(Pocket-lint) - Sonos is known for its excellent multiroom speakers but it's been rumoured for some time now that the company will expand into other areas of audio, with wireless headphones looking like it could be top of the list.

We first heard back in early 2019 that Sonos was considering stepping into the headphone market. Since the first murmerings, a few things have happened that have added some fuel to a fire that shows no signs of burning out.

Here's everything we know so far about the potential Sonos wireless headphones.

What will Sonos wireless headphones be called?

So far, there has been no speculation as to what Sonos might call its headphones should it enter this category. We'd expect a simple name, nothing too complicated and nothing with too many numbers or letters, which would be a nice change from traditional headphone naming in the current market.

Given most of Sonos products are simply called one word, such as Sonos One, Sonos Move, Sonos Arc, we'd expect the headphones to carry a similar structure. 

Sonos Headphones, Sonos Head, Sonos Listen, Sonos Aura, Sonos Personal, Sonos Muse, Sonos Go, Sonos Ear, Sonos Free? That's the best the Pocket-lint team could come up with so far.

Release date and price

  • Sometime in 2021?
  • Possibly around $300/£229

Sonos typically does a couple of product launches a year but unlike Apple and Samsung, there isn't a specific week every year where the launches take place.

Given the increase in rumours at the end of 2020, which have continued through 2021, it wouldn't be too surprising to see Sonos announce headphones before the end of the year or early 2022. In 2019, Bloomberg said to expect them before the end of 2020, but 2020 was a strange year so perhaps they were delayed. At the moment, nothing is confirmed.

Sonos took a controlling stake in British headphone manufacturer RHA Audio in October 2021, further adding to the speculation Sonos headphones are coming.

In terms of price, Bloomberg reported the Sonos headphones would cost somewhere in the region of $300 in the US, or £229 in the UK. 

Design

  • Wireless, over-ear
  • Two potential designs
  • Touch controls
  • USB Type-C, line-in

A very detailed patent from September 2020 gives us some idea as to what the design of Sonos headphones could look like, though there are two designs shown and as with all patents, there's no guarantee either design will be final or appear at all.

If the September 2020 patent is anything to go by though, the Sonos headphones will be over ear - though there have been rumours of in-ear too. In one design from the September 2020 patent, the headphones are relatively traditional, with a cup either side and a wide band across the top. 

The second design is a little different however, with stems on the outside of the cups and talk of microphones at the tips. The patent also says wireless and there's talk of ANC control with the potential for a rotating knob, suggesting Active Noise Cancellation could be adjustable.

Additionally, the patent mentions touch control on the outside of the earcups, offering different functions based on the activity, such as a call or music playback. There's also talk of gestures, such as swiping up to increase volume, down to decrease volume, and left or right to skip tracks.

Other controls discussed in the patent include a power button for turning the headphones on or off, or indicating battery status with a long press. A pairing button is also mentioned and a status LED indicator light which would be blue when connected to Bluetooth - like the Move - and white when connected to Wi-Fi.

The charging port mentioned in the patent is USB Type-C and there is also talk of a line-in port.

A different patent also surfaced in February 2021. This too shows an over-ear design with a rounder finish than the design shown in the September 2020 patent, as well as the Sonos logo. The Febraury 2021 patent also shows a USB Type-C port, possibly a 3.5mm jack and there seem to be some buttons around the rim of the earcups, too, likely for touch control. The headphones also might have removable earpads.

In terms of the in-ear patent, there were several images that show two design styles of earbuds and three charging case methods, inlcuding what appears to be USB Type-C, along with detachable battery plates. One of the earbud designs seems a little more normal, while the other appears to be a bit odd on first glance.

Features

  • Work with Sonos system
  • Wi-Fi and Bluetooth 
  • Google and Alexa voice assistants
  • "Swap" feature
  • ANC

Sonos CEO Patrick Spence told Pocket-lint in an interview in September 2019 that if it were to enter a different category, it would have to be connected to the Sonos system and offer something unique. "We're not just going to slap a battery on or slap our brand on something. We want it to be connected to the system and to bring something unique to that space".

We therefore know that if Sonos makes headphones they will work with the Sonos system, as you would expect.

The September 2020 patent mentions Bluetooth and Wi-Fi however, so it's likely you'll be able to send content directly from your smartphone to the headphones over Bluetooth too, like you can with Sonos Move and Sonos Roam, bypassing the Sonos app if you want to. With Sonos Roam the transition happens automatically, which will likely be the case for any headphones too.

The patent also describes the ability to "swap" content playback between the headphones and other devices on a local network by tapping and holding a button - this is essentially the Sonos Swap feature, which launched on the Sonos Roam Bluetooth speaker. You can read more about Sonos Swap in our separate feature, but in theory, we assume you would be able to listen to content on the headphones, pressing and holding a button and transferring it to the nearest Sonos speaker, as you do on Roam.

There's also talk of voice assistants in the patent. As Sonos offers a choice of both Amazon Alexa and Google Assistant on its smart speakers, we would expect both on the headphones too - there's been talk of a Sonos voice assistant in rumours too though. As mentioned in the design section above, there's also talk of adaptable ANC and gesture touch controls. Whether all or none of these features appear though is currently unclear.

Specs

  • Left and right speaker driver
  • Microphone

The Sonos headphone September 2020 patent reads: "In one embodiment, a wireless headphone includes a left earcup comprising a left speaker driver and a left earcup housing; and a right earcup comprising a right speaker driver and a right earcup housing; a processor; a microphone; user controls including: a voice assistant activator control; a volume slider; a play control slider; a play-pause control; and instructions configuring the processor to: commence a voice assistant recognition routine when sound received by the microphone matches a wake word, and perform an action based on instructions returned from the voice assistant; update a current volume of the headphone to a higher volume when the volume slider receives a swipe; skip to a next track of a current media content when the play control slider receives a swipe; and toggle playback of the media content when the play-pause control is activated."

Of course, as the patent is just that, a patent, it might be that any headphones that Sonos launch are nothing like what has been mentioned in terms of specifications, features or design so bear that in mind.
