Thanks for making me aware of this amazing instrument and its heritage! Both a leap forward and a throwback to techniques used to play the guitar's lute, lyre, harp and psaltery ancestors.

Greetings from down under...

It probably is a bit cheeky of me to "weigh in", given that I neither own, nor have experience of operating a Line 6 headset (I do own and operate eight XD-V70L's and regularly use the alternatives of up to eight Samson SE-50 headworn mics or four Line 6 THH12 modeling handhelds), ...but close inspection of the pix makes me think the Line 6's mic boom can be unclipped and reversed to achieve what you're after.

Given that other manufacturers' similar products (Countryman, DPA, Rode) offer this, I can't imagine Line 6 doing any less.

However, the main reason for my two cents' worth is to comment that, given a fully equipped Line 6 XD "kit" comes in at roughly half the cost of anything of similar ruggedness (with the bonus of frequency freedom), you'd still be "ahead" if you purchased another headset mic.

Performers that I've regularly "assaulted" with headworn gear over the last thirty years or so tell me that the single-ear only Samson SE-50 ($199 ...$1.00 change!) is the most comfortable and "stay put" arrangement that they've ever used.

Here's a link to it on Amazon:

It's omnidirectional, which is a mixed blessing.

Advantages:

Flat, uncoloured response and "tilt" positioning of the boom has given me a wonderful "one mic does it all" natural balance between vocal and acoustic instruments (harp, sitar, twelve-string etc.) when I've been called upon for "folkoric" re-enforcement via my HK Audio Elements rig. This very lack of "peakiness" also yields a surprising natural presence to intimate vocals.

Disadvantages:

No good whatsoever for "heavy metal" vocal levels. First, the miniature diaphragm will "hit bottom" yielding distortion when located close enough to the corner of the mouth to achieve isolation and second, it will not reject enough of ear-splitting levels from foldback wedges.

I hope my butting-in is of some use.

Yes indeedy,

Line 6 not only have a brilliant "answer man" with the most appropriate initials in the whole audio world, but they seem to have a knack for (almost invariably) pre-solving "real world" issues.

I'd be willing to bet that their headset mic will be just fine.

Should you eventually settle on another (for whatever reason), having theirs as a viable "spare" in your kit would be no bad thing, especially as, when I draw comparisons with other manufacturers, Line 6's pricing means that it was effectively "tossed in" as a free "sweetener".

Enjoy !
