Soundwave Keychains
Sound wave keychains with QR code
Store a voice, a song, or a special moment and keep it alive forever. Our sound wave keychains with a QR code are the most modern and touching gift. We transform your audio message into a unique sound wave, which we engrave with absolute precision onto the keychain. Simultaneously, we create a functional QR code that, when scanned with any smartphone, plays the audio, allowing you and your loved ones to hear the magic of the moment again and again, at any time.
