The Canadian Ace Ultra Costs C$120 More Before Tax, With a One-Year Warranty and Early Access at Its Core

C$599 is a shelf price, not a delivered one

Both pairs were on the Canadian store, C$599 for the Ultra and C$479 for the older Ace, with no sale price beside either; the Ultra came in four colours and the older Ace in two, Soft White on backorder for both. The C$120 between them is the number to argue about, and it is a shelf number: the terms state 'All prices displayed on the Sonos website are exclusive of Canadian taxes (GST/PST/HST) as marked.' Black is ACEULUS1BLK, white ACEULUS1 — the North American codes, unlike the ACEULWW1 set sold in Britain and Australia.

What arrives at checkout is higher. 'All items shipped to destinations in Canada are subject to Canadian Goods and Services Tax (“GST”) at 5%. In addition, Provincial Sales Tax (“PST”) or Harmonized Sales Tax (“HST”) may apply', the terms continue, with the amount worked out from the shipping destination and a Canadian tax invoice emailed after the order. On a C$599 order that 5% is a federal line the page never shows, and a province can add more. Treat C$599 as the price before tax, because that is how the terms describe it.

One year of cover, printed in the Canadian terms

The Canadian terms offer 'a one (1) year full warranty on all products sold', covering defects in materials and workmanship for twelve months from dispatch by Sonos or from the original retail purchase at an authorized dealer. Repair or replacement is the remedy, the period does not extend when a unit is serviced, and the terms add that local consumer protection laws may give additional rights the warranty does not restrict.

The exclusions matter on this pair. They cover products 'which have had their housings opened or are otherwise tampered with', and Sonos's own C$39 battery kit page says the swap 'requires disassembly and tools'. Nothing read today says whether fitting that kit counts, so ask Sonos Support about service options before opening a cup inside the first year.

What C$120 changes, and the swap the old Ace already had

The spec row on the older model's page spells it out already: 'Press the Content Key to swap sound from a compatible Sonos soundbar to one or two Sonos Ace headphones.' That same page also carries a marketing line about sending TV audio straight to the headphones. TV Audio Swap is therefore not something the C$120 introduces, and late-night television listening does not require the C$599 pair at all.

What the C$120 buys without a linked system is a longer day and a newer radio. The rated day grows by five hours with noise cancelling on, to up to 35 at moderate volume, and three minutes of charging still yields up to three hours. Ten microphones read the room where eight did, and Bluetooth 6.0 replaces 5.4; the 2x ANC claim is footnoted to frequencies up to 65 Hz. A buyer after Bluetooth noise cancelling can leave these alone: the C$479 Ace already cancels noise, plays spatial audio with dynamic head tracking and takes lossless over USB-C.

The system link is opt-in, as-is, and still being built

Headphone linking takes up most of the page's space, and it is still Early Access. Sonos's guide calls it 'an Early Access feature, provided on an as-is, opt-in basis' that 'may change, be limited, or be temporarily unavailable' while work continues. The setup article adds the gate: only the Ace Ultra is supported, and the system needs at least one listed product — speakers such as Era 100, Roam 2 and Move 2 count as well as the Arc, Beam and Ray bars — plus Wi-Fi and the Sonos app. The guide adds that vocal guidance, the spoken battery and Bluetooth announcements, is English only for now.

A few mechanics are attached to that link. A long press of the Content Key pulls audio from the nearest actively playing Sonos product in the room, and the support article says the swap may take up to five seconds; the same press sends it back to a compatible speaker nearby. For television, a session allows no more than two sets of Sonos headphones, dynamic head tracking is disabled while two are connected, and the TV has to be on and already playing through the bar. Linking setup also configures TV Audio Swap with every compatible soundbar in the home — Arc, Arc SL, Arc Ultra, Beam (Gen 1), Beam (Gen 2), Beam Ultra and Ray.

When the C$120 is better left on the older Ace

With nothing from the linking list in your Sonos system, leave the C$120 alone and keep the C$479 Ace. The link does nothing until one of those products is on the system, and the TV feature is already on the cheaper pair's page. Someone who only wants noise cancelling on a flight gets that from the C$479 pair already.

At 0.322 kg it is a full-size over-ear pair, 193 mm tall, not a lighter revision. Sonos sells replacement ear cushions at C$59 a set and the battery kit at C$39, the latter flagged as a disassembly job for people comfortable with tools.

C$599 is the shelf price and C$120 the step, both before the 5% GST and any provincial line the checkout adds. Neither price carries a deadline today; the Ultra was orderable in all four colours and the older Ace in its two, Soft White on backorder for both, with free shipping and 30-day returns. Check the products in your Sonos app against the linking list: one listed product on Wi-Fi is what makes the C$120 worth paying, and without one the older pair is the better C$479.
