The wearers forget they're wearing them, ...the audience forgets that there are microphones involved ...and you'll soon forget what they cost.
Although all the other head-worn omni's I've used over the years have been significantly more expensive, NONE have survived equivalent usages as unscarred as the eight Samson SE-50's I've been using since they arrived from Sweetwater over six months ago...
Which would be irrelevant if they didn't sound any good. They do.
I've found them to sound nothing short of superb and would unhesitatingly recommend them for any SPOKEN WORD application.
In my experience, spending from a third more to twice as much will indeed get you a head-worn omni that will also handle the very loudest of percussive and/or sung bass transients without distortion, whereas the SE50's diaphragms won't.
(That's why I've deducted half a star.)
However, parting with that extra cash will also get you some headworn omni's that
a) Are nowhere near as comfortable,
b) Don't fit and stay in place nearly as well,
c) Won't as readily shrug off moisture and
d) Don't arrive "ready to plug into" nearly all belt-pack transmitters.
The Samson SE50 is also unique in that its "bowstring-style" behind one ear D-mount can both be stretched and moved around its armature to accommodate all shapes, sizes and acrobatics, with total freedom from the comfort and styling issues that attend other headworn systems.
In addition, the mic's boom will survive repeated bending and straightening, ...even to the extent of an "S-bend" shortening for youngsters.
One little "tip": ...A very carefully applied drop or two of clear silicone sealant (from the end of a toothpick or similar) onto the side of the miniature mic's capsule is a very effective way of retaining the tiny foam windgag.
That silicone "goo" is easy to scrape off and re-apply when replacement is eventually needed.
Although Samson (again, uniquely) includes spares and replacements are fairly cheap, I routinely do this to avoid the accidental mid-show loss of a "popper-stopper".
Once again, set and forget.
Which leaves but one quandary...
Can a mic (or anything else) be memorably forgettable?
