Flying for hours on end is the bane of my existence. From sitting in a tiny seat for hours to the highly communal restroom, I must keep myself distracted throughout the flight to keep from going crazy. I try my best to work, sleep, or read the whole flight because watching movies on a plane just isn’t the most luxurious experience.

Also: I expected Samsung’s new flagship earbuds to bore me, but I fell in love with them instead

But flying on an airplane is an apt opportunity to catch up on your movie watchlist, even if the plane entertainment system can thwart your plans. You have two options: use the airline-provided “headphones” and hear everything on the plane except your movie, or use your headphones and be tethered to the back of the person in front of you. 

To avoid either scenario, I’ve been testing TwelveSouth’s latest Bluetooth adapter, the AirFly Pro 2. The company sent me the latest AirFly adapter to test on my flight recently, and if you’re a frequent flyer and a movie buff, here’s my verdict after hours of use.

The original AirFly was one of Twelve South’s most popular products, and for good reason. It’s a multi-use Bluetooth adapter that wirelessly connects headphones to airplane entertainment systems, gym equipment, and gaming consoles, as long as the host devices have a 3.5mm adapter.

The new AirFly Pro 2 has all the most desirable features from the previous AirFly model — dual headphone connection, physical volume buttons, a lengthy battery life, and auxiliary input compatibility — and much more.

On my flight from Atlanta to New York last week, I tucked the AirFly Pro 2 into my personal bag and plugged it into the plane entertainment system’s 3.5mm headphone jack. After turning it on, I put my Sonos Ace into pairing mode and watched “Moana 2.” You can connect two headphones to the AirFly Pro 2, so two people can watch the same media on the in-flight entertainment system.

The movie sounded terrific through my headphones. I turned on noise cancellation and spatial audio with head tracking to drown out the plane engine noises and enhance my listening experience. In wired mode, most wireless headphones can’t access their wireless audio settings, allowing external noises to leak in. With the AirFly Pro 2, this wasn’t an issue.

Pairing the dongle was rather simple. I pressed my headphones’ power button until they entered pairing mode, then held the AirFly’s “Pair 1” button, and I was all set.

The AirFly Pro 2 has an upgraded Qualcomm chip inside, which improves audio quality, provides more stable wireless connections, and reduces power consumption.

On the right side of the dongle is a switch to toggle between transmit (TX) mode and receiver (RX) mode. In TX mode, the AirFly transmits audio from an analog source, like an in-flight entertainment system, to your headphones. RX mode receives audio from your phone to play through the aux-in port of a car, boat, or stereo system.

Also: Bluetooth’s latest wireless audio push could solve a connectivity problem we’ve all dealt with

With 25 hours of battery life, the AirFly Pro 2 can last you through a round-trip trip across the US. And when you need to charge it, there’s a handy USB-C port for that.

ZDNET’s buying advice

The Twelve South AirFly Pro 2 is a wonderful travel companion for frequent flyers. It takes up little space in your bag and makes an otherwise unenjoyable listening and watching experience much better. Although it’s marketed for in-flight use, you’ll get your money’s worth with its aux-in compatibility with non-Bluetooth audio devices and systems.

If you’ll likely use this product often, I recommend spending the $60 for a reliable and high-quality product. However, if you want a cheaper option, Twelve South offers the AirFly SE, but it doesn’t have aux-in compatibility or dual headphone connectivity.

Google Maps has a long list of hidden (and sometimes, just underrated) features that help you navigate seamlessly. But I was not a big fan of using Google Maps for walking: that is, until I started using the right set of features that helped me navigate better.

Add layers to your map

See more information on the screen

Layers are an incredibly useful yet underrated feature that can be utilized for all modes of transport. These help add more details to your map beyond the default view, so you can plan your journey better.

To use layers, open your Google Maps app (Android, iPhone). Tap the layer icon on the upper right side (under your profile picture and nearby attractions options). You can switch your map type from default to satellite or terrain, and overlay your map with details, such as traffic, transit, biking, street view (perfect for walking), and 3D (Android)/raised buildings (iPhone) (for buildings). To turn off map details, go back to Layers and tap again on the details you want to disable.

In particular, adding a street view and 3D/raised buildings layer can help you gauge the terrain and get more information about the landscape, so you can avoid tricky paths and discover shortcuts.

Set up Live View

Just hold up your phone

A feature that can help you set out on walks with good navigation is Google Maps’ Live View. This lets you use augmented reality (AR) technology to see real-time navigation: beyond the directions you see on your map, you are able to see directions in your live view through your camera, overlaying instructions with your real view. This feature is very useful for travel and new areas, since it gives you navigational insights for walking that go beyond a 2D map.

To use Live View, search for a location on Google Maps, then tap “Directions.” Once the route appears, tap “Walk,” then tap “Live View” in the navigation options. You will be prompted to point your camera at things like buildings, stores, and signs around you, so Google Maps can analyze your surroundings and give you accurate directions.

Download maps offline

Google Maps without an internet connection

Whether you’re on a hiking trip in a low-connectivity area or want offline maps for your favorite walking destinations, having specific map routes downloaded can be a great help. Google Maps lets you download maps to your device while you’re connected to Wi-Fi or mobile data, and use them when your device is offline.

For Android, open Google Maps and search for a specific place or location. In the placesheet, swipe right, then tap More > Download offline map > Download. For iPhone, search for a location on Google Maps, then, at the bottom of your screen, tap the name or address of the place. Tap More > Download offline map > Download.

After you download an area, use Google Maps as you normally would. If you go offline, your offline maps will guide you to your destination as long as the entire route is within the offline map.

Enable Detailed Voice Guidance

Get better instructions

Voice guidance is a basic yet powerful navigation tool that can come in handy during walks in unfamiliar locations and can be used to ensure your journey is on the right path. To ensure guidance audio is enabled, go to your Google Maps profile (upper right corner), then tap Settings > Navigation > Sound and Voice. Here, tap “Unmute” on “Guidance Audio.”

Apart from this, you can also use Google Assistant to help you along your journey, asking questions about your destination, nearby sights, detours, additional stops, etc. To use this feature on iPhone, map a walking route to a destination, then tap the mic icon in the upper-right corner. For Android, you can also say “Hey Google” after mapping your destination to activate the assistant.

Voice guidance is handy for both new and old places, like when you’re running errands and need to navigate hands-free.

Add multiple stops

Keep your trip going

If you walk regularly to run errands, Google Maps has a simple yet effective feature that can help you plan your route in a better way. With Maps’ multiple stop feature, you can add several stops between your current and final destination to minimize any wasted time and unnecessary detours.

To add multiple stops on Google Maps, search for a destination, then tap “Directions.” Select the walking option, then click the three dots on top (next to “Your Location”), and tap “Edit Stops.” You can now add a stop by searching for it and tapping “Add Stop,” and swap the stops at your convenience. Repeat this process by tapping “Add Stops” until your route is complete, then tap “Start” to begin your journey.

You can add up to ten stops in a single route on both mobile and desktop, and use the journey for multiple modes (walking, driving, and cycling) except public transport and flights. I find this Google Maps feature to be an essential tool for travel to walkable cities, especially when I’m planning a route I am unfamiliar with.


More to discover

A new feature to keep an eye out for, especially if you use Google Maps for walking and cycling, is Google’s Gemini boost, which will allow you to navigate hands-free and get real-time information about your journey. This feature has been rolling out for both Android and iOS users.
