## Product: BKM400 Wireless TV Headphones
**Brand:** Tianfucen

The BKM400 wireless TV headphones have a pretty decent battery life, offering up to 15 hours of playtime on a full charge. That should be more than enough for those long binge-watching sessions or using them throughout the day. 

Keep in mind, the manufacturer suggests fully charging them before you use them for the first time to make sure the battery lasts over time.

If you run into any connection issues, maybe give some other options a try, like optical or RCA. These might work better for you, and powering the transmitter from an external source instead of the TV’s USB port could help stabilize the connection. This approach has helped some folks get better performance with different TV brands.

For the best experience, we recommend checking out the setup guide that comes with the headphones for detailed instructions based on your connection. Also, tweaking your TV’s audio settings to match the headphones can make a big difference in sound quality.

If you're still having trouble, it might be a good idea to reach out to [Tianfucen](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dtianfucen%26tag%3Dssw.ans.tx-1-20)’s customer support. They can help you figure out any complex issues and guide you through troubleshooting steps.

So overall, with a bit of setup, these headphones should give you a solid audio experience and pretty reliable battery life.
