Festival tech for live music lovers

It's summer and music is in the air.

Festival-goers are benefiting from new technology that lets you pay for drinks using your wrist and new earbuds that let you hear music better than ever.

No matter where you end up at the show -- whether in front of the stage or in front of a speaker -- you'll be able to control how you hear live music with new high-tech earplugs.

Doppler Labs is developing the Here buds that connect wirelessly to a smartphone app so you can control the volume of the performance and adjust the levels.

"So that's everything from volume control, you can turn the volume of your real world up and down to five band EQ, adjust the bass, mids and trebles in your world," Noah Kraft, CEO and co-founder of Doppler Labs told CNET's Lexy Savvides.

The buds are designed to let you hear the world around you but dampen annoying noises, like car alarms or a crying baby.

"What we're able to do is identify that frequency range (and) say, look we want to let the other audio through but we're going to create anti-noise where the baby is crying so that does not make it through," Kraft explained.

At the Outside Lands festival in San Francisco, there's not just tech for your ears, but also your hands.

Guests used wristbands with radio frequency identification (RFID) chips to enter the festival and pay for drinks. Festival technicians also experimented with location-based beacons that sent smartphone alerts based on where a guest was on the grounds.

And to make sure that guests were connected well enough to upload pictures and video to social media, AT&T and Verizon set up cell sites on wheels. AT&T added 50 percent more LTE capacity with its cheese wheel antenna, which has ten times the capacity of the one it used to use.

And that is music to any connected music lover's ears.
