9x9x3cm is the total size and they weigh 213 grams. Once split they can be placed up to 15 feet apart and give a good amount of sound. 3.5x2.5x1.5cm is the size of each earbud that fits inside the back of each speaker.

Also in the package are other sizes of gels to fit the buds a short USB ‘C’ to USB lead to charge the speakers, a loop through cord and a User Guide.

To pair should be easy - for me anyway it was not – according to the User Guide a press on the single button for ten seconds, I had to try this several times before my SmartPhone showed the Duolink as an item to pair once it was shown it worked fine and automatically reconnected even after several days without connection.

So to check I tried my backup phone and again it was several attempts before it showed up but again even after a week pulling the speakers apart and starting to play music it played automatically immediately.

I was sent an early sample so maybe this has something to do with it. 

I found that playing music through my phones speaker and then pulling the Duolink speakers apart and six seconds later the sound was switched off from the phone and started playing through the Duolink, with the speakers separated extract the earbud from the rear of each speaker and the sound automatically plays through the bud.

Should you wish you can put the speakers together and the music still plays through them.

The User Manual shows where to touch on the back of the bud for things like increasing and decreasing volume, back a track, forward a track, play and pause, answer or end a call and perhaps most impressive activate the voice assistant by a long press. All these functions worked correctly.

The Bluetooth settings on your phone tell you how charged the battery is - 90 minutes for a full charge from empty - you can also manually disconnect the speakers/buds from the Bluetooth settings page. I never quite got the 15 hours battery time between charges but it was always into double figures.

The buds have a 40mAh charge while the speakers are ten times that 400mAh.

While I have reviewed better buds and also better speakers the idea of having both in a single unit is both an innovative and novel idea and the sound quality was reasonable and the ease of accessing the voice assistant could be very useful when in areas where you might not want to take your phone from your pocket.

I was sent the dark blue unit but it is also available in red or white.
