One side of my beats solo3 does not work

Hey there, lidija112!

Thanks so much for using Apple Support Communities.

We want to help you get your Beats working! To start, we'd recommend working through resetting your Beats. This process is super easy and you can start here: Reset your Beats on-ear or over-ear headphones - Apple Support

If that doesn't work, you may want to look into having your Beats inspected potentially for service. You can learn more about this process here: Beats Repair - Official Apple Support

We hope that this information is helpful.

​Have a great day!
