Bluetooth 6.0: What You Need to Know About the Future of Wireless Headphones

Bluetooth got a major upgrade, and it’s already showing up in phones and headphones. Here’s what to expect and what we’re still waiting for.

The Bluetooth Special Interest Group announced version 6.0 of the near-ubiquitous wireless technology in Sept. 2024, adding some major new features that aim to improve Bluetooth’s reliability, security, smoothness and efficiency. It might even get you a greater range between your headphones and phone, as well as longer battery life. 

We’re finally seeing devices arrive with Bluetooth 6.0, including phones from Apple and Google, as well as headphones and earbuds. Here’s what you need to know about Bluetooth 6.0 and how it will affect wireless connectivity for years to come. 

Main improvements of Bluetooth 6.0

Latency

Latency is the time between an audio signal being sent and when you actually hear it. The higher the latency, the more annoying it can be — think of when the sound lags behind the video in movies or games. Most Bluetooth (5.0 and newer) devices have latency somewhere between 50 to 100 milliseconds, depending on gear and configuration, which is noticeable to most people. 

Bluetooth 6.0’s new isochronous adaptive layer, or ISOAL, allows devices to break up audio data into smaller chunks for quicker processing. In theory, this has the potential to reduce latency, and it’s possible that we might see latency under 10 milliseconds under ideal conditions, such as close range, no obstacles and no interference. 

We expect that under real-world conditions, the majority of setups will operate at a latency of around 20 milliseconds, which would still represent a significant improvement over Bluetooth 5.x. 

Location tracking and security

One of the new spec’s most buzzworthy features is called Channel Sounding, which provides a significant improvement in the accuracy of device location tracking. It relies on a back-and-forth exchange of data packets between connected devices and a combination of time stamps and frequency analysis, rather than the old, less accurate method of just measuring relative signal strength. 

Channel Sounding is a boon for Apple’s Find My and its Google and Samsung equivalents, offering location accuracy down to approximately 10 centimeters, along with improved resistance to obstacles and interference. It also enables enhanced security for Bluetooth lock systems using a combination of encryption, randomization and location cross-referencing to ensure some random person isn’t unlocking your car or front door. 

Power efficiency and pairing speed

The same features that reduce latency also help with power efficiency: Everything behaves intelligently to use more power for keeping audio and video in sync for things like gaming, and less power for less intensive applications like audiobooks. This flexibility is especially crucial for wireless earbuds, which require the most effective power management due to their compact size. 

The process of scanning for nearby Bluetooth devices is also being upgraded, with decision-based advertiser filtering and monitoring. Advertising in this case doesn’t refer to selling you products. Basically, it’s a set of headphones broadcasting, “I’m a headset, and I’m nearby and ready to connect.”  

Instead of constantly shouting, “Is anyone there?!” to see if there’s anything nearby to connect to, Bluetooth 6.0 devices will keep track when previously paired devices go in and out of range. This should save precious battery life, make pairing quicker and provide smoother multipoint switching.

What Bluetooth 6.0 doesn’t do

Improved Bluetooth sound quality (maybe)

Were you waiting for reliable, wireless lossless audio transmission from your phone to your headphones? Still not there yet. 

Astute readers who note that CD-quality lossless audio transmission requires 1.4Mbps of throughput speed may wonder why Bluetooth 6.0’s theoretical 3Mbps isn’t enough. It’s because much of Bluetooth’s bandwidth is taken up by overhead — a bunch of ancillary data that’s required for secure Bluetooth connections that has nothing to do with audio. While there are some codecs that promise high-quality wireless audio, lossless CD-quality audio remains elusive.

Bluetooth 6.0 does bring the optional long-discussed LC3plus codec, which can transmit up to 24-bit and 96kHz audio. However, unlike “regular” LC3, this is an optional codec that has a separate licensing fee. That means there will be limited adoption compared to the more popular codecs. Remember, both your device and headphones must be compatible with LC3plus for it to work. How well it works and whether it can reliably transmit 24/96 in the real world remain to be seen.

