If size is the only reason to go the
Sennheiser route, one might care to look at the the UR1M from
Shure. It is even smaller than the SK5212 from
Sennheiser.
I have to disagree with howlingwolf on TA4Fs. They were not
Switchcraft's best invention... The knockoffs are worse than the real ones, but they are one of the major sources of issues with headsets
etc through our service dept. In contrast, those with microdot connectors seldom fail. There are microdot to TA4F adaptors available and these plus the microdots seem to be the best way of connecting.
Big gig last year we had some dropout issues with the Senny G2 IEMs. We have never had issues with
Shure PSM gear. This is a part of why we have an extensive
Shure inventory and only a handful of
Sennheiser... I'm sure that at one
point or more, Lectro would too have been considered... Their price
point is not as attractive down here for various reasons...
csheley, your antenna distributioon, which I assume is what you are talking about, in ultimately independent of manufacturer. The governing factors will be the bandwidth that the splitter is happy at and possibly you may need new antenna cables for an oddball receiver. Beyond that, manufacturer is no issue... Ditto for antennas.
