This battery lasted four months. My husband likes the form and at times is hard to find in the stores They are comfortable and quick to put on. I also damaged my ankle due to a fall early 2020. Beautiful dress. Its nice to have volume, play/pause and skip/reverse track function buttons on the actual speaker. I like the instant playback from phone to speaker. Especially so with acoustic music. You have to restart it. I really hope they stay charging this time because they are nice headphones for the money.
