Unfortunately I had to either have the case off and listen to headphones, but I didn't want to risk damaging the connections so I went ahead and purchased some Bluetooth enabled headphones and they work well. One thing I have to say about this case is mine gets really hot when charging my phone from the case. Whether that's just my case being damaged over time just thought id let you know. All the best. Hope all is well with the current COVID situation. **Q: Hey, how long should it take to fully charge the battery case? Not sure if it's broken but it never seems to reach full battery capacity** A: It should take up to 2 hours to fully charge but before you charge the phone you must charge the charger **Q: Can you use normal headphones with an adapter?** A: Yes **Q: Can you stick a magnet to the back of the case?** A: because the charging box capacity is high, the strength of the magnet is not too strong .
