Space 2 Pro headphones are the headline act of Anker’s biggest audio announcement of the year. At IFA 2026 in Berlin, the company confirmed that its proprietary Thus AI chip — until now reserved for the flagship Liberty 5 Pro earbuds — is spreading across five audio models, and the wireless Soundcore Space 2 Pro over-ear headphones lead the charge. Priced at $200 and shipping from September 22, they promise adaptive noise cancellation driven by an eight-sensor array, real-time voice separation on calls, and up to 60 hours of battery life.
The pitch is simple: premium, AI-processed sound at a mid-range price. Anker has spent fifteen years climbing from power banks to a proprietary audio processor it calls the world’s first compute-in-memory AI audio chip. The Space 2 Pro is the first over-ear product built around that silicon, and it lands alongside new earbuds, sleep buds, and Anker’s first over-the-counter hearing aids.
This guide covers everything announced: what the Thus chip actually does, the full Space 2 Pro spec sheet, how the headphones compare with the rest of the IFA 2026 lineup, and whether the $200 price makes sense against the competition.

Space 2 Pro Headlines Anker's IFA 2026 Audio Lineup
Anker used IFA 2026 to make a statement: the era of licensing generic Bluetooth audio silicon is over, at least for its premium products. Every major product it announced in Berlin carries the Thus chip, and the Soundcore Space 2 Pro sits at the top of the consumer stack.
The five Thus-powered models announced
The lineup spans the whole listening day. The Liberty Buds 2 cover everyday earbuds duty at $130, the AeroClip 2 and AeroClip 2 Pro serve the open-ear crowd at $170 and $230, the Space 2 Pro handles over-ear listening at $200, and a new RIC hearing aid line takes the same silicon into clinical-grade territory.
| Product | Type | Price | Availability | Standout feature |
|---|---|---|---|---|
| Soundcore Space 2 Pro | Over-ear headphones | $200 | September 22 | 8-sensor adaptive ANC, HearID 5.0 |
| Liberty Buds 2 | In-ear earbuds | $130 | September 22 | 9.2mm wool paper diaphragm |
| AeroClip 2 | Open-ear clip buds | $170 | September 22 | Clip design with Thus audio processing |
| AeroClip 2 Pro | Open-ear clip buds | $230 | TBC | On-device transcription and summaries |
| RIC Hearing Aids | OTC hearing aids | TBC | TBC | Four-mic AI speech clarity |
A brand consolidation to match
The hardware news came with a corporate one: Anker is unifying its sub-brands under the single Anker name, taking a page from Apple’s simplified branding playbook. Soundcore remains the audio product line, but the parent identity is now front and centre — a sign of how strategically the company views its in-house silicon.
Why the over-ear model matters most
Earbuds have carried Anker’s audio reputation so far, but over-ear headphones are where buyers scrutinise sound quality hardest. Putting the Thus chip into the Space 2 Pro is Anker betting that AI processing can close the gap with headphones that cost twice as much, in the category where that gap is most audible.
The Thus Chip: Compute-in-Memory AI Explained
The Thus chip is the reason this launch is more than a routine refresh. Announced in April 2026 and debuted at the Anker Day event in New York that May, it is described as the world’s first neural-net compute-in-memory AI audio chip — silicon built specifically for wearables rather than adapted from general-purpose designs.
What compute-in-memory actually means
Conventional processors shuttle data back and forth between memory and compute units, and that movement — not the maths — consumes most of the power. Anker says traditional chips waste over 90 percent of their energy moving data around. The Thus chip’s compute-in-memory architecture, built on NOR-Flash memory, runs AI calculations inside the memory itself, eliminating that round trip.
The result, according to Anker’s internal lab tests, is up to 150 times more peak AI computing power than its previous flagship earbud chip, while staying inside the milliwatt power budget of a battery-powered wearable. The design also needs roughly one-sixth the physical space of an equivalent SRAM-based approach — critical when the processor has to fit inside an earbud. In practice, each neural network runs where its weights already live, so the chip can hold millions of parameters active without draining the battery that playback depends on.
| Factor | Conventional audio chip | Thus compute-in-memory chip |
|---|---|---|
| Data movement | Constant memory-to-processor transfers | Calculations run inside the memory |
| Energy profile | Over 90% lost to data movement | Movement losses largely eliminated |
| Peak AI compute | Baseline | Up to 150x (internal lab tests) |
| Physical footprint | SRAM-based baseline | Roughly one-sixth the space |
| Cloud dependency | Heavier features offloaded | Runs entirely on-device |
A track record before the headphones
The chip is not unproven. It shipped first in the Liberty 5 Pro earbuds, which earned Guinness World Records certification in April 2026 for the highest speech quality score for true wireless earbuds. The same silicon supports 20 voice commands processed completely on-device, with zero cloud involvement — a privacy point Anker leans on heavily.
