Outstanding Mic, great quality/value
I love this headset. For the money, this was a great purchase -- and no hassles of packs on my belt!
I play in a Rock Cover Band, so i'm usually singing into a wired mic, but since I play with a Wireless setup for my Bass Guitar, I wanted a Wireless Headset -- but without the hassles of yet-another-Transmitter Pack (already got one for my guitar, but easily attached to my Guitar strap, not my belt).
This Samson Airline Micro fit the bill perfectly. it's so small and lightweight, I practically forget that I'm wearing it at all. Great Sound quality (just took a bit of tweaks on the Sound Board to make is sound as good as my wired mic on stage - a bit more on the bottom and mid-range). The fact that I can move the mic farther/closer from my mouth (for those background harmonies vs Lead Singing) was a great plus - would be more difficult with other headset types.
I see now that Samson now offers 4 different channels (it was only 3 when I bought mine), so that's a big plus - but my guitarist and I have switchable channels on our Guitar wireless setups, so it hasn't been a problem for us at all.
