Enjoy nearly unlimited music with Urbanista Los Angeles Wireless Bluetooth Noise-Cancelling Headphones. The Powerfoyle in the headband generates energy from light and powers the headphones. Bright sunlight works the best, but artificial lights work too. And you don't have to be afraid of the dark, the Los Angeles have an 80-hour battery reserve. Their active noise-cancelling means you can completely immerse yourself in the music without distractions. And if you want to be aware of the world around you, Ambient mode will filter out the noise and let you hear the important stuff alongside your music. And they automatically pause the music when you take them off. Change a song, adjust the volume, answer a call, and then switch back to your music with the on-board controls. Or you can ask Siri or Google Assistant for help. And with on-ear detection the headphones will pause your music when you take them off.
