I have had the same problem with my BeatsX in the recent weeks, somehow I get it working again by following the below steps:
- Power the BeatsX with lightning cable
- When it is charging, press power button and center pause button for 10 seconds and let go the buttons
- It will blink red and white several times, and after unplugging the cable, the headphone works again
However, after some days, and after the BeatsX charged again for some times, that 3-white-blink problem may come again. I have had this problem in the recent weeks for at least three times already.
This is the 2nd times I have had problems with my BeatsX. I bought my BeatsX at Apple store around March 2017, and it broke down less than a month of purchase (weak red light during charging and won't turn on at all), so I brought it back to Apple and waited a few weeks for a replacement. After receiving the new replacement device from Apple, in less than two months, this 3-white-blink problem come and make it unusable again suddenly.
BeatsX is the first product I purchased under Beats brand. I've been using the BeatsX carefully and charged it with all genuine Apple accessories. However it keeps breaking down and disappointing me. I bought a Bluetooth headphone for leisure but not for trouble. This experience with the BeatsX is extremely disappointing. I have never bought any headphone which can break down so easily and frequently within just few months of purchase. I will probably never buy any Beats product again.