A future incremental revision of Bluetooth 6.0 promises to add a high-data-throughput feature that will open up usable bandwidth for lossless streaming, potentially by using other frequency bands besides the crowded 2.4GHz band, to achieve speeds of up to 7.5Mbps. That should provide enough headroom to enable high-res audio streams, though it’s unclear if manufacturers will adopt the right codecs for lossless Bluetooth audio via headphones. Given past and current adoption rates for different Bluetooth codecs, it is unlikely to be Apple, and this technology will instead first find its way into lesser-known Android phones.

Where to find Bluetooth 6.0 right now

If you want to get a head start on Bluetooth 6.0 compatibility, there are a handful of devices already shipping (though not all of these are available in the US).

Supreme Court permits certain Trump mail-in voting restrictions before midterm elections

The Supreme Court has temporarily blocked a lower court ruling that prevented the Trump administration from implementing new restrictions on mail-in voting, allowing the administration to proceed with its plan to impose new requirements on states ahead of the midterm elections.

The Supreme Court on Monday sided with President Donald Trump for now in his effort to impose sweeping new restrictions on distributing mail ballots, putting on hold a lower-court ruling that had blocked key parts of the plan ahead of November’s midterm elections.

The justices, over three dissents, paused a ruling by U.S. District Judge Indira Talwani in Boston that prevented the Trump administration from carrying out portions of a March executive order involving the U.S. Postal Service and voter eligibility lists. The court’s three liberal justices dissented.

But the decision does not immediately allow the Postal Service to put its new mail-ballot system into effect.

A separate nationwide injunction issued Aug. 11 by U.S. District Judge Indira Talwani in Boston still blocks USPS from implementing the new procedures for the Nov. 3 elections. The administration would have to overcome that order as well.

The distinction was central to the Supreme Court’s decision.

The majority said Trump’s executive order itself does not require states to change how they conduct elections. Instead, it directs federal agencies to develop policies that could later impose requirements on states. Because those policies had not yet been implemented when 23 states and Washington, D.C., challenged the order, the court said the challenge was premature.

The justices stressed they were not deciding whether Trump’s order or the policies developed under it are ultimately legal.

“The Court’s disposition of this application does not mean that any measure taken by the Government to implement the Order will necessarily be lawful,” the majority wrote. “On that score, time will tell.”

The Postal Service last week finalized rules intended to carry out part of Trump’s order, including new requirements involving ballot envelopes, barcodes and information states must provide USPS. Those rules remain blocked by Talwani’s separate injunction.

The case now returns to the 1st U.S. Circuit Court of Appeals as the underlying legal fight continues. Some states have already started preparing to send ballots to military and overseas voters in early September.

Trump targets Iran’s trade lifelines — here are the countries most exposed

Washington’s threat of “economic D-Day” collides with a small group of governments that account for most of what remains of Iran’s foreign trade.

The U.S. announced an “economic D-Day” campaign Monday to isolate Iran from the global economy, threatening penalties against “enablers” that continue doing business with Tehran.

The move is part of Washington’s bid to sever the trade lifeline that has sustained Tehran’s economy through nearly six months of war.

While enforcement details are sketchy, the threat could still put the U.S. on a collision course with some of Tehran’s major trade partners.

China

China is the biggest buyer of Iranian oil and serves as a crucial link to the global economy for Tehran, accounting for about 90% of its oil exports, according to the U.S. government.

China reported $9.96 billion in bilateral trade with Iran in 2025, excluding the roughly $31.2 billion in unreported Iranian crude oil exports to China that year, according to the U.S.-China Economic and Security Review Commission.

Independent Chinese refiners take in the bulk of it, often rebranded as Malaysian or Indonesian crude and settled through intermediaries outside the dollar system, according to Kpler. The U.S. Treasury has sanctioned several of those refineries this year for Iranian oil purchases, while sparing Chinese financial institutions.

