## Questions & Answers

**Q: Why does Slumber not have a rechargable battery?**
A: We have chosen not to make our pillow speaker battery operated for a few reasons. Firstly, it would require regular battery maintenance and replacement, causing inconvenience when the sound doesn't work at night. Secondly, troubleshooting issues such as low battery, Bluetooth connection problems, or audio being paused can disrupt your sleep. Additionally, having a rechargeable battery near your bedding may not be the safest option.
