Hello there.
All units were measured and inspected before packaging. Without passing the Quality Control checks, the units will not be packed and shipped out.
Please send an e-mail to
Support@Linsoul.com with your order number, LINSOUL-XXXX, and attach a video to demonstrate the problem faced.
In that video, please show us how the left earbud has a "dead 2-pin connector" by pairing it with the left side of the cable connector first. After that, switch it to pair it with the right side of the cable connector.
Please also use a common streaming platform (e.g. Spotify) and state the tested songs used.
If the video file is too big, upload it onto Google Drive and send us the shareable link.
Once you have sent us the e-mail, you should receive a ticketing number via e-mail again.
We will get back to you soonest.
Thank you very much.
