A: You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.

**Q: How long does it take to fully charge the adapter?**
A: It only takes 1.5 hours to fully charge the adapter.

**Q: Can I connect my phone to the Relay via Bluetooth?**
