Sometimes a device which goes completely against expectations crosses our review desk. One such: the Sony Xperia Ear Duo earphones.

What are they?

My expectations were that the Sony Xperia Ear Duo was just one more set of wireless earbuds. They are earbuds, kind of. They use Bluetooth to communicate with your smartphone – both iOS and Android. And they come in a disc-shaped case that’s 25mm thick and 89mm in diameter.

The case not just holds them but charges them. It carries enough charge to refill them three times. The earpieces snap into position with certainty, pulled by magnets. You charge the case via a USB Type-C socket. As usual, it’s up to the purchaser to provide the power supply. Also provided is a USB Type-C charge cable.

So, I figured I’d plug them into my ears and start listening. But I opened the case and found a rather more complicated story. First, instead of diminutive buds, they were relatively substantial devices. They each consist of a largely rectangular block with a bent tube emerging from its end. At the end of each tube was a ring of silicon, not the usual closed ear tip. Each block measures around 50mm long by 17mm wide and 10mm thick. Each earpiece weighs 10.6 grams.

There were no apparent controls on the rectangular block. Putting them on my ears looked daunting. As we’ll see, I did master that later.

I went to Sony’s website and looked under earphones to findout more about the Sony Xperia Ear Duo. And I couldn’t find it. But then Irealised that there are two brands mentioned in that name: Sony and Xperia. Ifound them on the Sony Mobile website, which is where all the Xperia products are located.

It was then that I approached some semblance of understanding. Most earphones I review are principally for listening to music. And most of them also have a hands-free function. But the Sony Xperia Ear Duo are principally supercharged hands-free devices, with which you can also listen to music and such. They are suitable for wearing for extended periods and generally not interfere with your life and work while you’re wearing them. That silicon ring performs the function of locating the tiny sound transducers over your ear canals.

Actually, the real mini-drivers are inside the block. The tube is called a “spatial acoustic conductor”. It seems that this “pipes” the sound into your ears. The sound of the outside world passes through the hole at the centre of each ring. You can live life normally, except with the body of the Sony Xperia Ear Duo earphones tucked behind each ear.

Spare locating rings are included. One was larger than those pre-installed. One was smaller. Weirdly, there was only one of each, and both were in a tiny plastic bag labelled “L”, for what I imagine means “Large”.

Your assistant

I said that the Sony Xperia Ear Duo earphone are “supercharged hands-free devices”. That’s because, in addition to allowing you to manage calls, they work in conjunction with the Sony Xperia Ear Duo app to do much, much more. I used the Android version. They work with both Google Assistant on Android devices and Siri on iOS devices. But the “Daily Assist” function works only with Android.

Daily Assist does things like tell you the time each hour, warns you of forthcoming appointments and reads out texts and emails. When you install the app and get it going, be prepared to grant quite a few permissions so it can read your calendar, contacts, email and many other things. It also read my WhatsApp messages, I discovered. I’d guess it would work with any other text-based communications app that you might have.

Of course, it isn’t always very smart. When emails came in it would read them out to me, including the disclaimers at the foot of some of them, contact phone numbers and so on.

Options

The app/hardware combination is highly configurable. There are controls on the Sony Xperia Ear Duo earpieces: the surface is touch sensitive. Slide your finger on one for volume control. Tap it to play or pause playback or answer calls. A tap also stops the earphones from reading those interminable emails.

The right earpiece can be configured to respond to different taps and holds to do things like invoking “Daily Assist”, reply to a message, warn of upcoming events or simply to announce the current time.

Furthermore, you can use head gestures. These are also configurable. A shake of the head can say “No” to the Assistant, and a nod can say “Yes”. The shake can refuse a call, and the nod can answer it. You can skip tracks by turning your head to the right, or backwards by turning it to the left. I found that enabling that last facility led to some unexpected track skipping. Apparently I turn my head more than I thought I did.
