Feel the beat with a backpack that moves with your music

The SubPac M2 gives you feedback from the bass of the music you're listening to

When LeBron James was spotted wearing one as he was practicing on the court on ESPN, SubPac knew they were about to get a whole lot more interest coming their way.

They make the M2, a backpack-like device that connects to your music player over Bluetooth. When you're listening to music, the device will vibrate and pulsate along to the low-end frequencies in the song, meaning the bass and low sounds.

These are the sounds that get harder for us to hear as we age, and can also sound poor depending on the type of earphone or headphone you're listening through.

This pack on your back will let you experience music the way "producers and sound creators have spent so much time to master" according to SubPac CEO Todd Chernecki.

LeBron James isn't the only famous backer of the M2. Timbaland was in from as soon as he experienced it. He said "You’re going to change the word listen to feel". Expecting to bring that much change to how people consume music is a big statement, but SubPac seem convinced they can do it.

Music experience is moving in leaps and bounds, moving from a solitary experience of headphones to room filling sound coming from small speakers.

Now, becoming a full body experience is the next step. It's nearly similar to a virtual reality or 3D experience; suddenly the music is moving you, shaking you, making sound a much more sensory experience than just listening.

It can also make music more accessible, giving deaf people or those who are hard of hearing the opportunity to feel music like never before.

SubPac is now trying to get more and more artists to think about the low frequencies when they're recording and mastering their music. Having access to these frequencies like never before is letting artists rethink how people experience their music.

If more music gets released that's mastered to improve the low frequency, we could be about to go through a revolution with how people listen to music with thanks to a backpack.
