Edifier is marking its 30th anniversary at IFA 2026 with a strong audio range spanning studio, home and personal listening.

Founded in Beijing in 1996, Edifier has evolved from a single wooden multimedia speaker into a global audio brand, with products sold across more than 80 countries and regions. Today, its portfolio spans personal, portable, home, Hi-Fi, studio, premium, and gaming audio

Rather than centre its Berlin stand on one flagship product, the Beijing-founded audio brand has built its anniversary showcase around their new,range of devices that each target a different listening scenario.

At IFA, the stand splits into five distinct areas covering personal audio, home entertainment, professional studio monitoring, premium Hi-Fi and gaming, and that split mirrors how Edifier organises its wider product catalogue. Visitors move between those zones to see the new products alongside Edifier’s existing S3000 MKII and AIRPULSE ranges.

Studio monitoring and home audio

The XR6 professional studio monitor pairs an onboard DSP with dedicated PC software to calibrate room acoustics, while a full aluminium enclosure and three-way acoustic design minimise resonance and cabinet coloration. Edifier tunes the monitor for a flat on-axis and off-axis frequency response and targets professional studios and home creators who need accurate playback.

That same emphasis on tuned acoustics carries into the M90 bi-amped speaker system, which delivers 100W RMS output with both Hi-Res Audio and Hi-Res Audio Wireless certification and connects via HDMI eARC, Bluetooth 6.0 with LDAC, USB-C and optical inputs.

The matching MW6T subwoofer adds 210W RMS output, dual 6.5-inch woofers and room acoustic compensation that adjusts bass to suit the room it sits in. Together, the pair forms a two-piece home audio system built for music, film and gaming.

Personal audio and availability

Moving from home to personal audio, the WH950NB Pro over-ear headphones pair adaptive hybrid active noise cancellation across eight microphones with dual dynamic drivers and spatial audio that tracks head movement. A six-microphone AI call system and Bluetooth 6.1 support up to 70 hours of battery life with noise cancellation switched off.

Edifier’s STAX SPIRIT headphones sit at the premium end of that same personal audio range and rely on planar magnetic driver technology more commonly found in dedicated audiophile equipment than mainstream wireless headphones. Edifier pairs that technology with wireless convenience and premium craftsmanship, aimed at creators and listeners who want reference-quality sound.

None of the new products have confirmed UK pricing or release dates so far, with Edifier expected to detail availability for each model in the months following its IFA 2026 stand in Berlin.

The anniversary showcase also includes the flagship S3000 MKII and AIRPULSE Hi-Fi lineup within a dedicated Premium Hi-Fi area. That sits alongside a HECATE gaming zone, and together they round out a stand built around three decades in audio rather than one new release.

After reporting last week that the surveillance company Flock Safety is building an AI search tool for law enforcement, WIRED reconstructed Flock’s latest search tool from code that the company sends to a police officer’s browser and uncovered key details about how the tool works.

OpenAI said this week that its Astra model, which will have a private release soon, is its first model with cybersecurity-related capabilities that the company defines as posing a “critical” risk in public release. Meanwhile, the AI chatbot platforms Claude, ChatGPT, and Grok all suffered outages on Thursday at nearly the exact same time. But while xAI said the Grok outage resulted from issues at a Memphis data center, the causes of OpenAI’s and Anthropic’s outages are unclear.

The US has been using a high-energy laser to shoot down drones near the Mexico border as part of an initiative to adopt new-generation directed-energy weapons capable of detecting, tracking, and destroying drones with a concentrated beam of light. And as part of an Immigration and Customs Enforcement inquiry into the identities of protesters who entered a Minnesota church in March, Homeland Security Investigations agents have subpoenaed the outdoor retailer REI for information about every customer who bought a specific green beanie over the past two years.

Plus, research that revealed nine vulnerabilities with impacts on ATM encryption points to broader weaknesses in the software supply chain.

And there’s more. Each week, we round up the security and privacy news we didn’t cover in depth ourselves. Click the headlines to read the full stories. And stay safe out there.

