maximum comfort of wearing. The T 90 is also made in Germany as all premium headphones from Beyerdynamic.