From power banks to processors
For a company that built its name on charging accessories, designing custom AI silicon is a remarkable pivot. It mirrors a broader industry pattern we have tracked, from Nvidia’s $3.5B MediaTek bet to Acer’s RTX Spark AI desktop push: hardware makers increasingly see owning the AI processing layer as the way to differentiate.
Space 2 Pro Features: ANC, Calls, and HearID 5.0
The Space 2 Pro puts the Thus chip to work in three main jobs: cancelling noise, cleaning up calls, and personalising sound. Each depends on running neural networks fast enough to react to the world in real time.
Adaptive noise cancellation with eight sensors
The Space 2 Pro uses an eight-sensor array feeding the Thus chip, which adjusts cancellation continuously to the environment rather than toggling between fixed modes. On-chip processing means the system can react to a train announcement or a sudden burst of office chatter without the latency of round-tripping audio to a companion device.
Real-time voice separation on calls
Calls get the same treatment. The Space 2 Pro runs voice separation and noise separation models live during conversations, isolating your speech from background clamour. This is the technology lineage that earned the Liberty 5 Pro its speech-quality world record, now with the larger microphones and battery budget of an over-ear design.
HearID 5.0 personalised sound
HearID 5.0 generates a personalised hearing profile and adapts playback to it, running several AI models simultaneously — hearing analysis, audio detail restoration, and environment adaptation. The Space 2 Pro delivers the result over a Hi-Res capable, LDAC lossless signal path, so the personalisation is not undone by a lossy Bluetooth codec.

Space 2 Pro Battery Life, Price, and Release Date
The Space 2 Pro ships on September 22, 2026 at $200, positioning it squarely against the mid-range establishment while undercutting flagship models from Sony and Bose by $150 or more.
Battery life in both modes
Anker quotes 30 hours of playback with adaptive ANC engaged and 60 hours with it off. Even the ANC-on figure covers a week of commuting or several long-haul flights without a charge; switching cancellation off literally doubles the runway.
Battery life halves with ANC on — 30 of the 60 maximum hours:
Where $200 sits in the Thus lineup
Within Anker’s own range, the Space 2 Pro costs $70 more than the Liberty Buds 2, $30 more than the AeroClip 2, and $30 less than the transcription-focused AeroClip 2 Pro. Scaled against the $230 AeroClip 2 Pro at the top of the announced pricing, the ladder looks like this:
The value question
At $200 the Space 2 Pro is not competing with budget headphones — it is asking whether AI processing plus a lossless codec path can substitute for the premium tuning of much dearer rivals. What Hi-Fi framed the launch exactly that way: can an AI chip deliver premium sound from affordable headphones? Review units will settle it, but the on-paper case is unusually strong.
What reviewers will be testing
Three claims deserve scrutiny when Space 2 Pro review units land. First, whether adaptive ANC genuinely tracks changing environments better than the fixed modes on similarly priced rivals. Second, whether the voice separation on calls holds up in the genuinely hostile settings Anker trained for — busy streets, open offices, airport gates. Third, whether HearID 5.0 personalisation produces an audible improvement over a well-tuned default curve, or simply a different one. The Liberty 5 Pro’s Guinness-certified call quality suggests the underlying models are real; the over-ear execution is what remains unproven.
How the Space 2 Pro Compares With the Rest of the Lineup
Choosing between the new models comes down to where and how you listen. The Space 2 Pro is the pick for immersion and travel; the earbuds trade isolation for portability and all-day wear.
Space 2 Pro vs Liberty Buds 2
The $130 Liberty Buds 2 share the eight-sensor approach and add a 9.2mm wool paper diaphragm driver. They are the value play for everyday listening, but the over-ear design of the Space 2 Pro brings larger drivers, stronger passive isolation, and double-to-quadruple the battery life of any earbud format.
Space 2 Pro vs AeroClip 2 and AeroClip 2 Pro
The AeroClip models clip to the ear and leave it open — built for awareness during runs, commutes, and office days. The $230 AeroClip 2 Pro adds a genuinely new trick: it can capture conversations, transcribe them, and answer questions about what was discussed, applying natural language processing entirely on the wearable. The Space 2 Pro skips transcription but wins decisively on immersion, ANC depth, and battery.
Which model fits which buyer
Commuters and flyers should shortlist the Space 2 Pro; gym-goers and cyclists the AeroClip 2; meeting-heavy professionals the AeroClip 2 Pro; and anyone easing into the ecosystem the Liberty Buds 2. All four share the same on-device AI core, so call quality and voice control behave consistently across the family.
