However, vocals and instruments sound overly harsh, while sibilants, like cymbals, are piercing. Out of the box, these buds have a very bright sound profile with lots of extra bass to complement hip-hop and EDM tracks. They're also comfortable and designed to stay in place during moderate workouts. Their battery lasts just over six hours with the ANC on, and they have two extra charges in their carrying case, so you can easily recharge them while on the go. This function can be static or track your head movements within the soundstage for a more immersive listening experience. They also have a Spatial Audio mode that creates a virtual soundstage while listening to music or movies. The best Soundcore earbuds we've tested are the Anker Soundcore Liberty 4 True Wireless. These noise cancelling earbuds are chock-full of premium features, which helps them stand out against similarly-priced competing models. Their ANC does a good job of isolating you from ambient chit-chat around the office, even if it doesn't do as well at reducing the low rumble of bus and plane engines or the high-pitched squeak from brakes.
