I'm in a Mandalay Bay exhibition hall for CES 2019 and spot a guy holding a guitar. He's wearing a sleek black smartwatch on his wrist that lights up at regular intervals with a green light ring. The guitarist turns the edge of the watch face and the pulsing light speeds up. Then he turns it the other way and the pulse slows down.

It turns out the guitarist is Florian Simmendinger which has to be the best name there is for the CEO of a company that makes smartwatches for musicians. Simmendinger founded the company Soundbrenner and the watch he is wearing is a new smartwatch called the Soundbrenner Core.

The pulsating light that caught my attention is part of the watch's metronome. It lights up to a set tempo. But when I try the watch on, I notice it also vibrates. Feeling the beat as a vibration on my wrist is much more intuitive than listening to the tempo from an old wooden metronome. I turn the watch face like Simmendinger did to adjust the metronome tempo.

Soundbrenner Core is the follow up watch to the Soundbrenner Pulse. The main difference is that the Pulse only has the vibrating metronome feature while the Core also has a tuner and decibel meter.

The Core can double as a magnetic contact tuner for tuning a guitar, bass or violin. The entire watch body twists off the wristband base and you touch it to your instrument's pegs. The Core tunes by measuring the vibration of the strings. This means that no matter how loud your surroundings are that you can accurately tune your strings to the correct notes.

Also, the easy and bold way the watch transforms into a tuner seems like something Tony Stark designed if he played guitar.

There is a built-in decibel meter that can be used to keep your live performance from being too loud or soft. Really the only thing missing from the Soundbrenner Core is a really wide leather band and giant silver buckle.

The Soundbrenner Core starts out at $229 which converts roughly to £180, AU$320 and is available for preorder. The Soundbrenner Pulse is $99 which converts roughly to £80 , AU$140 and can be purchased now.
