The new Soundcore earbuds with the Liberty 4 are being added by the company today. They are the first ones in this line to combine a stick design and dual dynamic drivers that Soundcore claims pushes the boundaries of sound.

The Liberty Air 2 Pro made our list of the best cheap earbuds last year, and the Liberty 3 Pro managed to impress for the price when we reviewed them in February, despite ANC that could use some improvement.

There are a few things that we haven't seen on every set of earbuds in this price range, and that's what the Liberty 4s feature. Not everyone is a fan of spatial audio features in headphones and buds, but these buds have it and try to align the sounds as you watch movies or listen to music while you have the feature turned on.

In case you don't have a watch, armband, or ring to monitor that kind of thing, they include an in- ear heart rate sensor that ties to a wellness app to keep track of daily data.

They also include Soundcore's HearID active noise cancellation, three sizes of ear tips, and 6 microphones that are supposed to help your voice come through clearly to people on the other end. Multipoint connections allow you to stay connected to both your phone and laptop at the same time. The Liberty 4 does not include aptX like their predecessors.

Up to 9 hours on a charge with normal use, 5 hours in spatial audio mode, 6 hours in LDAC mode and no noise cancellation, and up to 7 hours with just ANC on, depends on which feature you use.

The case can be used to fast charge them for 15 minutes or to charge them from empty to full in an hour. Soundcore says the Liberty 4 can be used for up to 28 hours in normal conditions.

The black version will be on sale at Soundcore.com, Amazon.com, and Best Buy by the end of October, and the white version will be on sale at the same time. On October 7th, Soundcore will sell the white set, and on October 17th, Amazon will sell it.
