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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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.” Â
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.Â
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.

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded
The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”
President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.
The White House later clarified that the super PAC â MAGA Inc. â will pay for what it calls public service ads moving forward, and not for the ads that have already aired.
Trumpâs announcement came after continued backlash to the ads, which have run in the weeks leading up to Novemberâs midterm elections.
Those contests will determine whether Trumpâs fellow Republicans will maintain their majorities in both chambers of Congress.
Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying âAmerica will never be a communist country.â
âThe Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,â Trump said in a post on Truth Social on Monday.
âThis is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,â Trump said.
AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.
Trumpâs announcement came three days after The New York Times, citing people familiar with the matter, reported that âTrump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.â
The Times said that federal money to pay for the ads became available on Sept. 19, âwhen the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.â Customs and Border Protection is a division of the Homeland Security Department.
Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, âThe advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of âa general propaganda effort designed to aid a political party or candidates.ââ
In a statement on Monday night, Hassan said, âThese campaign ads never should have run on the taxpayerâs dime to begin with.â
âThey were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,â said Hassan. âThereâs a lesson here: We canât underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.â
Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.
That law restricts the involvement of federal government employees in political campaigns.
A White House spokesperson defended the ads in a statement in late September to CNBC, calling them âpublic service announcementsâ intended to remind âAmericans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.â
âThe ad is educational and unapologetically patriotic. We should be proud of our country,â the spokesperson said.
MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.
MAGA Inc. has spent at least $57 million this election cycle, according to CNBCâs analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from IranâBacked Houthi Fighters in Major Offensive
Yemenâs government forces said they have retaken the Red Sea port of Mokha from Iranâbacked Houthi fighters, weakening the militantsâ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.
Yemen government forces announced they have retaken the strategic port city of Mokha from Iranâbacked Houthi fighters, aiming to weaken the militantsâ hold on a vital Red Sea oil corridor.
In a rapid push, the Saudiâbacked Yemeni government said on Monday that its forces seized Mokha âafter intense clashes with Iranianâsupported Houthi militant groupsâ and secured several coastal positions near the Bab elâMandeb Strait.
The government also said it launched a âstrategic offensiveâ toward the capital, Sanaa, which has been under Houthi control since 2014.
Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.
Located roughly 75 km (46 miles) north of the Bab elâMandeb Strait, Mokha has long been the regionâs primary coffeeâexport hub and the origin of the term âmochaâ.
Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iranâbacked group could gain sway over the Bab elâMandeb Strait.
Iranâs shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.
On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact âdeterrence measuresâ and to swiftly deploy troops to bolster the oilârich kingdom and counter Houthi attacks in Yemen.
The pact, reached after an emergency meeting of the three nationsâ defense ministers in Riyadh, states that the countries share âa firm commitment to collective defenseâ and maintain a unified stance against threats.
Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdomâs aviation authority.
In a Tuesdayâmorning socialâmedia statement, Saudi Arabiaâs General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.
GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdomâs civil aviation system.
Energy market nervousness âlikely to persistâ
Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.
International benchmark Brent
“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.
“Such nervousness is likely to continue until there is evidence of progress in a USâIran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab workerâs death
According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.
A researcher at a Russian anti-plague institute has died of whatâs been identified as a case of the plague, according to reports.
Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.
The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasnât been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.
âAll of the patientâs contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,â the WHO said.
What is the plague and how does it spread?
Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. Itâs caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.
Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.
The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.
As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesnât travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.
The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.
âPotentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,â Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. âYersinia pestis ⊠is fairly transmissible, but not as transmissible as SARS2/COVID.â
Whatâs happening with the suspected case in Russia?
According to Russiaâs public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with âpneumonia of unknown aetiology.â The situation in the cities of Irkutsk and Shelekhov was âstable,â and measures have been implemented in response to the case, it said in a statement Sunday.
Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.
CNBC has not been able to independently verify the reports. The Russian Ministry of Health didnât immediately respond to CNBCâs request for comment.
According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. âBut there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,â he added.
A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that âif Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.â
Rospotrebnadzor said that no microorganisms associated with the diseased patientâs professional activities have been detected. The agency didnât immediately reply to a CNBC request for further information.
The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
