The only '
headset' that
Shure makes are the WH20, WH30 which as mentioned are huge for 'theater' use and more suited for bands and groups like Madonna, Bieber or Hanson..and they are not 'great' having used a few...
Shure also makes a WCM16 which is a
bit smaller and could be used for some musicals...but appears suited mostly for speakers and bands...but not much to say more since I have not tried one of those yet on a show. The WL184's are just utter junk and far too big for theater use and they have a huge handling noise issue I have always disliked IMO--I hate using them even on talking heads. You can do far better with other mic's that are more flexible and less obtrusive today.
The cheaper theatrical headsets are by
Point Source--and having used a few on a couple of shows they are surprisingly not bad sounding for general use in HS shows...and they are comparable to affordable depending on what model you get (and they now make one--their CO 7 model, that has a
boom arm that is 'unbreakable'...so they claim). But for really fine or pro headsets you're limited to a few like Countryman and
Audio Technica and Sennheiser--but all of those take you far from that price range of $100 and most are far too delicate and easily broken if not professionally cared for by the users & techs.
You can get almost any miniature mic or
headset from almost any mfg wired to the TA4F or
Lemo connectors for your
shure wireless, so that is not a huge issue to worry about. For high school in all honesty I have done just fine with WL93's on deep budget shows (which come in black or tan) or WL50's...and to that you can always get better quality and sound with AT miniature lavs or the Countryman B6 or B3 or the
Sennheiser MKE II's
etc or go crazy and splurge the $$ with the dpa's and so on. They can be used in theatrical applications and hidden, or can be applied like a regular
lavalier mic with clip and perform perfectly. For musical theater I use and like the E6..and the new E2's are very nice (but you NEED that
windscreen for those--grr!)...but not everyone can afford to have a dozen of those including backups, AND the fact of the matter is I don't always NEED to use those...when I can use a WL93 or a WL50 or B3 instead. It comes down to the fact that you don't 'have' to have those high dollar head worn mics for good theater or choir uses....especially in high school shows. For theatrical uses just take your best miniature mic like a WL93 or B3 or B6 or MKE II
etc etc, and for 'headsets' you simply take those and some
wire, foam & heatshrink and
build your own earsets....or get thin elastic bands to make halo rigs and so on...or you can directly attach...it really makes it more versatile and flexible and budget saavy
IMO to have these miniature lav style mics and be able to adapt to the need of the show and actor and the budget over a
headset...because if you can't afford to have or risk to use a
headset for some reason, you can always place the mic in other more securable locations or
adapt it to fit for costume or for visability....but if you stick with just a straight forward
headset mic like an E6 you remove that flexibility and option. So the other consideration here is in durability--where a Countryman B3, a 93 or a WL50 will last me several years with good basic care and it will be flexible for me to use it many ways--an E6
headset may last me 1-2 years or less depending on how it gets used/abused and handled.... So repeat replacement costs and frequency factors in here
IMO for what is more durable for your application and for your tech saavy students...
In that price range--those are your best options
IMO... Its not always the 'best gear' or a certain brand that makes good sound--you can have the best gear possible and it still sound terrible---because it all comes down to how it is used and how well the
mixer/operator knows his stuff. A good sound guy with experience can make a $70 WL93 mic sound great...and a bad sound guy can make a $600 E6 scream with
feedback and pops and
distortion.. I would focus more on the training fundamentals and uses when it comes to High School kids and leave the higher $$$$ money mics for those who can afford the replacements...
JMO...good luck....
