La calidad de audio es bastante buena (dentro del precio) por lo que no vas a sentir que has perdido el dinero. Se siente la calidad del producto - aunque sean de plástico - y eso se agradece.

## Questions & Answers

**Q: My earbuds are charged, blue tooth is on but not synching.  Has anyone else had this problem?**
A: Try resetting your earbuds if you have taken off the protective film already on your buds connector pins. Put them in the case and hold the touch controls at the same time on each bud for 8 seconds you'll see the case flash 3 times. You should have them reset at this point. Then pair again. Hope this helps

**Q: can only one at a time be paired and used with a phone?**
A: If your thinking to just use one and leave the other in the case then yes, I alternate mine in and out all the time, but if your thinking to keep one and then give one to friend to connect to a different device, I don't think so...

**Q: I just got my pair. How do i know when the case needs to charge?**
A: It'll flash red on the front. Everytime you or them away it'll glow white/silver.. That's charging them. When you close the lid it'll turn the buds off automatically. When the car needs to be charged it'll flash red when you place the buds in the case and close the lid.

**Q: Do these stream in AAC codex?**
A: They are supported by both aac when not making calls and such when making calls or using mic

### ⭐ Niet werkende earbud
*by A***N on 26 February 2025*

Een oortje werkte niet. Ik heb contact opgenomen met de fabrikant maar dat was een intense digitale communicatie (alsook verzending) waarin er getwijfeld werd aan mijn oprechtheid betreffende het defecte product. Hopelijk ontvang ik snel een werkende set.
