Hmm my information might be outdated but I don't think Bluetooth inears have low enough latency to be usable in the first place?
Skip the bluetooth and get wired! And get yourself an 8 foot headphone extension cable for the phones or in-ears so you don't stand up and they get ripped off your ears. 
hi,
despite that, I would like to ask why you want to usw IEM. If it was for home use only, I would allways use normal headphones. You get way more comfortable and good sounding ones for less money - compared to IEMs.
If you plan to use it live, which is allways a good idea, IEMs are the way to go. Unfortunately, you will have to spend money on this, since the soundquality in your ears mainly depends in the phones - and these can get quite expensive. I myself have used thomann earplugs for about 100€, which were ok-ish, at that time. I ended up with custom IEMs Form vision ears for 1.5k... But they are worth it! You can get wired headphone amp beltpacks from Fisher Amps, I use these too. Or go the wireless Route - again more expenses...
Bluetooth wont work, as already mentioned.
You asked for connections on your desk - I would simply plug the Kempers Output into one, or two channels, if you go stereo. Be careful not to overdrive the input. Then use the built-in headphone amp of the desk and listen to your guitar. From there on, you can develop your live monitoring system, if you planned to do so.

Oh dear, I need to sort it for a gig this weekend! Do you have wired IEM you can recommend? I don't think I'll be too far away from the desk so I should be ok with a wired connection.
hi,
i play wired all the time. Just taped a guitar and a microphone cable together, the latter for the monitor signal.
I use this one, works very well:

Best,

I also have the fisher stick with a twin cable. Very good product and very easy to adjust volume during a song.
Interesting products. Do they allow for stereo IEM?

You don't have any wired headphones laying around?

Stereo only as an unsymmetric signal. But I use it in mono.
Yes, I use it stereo.
