The company’s latest is the Muse 5, a set of in-ear buds that are cheaper than their debut Apollo 7 option, but still come with a charging case and very respectable battery life.

Erato says that the Muse 5 are meant for listeners “with an active lifestyle who are always on the go.” To this end, the earphones use patented FitSeal Sleeves to stay put in the wearer’s ear.
