The company launched a trade-up scheme in 2019 which would allow existing users the chance to get 30% off the cost of a new device, but only if they activated "Recycle Mode".
This irreversible process - which wipes personal data but also stops the internet-connected speaker from working - would mean the speaker would be permanently unusable even if they where nothing wrong with it, but now the firm has backtracked.
Sonos has now removed the requirement from the scheme after criticism over encouraging users to disable working devices.
In a statement, the company said: "We also respect the customer's right to decide for themselves when a product has reached the end of its useful life.
"So, while we are fully committed to supporting customers that wish to recycle their old hardware, we removed the Recycle Mode requirement from the program," the company said in a statement.
"Customers still receive a 30% discount on new Sonos products, but they can now choose what to do with their old device - continue to use it, give it to a friend, donate it to charity, responsibly recycle it at their local e-waste facility or send it back to Sonos via a prepaid shipping label."
