Protected from rain and water splashes (but no showering!).

How the dB 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 Organisation:

  • 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 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!

FAQs

  • How long is the battery life?

    4+ days in watch mode, or 3+ hours metronome playback

  • Is it waterproof?

    It's splash resistant (IP65). This means it can withstand light rain or water splashes, for example while washing your hands. However, it can not withstand heavy rain, showers or water immersion.

  • Can I sync it to my DAW?

    Yes, DAW support is currently in beta. For more information please visit www.soundbrenner.com/daw-compatibility

  • Can I turn off the LED lights?

    Yes, you can customize the colors of the LED lights or turn them off completely!

  • Why can't I just use my other wearable, e.g. Fitbit or Apple Watch?

    We use a 7G ERM haptic motor powered by a special haptic driver. This creates vibrations unlike in other wearables. More distinct and precise & 700% more powerful than most devices. This powerful hardware is not just a gimmick that sounds cool, but a requirement for a vibrating metronome to work.

  • Where can I wear it?

    The silicone strap and the Italian leather strap (Core Steel only) are designed for the wrist. In addition, both versions come with a body strap that allows you to wear the Core on your arm, ankle, chest, shoulder or thigh.

  • What wrist sizes is it designed for?

    Fits wrists with 140mm - 210mm / 5.5 in - 8.3 in

  • What instruments can it tune?

    Currently guitar, bass guitar, ukulele and violin are supported. The tuner only works with the piezo contact microphone that requires a physical connection with your instrument.

    Tuning your instruments purely via audio is currently not supported.

  • What's the difference between the Pulse, Core and Core Steel?

    The Pulse is our entry level product that features just a vibrating metronome. You can change the rhythm on the device, but it has no screen so for precise adjustment you have to use the companion app. The Pulse has a longer battery life, but also a much bigger size than the Core. The body strap comes not included and is available for purchase separately.

    The Core doesn't just feature a vibrating metronome, but also a contact tuner, dB meter and smartphone notifications. It comes with a screen, so precise adjustments can be made right on the device. It is not just a music tool, but can also be used as your daily watch. The body strap comes included with each Core for free.

    The Core Steel has the exact same features as the Core. On top of that, it's made from a premium black full stainless steel casing and besides the silicone strap, it comes with an Italian leather strap. It also includes a bonus carrying pouch.

  • Is my phone compatible with it?

    For up to date compatibility information please visit www.soundbrenner.com/compatibility

  • How many devices can you sync at the same time via multi-player sync?

    You can sync up to 5 Soundbrenner wearables via Bluetooth to the same mobile device. You can sync just Pulse, just Core or a mix of both.

    If you want to sync more than 5 Soundbrenner wearables, you can link multiple mobile devices via a technology called Ableton Link that we support. You can then connect 5 Soundbrenner wearables to each linked mobile device. For more information check out our guide here: setup guide.

  • How do I charge it?

    The device comes with a USB charging cable that works with any regular USB port.

  • Is it safe when you have a pacemaker or other medical devices?

    It contains strong magnets that may interfere with some medical devices. We recommend to consult with your physician before using the product.

  • Do you ship internationally?

    Absolutely! We’re a global company and ship to almost every country in the world. To find out if we ship to you, simply initiate the checkout process and see if your country is available for selection.

  • How much does shipping cost and how long does it take?

    Simply initiate the checkout process and enter your address. Our system will tell you the shipping costs and give you an estimate for the duration.

  • Can I return it if I change my mind?

    Yes, you can return any item you purchased on our web store to us within 30 days of receipt and you will get your money back (excluding shipping costs). For more information check our terms of sale.

  • Do you offer a product warranty?

    Yes, we offer a 1 year warranty on all of our products. If your item has a defect due to a mistake on our part, we will send you a replacement free of charge. For more information check our terms of warranty.
