Classic wireless earbuds with 40 hours playtime This is the wireless age, baby, and Ravens are the classic style wireless earbuds. A single charge means you can listen for 8 hours at 50% volume, then re-charge them with the case four more times. For the math-challenged, that’s 40 hours total. But there’s nothing challenging about discovering all the things you can do with that kind of time: work out, binge-watch the show your friends are bugging you to watch, or just chill. The Ravens can power through it all.
