## Questions & Answers

**Q: Are thes good for running or will they fall off too easily?**
A: thes don’t good for running but good sound

**Q: Will all of the functions of the in-line microphone & remote work with Spotify on an Android phone??**
A: Yes, the in-line mic and remote will work with any smart phone when paired via bluetooth. You can even double tap the power button to activate SIRI and Google Assistant.

**Q: Where do I get replacement ear pads for the BT221i headphones?**
A: Way late with this answer and I doubt the original person is still concerned about this but there is a person on eBay currently selling 5 pairs of replacement pads for these headphones for only 10 bucks!

**Q: Can these be hooked up via 3.5mm jack as well as Bluetooth?**
A: No, they are bluetooth only. Personally, I prefer the sound quality on the wired ones that they do - best value for money headphones you can buy. But I can sync these up with my watch over bluetooth so I don't have to take my phone when I go out running - handy.
