I got this for 31 dollars once.  I don't know why it went down so much.  The one I got might have not been compatible with my phone( which was an LG Env2)  But this works well otherwise that is, until im using it!  It frequently disconnects during calls while on the phone for 15 minutes( sometimes it happens almost right away.  No matter how close I am to the phone ( which doesnt make sense because its fullly charged and supposed to last at least 5 hrs) I mean the no matter how good anything else is( sound,mic, etc, product build,features) it all depends on how stable its connectivity is to the phone!  I know alot of others gave good reviews on this but after reading about what many others have to say about the way this disconnects alot, I don't doubt it.  Ive had other bluetooth headsets and none of them ever had this problem.  The volume doesnt get that high for music, and the sound can be a little tinny at times.  I will be looking elsewhere for bluetooth headsets. Gotta have one that stays connected. Thats a must.
