Yeah if you get lucky between both of the parts youll be able to make one work

Be mindful though most of the time they are defective it is the battery. Take my word, ive literally got a box full of defective units…

I’ve seen individual buds for sale on eBay

I prefer to repair when possible to avoid ewaste but the XM4s are a bit older and you can probably snag a replacement bud for around the cost of repair
