These open, circumaural headphones, the Hi-X65 from Austrian Audio, impressed us with crystal-clear, detailed sound. Their wide frequency range extends from clearly defined sub-basses to impressively detailed mids and fine, brilliant highs. At the same time, these headphones are comfortable to wear and offer a truly functional combination of features and handling. If you want to use top-sounding headphones with a short cable for real hi-fi enjoyment when you’re on the move and perhaps even transport them folded up, the Hi-X65 are the perfect choice. Likewise, these headphones can be used anywhere in the studio where detailed, unpretentious sound is needed in the assessment of audio signals and the open sound-permeable construction is not a problem. With their high sound quality, the Hi-X65 seamlessly join the ranks of Austrian Audio’s impressive headphones and, with an RRP of around 350 Euros, they also score points with a good price-performance ratio compared to the competition.
