Not bass heavy/BUT good for normal listens.

These Jaybirds aren't very bass heavy which some people like, but it's good for normal non bass songs or just to watch TV shows. These headphones come with an attachable 2-3 hr battery which is used to charge the main set which gives you about 2-3 hr as well. However, if you lose the attachable battery then you need to buy a new attachable battery since the main Bluetooth earphones doesn't have a charging input. If you blast the headphones on full volume the power drainage is really high. This is about 2 hrs to go from 100 charge to 0 and vise versa if you listen with them in a lower volume the battery will last longer. The product is advertised as 8 hours, but it's split for 4 hrs on the attachable battery and 4 hrs on the main headphones. To fully get the 4 and 4 hours you need to listen to them in a super low volume. So in reality if you usually listen full blast then you are getting about 2 hrs with the headphones and 2 hrs with the battery making it a total of 4 hours. Would highly recommend for a grandma or a grandpa, but not for a young person like myself.Read full review