OpenAI agents on an unauthorized tear hijacked a German website beginning in May to use it as a message board for communicating and collaborating with other agents, according to new research. The incident is reminiscent of the now infamous Hugging Face debacle in which OpenAI agents in a test environment went rogue and developed a vibrant message board for collaborating on attempting to escape their containment, before ultimately breaching the open source AI platform Hugging Face in July. The revelation of the May episode is particularly significant because OpenAI reportedly learned about it weeks ago but did not disclose it. Meanwhile, last week, the company finally released a long-promised postmortem of the Hugging Face incident that raised as many questions as it answered.

This week, a new dark-web service called Nexus started selling around 153 million driver’s licenses from the US and Canada, along with 10 million ID cards and millions more travel documents and international IDs, according to Brian Krebs, a longtime independent security reporter. Krebs was first alerted to the service after cybercriminals posted an example of the files and included his license. The tens of millions of records—which reportedly increased by 400,000 over 24 hours—appear to have come from an ID verification service, with the criminals behind the trove saying they have access to a “major” verification company. While it’s unclear which company exactly that may be, according to Kreb’s report, the Nexus service was taken offline shortly after he reported that FBI officials were investigating.

The US military has begun disabling the advertising identifiers that apps and advertising companies use to track phones and computers in an attempt to make it harder for foreign adversaries to use commercially available location data to track American forces overseas, Reuters reported Friday.

The changes follow years of disclosures that US forces deployed abroad have been targeted using commercially available location data. In 2024, a joint WIRED investigation with Germany’s Bayerischer Rundfunk and Netzpolitik.org obtained an advertising dataset that identified thousands of devices appearing at US military and intelligence sites, including an air base where US nuclear weapons are believed to be stored. At the time, Defense Department spokesperson Javan Rasnake told WIRED that the Pentagon was aware geolocation services could put personnel at risk and said service members in Europe were reminded to follow operational-security practices.

Now, the Air Force, Army, Navy, and US Special Operations Command say they have disabled advertising IDs on at least some military devices, with several of the changes taking effect only this year. It is still unclear exactly how these protections are being enforced. US senator Ron Wyden and Representative Pat Harrigan are now asking the Pentagon to investigate whether its safeguards are adequate.

A phone can look perfect on paper and still fail on your network. It might never reach 5G speeds, drop calls in your own neighborhood, or lose Wi-Fi Calling entirely. The cause is almost always the same: the phone’s radio bands do not match the ones your carrier actually uses where you live.

This guide shows you how to check that match before you buy a phone or switch carriers, using free official tools and a five-minute process. No technical background is needed.

What “Band Compatibility” Actually Means

A radio band is a specific slice of wireless frequency, identified by a number like Band 4 or Band 71. Carriers broadcast on a set list of these bands in your area. Your phone can only connect to a network if its hardware physically supports the bands that carrier is using.

This is a different question from whether a phone is “unlocked.” An unlocked phone has no software lock tying it to one carrier, so you are free to insert any SIM card. But carrier lock is a separate issue from band support. A fully unlocked phone can still be a poor fit for a carrier if its radio hardware was built for a different region.

There is a third layer too: some carriers, especially Verizon in the US, also require devices to pass network certification before they get full service, even when the bands line up. We cover that separately below.

What You’ll Need Before You Start

Method 1: Use Your Carrier’s Official Checker

This is the most reliable method, because it checks your specific device against that carrier’s live network data instead of a general spec sheet.

T-Mobile

1. Open T-Mobile’s BYOD checker in a browser.
2. Enter your phone’s IMEI number.
3. Read the result: Compatible, Partially Compatible, Incompatible, Locked, or Blocked.
4. If the result says “Partially Compatible,” your phone will work but may not get Extended Range LTE or full VoLTE calling. Treat this as a real limitation, not a technicality.

Verizon

1. Open Verizon’s compatibility check tool.
2. Enter your Device ID (IMEI, MEID, or ESN, depending on your phone).
3. Confirm the phone is unlocked. Verizon requires both hardware compatibility and an unlocked status before it will approve a device.

AT&T does not offer as complete a self-serve IMEI checker as T-Mobile or Verizon. For AT&T, cross-check with Method 2 below, then confirm with an AT&T store or support chat before you buy.

Method 2: Look Up the Manufacturer’s Official Band List

If you are checking a phone before you own it, the carrier tools above will not help, since you have no IMEI yet. Instead, look up the model’s published band list directly.