For travellers specifically, the maths favours the over-ear model. A 30-hour ANC-on rating covers a London-to-Sydney routing with hours to spare, the earcups double as passive isolation when the battery does run flat, and the metallic taupe finish is restrained enough for a business cabin. Earbuds win on pocketability, but nobody regrets having the bigger battery at hour nine of a long-haul flight.
Sleep Earbuds and Hearing Aids Round Out the Range
Beyond the headline consumer models, Anker used IFA 2026 to push the Thus platform into two categories where on-device intelligence matters even more: sleep and hearing health.
Sleep Earbuds 4 and 4 Pro
The Sleep Earbuds 4 arrive in October, with the Sleep Earbuds 4 Pro following in November. CNET’s early coverage called the previous generation a favourite red-eye flight companion, and the new models focus on comfort and smarter masking of night-time noise. For light sleepers, tiny buds that process sound locally — with no streaming required — are an easier sell than bulky headphones. They also fill the one gap in the flagship’s brief: nobody sleeps in over-ears, so the sleep line and the Space 2 Pro divide the day between them rather than competing.
Anker’s first OTC hearing aids
The RIC Hearing Aids are the most consequential quiet announcement. Powered by the same chip, they use four microphones to improve speech clarity in noisy social settings, and they charge fast: five minutes delivers two hours of use, and a 12-hour case charge yields 36 hours of total battery. Anker entering the over-the-counter hearing aid market puts serious price pressure on an industry where devices routinely cost thousands.
One platform, many form factors
The strategic thread is unmistakable. Design one efficient AI audio processor, then amortise it across headphones, earbuds, sleep aids, and medical-adjacent devices. The audio range also was not alone in Berlin: Anker showed an AI-powered MindBase home hub and a broad security and charging refresh, all under the newly unified brand — but the Thus silicon is the piece none of its competitors can buy off a shelf. It echoes the platform logic behind Perplexity’s local-model Hybrid mode on the software side: push the intelligence to the device, and the experience gets faster, cheaper, and more private all at once.
Why On-Device AI Audio Matters for Buyers
The Space 2 Pro launch is part of a wider shift in consumer electronics: AI features migrating from the cloud into the products themselves. For audio, that shift has three practical payoffs.
Latency you can hear
Noise cancellation and voice separation only work if they react in milliseconds. A chip that runs neural networks locally can adapt cancellation mid-announcement and clean a call as you speak. No cloud round trip can match that, whatever the model size on the server side.
Privacy by architecture
Voice commands, call audio, and — on the AeroClip 2 Pro — full conversation transcripts are processed on the wearable itself. Nothing needs to leave the device for the core features to work, which materially shrinks the trust question compared with assistant earbuds that stream audio to servers.
Battery economics
Compute-in-memory efficiency is what lets the Space 2 Pro promise 30 hours of AI-driven ANC. Wasting 90 percent of the energy budget on data movement was tolerable when chips did simple filtering; running genuine neural networks all day demands the architectural fix. We track this on-device AI trend — and the models and silicon behind it — in our AI models and tools hub.
The competitive ripple
If a $200 product delivers on these claims, the pressure lands on Sony, Bose, and Apple to justify $350-plus pricing — and on chipmakers, since Anker just demonstrated that a device brand can design category-defining silicon in-house. Either way, buyers win: the AI audio arms race has moved to the mid-range.
Space 2 Pro FAQ
When does the Space 2 Pro go on sale?
The Space 2 Pro goes on sale September 22, 2026, alongside the Liberty Buds 2 and AeroClip 2. The AeroClip 2 Pro, Sleep Earbuds 4 and 4 Pro, and the RIC hearing aids follow later in the autumn.
How much does the Space 2 Pro cost?
$200. That places it $150 or more below flagship ANC headphones from Sony and Bose, and $30 below Anker’s own AeroClip 2 Pro open-ear buds.
What does the Thus AI chip actually do in the Space 2 Pro?
It runs the neural networks behind adaptive noise cancellation from the 8-sensor array, real-time voice separation on calls, and HearID 5.0 sound personalisation — all on the headphones, with no cloud processing.
How long does the battery last?
Anker quotes 30 hours with adaptive ANC on and 60 hours with it off. For comparison, most flagship ANC over-ears quote 24 to 30 hours with cancellation enabled.
What is the Thus chip in plain terms?
It is Anker’s own audio processor that runs AI calculations inside its memory instead of shuttling data to a separate compute unit. That compute-in-memory design avoids the energy conventional chips lose to data movement, which is how the Space 2 Pro can run always-on AI features within a headphone battery budget.
Is the Space 2 Pro a flagship killer?
On paper the Space 2 Pro undercuts flagships heavily while claiming comparable AI-driven features and longer battery life. Whether the tuning matches the engineering is the open question reviewers will answer when units ship in late September.
