With the Skullcandy Indy ANC, you can hear more from your favorite songs in busy areas. The earbuds have noise canceling, so ambient noise is lightly reduced. That way, you don't have to raise the volume of your music in loud areas. Download the Skullcandy app and adjust the sound to your wishes via the equalizer. Thanks to this, you can listen to a personalized sound reproduction. With noise canceling turned on, the battery of the earbuds lasts for 5 hours. Are your earbuds empty? You can listen to 2 hours of music again after a 10-minute charge. Note: Skullcandy does include a charging cable, but no charger. Use your current accessories, or purchase them separately.