1. Search the phone’s exact model name on GSMArena’s spec pages.
2. Open the “Network” section on the phone’s page.
3. Find the 4G LTE and 5G band lists. Pay close attention to the region or model-variant notes; the same phone name sold in different countries often ships with different radio hardware.
4. Compare that list against your carrier’s published band list (most carriers post this on a coverage or network page).

This method takes a little longer than a carrier’s own checker, but it works for any phone, anywhere, before you spend any money.

Method 3: Cross-Check With a Dedicated Band Database

Two community-run tools focus specifically on band data and are worth a second look, especially for phones with confusing regional variants.

1. Kimovil’s frequency checker lets you pick a phone model and a country, then shows which of that country’s carrier bands your phone supports and which it is missing.
2. cacombos.com’s band database lists not just individual bands but which combinations of bands a phone can use at once, which affects real-world speed more than raw band count.

Both tools are free. Neither replaces an official carrier check, since band support alone does not guarantee a carrier will activate the device on its network.

Method 4: Check What Your Phone Is Actually Using Right Now

The methods above tell you what a phone is capable of. This one tells you what it is doing right now, on the network you already have.

1. On most Android phones, go to Settings, then About Phone, then SIM Status or Network to see basic connection details.
2. For a more detailed reading, install a dedicated app. Android Police’s band-checking guide recommends LTE Discovery or Network Cell Info Lite for this.
3. Open the app and grant location and phone-state permissions when asked; the app needs these to read live tower and band data.
4. Look for a band number and a signal strength reading. A signal at or above -90 dBm is generally usable; closer to -50 dBm is excellent.

This method only works after you already own the phone and have a SIM inserted. Use it to confirm a purchase decision, not to make one in advance.

Which Method Should You Use?

One More Wrinkle: eSIM-Only Phones

Some newer phones ship without a physical SIM slot at all. This changes how you activate service, but it does not change any of the band-checking steps above. An eSIM is just a different way of loading your carrier’s profile onto the phone; the radio hardware underneath still needs to match your carrier’s bands the same way a physical-SIM phone does. If you are deciding between the two SIM formats first, see our eSIM vs. physical SIM guide before you shop.

Don’t Stop at Bands: Two More Checks Before You Buy or Switch

Band compatibility is necessary, but it is not the whole picture. Skipping either of the following checks is where most costly mistakes happen.

IMEI blacklist status. A phone can support every band you need and still be useless if it was reported lost, stolen, or unpaid on a financing plan. Carriers share this status through GSMA’s IMEI database. This matters most for used or third-party marketplace purchases.

Carrier certification. Even a device with the right bands and a clean IMEI can be refused full service if the carrier has not certified that exact model for its network, something Verizon in particular enforces. This is separate from both the band check and the blacklist check, and none of the tools above test for it directly. The carrier’s own BYOD checker is the only reliable way to confirm it, which is one more reason to run Method 1 even after you have already used Methods 2 and 3.

If you are buying a factory-unlocked phone specifically to avoid these problems, our factory-unlocked phone buying guide covers the purchase side of this decision in more detail.

What Happens If You Get It Wrong

A band mismatch rarely means “no service at all.” More often, it shows up as partial problems: no 5G even in a strong coverage area, no HD Voice or Wi-Fi Calling, or a signal that vanishes as soon as you leave a city center. These issues are easy to blame on the carrier when the real cause is the phone’s hardware. The financial risk is real too: used-phone sellers often will not accept a return once a SIM has been activated, and some carriers charge a restocking fee on a device that turns out to be a poor match.

Quick Troubleshooting: Right Bands, Still No Signal?

If your phone passed every check above but still will not connect properly, the problem is usually a setting rather than the hardware.

• Confirm the SIM card is seated correctly and is the right size for the tray.
• Check Settings for a network mode option, and make sure it is not locked to an older standard like 3G-only.
• Reset network settings, or update the carrier APN manually if your carrier provides specific values.
• If none of that works and you are preparing to sell, return, or switch the device entirely, a full factory reset guide can rule out a software conflict as the cause.

If you are switching carriers mainly to save money rather than to fix a compatibility problem, our guide on keeping costs down when you switch covers that side of the decision.
