Sound comparison between 5 IEM systems (2x Sennheiser, 1x Phenyx Pro, 2x Relacart)

Since there are not much videos comparing different IEM systems I made a quick one.

I was looking to add a second unit to my trusty Sennheiser EW300 G3 system and got to try few.
I was pleasantly surprised by the Relacart PM-100D, it sounded second best to my G3 so, I bought it!
If there´s interest I will give updates on the PM-100D as I get to use it more in rehearsals and live.

Now, let´s get this channel back to retirement :)

Update.
First rehearsal with Relacart 100D went well. 0 interference and no glitching, really happy with it.
Was a little worried about volume because it seemed quieter than other systems but had the bodypack volume about 2/3 up and that was plenty loud for me.
Digital latency was not a problem (playing through HX Stomp + Tonex to Behringer XR18 digital console).
Will update again after first gig with it.
