Smartwatch Smartwatch

Just a practice tool. Or your daily watch.

Use Core 2 just during music practice. Or wear it as your daily watch and always stay connected to your smartphone. It's up to you!

Core 2 displays notifications and calls, and while you're listening to music, you can use it as remote to switch songs or adjust volume.

It also comes with an alarm clock, timer and stopwatch app.

How the volume alarm works

Your Core actively listens to the sound levels throughout the day. Once the volume reaches a risky level, it will alert you.

To know what's risky, we follow the recommendations of the World Health Organization:

  • 80 dB: 5 hours 30 minutes per day
  • 85 dB: 1 hour 45 minutes per day
  • 90 dB: 30 minutes per day
  • 95 dB: 10 minutes per day

The Core 2 can only measure sound levels above 70 dB and uses A-weighting.

Don't worry - we respect your privacy and no audio is ever recorded or stored.

If you don't like this feature, you can turn it off any time!

Magnetic contact tuning

In addition to the default MEMS microphone tuner, you can unlock contact tuning by purchasing one of our magnetic accessories.

We offer a tuner clip, that can be easily swapped between instruments. Or a 3-pack of magnetic tuner mounts, that are small and discreet and can be left on your instruments long-term.

Contact tuning is quick, accurate and unaffected by ambient noise. It works with any guitar, bass, ukulele, and violin.

The most useful features for me are the contact tuner and dB meter

I'm a music teacher and I loved using the Core at work. Tried to tune a guitar, a ukulele and a bass, everything worked perfectly! I have also set my watch to alarm me if the dB gets too loud where I am, and it has been a saviour at different places.

Effective and Convenient… Soundbrenner Core Steel

I am just starting out with guitar but the Core Steel is such an amazing tool. It makes practice fun, keeps me consistent, and helps me to just relax and enjoy time with my guitar. Can't wait to use it while performing for my family!

Super useful and convenient even for shows

Just used it at gigs for the first time on Saturday. I'm the drummer but the guitarist could turn round see the beats flashing if he was starting the song not me. Kept us all togeter neither dragging nor racing through two gigs and a long hard day.

Definitely one of my best purchases this year

Really love this product! Helps me maintain tempo in playing music which I have struggled with for years! Also a great companion when working out. I use it for timing between workout sets. Design is super sleek as well, great buy!

A life-saver

I am a singer-songwriter but due to an ear injury, I’ve been unable to hear the frequency of click tracks. The Core has been immensely useful and within a few weeks I’ve learnt how to master it. The Core is great and I love its potential.

A 5-star product for sure

I've got the tempos set in the app and it counts in all the songs for the band, we also link up on other projects so everyone with a Soundbrenner gets the beat. As a guitar player, I really dig the tuner and being able to tap a tempo into the watch and always having it with me is fantastic.

Quite satisfied

I’m enjoying the metronome function, and have yet to try the tuner. However, I would have liked it to have some health monitoring features such as step-count.

It does what it says it will do at a high level

The leather band is a comfort level better than rubber and plastic. It looks great too. Listen and play more music people! Thanks.
