The person I need to get this for doesn't like the style of headset that comes with the XD-V75 so I need something else.
It's that person's "intended application" or "role" that's absolutely critical
[color=rgb(55,55,55)][font=Arial]My personal favourite for spoken word
applications, (of which I own twelve that I regularly use with my
eight Line 6 beltpacks, four being permanently double-windsocked for outdoors) is the Samson SE50: http://www.amazon.co...rds=Samson se50
In common with the (roughly 25% dearer) BP893cT4-TH that you mentioned, it's omni
directional, a type of headworn mic that is (for a variety of reasons) almost non-viable for sung
vocal applications, as Audio-Technica themselves "hint" in the following sales pitch: "The combination of stellar sound quality and functional design makes the Audio-Technica BP893cT4-TH ideal for theater productions, worship sound, and public speaking."
For singers, then, we need directional
TA4F-equipped headworns, such as those from the Countryman, MM Audio and DPA catalogs that you've mentioned.
Beyerdynamic also have both omni and
directional (very fine sounding) headset mics in their TG "Tour Group" range, (which should work with our beltpacks) but I suspect that your "client" may have the same objections to those as to the far cheaper offerings from Line 6. http://www.thomann.d...tqg_stecker.htm
As for DPAs, while I really love the d:fine's natural sound, I've had quite a few ruggedness problems (over the years) with their microdot connection system that's at one end of the eye-wateringly expensive DAD6010 adapter that's required for use with our beltpacks.
Also, as you'll see in this excellent (if slightly dated) document from Dan Cornett http://line6.com/support/docs/DOC-2252
there's no guarantee that other accommodations won't need to be made regarding some DPA models.