Beijing has openly opposed U.S. sanctions against Iran, arguing that economic pressure will not resolve the disputes. In May, China ordered domestic firms to disregard U.S. sanctions on five refiners linked to the Iranian oil trade.

While Beijing is unlikely to push back directly on Washington’s sanctions push, it will “quietly step up compliance” among state banks and oil companies to avoid getting caught in the net, said Dan Wang, China director at Eurasia Group, pointing to “a dichotomy between the official statement and the private practice.”

“Chinese authorities care more about dollar access in financing and market entry to the U.S.,” she said.

United Arab Emirates

The Emirates, located just 50 miles from Iran across the Persian Gulf, has long been a major trading hub for Iran.

The bilateral trade amounted to around $28 billion in 2024, when the Emirates was its largest source of imports, contributing over 30%, according to the World Trade Organization data. The UAE was also Iran’s third-largest export destination, making up 12% of its shipments, totaling more than $7 billion.

That relationship hit a snag last week as the UAE moved to suspend all trade and financial transactions with Iran, following two ballistic missiles fired toward Emirati territory, one of which targeted UAE-owned tankers.

Iran has relied on UAE banks and its financial system to access the world economy through illicit, often murky transactions, and cutting off Iran would require more forceful actions from Emirati authorities to crack down on opaque financial and trading activity, according to U.S.-based think tank The Washington Institute.

“The majority of Iran’s transshipment, smuggling, and shadow banking activity takes place in Dubai, so Washington must do what it can to help the UAE’s national leaders in Abu Dhabi convince and cajole Dubai’s leaders to play ball,” Matthew Levitt, a former U.S. Treasury official, wrote in a note on Monday.

Turkey

Turkey maintains significant commercial ties with Tehran, importing Iranian natural gas and exporting manufactured goods south.

The Turkey-Iran bilateral trade reached $5.7 billion in 2024, according to the Turkish Ministry of Foreign Affairs, with Ankara exporting mostly machinery and parts, chemical and agricultural products, while importing energy products from Tehran.

Meanwhile, under a 25-year gas supply contract between the two countries that expired at the end of July, Turkey’s imports of Iranian gas spiked this year while Iran’s share of Turkey’s total natural gas imports rose to 18.6%, according to local media.

While Ankara has sought to diversify toward other suppliers, expanding pipeline imports from Azerbaijan and Russia, it has, so far, not signaled that it intends to cut Iran off.

Iraq

Iraq, dependent on Iranian electricity and gas, has historically traded billions with Tehran.

Iran renewed a five-year contract in March 2024 to supply Iraq with up to nearly 660 billion cubic feet of natural gas a year, and electricity imports from Iran accounted for more than 30% of its electricity generation in 2023, according to the U.S. Energy Information Administration.

Iraq-Iran trade reached more than $10 billion in 2025, according to Reuters, with Tehran exporting food, consumer goods and other products to the Iraqi market. The trade has dwindled this year amid increased security risks in the region and intermittent disruptions along border crossings since the war started in late February.

Iraq reportedly pays Iran around $4 billion to $5 billion a year for natural gas for electricity generation. The fresh U.S. sanctions could curtail Baghdad’s payments for Iranian energy.

India

India, among Iran’s top five trading partners, has seen its bilateral trade with Iran fall in recent years to around $1.6 billion in the year ending March 2026, according to India’s Department of Commerce, down from $2.3 billion in the year through to March 2023.

New Delhi primarily exports rice, tea, sugar and pharmaceuticals to Iran, and imports dry and fresh fruits from Iran.

In April, India resumed importing crude oil from Iran following a seven-year halt, after the U.S. temporarily lifted sanctions on Iranian crude exports.

But those trades now will be tested if Washington makes good on its threat to sanction any entity, including Indian refiners, that have procured Iranian energy.
