## Description

How to operate to get STEREO SOUND through any two earbuds paired: 1. First turn off the bluetooth of the mobile phone, disconnect the earbuds from the mobile phone, 2. Then press the two earbuds buttons at the same time to turn on the power of the two earbuds at the same time, 3. Waiting for 5 seconds, then double-click any earbud button, and the two earbuds are successfully paired, 4. And turn on bluetooth of the phone, find the Bluetooth name, connect the earbuds and enjoy it. How to change the language? Disconnect the Bluetooth of the mobile phone, power on the earbud, then double-click five times quickly, and the language will be changed

Review: I listen to a lot of audiobooks and podcasts and this tiny earbud is great. I've bought several of the same design because they fit my ear very well without the rubber tip. The sound is fine and the battery life is unbelievably long, often more than 8 hours. The one flaw in the design is that the two halves are vulnerable to separating and it's very hard to put them back together. This has happened to several of the previous ones like this that I've bought from different sellers. But so far this one is very solid!
Review: Perfect size sound is good nice product

## 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.
