The owners of Sonos products have reacted angrily to the announcement of the company that from May it will no longer release software updates for its older devices.
Many claim to have spent hundreds of pounds on Sonos speaker products for their homes over the years.
Newer Sonos products linked to previous ones will be excluded from future updates.
The change affects four models sold between 2006 and 2015, including Connect: Amp and Connect.
Without the updates, they will eventually lose functionality.
Access to other services will also be limited.
Sonos said the hardware has been “extended to its technical limits in terms of memory and processing power”.
And interested customers can switch to a newer device with a 30% discount in exchange for recycling the old product.
But the news annoyed many Sonos owners.
And Sonos told BBC News that 92% of the products he had ever shipped were still in use.
BBC technology correspondent Rory Cellan-Jones tweeted that it was “very poor and harmful to the brand marketing”.
The Sonos share price fell slightly after the announcement, closing at $ 14.80 (£ 11), down from a high of $ 15.05.
