does it come with 1/4 jack adaptor ?

yes! come with 1/4 jack adaptor

This is the only listing I've seen for the Xvive u4 that mentions "built in limiter circuitry". Is this accurate?

I read the instructions and I don't see anything about a limited circuitry. I can tell you from experience as I play 4x times on Sunday and once on Wednesday that for a total of 5 hours a week. The unit works great. Myself and 2 other guitar players have their own pack and we all have wireless guitar packs as well and then there are 3 to 4 wireless microphones on stage. We don't get any interference from anything. We get great sound in our ears. The only down side to the unit is if you use the 1/4" connector then you will only have mono balance. If you have the ability to use the XLR end into a mixer then it might allow you to get each ear set up different instead of mono. The unit is built really good and solid and I don't have any complaints about it.

Can i use this directly to guitar headphone output?

yes，U4 can direct connect guitar effect headphone output

I have the m6 pro in ear monitors would these work for them

yes,work with TRS jack in ear monitors
