24-Bit Hi-Res streaming is admittedly more demanding in bandwidth than other qualities.

Domestic usage: a broadband connection is sufficient to enjoy 24-Bit Hi-Res streaming (Wi-Fi or wired connection)

We would recommend a connection speed higher than 10 Mbps. You can test your internet speed on the site www.fast.com.

Mobile data: for optimal experience, it is best to use a 4G connection. If you don’t have a 4G subscription or a compatible smartphone, you can import your albums in advance, from your home Wi-Fi network and listen to your music in “Local” mode.
