WTB: Sony wf-1000xm4 / xm5

Looking for a decent pair of BT buds to use with my galaxy tablet and phone. So far as I can tell either the xm4 or 5 would be a good choice. Before spending $2-300 on a pair new thought I would see if any of you fine people had a pair laying around you're willing to get rid of.
I haven't used the forums much the past year or two as I have been busy with work and remodeling a house but so i feel bad that my first post back is me asking for help but I appreciate it either way.

Thanks!

 

I have bought 2 pairs of xm4s from Secondipity on eBay: https://www.ebay.com/itm/265230176953 Both sets have worked flawlessly and come with a 2-year Allstate warranty if not.

 

Found, please close!
Thanks!
