## Questions & Answers

**Q: Why aren't there any reviews from folks who paid for this item?**
A: I paid for it, and let me tell you, for what it is, it’s WORTH IT. It lasts awhile, and sound quality is actually pretty good! Only downside is the little rubber earbud that comes with it comes off quite easily but as long as you keep it snug and are aware of it it isn’t an issue.

**Q: Does this earbud have charging cable?  I see yes & no on the site.  Which is it?**
A: Yes it comes with a charging cable

**Q: Can you sllep with them on or does it fall off**
A: You could fall asleep with it in but there's always a chance of it falling out. 
Mine has even fallen out when I was Driving.
But for the most part it's alright.

**Q: Has anyone successfully paired these earbuds TOGETHER for surround sound? My phone will only play through one bud at a time.**
A: These ear bud are to be used one at time they are single ear buds.
