These JLab Epic Lab Edition buds take music seriously. Very seriously. Hybrid dual drivers belt out a symphony of well-balanced, crystal-clear sound. Think rich bass and sublime highs. They're even tuned to the Knowles Preferred Listening sound curve - that's the tonal response curve we humans enjoy most when listening to music. Because everything sounds better in Hi-Res Audio, these buds support LDAC and AAC codecs, so you'll hear every note as clear as a bell. If the conversation next to you is spoiling your groove, switch on smart active noise-cancelling. It cleverly adapts and learns to mute the world around you so you can get lost in the beat.Good to know- Pick your presets, toggle ANC, and set volume limits on the JLab app- These buds use Bluetooth LE for brilliant sound that won't kill your phone battery- Pop them in the case between listens for up to 36 hours of playtime - or even more with ANC off- The case works with QI wireless chargers (sold separately), as well as USB-C- They play and pause automatically when you put them in and take them out with wear detect- Switch between calls on your phone and videos on your tablet with Multipoint Pairing- You'll love how good games and movies sound with support for Spatial Audio- Put them through their paces with IP55 sweat and dustproofing
