The Sony LinkBuds S comes with a charging case that will recharge the internal batteries of the two ear phones.
If the ear buds are recharging slowly, or not at all, then you can check out this troubleshooting guide at Seeking Tech to see how you can potentially resolve your problem.
1. Before we begin, it is important to note that the ear buds will take up to 2 hours to fully charged. When it comes to the charging case, it can take up to 3 hours to recharge its battery.
2. To start off, make sure you are recharging the ear buds within a range of 59 °F to 95 °F (or 15 °C to 35 °C). Outside of this temperature range, the charging could slow down or even stop entirely.
3. Do not try to charge the ear buds or the charging case of the LinkBuds S if any of these parts are wet. Instead, you need to make sure that they are completely dry first.
4. Make sure that the charging ports of the ear phones and case aren’t dirty. If they are, then you can check out this guide to see how you can properly clean these ports.
5. You should also make sure that the ear phones are properly placed into their designated positions inside of the charging case.
The ear bud tips could end up preventing the charging ports from connecting to each other. In this case, you can try repositioning the tips are removing them from the ear buds.
6. When recharging the ear phones, make sure that you keep the top of the charging case closed in order to prevent wasted battery energy.
7. If you are recharging the Sony LinkBuds S case, then make sure you use the USB Type-C cable that came included in the box as another cable may not be compatible.
8. Furthermore, you should also make sure that the cable is firmly connected to the USB port of the charging case as well as its power source.
9. If you are connecting the other end of the USB Type-C cable to an USB AC adaptor, then then adaptor must have an output current of at least 0.5 A (or 500 mA).
10. If you are connecting the other end of the USB Type-C cable to a desktop computer, laptop, game console or any other device, then make sure that the power source is turned on.
Otherwise, a device in rest mode, sleep mode, hibernation mode or similarly named low-power state mode may not be able to supply power to the charging case.
11. You should also avoid connecting the other end of the USB Type-C cable to an USB hub or USB pass-through device. Instead, the cable should be directly connected to one of the USB ports on the power source.
12. If the power source has multiple USB ports, then you can try using a different one.
13. Moreover, you may want to consider resetting or factory resetting the Sony LinkBuds S as either of these actions may help the ear phones recharge normally again.
To see how you can do both, we recommend that you follow the steps laid out in this tutorial.
