Music streaming service Tidal is increasing the pricing of its HiFi tier by one dollar from $9.99 to $10.99 a month on August 1st, the company is announcing in emails to subscribers, Billboard reports. Similar price increases appear to be coming for international subscribers as well, according to reports on Reddit, with users in markets like the UK, Germany, Spain, Mexico, and Argentina all saying they’ve been contacted.

In addition to increasing the price of its standard HiFi plan, Billboard reports that Tidal is also increasing prices for its family plan by two dollars from $14.99 to $16.99. It’s currently unclear if a price increase is coming for US subscribers to Tidal’s HiFi Plus tier, the $19.99 subscription that currently offers access to Dolby Atmos music, Sony 360 Reality Audio, MQA tracks, and hi-res FLAC. Fewer subscribers to this more premium tier have reported receiving notices, but at least one HiFi Plus subscriber in Argentina says they’ve received an email.

We’ve reached out to Tidal for more specific information about the price increases globally and will update this piece if and when we hear back.
