I don’t get on a plane unless I am wearing Bose QuiteComfort 20 Noise Cancelling earbuds. These squeeze into a tiny super-lightweight pocket when off (unlike the headphone variety), and are simply the best noise cancelling apparatus, period. I routinely wear them the entire duration of a 13-hour flight. I arrive far more refreshed. — KK

I like to listen to podcasts in bed. I also sleep on my side, so earbuds and headphones hurt my ears if I use them. I bought the CozyPhones Sleep Headphones ($18), which is a headband with 1/8” thick cushioned headphones inside. They are comfortable and they roll up for travel. — MF

I use a squid outlet when I travel. In cheap lodging there is often barely one accessible power outlet on the wall and I have lots of things to charge, from camera batteries, to a laptop, to more than one phone. That’s just me. With a travel companion there’ll be even more items to charge. A squid splits the power to four flexible outlets. The flexibility gives more room for devices than a simple power strip. This 2-pack Squid is the cheapest, lightest, smallest one I’ve found. — KKaudiobooks

I’ve tried many ways to extend Wi-Fi through my house. Powerline networking, which creates networks through electrical wiring, works the best. TP-Link has a $58 kit with 2 units. One unit plugs into your wall outlet and router. The other unit can be plugged into any wall outlet in your house to provide Wi-Fi in that area. — MF

The $9 AmazonBasics Adjustable Tablet Stand was just what I was looking for in a kitchen countertop iPad stand. It’s made of sturdy plastic, adjusts quickly, and doesn’t skid or wobble. It can hold any size tablet — even smartphones. — MF

I bought the Amazon 7” Fire Tablet for $40. It’s great for reading ebooks, listening to audiobooks, and watching Netflix and Amazon Prime videos. But I also followed the instructions to install the Google Play Store, so I can add Android apps not available from the Amazon App Store. Now I have Google Maps, Gmail, Slack, Feedly and more on the tablet. — MF

You can wake up Alexa by using the wake command “Computer” as in Star Trek. Go to the Alexa app on your phone. Right-swipe to open a panel with settings choices. Pick your device and scroll down to wake commands. You have a limited choice of four words, including computer. There is a movement to make that command a common voice interface among all devices. Are you listening, Siri, Cortana and Google? — KK

We installed AI into our kitchen to get a glimpse of the future. Now we talk to Alexa, and ask it to do all kinds of things. “Alexa, what is on my calendar today?” “Alexa, add granola to my shopping list.” The cheapest way to do this is not with an Echo (size of wine bottle), if you already have speakers, but with the Echo Dot. Size of a large hockey puck, it’s always on, waiting for your command. And it will get upgraded over time. — KK
