Got Bluetooth problems like a glitchy mouse or an unreliable keyboard? Maybe a screwy trackpad or poor headphone connection? Any of those problems could result from a glitch in your Mac’s Bluetooth radio. Maybe you’ve already tried everything — unpairing your devices, resetting them or even creating a pristine new user account on your Mac solely for troubleshooting purposes.

You may even know about the hidden Bluetooth menu that appears when you option-click on the Bluetooth menu bar icon. But did you know that there’s another, deeper, super-hidden menu with extra troubleshooting tools? There is. Here’s how to fix Bluetooth problems when nothing else seems to work.

In a rare moment of collaboration, Apple and Google said Friday they have teamed up to create a contact-tracing program that uses smartphones to stop the spread of COVID-19.

The privacy-focused solution created by the companies will use anonymous Bluetooth “chirps” from phones as a way to tell where an infected person has been and who they’ve come in contact with.

Bluetooth LE Audio, a new version of this wireless standard, sets out to increase the battery lives of audio devices like Apple’s AirPods. It will provide high-quality sound even at low data rates, reducing the power requirements of tiny in-ear headphones.

Nuheara’s Bluetooth earbuds help users better hear what’s going on around them, as well as play music and podcasts. The latest version adds active noise cancellation, and comes at a considerable price drop.

The new IQBuds2 Max garnered innovation awards in three categories at CES 2020.

AirFly Pro can wirelessly connect your AirPods to a plane’s entertainment system. Or the machines at your gym. If it has a 3.5 mm audio jack, this Bluetooth adapter lets it communicate with your AirPods. Even two pairs at once.

And the same easily-pocketable gizmo can connect your iPhone to a car stereo’s AUX port to play music off your iPhone.

I tested both these features — find out how well they work in this AirFly Pro review.

A black-and-silver Magic Keyboard, Mouse 2 and Trackpad 2 debuted in Apple’s product lineup today, but only a fortunate few can order them. As it stands now, these accessories are only available for people who also buy a 2019 Mac Pro.

But that’s likely to change soon.

In iOS 13, you can share songs and watch movies with a friend, with each of you using your own AirPods. The new feature is called Audio Sharing, and it lets you instantly — and temporarily — pair a second set of AirPods to your iPhone or iPad. It’s like the olde schoole method of using a headphone splitter to plug two sets of headphones into one jack socket, only way more expensive and fancy.

Here’s how to use it.

Problem: You have a kick-ass stereo, or a pair of excellent studio monitor speakers, and you want to hook up your iPhone to listen to some music. Only you don’t want to dig out the headphone dongle and plug in a cable.

Solution: The Kali Audio Bluetooth Module. It hooks up to your speakers via cable, adding a Bluetooth receiver that lets you get the music out of your iPhone or iPad. It seems simple, and it is. But it’s also super-duper handy.

A Bluetooth LE security flaw could let malicious actors discover people’s iPhone numbers using Apple’s file-sharing AirDrop feature.

An attacker would need to create a phone number database for a specific region. Using a special script, they then could collect information on users who tried to AirDrop a file.

AirPods might just be the most convenient wireless headphones money can buy. But because they rely on Bluetooth, you can’t use them with everything. This little adapter from RHA hopes to change that.

The Wireless Flight Adapter plugs into any 3.5mm headphone jack to make it wireless. It’ll work with in-flight entertainment systems — as its name suggests — as well as the Nintendo Switch, TVs, old iPods, and more.
